Obtain a set of radio buttonsObject:var obj_payPlatform = $( '#wrap input[name="payMethod"]');

Get the value of the selected button: var val_payPlatform = $('#wrap input[name="payMethod"]: checked ').val();

Example 2:

Use jquery to get the value of radio. The most important thing is to master the use of jquery selector. In a form, we usually want to get the value of the selected radio item, so we need to add checked to filter. For example, there are the following radio items:

1.<input type="radio" name="testradio" value="jquery获取radio的值" />jquery获取radio的值
2.<input type="radio" name="testradio" value="jquery获取checkbox的值" />jquery获取checkbox的值
3.<input type="radio" name="testradio" value="jquery获取select的值" />jquery获取select的值

If you want to get the value of a certain radio There are several methods for the value. The code is given directly:

1,

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

is almost complete. If we want to traverse all radios with the name testradio, the code As follows

$('input[name="testradio"]').each(function(){2.alert(this.value);3.});

If you want to get the value of a specific radio, such as the value of the second radio, write like this

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