Question

I have a radio button that looks like this:

<input class="MCQRadio" id="MCQ" mcq-id="1" name="MCQ" question-id="1" type="radio" value="MCQ" /> MCQ

<><>>

When i click the radiobutton, and several radio buttons have the same class name, how do i retrive the question-id value and mcq-id value from the specific button? Preferably with jQuery.

我已经设立了这样一个点击手:

$(document).ready(function () {

    $( .MCQRadio ).click(function () {

Answer 1

所提供的大多数答复都是正确的。我将作一补充,避免两度进入OM,以找到你的无线电台。

//Store the jQuery object in a variable so that it s only retrieved once
var $myRadio = $( #MCQ );

//Get your attributes
var mcq-id = $myRadio.attr("mcq-id");
var question-id = $myRadio.attr("question-id");

也可附上所有无线电台的点击事件(按班级挑选)和在事件手里挖掘特性:

$( .MCQRadio ).click(function() {
    //Use $(this) to grab the attribute value of the selected element
    var mcq-id = $(this).attr( question-id );
    var question-id = $(this).attr( mcq-id );
});

Answer 2

$( #MCQ ).attr( question-id )
$( #MCQ ).attr( mcq-id )

Answer 3

var mcq-id = $( #MCQ ).attr("mcq-id");
var question-id = $( #MCQ ).attr("question-id");

Answer 4

The other answers already show you how to get the particular attributes. But since you added in your edit that you want to get the attributes from the particular one that was clicked you can try:

$( .MCQRadio ).click(function() {

   $(this).attr( question-id );
   $(this).attr( mcq-id );

});

Answer 5

These will return the values you want.

$( #MCQ ).attr( mcq-id )
$( #MCQ ).attr( question-id )
