jQuery：如何检查输入后是否有标签

Question

How do I check if label tag exist after input tag?

I have this code

$j(document).ready(function () {
    $j('input[type="checkbox"],input[type="radio"]').each(function () {


    });
});

I want to check immediately after input[type:checkbox] and input[tyoe:radio] if there is label tag.

If yes then do nothing, if no then add an empty label tag <label></label>

Anyone know how?

You can use jQuery next() to see if next element is label. You will get length = 0 if there is not label. Once you know if you have label next to input element you can use after() to insert element after the current element.

if(!$j(this).next('label').length)
   $j(this).after('<label></label>');
