This should work:

`$(&#39;.myClass, .myOtherClass&#39;).removeClass(&#39;theclass&#39;);`

You must add the multiple selectors all in the first argument to $(), otherwise you are giving jQuery a context in which to search, which is not what you want.

It&#39;s the same as you would do in CSS.

Have you tried this?

    $(&#39;.myClass, .myOtherClass&#39;).removeClass(&#39;theclass&#39;);



I use `$(&#39;.myClass.myOtherClass&#39;).removeClass(&#39;theclass&#39;);`

    // Due to this Code ): Syntax problem.    
    $(&#39;.myClass&#39;, &#39;.myOtherClass&#39;).removeClass(&#39;theclass&#39;); 

According to jQuery documentation:
https://api.jquery.com/multiple-selector/

When can select multiple classes in this way:

    jQuery(“selector1, selector2, selectorN”) // double Commas. // IS valid.
    jQuery(&#39;selector1, selector2, selectorN&#39;) // single Commas. // Is valid.
   
by enclosing all the selectors in a single &#39;...&#39; &#39; or double commas, &quot;...&quot;

So in your case the correct way to call multiple classes is:

    $(&#39;.myClass&#39;, &#39;.myOtherClass&#39;).removeClass(&#39;theclass&#39;); // your Code // Invalid.
    $(&#39;.myClass , .myOtherClass&#39;).removeClass(&#39;theclass&#39;);  // Correct Code // Is valid.



Is there a way that you can get a collection of all of the Models in your Rails app?

Basically, can I do the likes of: -

    Models.each do |model|
      puts model.class.name
    end

I have data in a MySQL database. I am sending the user a URL to get their data out as a CSV file.

I have the e-mailing of the link, MySQL query, etc. covered.

How can I, when they click the link, have a pop-up to download a CVS with the record from MySQL? 

I have all the information to get the record already. I just don&#39;t see how to have PHP create the CSV file and let them download a file with a .csv extension.

I’ve had a good look and can’t seem to find out how to select all elements matching certain classes in one jQuery selector statement such as this:

    $(&#39;.myClass&#39;, &#39;.myOtherClass&#39;).removeClass(&#39;theclass&#39;);

Any ideas on how to achieve this? The only other option is to do

    $(&#39;.myClass&#39;).removeClass(&#39;theclass&#39;);
    $(&#39;.myOtherClass&#39;).removeClass(&#39;theclass&#39;);

But I’m doing this with quite a few classes, so it requires much code.

I have about 7 Javascript files now (thanks to various jQuery plugins) and 4-5 CSS files.  I&#39;m curious as to what&#39;s the best practice for dealing with these including where in the document they should be loaded?  YSlow tells me that Javascript files should be--where possible--included at the end.  The end of the body?  It mentions that the delimeter seems to be whether they write content. All my Javascript files are functions and jQuery code (all done when ready()) so that should be OK.

So should I include one CSS and one Javascript file and have those include the rest?  Should I concatenate all my files into one?  Should I put Javascript my &lt;script src=&quot;&quot;&gt; tags at the very end of my document?

**Edit:** FWIW yes this is PHP.

How do we paste an image from clipboard into a custom rich text editor using javascript? (ctrl+c and ctrl+v or a snapshot).

Has anyone used Ajax&#39;s rich text editor? Does pasting an image from clipboard to Ajax RTE work?

Please do share your thoughts!

Thanks!

I want to use jQuery inside a firefox extension,
I imported the library in the xul file like this:

    &lt;script type=&quot;application/x-javascript&quot; src=&quot;chrome://myExtension/content/jquery.js&quot;&gt; &lt;/script&gt;

but the $() function is not recognized in the xul file neither do the jQuery().

I googled about the problem and found some solutions but no one did work with me:
http://gluei.com/blog/view/using-jquery-inside-your-firefox-extension
http://forums.mozillazine.org/viewtopic.php?f=19&amp;t=989465

I&#39;ve also tried to pass the &#39;content.document&#39; object(which refrences the &#39;document&#39; object) as the context parameter to the jQuery function like this:

    $(&#39;img&#39;,content.document);

but still not working,
does any one came across this problem before?

Where can I find reference code that implements a HTTP Basic Authentication client in pure JavaScript, suitable for AJAX?

Extra points for code, or pointers to code, that can be used independent of JS toolkits like YUI. No points for Java, Flash/Flex, PHP frameworks, etc.

Can someone suggest a way to compare the values of **two dates** greater than, less than, and not in the past using JavaScript? The values will be coming from text boxes.

If I set a CSS value on a specific element using:

    $(&#39;#element&#39;).css(&#39;background-color&#39;, &#39;#ccc&#39;);

I want to be able to unset that element-specific value and use the cascaded value, along the lines of:

    $(&#39;#element&#39;).css(&#39;background-color&#39;, null);

But that syntax doesn&#39;t seem to work – is this possible using another syntax?

**Edit:** The value isn&#39;t inherited from the parent element – the original values comes from an element-level selector. Sorry for any confusion!

I&#39;m working on some JQuery to hide/show some content when I click a link. I can create something like:

    &lt;a href=&quot;#&quot; onclick=&quot;jquery_stuff&quot; /&gt;

But if I click that link while I&#39;m scrolled down on a page, it will jump back up to the top of the page.

If I do something like:

    &lt;a href=&quot;&quot; onclick=&quot;jquery_stuff&quot; /&gt;

The page will reload, which rids the page of all the changes that javascript has made.

Something like this:

    &lt;a onclick=&quot;jquery_stuff&quot; /&gt;

Will give me the desired effect, but it no longer shows up as a link. Is there some way to specify an empty anchor so I can assign a javascript handler to the `onclick` event, without changing anything on the page or moving the scrollbar?

I have a select control, and in a javascript variable I have a text string.

Using jQuery I want to set the selected element of the select control to be the item with the text description I have (as opposed to the value, which I don&#39;t have).

I know setting it by value is pretty trivial. e.g.

    $(&quot;#my-select&quot;).val(myVal);

But I&#39;m a bit stumped on doing it via the text description. I guess there must be a way of getting the value out from the text description, but my brain is too Friday afternoon-ed to be able to work it out.

To select a child node in jQuery one can use children() but also find(). 

For example:

`$(this).children(&#39;.foo&#39;);`

gives the same result as:

`$(this).find(&#39;.foo&#39;);`

Now, which option is fastest or preferred and why?

Consider the following HTML. If I have a JSON reference to the &amp;lt;button&amp;gt; element, how can I get a reference to the outer &amp;lt;tr&amp;gt; element in both cases

	&lt;table id=&quot;my-table&quot;&gt;
		&lt;tr&gt;
			&lt;td&gt;
				&lt;button&gt;Foo&lt;/button&gt;
			&lt;/td&gt;
			&lt;td&gt;
				&lt;div&gt;
					&lt;button&gt;Bar&lt;/button&gt;
				&lt;/div&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
	&lt;/table&gt;
	
	&lt;script type=&quot;text/js&quot;&gt;
		$(&#39;#table button&#39;).click(function(){
			//$(this).parent().parent() will work for the first row
			//$(this).parent().parent().parent() will work for the second row
			//is there a selector or some magic json one liner that will climb
			//the DOM tree until it hits a TR, or do I have to code this myself
			//each time?			
			//$(this).????
		});
	&lt;/script&gt;

I know I could special case each condition, but I&#39;m more interested &quot;however deep you happen to be, climb the tree until you find element X&quot;	style solution.  Something like this, but more jQuery like/less-verbose

	var climb = function(node, str_rule){
		if($(node).is(str_rule)){
			return node;
		}
		else if($(node).is(&#39;body&#39;)){
			return false;
		}
		else{
			return climb(node.parentNode, str_rule);
		}
	};	
	
I know about the parent(expr) method, but from what I&#39;ve seen is allows you filter parents one level up and NOT climb the tree until you find expr (I&#39;d love code example proving me wrong)
