Describe is a function in the [Jasmine][1] testing framework.  It simply describes the suite of test cases enumerated by the &quot;it&quot; functions.

Also used in the [mochajs][2] framework.

`Describe` is not part of Javascript, it is a function defined in the library you used (namely Jasmine)

According to the [Jasmine Documentation][1]

&gt; The `describe` function is for grouping related specs, typically each test file has one at the top level. The string parameter is for naming the collection of specs, and will be concatenated with specs to make a spec&#39;s full name.

The &quot;describe&quot; block is used to group tests together in jest. 
Have a look at the following link. Go to the `scoping` section, You shall understand why and how it is been used.

I was writing some code today and got a weird compile error, which seems to be caused by initializing member variables in a different order than they were declared.

Example:

    class Test {
        int a;
        int b;
    
    public:
        Test() : b(1), a(2) {
        }
    };
    
    int main() {
        Test test;
        return 0;
    }

Then if I compile it with `-Werror -Wall`:

    $ g++ -Werror -Wall test.cpp
    test.cpp: In constructor ‘Test::Test()’:
    test.cpp:3:9: error: ‘Test::b’ will be initialized after [-Werror=reorder]
    test.cpp:2:9: error:   ‘int Test::a’ [-Werror=reorder]
    test.cpp:6:5: error:   when initialized here [-Werror=reorder]
    cc1plus: all warnings being treated as errors

I realize that `-Wall` is explicitly asking GCC to go over-the-top with warnings, but I assume there&#39;s a reason for all of them. So, how could the order of initializing member variables matter?

Why should I initialize member variables in the order they&#39;re declared in?

Is there a good technique to make a resizable split pane in HTML?

May it be done using CSS / jQuery / JavaScript or is there a good JavaScript library that have been used?

(An example of a split pane is the favorites bar in [Internet&amp;nbsp;Explorer][1] which you may have docked to the left of your main browser window.)

So I am a newbie in javascript and i had been going through some one else&#39;s code and I found this..  

    describe(&#39;deviceready&#39;, function() {
        it(&#39;should report that it fired&#39;, function() {
            spyOn(app, &#39;report&#39;);
            app.deviceready();
            expect(app.report).toHaveBeenCalledWith(&#39;deviceready&#39;);
        });
    });


What I don&#39;t understand is: 
What exactly does the `describe` keyword do?

info:  
 -  Its a **phonegap** application  
 -  We are using the *spine.js* and *jQuery* libraries

I develop plugins for WordPress. It uses some jquery in the user side (themes) as a jquery plugin.
The problem is, when there is an javascript error with other plugins made by other autors, my plugin&#39;s javascript fails to execute.

And the worst thing is people consider that there is a serious fault with my plugin even though it works 100% fine with error handling conditional statements. But it is actually due to some other javascript syntax errors of some other WP plugin/theme authors.

Is there a way to continue execute my plugin JS ignoring other JS errors. Or can i have suggestions to handle this problem ??

I&#39;m asking this just for the sake of shaving a few bytes. 

I know I can use `+x` (unary plus) instead of `Number(x)`. Is there a difference between those and `parseFloat`?

First, I&#39;m not interested in doing this professionally. I am a web developer, a coworker of mine recently left for Spotify and said he will be working mostly in JavaScript for the Spotify Desktop app. He said it uses &quot;Chrome frame&quot; and everything inside is done like a web app (HTML/JS/CSS).

As a web developer who never built anything for Desktop, this is great news. If I can use the technologies I already know and implement them inside some sort of a &quot;frame&quot; and still be able to build a windows or better yet cross platform app.

I know I didn&#39;t mention anything about the database, but even a simple hello world desktop app with web technologies would be great to get going.

So how does one go about this? Exactly what do I need/need to know?

This may be a dumb question for web guys. But I am a little confused over this. Now, I have an application where I am using a couple of Javascript files to perform different tasks. Now, I am using Javascript [bundler][1] to combine and minify all the files. So, at runtime there will be only one app.min.js file. Now, [Requirejs][2] is used to load modules or files at runtime. So, the question is if I already have all things in one file, then do I need requirejs? Or what is a use case scenario where I can use requirejs and/or bundler?

Please let me know if any further details are needed.

I was reading a good book on JavaScript. 

It started with: 
&gt; Boolean type take only two literal values: true and false. These are distinct from numeric values, so true is not equal to 1, and false is not equal to 0.

However, I observed following:

    if(1==true)
      document.write(&quot;oh!!! that&#39;s true&quot;);  //**this is displayed**

I know, that every type in JavaScript has a Boolean equivalent. 

But then, what&#39;s the truth? 


Is true == 1 and false == 0 in JavaScript?

I&#39;ve read that [ mobile Safari has a 300ms delay on click events][1] from the time the link/button is clicked to the time the event fires. The reason for the delay is to wait to see if the user intends to double-click, but from a UX perspective waiting 300ms is often undesirable.

[One solution][2] to eliminate this 300ms delay is to use jQuery Mobile &quot;tap&quot; handling. Unfortunately I&#39;m not familiar with this framework and don&#39;t want to load some big framework if all I need is a line or two of code applying `touchend` in the right way.



Like many sites, my site has many click events like this: 

    $(&quot;button.submitBtn&quot;).on(&#39;click&#39;, function (e) {   
      $.ajaxSubmit({... //ajax form submisssion
    });

    $(&quot;a.ajax&quot;).on(&#39;click&#39;, function (e) {   
      $.ajax({... //ajax page loading
    });

    $(&quot;button.modal&quot;).on(&#39;click&#39;, function (e) {   
          //show/hide modal dialog
    });
    

and what I&#39;d like to do is to get rid of the 300ms delay on **ALL** those click events using a single code snippet like this:

    $(&quot;a, button&quot;).on(&#39;tap&#39;, function (e) {
     $(this).trigger(&#39;click&#39;);
     e.preventDefault();
    });

Is that a bad/good idea?

I&#39;ve got a seemingly simple problem with no apparent _(by reading the Angular JS docs)_ solution.

I have got an Angular JS directive that does some calculations based on other DOM elements&#39; height to define the height of a container in the DOM.

Something similar to this is going on inside the directive:

    return function(scope, element, attrs) {
        $(&#39;.main&#39;).height( $(&#39;.site-header&#39;).height() -  $(&#39;.site-footer&#39;).height() );
    }

The issue is that when the directive runs, `$(&#39;site-header&#39;)` cannot be found, returning an empty array instead of the jQuery wrapped DOM element I need.

Is there a callback that I can use within my directive that only runs after the DOM has been loaded and I can access other DOM elements via the normal jQuery selector style queries?

How can I run a directive after the dom has finished rendering?

I&#39;m attempting to use jQuery to capture a submit event and then send the form elements formatted as JSON to a PHP page.
I&#39;m having issues capturing the submit though, I started with a `.click()` event but moved to the `.submit()` one instead.

I now have the following trimmed down code.

HTML

    &lt;form method=&quot;POST&quot; id=&quot;login_form&quot;&gt;
        &lt;label&gt;Username:&lt;/label&gt;
        &lt;input type=&quot;text&quot; name=&quot;username&quot; id=&quot;username&quot;/&gt;
        &lt;label&gt;Password:&lt;/label&gt;
        &lt;input type=&quot;password&quot; name=&quot;password&quot; id=&quot;password&quot;/&gt;
        &lt;input type=&quot;submit&quot; value=&quot;Submit&quot; name=&quot;submit&quot; class=&quot;submit&quot; id=&quot;submit&quot; /&gt;
    &lt;/form&gt;

Javascript

    $(&#39;#login_form&#39;).submit(function() {
        var data = $(&quot;#login_form :input&quot;).serializeArray();
    	alert(&#39;Handler for .submit() called.&#39;);
    });

I might have an error in a `.js` document in a theme I have purchase:

    $(&#39;.tagcloud a&#39;).wrap(&#39;&lt;span class=&quot;st_tag&quot; /&gt;&#39;);

I am trying to solve it but I am not a programmer so I don&#39;t know how.

TypeError: $ is not a function WordPress

I am new to phonegap. I have prepared one sample application. My application has 2 pages, the first page has one button, when clicked the second page will open. It is working fine using the following


             function callAnothePage()
             {
                window.location = &quot;test.html&quot;;
             }


The second page has one button, when clicked I want to exit from the application. I used the following


           function exitFromApp()
           {
                navigator.app.exitApp();
           }


`test.html` code,

    &lt;!DOCTYPE html&gt;
    &lt;html&gt;
    
    &lt;head&gt;
        &lt;script type=&quot;text/javascript&quot; charset=&quot;utf-8&quot; src=&quot;cordova-2.0.0.js&quot;&gt;&lt;/script&gt;
        &lt;script type=&quot;text/javascript&quot; charset=&quot;utf-8&quot;&gt;  
            function onLoad()
            {
                console.log(&quot;device reday !!!!&quot;)
                document.addEventListener(&quot;deviceready&quot;, onDeviceReady, true);
            }
            function exitFromApp()
            {
                console.log(&quot;in button&quot;);
                navigator.app.exitApp();
            }
        &lt;/script&gt;
    &lt;/head&gt;
    
    &lt;body onload=&quot;onLoad();&quot;&gt;
        &lt;h4&gt;&lt;center&gt;Login Page&lt;/center&gt;&lt;/h4&gt;
    
        &lt;input type=&quot;submit&quot; onclick=&quot;exitFromApp()&quot; value=&quot;exit&quot;/&gt;
    
    &lt;/body&gt;
    &lt;/html&gt;

But it is not working.

Exit from app when click button in android phonegap?

App Dies On Startup (connection to the server was unsuccessful) 

I have an Android application that I&#39;m writing using PhoneGap BUILD. The app was working fine earlier, but now it seems I am getting this error after refining my app (some UI changes only)

1) When I start the app I (usually) get: 

**Application Error - The connection to the server was unsuccessful. 
(file:///android_asset/www/index.html)** 

Sorry if this is duplication of any question. I have seen some similar questions here, but i couldn&#39;t find a perfect answer or solution. As in my case it was working fine until my last changes.

I am making a phonegap application with jquery. I am confused whether I should wrap my entire code inside JQuery&#39;s `$(document).ready()` like

    $(document).ready(function(){
        //mycode
    });

or inside the deviceready event of phonegap like

    document.addEventListener(&quot;deviceready&quot;, function(){
        //mycode
    });

I am currently using `document.ready` but I think I may encounter problems if I try to access some Phonegap API methods inside `document.ready`.

Which is the best event to wrap my code in, document.ready or deviceready?

I&#39;m working on a Phonegap-based iOS app, which is already done for Android. The following lines are working fine for Android but not for iOS. Why?

    var d = new Date(&quot;2015-12-31 00:00:00&quot;);
    console.log(d.getDate() + &#39;. &#39; + d.getMonth() + &#39; &#39; + d.getFullYear();

Result for Android:

    31.11 2015

Result on iOS:

    NaN. NaN NaN

Where is the difference coming from?
