How to get checked radio buttons value in jQuery mobile?

问题

I have a set of radio button groups. How can I get which is checked yes or now for each group and add them to array?

Here is what I came up so far:

My jquery code:

<script type="text/javascript">
    $(function () {

        $("#getinfo").click(function () {

            $("input[name*=radio-choice-1]:checked").each(function () {
                 alert($(this).val());
            });

        });   

    });       

</script>

and radio buttons

<fieldset data-role="controlgroup" data-type="horizontal" data-role="fieldcontain">        
<input type="radio" name="radio-choice-1" id="radio-choice-1" value="choice-1" />
<label for="radio-choice-1">Yes</label>
<input type="radio" name="radio-choice-1" id="radio-choice-2" value="choice-2" />
<label for="radio-choice-2">No</label>
</fieldset>

<fieldset data-role="controlgroup" data-type="horizontal" data-role="fieldcontain">        
<input type="radio" name="radio-choice-3" id="radio-choice-3" value="choice-3" />
<label for="radio-choice-3">Yes</label>
<input type="radio" name="radio-choice-3" id="radio-choice-4" value="choice-4" />
<label for="radio-choice-4">No</label>
</fieldset>

<fieldset data-role="controlgroup" data-type="horizontal" data-role="fieldcontain">        
<input type="radio" name="radio-choice-5" id="radio-choice-5" value="choice-5"  />
<label for="radio-choice-5">Yes</label>
<input type="radio" name="radio-choice-5" id="radio-choice-6" value="choice-6" />
<label for="radio-choice-6">No</label>
</fieldset>

<fieldset data-role="controlgroup" data-type="horizontal" data-role="fieldcontain">        
<input type="radio" name="radio-choice-7" id="radio-choice-7" value="choice-7" />
<label for="radio-choice-7">Yes</label>
<input type="radio" name="radio-choice-7" id="radio-choice-8" value="choice-8" />
<label for="radio-choice-8">No</label>
</fieldset>

<a href="#" id="getinfo">getinfo</a>

回答1:

You're looking for the checked radio button with a name containing the text radio-choice-1 - that's only ever going to be one radio button, because it's the full name. I think what you actually wanted is the checked radio buttons with a name containing the text radio-button-, so just remove the 1 from your selector and it should work.

This will do the work. I'm using the below code in my project. Simple and straight forward as given in the jQuery Mobile documentation.

$("input[type='radio']").bind( "change", function(event, ui) {
        console.log($(this).val());
});
