Adding jQuery doesn't seem to do anything

Question

To add the jquery, plus my own file (main.js), I pasted this piece of code in my local.xml:

    <block type="core/text" name="google.cdn.jquery">
        <action method="setText">
            <text><![CDATA[<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script><script>window.jQuery||document.write('<script src="/path/to/your/jquery.js">\x3c/script>');</script><script>jQuery.noConflict();</script>]]></text>
        </action>
    </block>

    <action method="addItem">
        <type>skin_js</type>
        <name>js/main.js</name>
    </action>

Seems alright, but when I use this function in my main.js file, it doesn't do anything. Not even a console error:

$j('.block-title').click(function(){
    alert();
});

I know this will probably be marked as a duplicate, but all the answers I've found don't seem to work. I have tried changing the classname, but that also did not work.

UPDATE

So I found out jQuery does work, with this:

var $j=jQuery.noConflict();

But there is still a problem.

$j(document).click();

Works fine, but when I call a class, like this:

 $j('.footer').click()

It does nothing. I checked the classname alot, and even changed a few times to test. Didn't work. Is it possible, that jQuery 1.10.2 uses another form of calling classes?

LAST UPDATE:

Seems I had forgotten to place the .click function within the $j(document).ready() function... stupid me

Answer 1

As you mentioned that you should use $j because of the noConflict() I'm pretty you can fix your issue by replacing:

jQuery.noConflict();

With:

$j = jQuery.noConflict();

Edit: the problem was that the OP forgot to use $j(document).ready in its main js code.
