    $(&#39;.someclass&#39;).length

You could also use:

    $(&#39;.someclass&#39;).size()

which is functionally equivalent, but [the former is preferred][1].  In fact, the latter is now [deprecated][2] and shouldn&#39;t be used in any new development.

  [2]: http://api.jquery.com/category/deprecated/

    var count_elements = $(&#39;.class&#39;).length;

From: http://api.jquery.com/size/

&gt; The .size() method is functionally
&gt; equivalent to the .length property;
&gt; however, the .length property is
&gt; preferred because it does not have the
&gt; overhead of a function call.



Please see:

http://api.jquery.com/length/



Yes, there is.

    $(&#39;.MyClass&#39;).size()

I believe this works:

    $(&quot;.MyClass&quot;).length 

try this:

    var count_element = $(&#39;.element&#39;).length

    $(&#39;.class&#39;).length
This one does not work for me. I&#39;d rather use this:

    $(&#39;.class&#39;).children().length
I don&#39;t really know the reason why, but the second one works only for me. Somewhy, either size doesn&#39;t work.

The best way would be to use [.each()][1]
    
    var num = 0;

    $(&#39;.className&#39;).each(function(){
        num++;
    });

use the `.size()` method or `.length` attribute

Could someone please explain to me the idea of **artifacts** in the build process?

I have the workspace directory where I check out the code to compile and run my ant scripts etc. At the end, in my case, I get a jar file that&#39;s ready to install. Is that considered to be the artifact?

Where should I tell my build script to put the jar file? In the workspace directory? My jar file gets a unique filename depending on variables like `BUILD_ID` and such, how can I tell Jenkins which jar file to pick?


EDIT:
Okay, so i tried doing something like this:

![enter image description here][1]

The path does not exist yet in my workspace, because the build script is supposed to create it, and of course, the `.jar` and `.properties` files are not there because they haven&#39;t been generated yet. Why does it give me an error then? Seems like I&#39;m missing something.

Also, does Jenkins delete the artifacts after each build (not the archived artifacts, I know I can tell it to delete those)? Otherwise it will clog the hard drive pretty quickly.

Archive the artifacts in Jenkins

I would like to have an input field that users can enter custom text value or choose from drop down. A regular `&lt;select&gt;` only offers drop down options.
 
**How can I make a `&lt;select&gt;` accept custom value?** For instance: Ford?

    &lt;select&gt;
      &lt;option value=&quot;volvo&quot;&gt;Volvo&lt;/option&gt;
      &lt;option value=&quot;saab&quot;&gt;Saab&lt;/option&gt;
      &lt;option value=&quot;mercedes&quot;&gt;Mercedes&lt;/option&gt;
      &lt;option value=&quot;audi&quot;&gt;Audi&lt;/option&gt;
    &lt;/select&gt;


HTML select form with option to enter custom value

Is there a way to count how many elements on the page with a particular class?


Count elements with jQuery

<p>Is there a way to count how many elements on the page with a particular class?</p>


I want to create something like a recorder whichs tracks all actions of a user. For that, i need to identify elements the user interacts with, so that i can refer to these elements in a later session.

Spoken in pseudo-code, i want to be able to do something like the following

Sample HTML (could be of any complexity):

    &lt;html&gt;
    &lt;body&gt;
      &lt;div class=&quot;example&quot;&gt;
        &lt;p&gt;foo&lt;/p&gt;
        &lt;span&gt;&lt;a href=&quot;bar&quot;&gt;bar&lt;/a&gt;&lt;/span&gt;
      &lt;/div&gt;
    &lt;/body&gt;
    &lt;/html&gt;
      
User clicks on something, like the link. Now i need to identify the clicked element and save its location in the DOM tree for later usage:

    (any element).onclick(function() {
      uniqueSelector = $(this).getUniqueSelector();
    })

Now, uniqueSelector should be something like (i don&#39;t mind if it is xpath or css selector style):

    html &gt; body &gt; div.example &gt; span &gt; a

This would provide the possibility to save that selector string and use it at a later time, to replay the actions the user made.

How is that possible?

&lt;h1&gt;Update&lt;/h1&gt;

Get unique selector of element in Jquery

This is driving me crazy - why doesn&#39;t my code work?

    &lt;a id=&quot;send-thoughts&quot; href=&quot;&quot;&gt;Click&lt;/a&gt;
    &lt;textarea id=&quot;#message&quot;&gt;&lt;/textarea&gt;

                jQuery(&quot;a#send-thoughts&quot;).click(function() {
                    var thought = jQuery(&quot;textarea#message&quot;).val();
                    alert(thought);
                });

alerts undefined.

Getting Textarea Value with jQuery

I can&#39;t find the right selector for:

    &lt;input maxlength=&quot;6&quot; size=&quot;6&quot; id=&quot;colorpickerField1&quot; name=&quot;sitebg&quot; value=&quot;#EEEEEE&quot; type=&quot;text&quot;&gt;

I want to change the value to = 000000. I need the selector to find the &quot;name&quot; not the id of the text input.

Shouldn&#39;t this work?:

    $(&quot;text.sitebg&quot;).val(&quot;000000&quot;);

The presented solution does not work, what&#39;s the problem with this?

    $.getJSON(&quot;http://www.mysitehere.org/wp-content/themes/ctr-theme/update_genform.php&quot;,function(data) {
        $(&quot;#form1&quot;).append(data.sitebg);
    	$(&#39;input.sitebg&#39;).val(&#39;000000&#39;);
    });

The JSON data is working correctly; the idea is to later pass the JSON values into the form input text values. But is not working :(

jQuery change input text value

I&#39;d like (just to test some functions, after I&#39;ll avoid this behaviour) to load the page called by submit on a new tab : is it possible?

submit a form in a new tab

I have a `.submit()` event set up for form submission.  I also have multiple forms on the page, but just one here for this example.  I&#39;d like to know which submit button was clicked without applying a `.click()` event to each one.

Here&#39;s the setup:

    &lt;html&gt;
    &lt;head&gt;
      &lt;title&gt;jQuery research: forms&lt;/title&gt;
      &lt;script type=&#39;text/javascript&#39; src=&#39;../jquery-1.5.2.min.js&#39;&gt;&lt;/script&gt;
      &lt;script type=&#39;text/javascript&#39; language=&#39;javascript&#39;&gt;
          $(document).ready(function(){
              $(&#39;form[name=&quot;testform&quot;]&#39;).submit( function(event){ process_form_submission(event); } );
          });
          function process_form_submission( event ) {
              event.preventDefault();
              //var target = $(event.target);
              var me = event.currentTarget;
              var data = me.data.value;
              var which_button = &#39;?&#39;;       // &lt;-- this is what I want to know
              alert( &#39;data: &#39; + data + &#39;, button: &#39; + which_button );
          }
      &lt;/script&gt;
    &lt;/head&gt;
    &lt;body&gt;
    &lt;h2&gt;Here&#39;s my form:&lt;/h2&gt;
    &lt;form action=&#39;nothing&#39; method=&#39;post&#39; name=&#39;testform&#39;&gt;
      &lt;input type=&#39;hidden&#39; name=&#39;data&#39; value=&#39;blahdatayadda&#39; /&gt;
      &lt;input type=&#39;submit&#39; name=&#39;name1&#39; value=&#39;value1&#39; /&gt;
      &lt;input type=&#39;submit&#39; name=&#39;name2&#39; value=&#39;value2&#39; /&gt;
    &lt;/form&gt;
    &lt;/body&gt;
    &lt;/html&gt;

    



&lt;a href=&quot;http://jsfiddle.net/fKppt/&quot;&gt;Live example on jsfiddle&lt;/a&gt;

Besides applying a .click() event on each button, is there a way to determine which submit button was clicked?
