var Url2 = this.invite_code;

//var oInput = document.createElement("input");

var oInput = document.getElementById("inviteCode");

//oInput.value = Url2;

// document.body.appendChild(oInput);

oInput.select();// 选择对象

//document.execCommand("Cut","false",null);// 执行浏览器剪切命令

document.execCommand("Copy");// 执行浏览器复制命令

//oInput.className = "oInput";
