jquery删除div和以前的标签？

Question

These are some input fields which i need to remove, but i am not able to remove the label tag

 <label class="prfx-row-title">Unique Selling Proposition </label>
 <div class="prfx-row-content">
     <input type="text" name="dynamic_usp[0][text]" placeholder="unique selling proposition " value="testing hello world" />
     <span class="remove button">Remove USP</span>
 </div>

$(".remove").live('click', function() {
            $(this).parent().remove();
            $(this).parent().prev('label.prfx-row-title').remove();
        });

Now only the div is remove but not the label?

Anyone?

Answer 1

That's because when removing the div , it is no longer in the DOM, so the label is not a sibling anymore. remove the label first, then the div :

$(".remove").live('click', function() {
     $(this).parent().prev('label.prfx-row-title').remove();
     $(this).parent().remove();
});

Or better :

$(".remove").live('click', function() {
     $(this).parent().prev('label.prfx-row-title').remove()
     .end().remove();
});

Answer 2

You can't remove prev() from something that is no longer there... so the easiest fix is just to rearrange the order...

$(".remove").live('click', function () {
    $(this).parent().prev('label.prfx-row-title').remove();
    $(this).parent().remove();
});

Also, if possible you might want to update the version of jquery you are using and use on() instead of live() . live() has been deprecated since 1.7 and removed since 1.9

You could also consider changing your DOM to something like...

<div class="prfx-row">
    <label class="prfx-row-title">Unique Selling Proposition</label>
    <div class="prfx-row-content">
        <input type="text" name="dynamic_usp[0][text]" placeholder="unique selling proposition " value="testing hello world" /><span class="remove button">Remove USP</span>

    </div>
</div>

and that way you could just do..

$(this).closest("prfx-row").remove();
