Class names can&#39;t have spaces in them. What you have there is two classes:

    &lt;div class=&quot;panel current&quot;&gt;

This div has two classes: panel and current. That&#39;s easily selected:

    $(&quot;div.panel.current&quot;)...

That means select all divs that have class panel *and* class current.



    $(&#39;div&#39;).filter(function() {
        return this.className == &#39;panel current&#39;;
    });

OR

    $(&quot;div[class=&#39;panel current&#39;]&quot;);

Use this if you need to match an element with an exact match of class names (including spaces)

The other posters are right, the DiV you posted has two class names: &#39;panel&#39; and &#39;current&#39;;
If you want to select them both, use `$(&#39;.panel.current&#39;)`.

This will also include elements like:

    &lt;div class=&quot;foo panel bar current&quot;&gt;&lt;/div&gt;



`panel current` is not a class name, actually it is two class names. You could use the following selector:

    $(&#39;.panel.current&#39;)

The `div` has two `class` names:
 

 - `panel`
 - `current`

You can use `$(&quot;div.panel&quot;)` or `$(&quot;div.current&quot;)` to select it.

Sorry, dumb question number 2 today.  Is it possible to determine if a file is contained within the App Bundle?  I can access files no problem, i.e.,

    NSString *pathAndFileName = [[NSBundle mainBundle] pathForResource:fileName ofType:@&quot;plist&quot;];

But can&#39;t figure out how to check if the file exists there in the first place.

How can you determine if a file exists within the app bundle?

If a PHP script is run as a cron script, the includes often fail if relative paths are used. For example, if you have

    require_once(&#39;foo.php&#39;);
the file foo.php will be found when run on the command line, but not when run from a cron script.

A typical workaround for this is to first chdir to the working directory, or use absolute paths. I would like to know, however, what is different between cron and shell that causes this behavior. Why does it fail when using relative paths in a cron script?

How can I format numbers using a comma separator every three digits using jQuery?

For example:

&lt;!-- language: none --&gt;

    ╔═══════════╦═════════════╗
    ║   Input   ║   Output    ║
    ╠═══════════╬═════════════╣
    ║       298 ║         298 ║
    ║      2984 ║       2,984 ║

I am trying to understand the jquery plugin syntax, because I want to merge two plugins into
one. The blinker that also needs to be able to stop de interval or run a number of times.

Anyway,
is this syntax the same as

    jQuery.fn.extend({
    	everyTime: function(interval, label, fn, times) {
    		return this.each(function() {
    			jQuery.timer.add(this, interval, label, fn, times);
    		});
    	},
    	oneTime: function(interval, label, fn) {
    		return this.each(function() {
    			jQuery.timer.add(this, interval, label, fn, 1);
    		});
    	},

**this**

    $.fn.blink = function(options)
    	{
because it looks like the first(without =) is a way to set multiple methods at once.
Is this right?
Also while I am here
What would be the reason to add the elements and some logic to the jquery object?

    jQuery.extend({

(this is from the timer plugin)

I have an action class that generates a PDF. The `contentType` is set appropriately.

    public class MyAction extends ActionSupport 
    {
       public String execute() {
        ...
        ...
        File report = signedPdfExporter.generateReport(xyzData, props);

        inputStream = new FileInputStream(report);
        contentDisposition = &quot;attachment=\&quot;&quot; + report.getName() + &quot;\&quot;&quot;;
        contentType = &quot;application/pdf&quot;;
        return SUCCESS;
       }
    }

I call this `action`  through an Ajax call. I don&#39;t know the way to deliver this stream to browser. I tried a few things but nothing worked.

    $.ajax({
        type: &quot;POST&quot;,
        url: url,
        data: wireIdList,
        cache: false,
        success: function(response)
        {
            alert(&#39;got response&#39;);
            window.open(response);
        },
        error: function (XMLHttpRequest, textStatus, errorThrown) 
        {
            alert(&#39;Error occurred while opening fax template&#39; 
                  + getAjaxErrorString(textStatus, errorThrown));
        }
    });

The above gives the error:

&gt; Your browser sent a request that this server could not understand.

I have element E and I&#39;m appending some elements to it. All of a sudden, I find out that the next element should be the first child of E. What&#39;s the trick, how to do it? Method unshift doesn&#39;t work because E is an object, not array. 

Long way would be to iterate trough E&#39;s children and to move&#39;em key++, but I&#39;m sure that there is a prettier way.

I want to know if a class can inherit from a class and an interface. 
The example code below doesn&#39;t work but I think it conveys what I want to do.
The reason that I want to do this is because at my company we make USB, serial, Ethernet, etc device. I am trying to develop a generic component/interface that I can use to write programs for all our devices that will help keep the common things (like connecting, disconnecting, getting firmware) the same for all of our applications.

To add to this question:  If GenericDevice is in different project, can I put the IOurDevices interface in that project then then make the USBDevice class implement the interface if I add a reference to the first project? Because would like to just reference one project and then implement different interfaces depending on what the device is.

    class GenericDevice
    {
       private string _connectionState;
       public connectionState
       {
          get{return _connectionState; }
          set{ _connectionState = value;}
       }
    }
    
    interface IOurDevices
    {
       void connectToDevice();
       void DisconnectDevice();
       void GetFirmwareVersion();
    }
    
    class USBDevice : IOurDevices : GenericDevice
    {
       //here I would define the methods in the interface
       //like this...
       void connectToDevice()
       {
           connectionState = &quot;connected&quot;;
       }
    }
    
    //so that in my main program I can do this...
    
    class myProgram
    {
       main()
       {
          USBDevice myUSB = new USBDevice();
          myUSB.ConnectToDevice;
       }
    }

What is the difference between `Class.forName()` and `Class.forName().newInstance()`?

I do not understand the significant difference (I have read something about them!). Could you please help me?

What is the difference between &quot;Class.forName()&quot; and &quot;Class.forName().newInstance()&quot;?

Please could someone experienced in PHP help out with the following. Somewhere in my code, I have a call to a public static method inside a non-instantiated class:

    $result = myClassName::myFunctionName();

However, I would like to have many such classes and determine the correct class name on the fly according to the user&#39;s language. In other words, I have:

    $language = &#39;EN&#39;;

... and I need to do something like:

    $result = myClassName_EN::myFunctionName();

I know I could pass the language as a parameter to the function and deal with it inside just one common class but for various reasons, I would prefer a different solution.

Does this make any sense, anyone? Thanks.





Dynamic static method call in PHP?

In psuedo code, this is what I want.

    var selector = $(this).cssSelectorAsString(); // Made up method...
    // selector is now something like: &quot;html&gt;body&gt;ul&gt;li&gt;img[3]&quot;
    var element = $(selector);

The reason is that I need to pass this off to an external environment, where a string is my only way to exchange data.  This external environment then needs to send back a result, along with what element to update.  So I need to be able to serialize a unique CSS selector for every element on the page.

I noticed jquery has a `selector` method, but it does not appear to work in this context.  It only works if the object was created with a selector.  It does not work if the object was created with an HTML node object.

Getting a jQuery selector for an element

I want to get a list of names of checkboxes that are selected in a div with certain id. How would I do that using jQuery?

E.g., for this div I want to get array [&quot;c_n_0&quot;; &quot;c_n_3&quot;] or a string &quot;c_n_0;c_n_3&quot;

    &lt;div id=&quot;checkboxes&quot;&gt;
        &lt;input id=&quot;chkbx_0&quot; type=&quot;checkbox&quot; name=&quot;c_n_0&quot; checked=&quot;checked&quot; /&gt;Option 1
        &lt;input id=&quot;chkbx_1&quot; type=&quot;checkbox&quot; name=&quot;c_n_1&quot; /&gt;Option 2
        &lt;input id=&quot;chkbx_2&quot; type=&quot;checkbox&quot; name=&quot;c_n_2&quot; /&gt;Option 3
        &lt;input id=&quot;chkbx_3&quot; type=&quot;checkbox&quot; name=&quot;c_n_3&quot; checked=&quot;checked&quot; /&gt;Option 4
    &lt;/div&gt;


Get a list of checked checkboxes in a div using jQuery

With:

&lt;!-- language: lang-javascript --&gt;

    if(element.hasClass(&quot;class&quot;))

I can check for one class, but is there an easy way to check whether &quot;element&quot; has any of many classes?

I am using:

&lt;!-- language: lang-javascript --&gt;

    if(element.hasClass(&quot;class&quot;) || element.hasClass(&quot;class&quot;) ... )

Which isn&#39;t too bad, but I am thinking of something like:

&lt;!-- language: lang-javascript --&gt;

    if(element.hasClass(&quot;class&quot;, &quot;class2&quot;)

Which unfortunately doesn&#39;t work.

Is there something like that?

jQuery hasClass() - check for more than one class

For whatever reason I have these classes called `.main_sub1`, `.main_sub2` etc. Never mind why I can&#39;t have `.main .sub`.

Is there a way with jQuery, sort of in the way it is possible to do with attributes, to get the classes containing `main`?
