this question sounds a bit confusing, but here is what i have:
<div id="type2">
<img class="profile-img" src="75.jpg">
</div>
after i click on something it becomes like this:
<div id="type2">
<img class="profile-img" src="75.jpg">
<img class="profile-img" src="76.jpg">
</div>
what i want is to remove the first img
instance if two are present.
basically to become:
<div id="type2">
<img class="profile-img" src="76.jpg">
</div>
i've tryed:
if (item.lenght == 2) {
$('#type2').find('.profile-img:first'开发者_如何学JAVA).remove();
}
but it doesn't seem to work thanks
edit:
thanks all. this answer is what worked for me from shifty:
if ($('#type2').find('.profile-img').size() >= 2) {
$('#type2').find('.profile-img:first').remove();
}
i did misspelled the length
but still didn't want to work :)
The code $('#type2').find('.profile-img:first').remove();
will definitely remove the first element with the class profile-img
in the #type2
selector, so things are broken elsewhere.
Is it just because you've misspelled the length
attribute in item.lenght
?
this should work
if ($('#type2').find('.profile-img').size() >= 2) {
$('#type2').find('.profile-img:first').remove();
}
This should work:
$('.profile-img','#type2').eq(0).remove();
or
$('.profile-img','#type2').first().remove();
or
$('#type2 .profile-img:first').remove();
or
$('.profile-img:first','#type2').remove();
Your way should work fine. I would guess the problem is the typo "lenght":
if (item.length == 2) {
$('#type2').find('.profile-img:first').remove();
}
Assuming of course that item
is defined and has a length of exactly 2.
