How do I use jQuery to ignore case when selecting?

问题

I'm currently attempting to disable a link using the following jQuery selector:

$("a[href$=/sites/abcd/sectors]").removeAttr("href");

The problem is that sometimes the href might not always be lower case on the page. When this happens the selector no longer matches.

Does anyone know how to get around this? Can I change the behaviour this once to ignore case?

回答1:

I ran into this myself. I switched the logic a bit to allow me to compare it without case. It requires a little more work, but at least it works.

$('a').each(function(i,n) {
    var href = $(n).attr("href");
    href = href.toLowerCase();
    if (href.endsWith('/sites/abcd/sectors'))
        $(n).removeAttr('href');
});

You would have to figure out your own endsWith logic.

jQuery was built to be extended. You can correct it or add your own type of case-insensitive selector.

You may use function "is" in jQuery. It is not case-sensitive.

   $("a").each(function() {
     if ($(this).is("a[href$=/sites/abcd/sectors]")) {
       $(this).removeAttr('href');
     }
   })

First this is NOT VALID expression since it contains \ ,

If you wish to use any of the meta-characters ( such as !"#$%&'()*+,./:;<=>?@[\]^``{|}~ ) as

a literal part of a name, you must escape the character with two backslashes: \\.

so you must escape the / to \\/

so your expression will be $("a[href$=\\/sites\\/abcd\\/sectors]").removeAttr("href");
