如何解码Javascript/jQuery [object Object]

Question

我有这个HTML:

<input class="radio" type="radio" name="which_app" value="" id="whichApp1" required>
<label class="left-narrow" for="whichApp1">Program #1</label><br />
<input class="radio" type="radio" name="which_app" value="" id="whichApp2">
<label class="left-narrow" for="whichApp2">Program #2</label>

我有这个脚本:

$( 'input[type=radio][name=which_app]' ).change( function() {
  var label = $("label[for='"+$(this).attr('id')+"']");
  alert( label );
}

我收到此弹出警报:

如何解码[object Object]以获取被点击的标签？(还有其他原因value=""在这个时候不使用,所以我试图只关注它label.谢谢你)

Answer 1

用这个

alert(label.html());

要么

得到文字

alert(label.text());
