问题描述
I'm thinking about, if it is possible in jQuery to select elements by named attributes using AND and OR.
Example:
<div myid="1" myc="blue">1</div>
<div myid="2" myc="blue">2</div>
<div myid="3" myc="blue">3</div>
<div myid="4">4</div>
I'd like to select all the elements where myc="blue"
but only those with myid
set to either 1 or 3.
So I tried:
a=$('[myc="blue"] [myid="1"] [myid="3"]');
but it does not work, same here:
a=$('[myc="blue"] && [myid="1"] || [myid="3"]');
Is it possible without writing special filter functions?
解决方案
AND operation
a=$('[myc="blue"][myid="1"][myid="3"]');
OR operation, use commas
a=$('[myc="blue"],[myid="1"],[myid="3"]');
As @Vega commented:
a=$('[myc="blue"][myid="1"],[myc="blue"][myid="3"]');
