js字符串的拼接 用逗号隔开

var arr = [{"name":"hhh"},{"name":"dddd"}]//用jsfunction getTextByJs() {var str = "";for (var i = 0; i < arr.length; i++) {str += arr[i].name+ ",";}//去掉最后一个逗号(如果不需要去掉，就不用写)if (str.length > 0) {str = str.substr(0, str.length - 1);}return str;}//输出结果: hhh,dddd//用jqueryfunction getTextByJquery() {var str = "";arr.each(function () {str += $(this).name.val() + ",";});//去掉最后一个逗号(如果不需要去掉，就不用写)if (str.length > 0) {str = str.substr(0,str.length - 1);}return str;}//输出结果: hhh,dddd
