大家对ajax邮箱、用户名验证掌握多少呢？本文主要介绍了ajax邮箱、用户名唯一性验证实例代码,需要的朋友可以参考下，希望能帮助到大家。
废话不多说了，直接给大家贴代码了，具体代码如下所示：
<script type="text/javascript">
$(function () {
$("#txtemail").blur(function () {
$.ajax({
type: "post",
url: "reg.ashx?email=" + $.trim($("#txtemail").val()) + "&d=" + (+new date()),
success: function (data) {
var vcount = parseint(data);
if (vcount == 0) {
alert("邮箱可以使用");
}
else {
alert("邮箱已经被占用");
}
}
});
});
$("#checkpwd").blur(function () {
return checkpwd();
});
});
function checkpwd()
{
var bcheck = true;
if ($.trim($("#pwd").val()) != $.trim($("#checkpwd").val()))
{
alert("两次密码输入不一致");
bcheck = false;
}
return bcheck;
}
</script>
reg.ashx代码：
using system;
using system.collections.generic;
using system.linq;
using system.web;
namespace webt1.ti.html2
{
/// <summary>
/// reg 的摘要说明
/// </summary>
public class reg : ihttphandler
{
public void processrequest(httpcontext context)
{
if (context.request["email"] != null)
{
string stremail = context.request["email"];
list<usermodel> lstuser = dataservice.getuserlist();
var v = lstuser.where(p => p.email == stremail);
int icount = 0;
if (v.count() > 0)
{
icount = 1;
}
context.response.contenttype = "text/plain";
context.response.write(icount.tostring());
}
}
public bool isreusable
{
get
{
return false;
}
}
}
public class dataservice
{
/// <summary>
/// 模拟已注册用户数据
/// </summary>
public static list<usermodel> getuserlist()
{
var list = new list<usermodel>();
list.add(new usermodel() { email = "t1@demo.com" });
list.add(new usermodel() { email = "t2@demo.com" });
list.add(new usermodel() { email = "t3@demo.com" });
list.add(new usermodel() { email = "t4@demo.com" });
list.add(new usermodel() { email = "t5@demo.com" });
return list;
}
}
public class usermodel
{
public string email { get; set; }
}
}
