Jquery - 找到同一类的所有元素，隐藏没有特定rel的div

Question

My HTML:

<div class="mydiv" rel="1">test one</div>
<div class="mydiv" rel="2">test two</div>
<div class="mydiv" rel="3">test three</div>
<div class="mydiv" rel="2">test three</div>

My goal is to use jQuery to hide all div elements that DO NOT have a rel of, say, 1.

The rel value will be dynamically generated. So I would like to hide any div.mydiv where the rel != 1.

Any help is appreciated.

Answer 1

隐藏除了一个之外具有rel值的所有div都是这样简单的：

$(".myDiv[rel!=1]").hide();

Answer 2

$('.mydiv').filter(function() {
    return $(this).attr('rel') != 1;
}).hide();

Answer 3

$(".myDiv[rel!=1]").hide(); is proper answer to your question. OR you can do this way as well

$('div.mydiv').not('div[rel="1"]').hide();
