我在我的 asp 页面中仅使用CSS3进行了以下模态对话框(弹出)以进行用户注册:
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);
background: -o-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,我使用了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,我想要对现有电子邮件 ID 进行服务器端验证。如果用户输入的电子邮件 ID 已存在于数据库中,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。有没有办法使用js来做到这一点?
