获取所选单选按钮的值

Question

I have defined a set of radio buttons in HTML in a form as follows. The name of my form is "MyForm". When Female is selected, I want the value of a variable to be equal to "Female".

<fieldset data-role="controlgroup" data-type="horizontal" id="gender" name="gender">
                    <legend>Gender :</legend>
  <input type="radio" name="radio-choice-1" id="radio-choice-1" value="choice-1" checked="checked" />
                        <label for="radio-choice-1">Male</label>

 <input type="radio" name="radio-choice-1" id="radio-choice-2" value="choice-2"/>
                        <label for="radio-choice-2">Female</label>
                </fieldset>

I tried as var

genderValue = $('input[name=gender]:checked', '#MyForm').val()

But this is not working. What is the correct way?

Answer 1

you can store the values( female , ... ), in value attribute of the inputs, based on your markup you can try the following:

$('input[name="radio-choice-1"]').change(function(){
   var genderValue = $(this).next('label').text()
})

but I'd suggest this one:

$('input[name="radio-choice-1"]').change(function(){
   var genderValue = this.value
})

 $('input[name="radio-choice-1"]').change(function(){ var genderValue = this.value }) 

Answer 2

Your issue has been solved as below:

HTML:

<form id="MyForm" name="MyForm" method="post">
  <fieldset>
    <legend>
      Gender
    </legend>
    <div id="panel">
      <input type="radio" name="radio-choice" id="radio-choice-1" value="choice-1" />
      <label for="radio-choice-1">
        Male
      </label>
      <input type="radio" name="radio-choice" id="radio-choice-2" value="choice-2" />
      <label for="radio-choice-2">
        Female
      </label>
    </div>
    <div id="result">
    </div>
  </fieldset>
</form>

jQuery:

$(function() {
    $('input[name="radio-choice"]').change(function() {
        var genderValue = $(this).next('label').text();
        $("#result").html("<p> You have selected " + genderValue + ".");
    })
});

Answer 3

This might helpful to someone, Here is another way to retrieve selected radio button value

var gender = $('input[name="radio-choice-1"]:checked').val();

Setting id to radio buttons is optional here.

Happy coding!....
