Thje jquery for onclick event doesn't work. The requirement is when i click on any hyperlink in the visualforce page, the alert message shld popup.


My Code:
<apex:page standardController="Core_Benefit__kav"  id="corebenefitpageid" applyBodyTag="false"  sidebar="false" showHeader="true" >
   
    <script>
    j$ = jQuery.noConflict();
    j$(document).ready(function() {
        j$('.openInPopup a').click(function(event) {
            alert( "Handler for .click() called." );
            event.preventDefault();
            window.open(j$(this).attr('href'));
        });
    });   
</script>
    <apex:includeScript value="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"/>
    
   
        <knowledge:articleRendererToolBar articleId="{! $CurrentPage.parameters.id}" id="toolbarid" canVote="true" showChatter="true"/><br/><br/>
        <apex:pageBlock mode="maindetail" id="pageblockid" >
