我可以使用jQuery从元素中删除最后添加的类吗 [英] Can I remove just the last added class from an element with jQuery

问题描述

伙计们，这个问题几乎要问自己了……但是，为了更加清楚:

Hey guys, the question pretty much asks itself... however, for more clarity:

我有一个名为"chuckPalahniuk"的元素，它有名为"choke"，"fightclub"和"haunted"的类.

I have an element called "chuckPalahniuk" and it has classes named "choke", "fightclub" and "haunted".

当我单击"chuckPalahniuk"元素时，如何将其删除"，先将其困扰"，然后将其"fightclub"删除，将其单击，将其第三次删除，将其删除?

How could I get it so when I click on the "chuckPalahniuk" element, it removes "haunted" first, then "fightclub" on the second click and "choke" on the third?

也:请注意，类名是动态添加的.

also: be aware that the class names are dynamically added.

干杯. peeeps！

Cheers. peeeps!

psy.example:

psy.example:

$('#chuckPalahniuk').click(function() {
  $(this).removeLastClassAdded(); //except this function doesn't exist...
});

推荐答案

只需将添加的每个类c.push('yourclass')，然后是$(this).removeClass(c.pop());

just save in an array variable c every class you add c.push('yourclass'), then $(this).removeClass(c.pop());
