Javascript
Dynamically Changing src Attribute of script
I had a situation where I wanted to change the src of a script dynamically before the script runs.
Given the following code, we needed to change src before the script gets executed:
<html> <body> <script language="JavaScript" type="text/javascript" src="..."></script> </body> </html>
So simply (This simply took a couple of hours!) I did this:
<script language="JavaScript" type="text/javascript"> url = .... function staticLoadScript() { document.write('<script language="JavaScript" type="text/javascript" src="', url, '"><\/script>'); } staticLoadScript(); </script>
JQuery Selectors
$("a").click(function() {
alert("Hello world!");
});
In the above code $("a") is a jQuery selector. It selects all 'a' elements. $ itself is an alias for the jQuery "class", therefore $() constructs a new jQuery object. The click() function is a method of the jQuery object. It binds a click event to all selected elements and executes the provided function when the event occurs.
Selecting item can be done down a path, like: $("div > ul a")
If you want to select just one element use #itsID inside single or double quotes:
//With id:
$('#theId')
//With class:
$('.theCssClass')
<input type="button" id ="x" value="Test" />
<input type="button" value="Disable" onclick="$('#x').attr('disabled','disabled')"/>
setInterval
setTimeout() triggers expression only once but setInterval() keeps triggering expression again and again (unless you tell it to stop).
window.setInterval("function()",300); window.setInterval(function showAnn(){/*do something*/ },3000);
