Setting the screen position when visiting previous page with jQuery
The scenario This problem came while I was working on a client’s website. Take this scenario. I have a listing page (similar to a listing page from www.trademe.co.nz or www.ascent.co.nz ).

JQuery 1.6+ attr and prop issue
I used the following code to make sure all radio buttons where unchecked and the current one was set correctly. This worked well before jQuery 1.6. $(document).ready(function() { SetUniqueRadioButton = function(current, id) { jQuery("input[type=radio]").each(function() { $(this).attr("checked", false); }); current.checked = true; }; }); Since jQuery 1.6, this code did not work and after doing some [...]

Limiting the number of text in textarea using JQuery

JQuery Event Delegation
Came across a awesome way of handling events using JQuery’s event delegation methods. I have a list of A tags grouped in a table, and each A tag will call a method and pass a ID based on a value in the same column of that A tag. jQuery(“#tableId”).click(function(event) { var $target = jQuery(event.target), target [...]
