jQuery-选择具有相同属性值的多个元素

Question

I am trying to find a jQuery selector that gets every element with a specific attribute value - not necessarily the same attribute , just the same attribute value. For example, what jQuery selector would pick up each of the following?

<h1 name="test"><h1>
<a id="test"></a>
<p data-attribute="test"></p>

All I can think to try is $("*").attr( "*", "test" ) but that does not work.

This is a very odd question. It can be accomplished by looping through the attributes of each dom attribute, but I would recommend instead restructuring your HTML so you can use [data-test=true] , a data-test attribute with the value of true.

 $("*").filter(function() { flag = false; $.each(this.attributes, function(i, attrib){ if (attrib.value == "test") { flag = true; } }); return flag; }).css("background","red"); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <h1 name="test">a<h1> <a id="test">b</a> <p data-attribute="test">c</p> <p>don't highlight</p>
