In the previous article /article/83504.htm, user verification was implemented using javascript, but the password was not verified. This time, this function was added and used javascript and jquery respectively. accomplish.

1. Key code implemented using jquery’s ajax

The implementation is as follows

/*jquery实现
$(document).ready(function(){
  $("#account").blur(function(event) {
    $.ajax({
      type:"GET",
      url:"checkAccount.php?account="+$("#account").val(),
      dataTypes:"text",
      success:function(msg){
        $("#accountStatus").html(msg);
      },
      error:function(jqXHR) {
        alert("账号发生错误！")
      },
    });
  });
 
  $("#password").blur(function(event) {
    $.ajax({
      type:"GET",
      url:"checkPassword.php?",
      dataTypes:"text",
      data:"account="+$("#account").val()+"&password="+$("#password").val(),
      success:function(msg){
        $("#passwordStatus").html(msg);
      },
      error:function(jqXHR) {
        alert("密码查询发生错误！")
      },
    });
  });

2. The key to using javascriptCode

The implementation is as follows

//javascript实现

    var xmlhttp;
    var name = document.getElementById("account").value;
    if (window.XMLHttpRequest)
     xmlhttp=new XMLHttpRequest();
    else
     xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
 
    xmlhttp.open("GET","checkAccount.php?account="+name,true);
    xmlhttp.send();
 
    xmlhttp.onreadystatechange=function(){
     if (xmlhttp.readyState==4 && xmlhttp.status==200)
      document.getElementById("accountStatus").innerHTML=xmlhttp.responseText;
    }
  }
 
  function checkPassword(){
    var xmlhttp;
    var name = document.getElementById("account").value;
    var pw = document.getElementById("password").value;
    if (window.XMLHttpRequest)
     xmlhttp=new XMLHttpRequest();
    else
     xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
 
    xmlhttp.open("GET","checkPassword.php?account="+name+"&password="+pw,true);
    xmlhttp.send();
 
    xmlhttp.onreadystatechange=function(){
     if (xmlhttp.readyState==4 && xmlhttp.status==200)
      document.getElementById("passwordStatus").innerHTML=xmlhttp.responseText;
    }
