[`@match` only works on the protocol/scheme, host, and pathname of a URL.][1]  

To trigger off the query parameters, you can either use `@include` or use `@match` and also test the URL yourself.  
Note that the `@match` approach performs faster.
  
With `@include`, you can use a regex syntax. See, also [Include and exclude rules][2].

In this case, use **either:**

    ...
    // @include  /^https?://example\.com/page\.php*key1=value1*/
    // ==/UserScript==

&lt;br&gt;
**Or:**

    ...
    // @match *://example.com/page.php*
    // ==/UserScript==
    
    if (/\bkey1=value1\b/.test (location.search) ) {
        // DO YOUR STUFF HERE.
    }

According to the documentation for `@match`, it doesn&#39;t appear that query string parameters are something the Greasemonkey engine will match on:

https://developer.chrome.com/extensions/match_patterns.html

This is an example of what I need to do:

    var myarray = [5, 10, 3, 2];

    var result1 = myarray[0];
    var result2 = myarray[1] + myarray[0];
    var result3 = myarray[2] + myarray[1] + myarray[0];
    var result4 = myarray[3] + myarray[2] + myarray[1] + myarray[0];

so all that would output 5, 15, 18, 20

but instead of writing out all the vars like that, I want it to say something like:

    var result = arrayitem + the sum of any previous items 

Does that make sense? Is that possible? How do I do that? 

Creating an array of cumulative sum in javascript

I&#39;m running into a generics problem with Mockito and Hamcrest.

Please assume the following interface:

    public interface Service {
        void perform(Collection&lt;String&gt; elements);
    }

And the following test snippet:

    Service service = mock(Service.class);

    // ... perform business logic

    verify(service).perform(Matchers.argThat(contains(&quot;a&quot;, &quot;b&quot;)));

So I want to verify that my business logic actually called the service with a collection that contains &quot;a&quot; and &quot;b&quot; in that order.

However, the return type of `contains(...)` is `Matcher&lt;Iterable&lt;? extends E&gt;&gt;`, so `Matchers.argThat(...)` returns `Iterable&lt;String&gt;` in my case, which naturally does not apply to the required `Collection&lt;String&gt;`.

I know that I could use an argument captor as proposed in https://stackoverflow.com/questions/17174192/hamcrest-hasitem-and-mockito-verify-inconsistency, but I would very much like not to.

Any suggestions!
Thanks!


Mockito and Hamcrest: how to verify invocation of Collection argument?

I&#39;m working on a script that must be executed in a certain page, depending on the parameters it has. The URL is like this:

```lang-txt
http://example.com/page.php?key1=value1&amp;key2=value2&amp;...
```

And I need to match it when `page.php` has the `key1=value1` among its parameters.

Now I&#39;m using

```lang-txt
@match http://example.com/page.php?key1=value1&amp;*
```

But it doesn&#39;t match if `page.php` has no other parameters. It also won&#39;t match if `key1` is not the first parameter either.

Is there any way to match a page according to a parameter?

Greasemonkey/ Tampermonkey @match for a page with parameters

I'm working on a script that must be executed in a certain page, depending on the parameters it has. The URL is like this:
<pre><code class="hljs language-ini">http://example.com/page.php?key1=value1&#x26;key2=value2&#x26;...
</code></pre>
And I need to match it when <code>page.php</code> has the <code>key1=value1</code> among its parameters.
Now I'm using
<pre><code class="hljs language-less">@match http://example.com/page.php?key1=value1&#x26;*
</code></pre>
But it doesn't match if <code>page.php</code> has no other parameters. It also won't match if <code>key1</code> is not the first parameter either.
Is there any way to match a page according to a parameter?

Basically, I am wondering if there is a way to automatically run a function when an element becomes hidden or visible, not on a user click but automatically in another script.

I don&#39;t want this to just run one time, because the elements (such as a slider) constantly change from visible to hidden.

Would this be something that jQuery can do with bind? Such as binding the element&#39;s visibility to a function (I don&#39;t know how to write this)

If you need me to elaborate more on what I&#39;m trying to do, let me know. Thanks

Pseudocode: 

	$(&#39;#element&#39;).bind(&#39;display:none&#39;, function);
	function(){
		//do something when element is display:none
	}
	
	$(&#39;#element&#39;).bind(&#39;display:block&#39;, function2);
	function2(){
		//do opposite of function
	}

The code work, but I&#39;m having a problem setting transparent background to the canvas with three.js. I use:

I have checked there are no problem.

now in add.ctp file I adder 

    &lt;input type=&quot;file&quot; multiple /&gt;

In output I am seeing the file type field.Now when I clicked on this field and upload a image then mojila bug given me a error.That is 

 document.querySelector(...) is null error 

I have no idea about this error.In here why saying queryselector is null?



document.querySelector(...) is null error

While I am not new to web development, I am quite new to to client-side MVC frameworks. I did some research and decided to give it a go with EmberJS. I went through the TodoMVC guide and it made sense to me...

I have setup a very basic app; index route, two models and one template. I have a server-side php script running that returns some db rows.

One thing that is very confusing me is how to load multiple models on the same route. I have read some information about using a setupController but I am still unclear. In my template I have two tables that I am trying to load with unrelated db rows. In a more traditional web app I would have just issued to sql statements and looped over them to fill the rows. I am having difficulty translating this concept to EmberJS.

**How do I load multiple models of unrelated data on the same route?**

I am using the latest Ember and Ember Data libs.

# Update
although the first answer gives a method for handling it, the second answer explains when it&#39;s appropriate and the different methods for when it isn&#39;t appropriate.

EmberJS: How to load multiple models on the same route?

I&#39;ve looked on Stack Overflow ([replacing characters.. eh][1], [how JavaScript doesn&#39;t follow the Unicode standard concerning RegExp][2], etc.) and haven&#39;t really found a concrete answer to the question &quot;_How can JavaScript match accented characters (those with diacritical marks)?_&quot;

I&#39;m forcing a field in a UI to match the format: `last_name, first_name` *(last [comma space] first)*, and I want to provide support for diacritics, but evidently in JavaScript it&#39;s a bit more difficult than other languages/platforms.

This was my original version, until I wanted to add diacritic support:

`/^[a-zA-Z]+,\s[a-zA-Z]+$/`

Currently I&#39;m debating one of three methods to add support, all of which I have tested and work (at least to some extent, I don&#39;t really know what the &quot;extent&quot; is of the second approach). Here they are:

 Explicitly listing all accented characters that I would want to accept as valid (lame and overly-complicated):
--

   ---

    var accentedCharacters = &quot;&#224;&#232;&#236;&#242;&#249;&#192;&#200;&#204;&#210;&#217;&#225;&#233;&#237;&#243;&#250;&#253;&#193;&#201;&#205;&#211;&#218;&#221;&#226;&#234;&#238;&#244;&#251;&#194;&#202;&#206;&#212;&#219;&#227;&#241;&#245;&#195;&#209;&#213;&#228;&#235;&#239;&#246;&#252;&#255;&#196;&#203;&#207;&#214;&#220;Ÿ&#231;&#199;&#223;&#216;&#248;&#197;&#229;&#198;&#230;œ&quot;;
    // Build the full regex
    var regex = &quot;^[a-zA-Z&quot; + accentedCharacters + &quot;]+,\\s[a-zA-Z&quot; + accentedCharacters + &quot;]+$&quot;;
    // Create a RegExp from the string version
    regexCompiled = new RegExp(regex);
    // regexCompiled = /^[a-zA-Z&#224;&#232;&#236;&#242;&#249;&#192;&#200;&#204;&#210;&#217;&#225;&#233;&#237;&#243;&#250;&#253;&#193;&#201;&#205;&#211;&#218;&#221;&#226;&#234;&#238;&#244;&#251;&#194;&#202;&#206;&#212;&#219;&#227;&#241;&#245;&#195;&#209;&#213;&#228;&#235;&#239;&#246;&#252;&#255;&#196;&#203;&#207;&#214;&#220;Ÿ&#231;&#199;&#223;&#216;&#248;&#197;&#229;&#198;&#230;œ]+,\s[a-zA-Z&#224;&#232;&#236;&#242;&#249;&#192;&#200;&#204;&#210;&#217;&#225;&#233;&#237;&#243;&#250;&#253;&#193;&#201;&#205;&#211;&#218;&#221;&#226;&#234;&#238;&#244;&#251;&#194;&#202;&#206;&#212;&#219;&#227;&#241;&#245;&#195;&#209;&#213;&#228;&#235;&#239;&#246;&#252;&#255;&#196;&#203;&#207;&#214;&#220;Ÿ&#231;&#199;&#223;&#216;&#248;&#197;&#229;&#198;&#230;œ]+$/

 - This correctly matches a last/first name with any of the supported accented characters in `accentedCharacters`.

---

My other approach was to use the `.` character class, to have a simpler expression:
--

    var regex = /^.+,\s.+$/;

 - This would match for just about anything, at least in the form of: `something, something`. That&#39;s alright I suppose...

---

The last approach, which I just [found][3] might be simpler...
--

    /^[a-zA-Z\u00C0-\u017F]+,\s[a-zA-Z\u00C0-\u017F]+$/

 - It matches a range of Unicode characters - tested and working, though I didn&#39;t try anything crazy, just the normal stuff I see in our language department for faculty member names.

---

Here are my concerns:

1. The first solution is far too limiting, and sloppy and convoluted at that. It would need to be changed if I forgot a character or two, and that&#39;s just not very practical.

2. The second solution is better, concise, but it probably matches far more than it actually should. I couldn&#39;t find any real documentation on *exactly* what `.` matches, just the generalization of &quot;any character except the newline character&quot; (from a table on the [MDN][4]).

3. The third solution seems the be the most precise, but are there any gotchas? I&#39;m not very familiar with Unicode, at least in practice, but looking at a [code table][5]/[continuation of that table][6], `\u00C0-\u017F` seems to be pretty solid, at least for my expected input.

  - Faculty won&#39;t be submitting forms with their names in their native language (e.g., Arabic, Chinese, Japanese, etc.), so I don&#39;t have to worry about out-of-Latin-character-set characters

---

Which of these three approaches is most suited for the task? Or are there better solutions?

Concrete JavaScript regular expression for accented characters (diacritics)

I have the following error:

&gt; Warning: preg_replace(): Unknown modifier &#39;]&#39; in xxx.php on line 38

This is the code on line 38:

    &lt;?php echo str_replace(&quot;&lt;/ul&gt;&lt;/div&gt;&quot;, &quot;&quot;, preg_replace(&quot;&lt;div[^&gt;]*&gt;&lt;ul[^&gt;]*&gt;&quot;, &quot;&quot;, wp_nav_menu(array(&#39;theme_location&#39; =&gt; &#39;nav&#39;, &#39;echo&#39; =&gt; false)) )); ?&gt;

How can I fix this problem?


Warning: preg_replace(): Unknown modifier

I&#39;m coming from Python, so I&#39;m probably just not looking at this the right way. I&#39;d like to create a fairly complicated regex and be able to access the fields match by name. I can&#39;t seem to find a good example. The closest I&#39;ve managed to get is this:

    package main

    import (
      &quot;fmt&quot;
      &quot;regexp&quot;
    )

    var myExp = regexp.MustCompile(`(?P&lt;first&gt;\d+)\.(\d+).(?P&lt;second&gt;\d+)`)

    func main() {
      fmt.Printf(&quot;%+v&quot;, myExp.FindStringSubmatch(&quot;1234.5678.9&quot;))

      match := myExp.FindStringSubmatch(&quot;1234.5678.9&quot;)
        for i, name := range myExp.SubexpNames() {
            fmt.Printf(&quot;&#39;%s&#39;\t %d -&gt; %s\n&quot;, name, i, match[i])
        }
        //fmt.Printf(&quot;by name: %s %s\n&quot;, match[&quot;first&quot;], match[&quot;second&quot;])
    }

The commented out line is how I would expect to access the named fields in Python. What&#39;s the equivalent way to do this in go?

Or if I need to convert the match to a map, what&#39;s the most idiomatic way in go to make and then access the map?




Using named matches from Go regex

Let&#39;s say I have the string

    &quot;12345&quot;

If I `.match(/\d{3}/g)`, I only get one match, `&quot;123&quot;`. Why don&#39;t I get `[ &quot;123&quot;, &quot;234&quot;, &quot;345&quot; ]`?

How can I match overlapping strings with regex?

I&#39;m looking for a neat regex solution to replace

 - All non alphanumeric characters
 - All newlines
 - All multiple instances of white space

With a single space

---

For those playing at home (**the following does work**)

    text.replace(/[^a-z0-9]/gmi, &quot; &quot;).replace(/\s+/g, &quot; &quot;);

My thinking is *regex* is probably powerful enough to achieve this in one statement. The components I think I&#39;d need are

 - `[^a-z0-9]` - to remove non alphanumeric characters 
 - `\s+` - match any collections of spaces
 - `\r?\n|\r` - match all new line
 - `/gmi` - global, multi-line, case insensitive

However, I can&#39;t seem to style the regex in the right way (**the following doesn&#39;t work**)

    text.replace(/[^a-z0-9]|\s+|\r?\n|\r/gmi, &quot; &quot;);

    1x05

Replace all non alphanumeric characters, new lines, and multiple white space with one space

I would like to simulate a whole click not just 

    document.getElementsByClassName()[0].click();

How do I do that?  Search results all seem to be about handling such events, not triggering them.



Simulating a mousedown, click, mouseup sequence in Tampermonkey?

The [GreaseSpot page on metadata blocks][1] says that the two are very similar but `@match` &quot;sets more strict rules on what the `*` character means.&quot;  GreaseSpot then proceeds to [teach][2] using `@include`, but Chrome examples like [this][3] generally seem to use `@match` and indicate that `@include` is only supported for compatibility purposes; `@match` is preferred.

[Apparently][3], `@include google.*` can run on google.evil.com while `@match google.*` cannot.  
That one example is not sufficient to really see how the wildcards behave differently between these two, and better explanations are sought in answers here.

New GreaseMonkey scripts (Firefox) use `@include` by default while new TamperMonkey scripts (for e.g. Chrome) use `@match` by default.

What exactly are the differences between these two?

For example, how does each one handle wildcards?  
Are there differences in cross-browser compatibility?  
What reasons would someone have for choosing to use one over the other?

What is the difference between @include and @match in userscripts?

I am trying to make a script run when &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;e&lt;/kbd&gt; is pressed.  
How can Tampermonkey fire on a simultaneous ctrl, alt, and e key?

I have tried `ctrlKey`, and `altKey`.  I&#39;ve found nothing that works.  
How can I edit the script below to fire on &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;e&lt;/kbd&gt;, instead of just &lt;kbd&gt;e&lt;/kbd&gt;?

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-js --&gt;

    (function() {
      document.addEventListener(&quot;keypress&quot;, function(e) {
        if (e.which == 101) {
          var xhttp = new XMLHttpRequest;
          xhttp.onreadystatechange = function() {
            4 == xhttp.readyState &amp;&amp; 200 == xhttp.status &amp;&amp; eval(xhttp.responseText)
          }, xhttp.open(&quot;GET&quot;, &quot;http://127.0.0.1:2337/inject&quot;, !0), xhttp.send();
        }
      });
    })();

Detecting combination keypresses (Control, Alt, Shift)?

I am writing a script which logs into my college network when the login page is loaded. 

The code looks as follows

    // ==UserScript==
    // @name       My Fancy New Userscript
    // @namespace  http://use.i.E.your.homepage/
    // @version    0.1
    // @description  enter something useful
    // @match      &lt;College login page&gt;
    // @copyright  2012+, You
    // ==/UserScript==    
    $(document).ready(function() {
            
        var usr=document.getElementsByName(&quot;username&quot;);
            
        var pass = document.getElementByName(&quot;password&quot;);
            
        usr.value=&quot;usrname&quot;;    
        pass.value=&quot;password&quot;;    
            
        var submitButton = document.querySelector (&#39;input[type=&quot;submit&quot;][value=&quot;Login&quot;]&#39;);
                        
        var clickEvent  = document.createEvent (&#39;MouseEvents&#39;);
                        
        clickEvent.initEvent (&#39;click&#39;, true, true);
                        
        submitButton.dispatchEvent (clickEvent);
        
        });

The console shows a error saying

    $ is not defined

Can someone tell me what is going on here?





Trying to load jquery into tampermonkey script

I would like to debug a Tampermonkey script with Chrome&#39;s console, but I can&#39;t find my script in the list..

![enter image description here][1]

Am I doing something wrong, or is it just that the Tampermonkey scripts don&#39;t appear there? And in that case, how can I debug it?

Debug tampermonkey script

I&#39;m looking for a way to run ECMAScript 6 code in my browser&#39;s console but most browsers don&#39;t support functionality that I&#39;m looking for. For example Firefox is the only browser that supports arrow functions.

Is there a way (extension, userscript, etc.) I can run these features on Chrome?
