You can use the Logical NOT `!` operator:

    if (!$(this).parent().next().is(&#39;ul&#39;)){

Or equivalently (see comments below):

    if (! ($(this).parent().next().is(&#39;ul&#39;))){

For more information, see the [Logical Operators][1] section of the MDN docs.


  [1]: https://developer.mozilla.org/en/JavaScript/Reference/Operators/Logical_Operators

Try negation operator `!` before `$(this)`:

    if (!$(this).parent().next().is(&#39;ul&#39;)){

What is a pythonic way of making list of arbitrary length containing evenly spaced numbers (not just whole integers) between given bounds? For instance:

    my_func(0,5,10) # ( lower_bound , upper_bound , length )
    # [ 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5 ] 
Note the `Range()` function only deals with integers. And this:

    def my_func(low,up,leng):
        list = []
        step = (up - low) / float(leng)
        for i in range(leng):
            list.append(low)
            low = low + step
        return list
seems too complicated. Any ideas?

I&#39;m developing a PhoneGap application and I&#39;d like to be able to debug it in Chrome rather than on the phone.  However, I do the initialization of my code in an onDeviceReady() function that is triggered when PhoneGap fires the &quot;deviceready&quot; event.  Since Chrome doesn&#39;t fire this event, my code isn&#39;t ever initialized.

Here&#39;s a stripped down version of my code:

    var dashboard = {};
    
    $(document).ready(function() {
        document.addEventListener(&quot;deviceready&quot;, dashboard.onDeviceReady, false);
    }); 
    
    dashboard.onDeviceReady = function() {
        alert(&quot;hello!&quot;); //this is never fired in Chrome
    };

I&#39;ve tried using the [StopGap][1] code, which basically just does the following:

    var e = document.createEvent(&#39;Events&#39;); 
    e.initEvent(&quot;deviceready&quot;);
    document.dispatchEvent(e);

But when I run that code in the Chrome javascript console, the &quot;hello&quot; alert still doesn&#39;t trigger.  What am I doing wrong?  Or does chrome just not support firing &quot;custom&quot; events like deviceready?

I have a div with contenteditable set and I am capturing keypress using jquery to call preventDefault() when the enter key is pressed. Similar to  [this question](https://stackoverflow.com/questions/2920150/insert-text-at-cursor-in-a-content-editable-div) which inserts text at the cursor, I would like to directly insert html, for brevity we&#39;ll say its a br tag. Using the answer to the question above actually works in IE as it uses the range.pasteHTML method, but in other browsers the br tag  would appear as plain text and not html. How could I modify the answer to insert html and not text ?

I have a handler attached to an event and I would like it to execute only if it is triggered by a human, and not by a trigger() method. How do I tell the difference?

For example,

    $(&#39;.checkbox&#39;).change(function(e){
      if (e.isHuman())
      {
        alert (&#39;human&#39;);
      }
    });

    $(&#39;.checkbox&#39;).trigger(&#39;change&#39;); //doesn&#39;t alert

Check if event is triggered by a human

I have been reading that if you want to convert from JavaScript dates to C# dates you should use `getTime()` and then add that result to a C# `DateTime`.

Suppose I have this JavaScript time:

    Date {Tue Jul 12 2011 16:00:00 GMT-0700 (Pacific Daylight Time)}

It renders to `1310522400000` milliseconds


    var a = new DateTime(1970, 01, 01).AddMilliseconds(1310522400000);

    // result
    7/13/2011 2:00:00 AM

So this is wrong. I am not sure what I need to do.

I&#39;ve done some jQuery in the past, but I am completely stuck on this. I know about the pros and cons of using synchronous ajax  calls, but here it will be required. 

The remote page is loaded (controlled with firebug), but no return is shown.

**What should I do different to make my function to return properly?**

            success : function(data) {
          		remote = data;

        });
    	
    	return remote;
    
    }

jQuery: Performing synchronous AJAX requests

I&#39;m using jQuery to make an AJAX request. I want to perform different actions whether or not the HTTP status code is a 400 error or a 500 error. How can I achieve this?

    $.ajax({
        type: &#39;POST&#39;,
        url: &#39;/controller/action&#39;,
        data: $form.serialize(),
        success: function(data){
            alert(&#39;horray! 200 status code!&#39;);
        },
        error: function(data){
            //get the status code
            if (code == 400) {
                alert(&#39;400 status code! user error&#39;);
            }
            if (code == 500) {
                alert(&#39;500 status code! server error&#39;);
            }
        },
    });

@GeorgeCummins mentioned that it &quot;seemed odd&quot; to work with the response body. This is the first time that I&#39;ve attempted doing this sort of thing. Is my approach not a best-practice?

jQuery Ui Dialog Buttons, How to add class?

I have been using &quot;Accelerated C++&quot; to learn C++ over the summer, and there&#39;s a concept which I don&#39;t seem to understand properly.

Why is

    int x;
    if (cin &gt;&gt; x){}

equivalent to

    cin &gt;&gt; x;
    if (cin){}

By looking at the code, it seems to me that we&#39;re using cin as a variable. But, I thought it was a function. Why can we use cin in this way when it is x that has whatever value we input into our keyboard?

if (cin &gt;&gt; x) - Why can you use that condition?

Are variables declared and assigned in an &quot;if&quot; statement visible only within that &quot;if&quot; block or within the whole function? 

Am I doing this right in the following code? (seems to work, but declaring &quot;var structure&quot; multiple times seems awkward) any cleaner solutions?

        function actionPane(state) {
		if(state === &quot;ed&quot;) {
			var structure = {
				&quot;element&quot; : &quot;div&quot;,
				&quot;attr&quot; : {
					&quot;class&quot; : &quot;actionPane&quot;
				},
				&quot;contains&quot; : [{
					&quot;element&quot; : &quot;a&quot;,
					&quot;attr&quot; : {
						&quot;title&quot; : &quot;edit&quot;,
						&quot;href&quot; : &quot;#&quot;,
						&quot;class&quot; : &quot;edit&quot;
					},
					&quot;contains&quot; : &quot;&quot;
				}, {
					&quot;element&quot; : &quot;a&quot;,
					&quot;attr&quot; : {
						&quot;title&quot; : &quot;delete&quot;,
						&quot;href&quot; : &quot;#&quot;,
						&quot;class&quot; : &quot;delete&quot;
					},
					&quot;contains&quot; : &quot;&quot;
				}]
			}
		} else {
			var structure = {
				&quot;element&quot; : &quot;div&quot;,
				&quot;attr&quot; : {
					&quot;class&quot; : &quot;actionPane&quot;

				&quot;contains&quot; : [{

						&quot;href&quot; : &quot;#&quot;,
						&quot;class&quot; : &quot;save&quot;
					},
					&quot;contains&quot; : &quot;&quot;
				}, {
					&quot;element&quot; : &quot;a&quot;,
					&quot;attr&quot; : {
						&quot;title&quot; : &quot;cancel&quot;,
						&quot;href&quot; : &quot;#&quot;,

		return structure;

javascript variable scope in the IF statement

I know how to use both for loops and if statements on separate lines, such as:

    &gt;&gt;&gt; a = [2,3,4,5,6,7,8,9,0]
    ... xyz = [0,12,4,6,242,7,9]
    ... for x in xyz:
    ...     if x in a:
    ...         print(x)
    0,4,6,7,9


And I know I can use a list comprehension to combine these when the statements are simple, such as:

    print([x for x in xyz if x in a])

But what I can&#39;t find is a good example anywhere (to copy and learn from) demonstrating a complex set of commands (not just &quot;print x&quot;) that occur following a combination of a for loop and some if statements. Something that I would expect looks like:

    for x in xyz if x not in a:
        print(x...)

Is this just not the way python is supposed to work?


Pythonic way to combine for-loop and if-statement

I have been searching everywhere for an explanation. Here&#39;s a real example taken from the apt-fast.sh script:

    if [ ! -x /usr/bin/axel ]
    then echo &quot;axel is not installed, perform this?(y/n)&quot;
        read ops
        case $ops in
         y) if apt-get install axel -y --force-yes
               then echo &quot;axel installed&quot;
            else echo &quot;unable to install the axel. you are using sudo?&quot; ; exit
            fi ;;
         n) echo &quot;not possible usage apt-fast&quot; ; exit ;;
        esac
    fi

What&#39;s the use of `&quot;fi ;;&quot;` in the middle of the `if` block?


Bash - what&#39;s the use of &quot;fi ;;&quot;?

So I want to do something like follows:

    {% if age &gt; 18 %}
        {% with patient as p %}
    {% else %}
        {% with patient.parent as p %}
        ...
    {% endwith %}
    {% endif %}

But Django is telling me that I need another {% endwith %} tag.  Is there any way to rearrange the withs to make this work, or is the syntactic analyzer purposefully carefree in regards to this sort of thing?

Maybe I&#39;m going about this the wrong way.  Is there some sort of best practice when it comes to something like this?

Django {% with %} tags within {% if %} {% else %} tags?

I have a database with a large number of words but i want to select only those records where the character length is equal to a given number (in example case 3):

    $query = (&quot;SELECT * FROM $db WHERE conditions AND length = 3&quot;);

But this does not work... can someone show me the correct query?

querying WHERE condition to character length?

For some reason I can&#39;t remember how to do this - I believe there was a way to set a variable in Python, if a condition was true? What I mean is this:

     value = &#39;Test&#39; if 1 == 1

Where it would hopefully set *value* to &#39;Test&#39; if the condition (1 == 1) is true. And with that, I was going to test for multiple conditions to set different variables, like this:

     value = (&#39;test&#39; if 1 == 1, &#39;testtwo&#39; if 2 == 2)

And so on for just a few conditions. Is this possible?

Python Conditional Variable Setting

I&#39;ve seen both of these two for statements:

    for(i=0;i&lt;10;i++) 
    
    for(i=0;i!=10;i++)

I know they all stop when i reaches `10` , but it seems better to use the second one (I heard).
What is the different?I also want to know when use iterator to access member of a vector, what is the difference between iterator condition `&lt; vec.end()`and `!= vec.end()`



In a &quot;for&quot; statement, should I use `!=` or `&lt;`?

and if yes, what is the syntax?
My goal is to prepend an &#39;s&#39; to the word &#39;comment&#39; when there is more than one. in an jQuery.ejs template in a JMVC app. The following breaks. I can&#39;t find any docs for conditionals...

    &lt;%=commentsNumber%&gt; comment&lt;% if (commentsNumber &gt; 1) { %&gt; s &lt;% } %&gt;

Can I use conditional statements with EJS templates (in JMVC)?

Does C# have a *not* `Conditional` (`!Conditional`, `NotConditional`, `Conditional(!)`) attribute?


----------


i know C# has a [`Conditional` attribute][1]:

    [Conditional(&quot;ShowDebugString&quot;)]
    public static void ShowDebugString(string s)
    {
       ...
    }

which is equivalent&lt;sup&gt;1&lt;/sup&gt; to:

    public static void ShowDebugString(string s)
    {
    #if ShowDebugString
       ...
    #endif
    }

But in this case i want the *inverse* behavior (you have to specifically *opt out*):


    public static void ShowDebugString(string s)
    {
    #if !RemoveSDS
       ...
    #endif
    }

Which leads me to try:


    [!Conditional(&quot;RemoveSDS&quot;)]
    public static void ShowDebugString(string s)
    {
       ...
    }

which doesn&#39;t compile. And:


    [Conditional(&quot;!RemoveSDS&quot;)]
    public static void ShowDebugString(string s)
    {
       ...
    }

which doesn&#39;t compile. And:


    [NotConditional(&quot;RemoveSDS&quot;)]
    public static void ShowDebugString(string s)
    {
       ...
    }

which doesn&#39;t compile because it&#39;s only wishful thinking.

&lt;sup&gt;1&lt;/sup&gt; [Not true, but true enough. Don&#39;t make me bring back the Nitpicker&#39;s Corner.][2] &lt;sup&gt;[&#128343;][3]&lt;/sup&gt;
