jQuery attribute selectors: How to query for an attribute with a custom namespace
jQuery does not support custom namespaces directly, but you can find the divs you are looking for by using filter function.
// find all divs that have custom:attr$('div').filter(function() { return $(this).attr('custom:attr'); }).each(function() { // matched a div with custom::attr $(this).html('I was found.');});
This works in some conditions:
$("div[custom\\:attr]")
However, for a more advanced method, see this XML Namespace jQuery plug-in
the syntax for matching by attribute is:
$("div[customattr=bla]") matches div customattr="bla"
$("[customattr]") matches all tags with the attribute "customattr"
with namespace attributes like 'custom:attr' its not working
Here you can find a good overview.
