jQuery 生成随机字符

//获取长度为len的随机字母
function zimu(len){
    len = len || 1;
    var $chars = ‘ABCDEFGHIJKLMNOPQRSTUVWXYZ‘;
    var maxPos = $chars.length;
    var pwd = ‘‘;
    for (i = 0; i < len; i++) {
        pwd += $chars.charAt(Math.floor(Math.random() * maxPos));
    }

//引用
$("#Editor").val(mingzi(5));  //生成5个字母

//获取随机邮箱后续
function youxiang(){
	var Arr = ["@qq.com","@163.com","@sina.cn"];
	var n = Math.floor(Math.random()*Arr.length + 1)-1;
	//alert(Arr[n]);
	return Arr[n];
};
