if the current uURL is not same as specified then apply jQuery. BUT THIS WONT WORK

<script type="text/javascript">
var myurl = http://example.com/document.html;
var currenturl = window.location
if(myurl 开发者_如何学运维== currenturl) {
    $("<span>url's match</span>").replaceAll("body"); // check replaceWith() examples
}
</script>

Also current URL can be a standard link http://example.com/ or as shown in example.

You need to quote your URL:

var myurl = http://site.com/document.html;

// Should be
var myurl = "http://site.com/document.html";

For best practice, don't omit the ; here:

var currenturl = window.location
//---------------------------^^^^

You are missing quotes on the first line:

var myurl = "http://site.com/document.html";

And it should be != on the third line
