遍历数组以启用复选框 [英] Loop through an Array to enable checkboxes

问题描述

我有一组复选框和一个数组，其中包含应选择其复选框的索引.我正在尝试遍历数组及其中的每个索引.我制作了一个示例jsFiddle，让大家了解我正在尝试做的事情.如果这使事情变得更容易，我也有JQuery库. http://jsfiddle.net/7EetA/1/

I'm have a set of checkboxes and an array that contains the index of which checkboxes should be selected. I'm trying to loop through the array and for each index in it. I made a sample jsFiddle to give you guys an idea of what I'm trying to do. I have the JQuery library also if that makes things easier. http://jsfiddle.net/7EetA/1/

推荐答案

尝试一下:

var arrx=new Array();
arrx[0]=4;       
arrx[1]=5;
arrx[2]=3;
arrx[3]=1;
for (var i = 0; i < arrx.length; i++) {
    document.getElementsByName('cal')[arrx[i]].checked = true;
}
​

不需要jQuery！ jsFiddle示例
