Answer 3

There is a better way of checking radios and checkbox; you have to pass an array of values to the val method instead of a raw value

Note: If you simply pass the value by itself (without being inside an array), that will result in all values of "mygroup" being set to the value.

$("input[name=mygroup]").val([5]);

Here is the jQuery doc that explains how it works: http://api.jquery.com/val/#val-value

And .val([...]) also works with form elements like <input type="checkbox">, <input type="radio">, and <option>s inside of a <select>.

The inputs and the options having a value that matches one of the elements of the array will be checked or selected, while those having a value that don't match one of the elements of the array will be unchecked or unselected

Or you can just write value attribute to it:

$(':radio[value=<yourvalue>]').attr('checked',true);

This works for me.
