确认消息框，但在onclick触发后 [英] confirm messagebox, but after onclick firing

问题描述

我可以在页面创建期间创建Javascript确认消息框等

将它们添加到按钮属性（关于此的很多好帖子！）。但是如何在按下按钮后添加此事件



我创建了一个Is_Dirty例程检查我的页面上的字段更改

然后，如果用户点击退出按钮，则按钮我检查Is_Dirty = true和

想要询问你想退出而不保存吗？。这是一个代码

，如果Is_Dirty = True，那么我想显示消息框

并返回确认。因此，如果用户点击取消，然后他们回到了

表格。

我试过了：

1.）但是返回不能用在前面确认，我收到错误，但

无需确认即可工作。

Dim popupScript As String ="< script language =''javascript''>" &安培; _

"确认（"你确定要退出而不保存

更改吗？"）;" &安培; _

"< / script>"

Response.Write（popupScript）


有什么想法吗？ thanx。

解决方案

我会在ok按钮的onclick事件中尝试if语句，并且

真正的部分if语句，我会插入

page.getpostbackeventreference ....

听起来怎么样？

< blockquote>取消按钮是CausesValidation =False" "所以没有回帖。我这样做是为了处理页面验证，从而删除它。

所以我认为有一种方法可以把它放在流中吗？ HTML流媒体？

是否有其他页面属性可供访问？

因为我可以插入确认但没有返回？随着回报我得到了

" return statement of of function" Javascript页面错误??????

thanx。

如何在客户端实现Is_Dirty？

I can create Javascript confirm message boxes during page creation, etc
adding them to the button attributes (many good posts on this!). But how can
I add this event after the button is pressed?
I have created an Is_Dirty routine checking for field changes on my page
then if the user clicks on the "exit" button I check for Is_Dirty = true and
want to ask then "do you want to exit without saving?". It''s a code behind
where if the value of Is_Dirty = True then I want to display the messagebox
with return confirm. So if the user clicks "cancel" then they are back on the
form.
I''ve tried:
1.) But return can not be used in front of confirm, I get an error, but
works without confirm.
Dim popupScript As String = "<script language=''javascript''>" & _
"confirm(""Are you sure you want to exit without saving
changes?"");" & _
"</script>"
Response.Write(popupScript)

Any ideas? thanx.

解决方案

I would try an if statement inside the onclick event of the ok button and for
the true part of the if statement, I would insert the
page.getpostbackeventreference ....
How does that sound?

The cancel button is "CausesValidation="False" " so there is no post back. I
do this to handle the page validation, thus, removing it.
So I thought there was a way to put it in the stream somehow? HTML Stream?
Is there another page property to access for this?
As I can insert the confirm but without the return? With the return I get
"return statement out of function" Javascript page error??????

thanx.

What about implementing Is_Dirty on client side?
