get associated radio button label text using javascript

<label for="radio1">
        This Radio Button 1 has a label associated with it.</开发者_运维技巧label>
    <input type="radio" name="Radio" id="radio1" />

above code has a label and radio button , the label is associated with radio button using the for attribute.

I would like to get the label text if user selects/checks the associated radio button.

I know this question is months old, and even already has an accepted answer, but every response here uses the prev method. Just wanted to point out that a slightly more robust technique would be using an attribute selector:

$('input:radio').click(function () {
    var txt = $('label[for=' + this.id + ']').text();
    alert(txt);
});

If your using jquery:

$('input[name="Radio"]').click(function(){ alert( $(this).prev('label').text() ) });

check out this example: http://jsfiddle.net/7FzQ9/

$('input#radio1').prev('label[for=radio1]').text();

$("input:radio").click(function() {
  // if the label is before the radio button
  alert( $(this).prev("label").text() );
  // otherwise use
  alert( $("label[for='" + this.id + "']").text() );
});

You can also use:

$("input:radio").click(function() {
   var label_description = this.parentElement.outerText;
   alert( label_description );
} )
