问题描述
嗨
我创建了一个列表项id的数组,我想知道如何循环遍历数组并获取索引使用Jquery的数组,因为我只想更新数组列表中所选id的类
Hi
I have created an array of the id's of the list item and i would like to know how would i be able to loop through the array and get the index of the array using Jquery as i would like to only update the class of the selected ids which are in the array list
localStorage.selectableList = ["1", "2", "3", "4", "5", "6", "7", "8", "9"]"
var list = JSON.parse(localStorage.selectableList);
这就是我的方式创建了我的数组
That is how i have created my array
推荐答案
你可以这样做
You can do this like
// Your array of ids
var arr = ["1", "2", "3", "4", "5", "6", "7", "8", "9"]
// Loop through the array
.each (arr, function (i,val){
// 从数组项添加类到相应的ID
.each(arr, function (i, val) { // Add class to the respective ids from array items
(' #' + val).addClass(' active');
});
('#' + val).addClass('active'); });
