How does jquery obtain the radio value?

Use jquery to obtain the radio value. The most important thing is to know how to use the jquery selector. in a form, we usually need to obtain the selected radio.

So you need to add checked for filtering, such as the following radio items:

1.Jquery gets the radio Value

2.Jquery obtains the checkbox Value

3.Jquery obtains the select Value

To obtain a radio value, you can use the following methods:

1. 1. $ ('input [name = "testradio"]: checked'). val ();

2. 1. $ ('input: radio: checked'). val ();

3. 1. $ ('input [@ name = "testradio"] [checked] ');

4. 1. $ ('input [name = "testradio"] '). filter (': checked ');

It's almost complete. If we want to traverse all radio whose name is testradio, the Code is as follows: 1. $ ('input [name = "testradio"] '). each (function ()

{Alert (this. value );});

If you want to obtain a specific radio value, such as the Second radio value, write

1. $ ('input [name = "testradio"]: eq (1) '). val ()
