Can't set element ID in JavaScript, it's always undefined
- by Dylaan Alith
Hi,
I want to have a function that generates ID's on the fly for a given jquery object, if it doesn't have one already. These ID's should then be used in future requests.
I came up with the code below, but it doesn't work. The ID's are never set. The commented out alert statement below always return undefined.
I always pass code like $(this) or $(options.el) as a parameter to substitute 'el'. Initially, the elements do not have explicitly ID set in HTML.
Any help would be appreciated, here's the code:
getElementId: function(el)
{
if(undefined == el.attr('id'))
{
el.attr('id',"anim-"+Math.random().toString().substr(2));
}
// alert(el.attr('id'));
return el.attr('id');
},
