jQuery .each()索引?

问题描述:

我正在使用

$('#list option').each(function(){
//do stuff
});

循环遍历列表中的选项。
我想知道如何获得当前循环的索引?

to loop over the options in a list. I am wondering how I could get the index of the current loop?

因为我不想让var i = 0;
和循环内部有i ++;

as I dont want to have to have var i = 0; and inside the loop have i++;

$('#list option').each(function(index){
  //do stuff
  alert(index);
});

提醒索引:)
