jQuery $(document).ready () fires twice

I've been sifting around the web trying to find out whats going on here and I have not been able to get a concrete answer.

I have one $(document).ready on my site that seams to run multiple times regardless of the code that is inside it.

I've read up on the bug reports for jQuery about how the .ready event will fire twice if you have an exception that occurs within your statement. However even when I have the following code it still runs twice:

$(document).ready(function() {
    try{    
        console.log('ready');
        }
    catch(e){
        console.log(e);
    }
});

In the console all I see is "ready" logged twice. Is it possible that another .ready with an exception in it would cause an issue? My understanding was that all .ready tags were independent of each other, but I cannot seem to find where this is coming into play?

Here is the head block for the site:

<head>
<title>${path.title}</title>
<meta name="Description" content="${path.description}" />
<link href="${cssHost}${path.pathCss}" rel="stylesheet" type="text/css" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript" charset="utf-8"><!----></script>
<script src="media/js/fancybox/jquery.fancybox.pack.js" type="text/javascript" ><!-- --></script>
<script src="/media/es/jobsite/js/landing.js" type="text/javascript" ><!-- --></script>
<script src="/media/es/jobsite/js/functions.js" type="text/javascript"><!-- -->    </script>

<script src="/media/es/jobsite/js/queryNormilization.js" type="text/javascript" charset="utf-8"><!----></script>
<script src="${jsHost}/js/jquery/jquery.metadata.js" type="text/javascript" charset="utf-8"><!----></script>

<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.7/jquery.validate.min.js" type="text/javascript" charset="utf-8"><!----></script>
<script src="${jsHost}/js/jquery.i18n.properties-min.js" type="text/javascript" charset="utf-8"><!----></script>

<script type="text/javascript" charset="utf-8">

function updateBannerLink() {
    var s4 = location.hash.substring(1);
    $("#banner").attr('href','http://INTELATRACKING.ORG/?a=12240&amp;c=29258&amp;s4='+s4+'&amp;s5=^');
}

</script>
</head>

Pay no attention to the JSP variables, but as you can see i'm only calling the functions.js file once (which is where the .ready function exists)

The ready event cannot fire twice. What is more than likely happening is you have code that is moving or manipulating the element that the code is contained within which causes the browser to re-execute the script block.

This can be avoided by including script tags in the <head> or before the closing </body> tag and not using $('body').wrapInner();. using $('body').html($('body').html().replace(...)); has the same effect.

It happened to me also, but I realized that the script had been included twice because of a bad merge.

This happened to me when using KendoUI... invoking a popup window would cause the document.ready event to fire multiple times. The easy solution is to set a global flag so that it only runs once:

var pageInitialized = false;
$(function()
{
    if(pageInitialized) return;
    pageInitialized = true;
    // Put your init logic here.
});

It's sort of hack-ish, but it works.

Make sure you don't include JS file twice. That was my case

You might consider to use

window.onload

instead of

$(document).ready
