我正在使用MVC进行应用程序。在我看来,我有一个名为EmailId的文本框和一个Submit按钮。如果我输入电子邮件ID并提交按钮,则按钮的标签要更改为验证,并且应清除文本框而不刷新页面。
我的观看页面是
<div class="sign" id="email">
@using (Html.BeginForm("Randa", "BU", FormMethod.Post))
{
<div class="sign1">
<div class="sign2" style="height:267px;width:562px;margin-left:214px" id="cdiv">
@Html.TextBox("EmailId","", new {@placeholder ="Enter the Email id",id="txtemail "})<br /><br />
<input type="submit" name="submit" value="Sign Up" id="btn" onclick="addbutton()" class="addbutton"/>
</div>
</div>
}
</div>
<div class="drnd" id="rnd" style="display:none">
@using (Html.BeginForm("Ra_verify", "BU", FormMethod.Post))
{
<div class="sign1">
<div class="sign2" style="height:267px;width:562px;margin-left:214px" id="cdiv">
@Html.TextBox("Getran", "", new { @placeholder = "Enter the Randam", id = "txtrnd" })<br /><br />
<input type="submit" name="submit" value="Verify" id="btnrnd" class="addbutton" />
</div>
</div>
}
</div>
}
<script type="text/javascript">
var btxt = "Verified";
document.getElementById("#btn").innerHTML = btxt;
</script>
<script type="text/javascript">
function addbutton()
{
($("#email").hide())
$("#rnd").show();
}
</script>
我的控制器代码是
public ActionResult Randa()
{
return View();
}
[HttpPost]
// send the randam No to the Entered mail id . Store the mail id and randam no into tbl_bussiness table;
public ActionResult Randa(string EmailId, string submit)
{
string userId = System.Configuration.ConfigurationManager.AppSettings["UserTypeId"];
int typeid = Convert.ToInt32(userId);
if (ModelState.IsValid)
{
if (submit != null && EmailId != null)
{
EmailManager.SendConfirmationEmail(EmailId);
tbl_BusinessUser b = new tbl_BusinessUser();
b.EmailId = EmailId;
b.RandomNumber = (int)Session["rnd"];
b.UserTypeId = typeid;
b.CreateDTTM = System.DateTime.Now;
db.tbl_BusinessUser.Add(b);
db.SaveChanges();
ViewBag.message = "Please check ur Mail for randam no.Enter random in textbox ";
}
else
{
ModelState.AddModelError("", "Error");
}
}
return View();
}
public ActionResult Ra_verify()
{
return View();
}
[HttpPost]
// check the random no with table random no ,if match redirect to registration create page
public ActionResult Ra_verify(int EmailId, string submit)
{
if (submit != null)
{
// int c = Convert.ToInt32(EmailId);
tbl_BusinessUser b = new tbl_BusinessUser();
var tbra = db.tbl_BusinessUser.Where(x => x.RandomNumber == EmailId).FirstOrDefault();
//var tbram = Convert.ToInt32(tbra);
return RedirectToAction("Create", "BU");
}
return View();
}
任何人都可以帮助我吗? 在此先感谢。

每当我们想要更新网页中的值而不刷新时,我们就必须使用Ajax。
我们必须做以下事情才能使您的网页有效。
由于您在控制器中有两个POST操作,因此请将两个div保留为“rnd”和“email”
以下是带有Ajax选项的示例脚本块,可根据您的请求更新页面,
$('#btn').click(function () {
var urlinfo = '/Home/Randa';
var textboxValue = $('#txtemail').val();
$.ajax({
type: "POST",
data: { value: textboxValue },
url: urlinfo,
success: function (result) {
$('#email').hide();
$('#rnd').show();
},
error: function () {
alert("failed");
}
});
});

首先,您需要使用Ajax.BeginForm
Using Ajax.BeginForm with ASP.NET MVC 3 Razor
在success
函数上,您可以编写以下代码用于明文EmailId和一个Submit按钮。
$("#EmailId").val("");
$("#btn").val("Verify");
如果您打算执行上述操作,则不需要两种表格。
