js字符串格式化数组

你可以使用以下方法将一个带逗号的字符串格式化为数组的形式：

function changearray(s){
    var ar = new Array();
    ar = s.split(",");
    return ar;
}

这个方法将输入的字符串通过逗号分隔符分离为多个元素，并将这些元素保存在一个数组中。你可以调用这个函数并传入一个带逗号的字符串作为参数，然后得到一个包含分隔后的元素的数组作为结果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
