You can do a relative redirect:

    window.location.href = &#39;../&#39;; //one level up

or

    window.location.href = &#39;/path&#39;; //relative to domain

If you use `location.hostname` you will get your domain.com part. Then `location.pathname` will give you /path/folder. I would split `location.pathname` by / and reassemble the URL. But unless you need the querystring, you can just redirect to `..` to go a directory above.

https://developer.mozilla.org/en-US/docs/Web/API/Location/assign

* `window.location.assign(&quot;../&quot;);` // one level up
* `window.location.assign(&quot;/path&quot;);` // relative to domain

 
`     &lt;a href=&quot;..&quot;&gt;no JS needed&lt;/a&gt;`

`..` means parent directory.

I&#39;m trying to redirect my current web site to other section on the same page, using JavaScript.  This follow code work for me:


    location.href=&#39;/otherSection&#39;

try following js code

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-js --&gt;
    location = &#39;..&#39;

&lt;!-- end snippet --&gt;



How would it be possible to generate a random, unique string using numbers and letters for use in a verify link? Like when you create an account on a website, and it sends you an email with a link, and you have to click that link in order to verify your account

How can I generate one of those using PHP?

How to generate a random, unique, alphanumeric string?

We have a big application on the site and we have a few links which are, let&#39;s say blue color like the blue links on this site. Now I want to make some other links, but with lighter color. Obviously I can just do simply by the hex code adding in the CSS file, but our site lets user decide what colors they want for their customized profile/site (like Twitter). 

So, my question is: can we reduce the color by percentage?

Let&#39;s say the following code is CSS:

    a {
      color: blue;
    }
    
    a.lighter {
      color: -50%; // obviously not correct way, but just an idea
    }
    
OR
    
    a.lighter {
      color: blue -50%;  // again not correct, but another example of setting color and then reducing it
    }

Is there a way to reduce a color by a percentage?

My problem is that I want to redirect via JavaScript to a directory above.

**My code:**

    location.href = (location.href).substr(0, (location.href).lastIndexOf(&#39;folder&#39;))

The URL looks like this:

`example.com/path/folder/index.php?file=abc&amp;test=123&amp;lol=cool`

The redirect affect just this:

`example.com/path/&amp;test=123&amp;lol=cool`

But want to have this:

`example.com/path/`

How can I do it?

There are many MD5 JavaScript implementations out there. 
Does anybody know which one is the most advanced, most bugfixed and fastest? 

I need it for [this][1] tool.

I have a menu bar with hover effects, and now I want to place a transparent image with a circle and a &quot;handdrawn&quot; text over one of the menu items. If I use absolute positioning to place the overlay image above the menu item, the user will not be able to click the button and the hover effect will not work. 

Is there any way to somehow disable mouse interaction with this overlay image so that the menu will keep on working just as before even though it&#39;s beneath an image?

Edit:

Because the menu was generated with Joomla I could not tweak just one of the menu items. And even if I could, I did not feel a Javascript solution was appropriate. So in the end I &quot;marked&quot; the menu item with an arrow outside the menu-item element. Not as nice as I had wanted it to be, but it worked out okey anyway.

Ignore mouse interaction on overlay image

Which characters can be used for naming a JavaScript variable?

I want to create a small &quot;extension library&quot; for my non-JavaScript users here at work (who all seem to be squeamish when it comes to the language).  I love how jQuery and Prototype have both use the `$` dollar sign, and since I use jQuery, I&#39;m looking for another nice single-character symbol to use.  

I realize that I could just test out a number of characters, but I&#39;m hoping to narrow down my list of characters to start with (in consideration of  future integration with another popular library, perhaps).

What characters are valid for JavaScript variable names?

Is there any way to hide a column in a jqGrid table, but have it show as read-only when the row is edited in the form editor modal dialog?

Hidden Columns in jqGrid

Here&#39;s my issue - I need to dynamically download several scripts using jQuery.getScript() and execute certain [JavaScript][1] code after all the scripts were loaded, so my plan was to do something like this:

    function GetScripts(scripts, callback)
    {
      var len = scripts.length
      for (var i in scripts)
      {
        jQuery.getScript(scripts[i], function() 
        {
          len --;
          // executing callback function if this is the last script that loaded
          if (len == 0)
            callback()  
        })
      }
    }

This will only work reliably if we assume that script.onload events for each script fire and execute sequentially and synchronously, so there would never be a situation when two or more of the event handlers would pass check for (len == 0) and execute callback method.

So my question - is that assumption correct and if not, what&#39;s the way to achieve what I am trying to do?

Is JavaScript multithreaded?

Java EE has [`ServletRequest.getParameterValues()`][1].

On non-EE platforms, [`URL.getQuery()`][2] simply returns a string.

What&#39;s the normal way to properly parse the query string in a URL when *not* on Java EE?  

----------

It is popular in the answers to try and make your own parser.  This is very interesting and exciting micro-coding project, but ***I cannot say that it is a good idea***.

The code snippets below are generally flawed or broken. Breaking them is an interesting exercise for the reader. *And to the hackers attacking the websites that use them*.

Parsing query strings is a well defined problem but reading the spec and understanding the nuances is non-trivial. It is far better to let some platform library coder do the hard work, and do the fixing, for you!

I&#39;ve searched for hours, but I couldn&#39;t find a solution for this.

    window.onbeforeunload = warn;

This doesn&#39;t work:

        
    function warn (e) 
    { 
       var destination = e.href;
       alert(destination );
    }
Okay, so to clear the things. If the user clicks on a link on the page itself, it is easy, because you can add an eventhandler to all of the links onclick event, but. I want to catch the address, what the user types into the url box of the browser.

How can I get the destination URL for the onbeforeunload event?

If I do

    url = &quot;http://example.com?p=&quot; + urllib.quote(query)

1. It doesn&#39;t encode `/` to `%2F` (breaks OAuth normalization)
2. It doesn&#39;t handle Unicode (it throws an exception)

Is there a better library?




How can I percent-encode URL parameters in Python?

What is the best way that I can pass an array as a url parameter? I was thinking if this is possible: 

    $aValues = array();

    $url = &#39;http://www.example.com?aParam=&#39;.$aValues;

or how about this:

    $url = &#39;http://www.example.com?aParam[]=&#39;.$aValues;

Ive read examples, but I find it messy:

    $url = &#39;http://www.example.com?aParam[]=value1&amp;aParam[]=value2&amp;aParam[]=value3&#39;;





Passing arrays as url parameter

For example, I want to join a prefix path to resource paths like /js/foo.js.

I want the resulting path to be relative to the root of the server.  In the above example if the prefix was &quot;media&quot; I would want the result to be /media/js/foo.js.

os.path.join does this really well, but how it joins paths is OS dependent.  In this case I know I am targeting the web, not the local file system.

Is there a best alternative when you are working with paths you know will be used in URLs?  Will os.path.join work well enough?  Should I just roll my own?

I can&#39;t understand why Java&#39;s `HttpURLConnection` does not follow an HTTP redirect from an HTTP to an HTTPS URL. I use the following code to get the page at https://httpstat.us/:

    import java.net.URL;
    import java.net.HttpURLConnection;
    import java.io.InputStream;

    public class Tester {

        public static void main(String argv[]) throws Exception{
            InputStream is = null;

            try {
                String httpUrl = &quot;http://httpstat.us/301&quot;;
                URL resourceUrl = new URL(httpUrl);
                HttpURLConnection conn = (HttpURLConnection)resourceUrl.openConnection();
                conn.setConnectTimeout(15000);
                conn.setReadTimeout(15000);
                conn.connect();
                is = conn.getInputStream();
                System.out.println(&quot;Original URL: &quot;+httpUrl);
                System.out.println(&quot;Connected to: &quot;+conn.getURL());
                System.out.println(&quot;HTTP response code received: &quot;+conn.getResponseCode());
                System.out.println(&quot;HTTP response message received: &quot;+conn.getResponseMessage());
           } finally {
                if (is != null) is.close();
            }
        }
    }

The output of this program is:

&lt;pre&gt;
Original URL: http://httpstat.us/301
Connected to: http://httpstat.us/301
HTTP response code received: 301
HTTP response message received: Moved Permanently
&lt;/pre&gt;

A request to http://httpstat.us/301 returns the following (shortened) response (which seems absolutely right!):

    HTTP/1.1 301 Moved Permanently
    Cache-Control: private
    Content-Length: 21
    Content-Type: text/plain; charset=utf-8
    Location: https://httpstat.us


Unfortunately, Java&#39;s `HttpURLConnection` does not follow the redirect!

Note that if you change the original URL to HTTPS (https://httpstat.us/301), Java _will_ follow the redirect as expected!?

Can PHP make a redirect call after executing a function?  I am creating a function on the completion of which I want it to redirect to a file located in the same root folder.  Can it be done?

    if (...) {
        // I am using echo here.
    } else if ($_SESSION[&#39;qnum&#39;] &gt; 10) { 
        session_destroy();
        echo &quot;Some error occured.&quot;;
        // Redirect to &quot;user.php&quot;.
    }

PHP page redirect

I have a page that lists all of the projects that has sortable headers and pagination.

    path:
    /projects?order=asc&amp;page=3&amp;sort=code

I choose to edit one of the projects

    path:
    projects/436/edit


When I click save on that page, it calls the projects controller / update method.  After I update the code I want to redirect to the path that I was on before I clicked edit a specific project. In other words, I want to be on the same page with the same sorting.

I saw link_to(:back) and thought that :back may work in redirect_to(:back), but that&#39;s a no go. 

    puts YAML::dump(:back) 
    yields the following:
    :back 

Any ideas on How I could get this to work. It seems like a problem that would be easily solved, but I&#39;m new to RoR.
