Search and replace REL attribute with jQuery

I want to search links and replace their rel attributes if the rel attribute currently equal attachement.

The code I have so far is:

开发者_运维问答$("href").each(function(index) {
    $(this).attr('rel', 'group');
});

If you're trying to test the rel value against something (let's say "attachment"), all you have to do is something like this:

$('a[rel="attachment"]').attr('rel','group');

This says that for all <a> elements with rel="attachment", set rel to "group".

On the other hand, if what you mean to change is all elements with an href attribute, you'll use something like

$('[href][rel="attachment"]').attr('rel','group');

$('a').each(function() {
  $(this).attr('rel', 'group')
});

Not sure what you're trying to test the value of 'rel' against.

no such selector as href

try:

$("a").each(function() {
    $(this).attr('rel', 'group');
});

Do you mean equals "attachment"?

$("a").each(function(index) {
    // href is `this.href`
    if(this.rel == 'attachment') 
        $(this).attr('rel', 'group');  
});
