Checkbox Checkboxes jQuery HOWTO Learning
Checkboxes support in jQuery are one consistent FAQ item that I see asked about (and have asked about myself quite a few times)
Here is a quick DL on the subject.. Taken from the style found in "Learning jQuery" getting an DOM object reference is as easy as the following line of JS code.
var chkIsIntelPerson = $("#chkIsIntelPerson").get(0);
You can also bind a jQuery click event that will not mess with the toggle of the object
The $txtSecurityRoles is a style of sytax from Learning jQuery that I like and represents a jQuery object where as the chkIsIntelPerson is just a normal HTML DOM object.
I hope this helps.
