我在我的asp页面中使用仅CSS3 进行了用户注册的模式对话框(弹出窗口): HTML:
<%-- Modal PopUp starts here--%>
<div id="openModal" class="modalDialog">
<div> <a href="#close" title="Close" class="close" onclick="DisableAllPopUpTxt()">X</a>
<table style="width:100%;">
<tr>
<td style="text-align: center; width: 100%;"></td>
</tr>
<tr>
<td style="text-align: center; width: 100%;">
<asp:Label ID="lblErrorMSG2" runat="server" Font-Bold="True" ForeColor="#FF3300" Text="Email ID Already Taken " Visible="False"></asp:Label>
</td>
</tr>
<tr>
<td style="text-align: center; width: 100%;">
<input id="txtCustFName" name="txtCustFName" type="text" required placeholder="Enter Your First Name" style="width: 80%" />
</td>
</td>
</tr>
<tr>
<td style="text-align: center; width: 100%;">
<input id="txtCustLName" name="txtCustLName" type="text" required placeholder="Enter Your Last Name" style="width: 80%" />
</td>
</td>
</tr>
<tr>
<td style="text-align: center; width: 100%;">
<input id="txtCustREmail" name="txtCustREmail" type="email" required placeholder="Enter Valid Email ID" style="width: 80%" />
</td>
</td>
</tr>
<tr>
<td style="text-align: center; width: 100%;">
<input id="txtCustRPwd" name="txtCustRPwd" type="password" required placeholder="Enter Password" style="width: 80%" />
</td>
</td>
</tr>
<tr>
<td style="text-align: center; width: 100%;">
<input id="txtCustRePwd" name="txtCustRePwd" type="password" required placeholder="ReType Password" style="width: 80%" />
</td>
</td>
</tr>
<tr>
<td style="text-align: center; width: 100%;">
<input id="txtCustPh" name="txtCustPh" type="number" size="10" min="10" max="10" required placeholder="Enter Valid Mobile No" style="width: 80%" />
</td>
</td>
</tr>
<tr>
<td class="style1" style="text-align: center; width: 100%;" onclick="btnSignUp()">
<asp:Button ID="btnSingUp" runat="server" onclick="signUp" Text="Login" />
</td>
</tr>
<tr>
<td style="text-align: center; width: 100%;"> </td>
</tr>
</table>
</div>
</div>
<%--Modal PopUp Ends Here--%>
CSS:
.modalDialog {
position: fixed;
font-family: Arial, Helvetica, sans-serif;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: rgba(0,0,0,0.8);
z-index: 99999;
opacity:0;
-webkit-transition: opacity 400ms ease-in;
-moz-transition: opacity 400ms ease-in;
transition: opacity 400ms ease-in;
pointer-events: none;
}
.modalDialog:target {
opacity:1;
pointer-events: auto;
}
.modalDialog > div {
width: 400px;
position: relative;
margin: 10% auto;
padding: 5px 20px 13px 20px;
border-radius: 10px;
background: #fff;
background: -moz-linear-gradient(#fff, #999);
background: -webkit-linear-gradient(#fff, #999);

}
.close {
background: #606061;
color: #FFFFFF;
line-height: 25px;
position: absolute;
right: -12px;
text-align: center;
top: -10px;
width: 24px;
text-decoration: none;
font-weight: bold;
-webkit-border-radius: 12px;
-moz-border-radius: 12px;
border-radius: 12px;
-moz-box-shadow: 1px 1px 3px #000;
-webkit-box-shadow: 1px 1px 3px #000;
box-shadow: 1px 1px 3px #000;}
.close:hover { background: #00d9ff;
}
在我的asp页面中,我遵循用于显示弹出窗口的锚标记:
<a href="#openModal" id="DialogLink" style="color: #FFFFFF; font-weight: bold">Register</a>
现在的问题是:
由于这是注册表单,我希望服务器端验证现有的电子邮件ID。 如果用户输入的电子邮件ID已存在于DB中,我想重新打开上述模式对话框,并显示错误消息,电子邮件ID已存在。
我无法重新打开该对话框。 有没有办法用js做到这一点?

我们可以使用ajax实现这一点....请检查以下示例代码
$("#btnSubmit").live("click",(function(e) {
var emailAddress = $.trim($('#txtEmailAddress').val());
try
{
var reqUrl = "http://mysite/Sample/Sample.aspx?post=true";
var jqXHRresponse;
var request = $.ajax({
url: reqUrl,
type: "POST",
data: {email:emailAddress},
dataType: 'json',
success:function (data, status, jqXHR) {
jqXHRresponse = JSON.parse(jqXHR.responseText);
if(jqXHRresponse.result == 'success')
{
/Do Something/
}
else if(jqXHRresponse.result == 'emailexist')
{
DisplayErrorMessages('Email Already Exist');
}
});
return false; }));
protected override void OnInit(EventArgs e)
{
if (Request.Params["post"] == "true")
{
submitValues(Request.Params["email"]);
}
}
public void submitValues(string email)
{
string returnValue = string.Empty;
//Call DB and send response back
Response.Write("{\"result\":\"" + retrunValue+ "\"}");
Response.End();
}
