问题描述
多次单击按钮后，if子句中的vb代码不会执行。 （不执行后续点击操作）。请帮忙。
The vb code inside the if clause does not execute after the button has been clicked more than once. (Does not execute subsequent click actions). Please help.
<script type = "text/javascript">
function Confirm() {
var confirm_value = document.createElement("INPUT");
confirm_value.type = "hidden";
confirm_value.name = "confirm_value";
if (confirm("Confirm to Delete Account")) {
confirm_value.value = "Yes";
} else {
confirm_value.value = "No";
}
document.forms[0].appendChild(confirm_value);
}
</script>
<body>
<form id="form1" runat="server"> <%-- HTML code --%>
<asp:Button ID="Delete_Account" runat="server" OnClick="Delete_Account_Click"
OnClientClick=" Confirm()" Text="Delete Account" Width="250px"
BorderColor="Silver" Font-Size="19px" Height="45px" Font-Bold="True"
Font-Names="Times New Roman" />
</form>
</body>
VB code
Dim confirmValue As String = Request.Form("confirm_value")
If confirmValue = "Yes" Then
'actions to perform
end if
推荐答案
更改你的确认功能就像这个：
Change your confirm function like this:
function confirmDelete () {// note that it is custom to name methods with lower case letter
return confirm("You're about to delete the account. Are you sure?");
}
并改变你的按钮
And change your button to
<asp:Button ID="Delete_Account" runat="server" OnClick="Delete_Account_Click"
OnClientClick=" javascript return confirmDelete();" Text="Delete Account" Width="250px"
BorderColor="Silver" Font-Size="19px" Height="45px" Font-Bold="True"
Font-Names="Times New Roman" />
通过从客户端脚本返回false来防止服务器往返，您的服务器点击处理程序将永远不会触发。
By returning false from client side script you're preventing server round-trip, your server click handler will never trigger.
