[英]JavaScript confirm with ASP.NET
I am using JavaScript confirm in an ASP.NET program, the confirm window works when I want it to, however I am not sure how to retrieve whether the user clicks 'OK' or 'Cancel'. 我在ASP.NET程序中使用JavaScript确认,确认窗口在我想要的时候工作,但是我不知道如何检索用户是否单击“确定”或“取消”。
This is in the site master: 这是在站点主站:
<script type="text/javascript">
var confirmMsg = document.getElementById('MainContent_confirmMessageHidden');
if (confirmMsg != null) confirm(confirmMsg.value);
</script>
This is in the aspx.cs file: 这是在aspx.cs文件中:
private void Confirm(string msg)
{
//Response.Write("<script language = 'javascript'>window.alert('" + msg + "')</script>");
confirmMessageHidden.Value = msg;
confirmMessageHidden.Visible = true;
}
How can I retrieve the choice of the user? 如何检索用户的选择?
You need to use return value of javascript confirm function. 你需要使用javascript确认函数的返回值。 For example, 例如,
...
if (confirmMsg != null) {
var answer = confirm(confirmMsg.value);
if (answer) {
alert('OK Clicked');
}
else {
alert('Cancel Clicked');
}
}
...
Choose appropriate action instead of alerts as per the functionality needed by you. 根据您所需的功能选择适当的操作而不是警报。
EDIT: 编辑:
A sample code to prevent navigation using confirm 使用确认阻止导航的示例代码
<script type="text/javascript">
function doConfirm() {
var confirmMsg = document.getElementById('MainContent_confirmMessageHidden');
if (confirmMsg != null) {
return confirm(confirmMsg.value);
}
return true;
}
</script>
<a href="link to some other page" onclick="return DoConfirm();" />
<input type="sumbit" value="Click Me" onclick="return DoConfirm();" />
You could use a conditional action based on confirm choose: 您可以使用基于确认选择的条件操作:
for example something like 比如说像
if (confirm(confirmMsg.value))
{
document.location('<your_process_page_url.aspx>?confirm=1');
}
else
{
document.location('<your_process_page_url.aspx>?confirm=0');
}
Then in process page you can retrieve the choose by 然后在流程页面中,您可以检索选择
<%
var choose = Request.QueryString["confirm"];
%>
