Set selected radio from radio group with a value

Question

Why am I struggling with this?

I have a value: 5

How do I check the radio button of group \"mygroup\" with the value of 5?

$(\"input[name=myg         


        

Answer 1

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 , , and s inside of a .

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
