[英]confirmation popup message (ASP.NET/VB)
I want to have a confirmation message box pop up when a user clicks the cancel button on a form.当用户单击表单上的取消按钮时,我希望弹出一个确认消息框。 I believe this would be the correct javascript code:
我相信这将是正确的 javascript 代码:
function confirmation() {
var answer = confirm("Are you sure you want to cancel? Any information you have entered will be discarded.")
if (answer) {
window.location = "index.htm";
}
}
But, I'm not sure how I can call the function with VB from my code behind page.但是,我不确定如何从我的页面后面的代码中使用 VB 调用 function。
On your cancel button add this markup attribute在您的取消按钮上添加此标记属性
OnClientClick="return confirmation();"
