这是对应的js
function myChack() {

document.getElementById(‘phone’).innerHTML=”;

 var userPhone=document.getElementById('phone').value;
 var pass=document.getElementById('pass').value;
 var password=document.getElementById('password').value;
 var text_code=document.getElementById('text_code').value;
 var flag=false;//定义一个Boolean类型，接受Ajax的success方法的返回值，因为他们不是同一个函数
    $.ajax({
            url : "/check/code.action",
            type : "post",
            data : {"phoneCode":text_code,"userPhone":userPhone},
            async:false,
