js对象封装 Json字符

不废话直接上代码：

function objUserNickName(UserName, NickName)
{
    this.UserName = UserName;
    this.NickName = NickName;
}
objuser1 = new objUserNickName();
objuser1.UserName = TopUserNameNickName[i].dataset.username;
objuser1.NickName = $(TopUserNameNickName[i]).find(\"div\").eq(2).find(\"h3\")[\"0\"].innerText;

 var ary = new Array();

 ary.push(objuser);
return JSON.stringify(ary);
