jQuery select by attribute using AND and OR operators

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"]');

jquery jquery-selectors find operators

$('[myc="blue"]').filter('[myid="1"],[myid="2"]');

In general, chaining selectors, like a.foo.bar[attr=value] is some kind of AND selector.

jQuery has extensive documentation about the supported selectors, it's worth a read.

How about writing a filter like below,

$('[myc="blue"]').filter(function () {   return (this.id == '1' || this.id == '3');});

Edit: @Jack Thanks.. totally missed it..

$('[myc="blue"]').filter(function() {   var myId = $(this).attr('myid');      return (myId == '1' || myId == '3');});
