javascript - jQuery - 如何选择变量的后缀并在数组中找到它的匹配项

Question

我有一系列的选择:

var options = ["foo_A", "foo_B", "foo_C", "foo_D"];

...当用户点击以下元素之一时...

<div id="bar_A"> </div>
<div id="bar_B"> </div>
<div id="bar_C"> </div>
<div id="bar_D"> </div>

...它设置以下变量:

var currentBar = $(this).attr('id');

...然后我想搜索选项数组并找到其后缀与 currentBar 的后缀匹配的项目，如下所示:

 $.each(options, function(i,v){
 if (v's suffix matches the currentBar's suffix){

 //function to do something

}

Answer 1

$.each(options, function(i,v){
    if (options[i].split("_")[1] == currentBar.split("_")[1]){

   //function to do something

}
