我没有得到javascript。你如何使用它？ [英] I don't get javascript. How do you use it?
问题描述
您好。
我刚读完了两篇关于javascript的文章：
http://msdn2.microsoft.com/en-us/lib...23（VS.80）.aspx
我在WIN XP Pro，SP2上尝试了VS2005，SP1，VB，.NET 2.0，ASP.NET 2.0中的一些javascript测试
。 br />
这真的很简单。我在页面上放了一个按钮并将onClick编码为
这个：
< asp：Button ID =" Button1" RUNAT = QUOT;服务器" Style =" z-index：103;左：528px;
位置：绝对;上：392px文本= QUOT;按钮和QUOT;的OnClick = QUOT; ShowCal" />
这是函数：
< script type =" text / javascript" language =" javascript">
函数ShowCal（）{
var x = Button1.Style.z - index;
alert（ x）;
}
< / script>
它不会让我运行程序说 ''ShowCal''不是
的成员''ASP.default_aspx''"
如果javascript如此受欢迎，为什么我们不能使用它？
感谢任何帮助。
谢谢，
Tony
JavaScript是客户端的。 ASP.Net按钮的OnClick事件是
寻找服务器端功能。在这种情况下，你最好的选择是使用
普通HTML按钮，然后从HTML
按钮的onclick事件中调用javascript事件。

因为你没有调用它...< asp：Buttonwill
的OnClick事件导致页面发布返回（除非你使用AJAX或类似的东西）
并尝试运行服务器端方法...
将代码更改为以下：
< asp：Button ID =" Button1" RUNAT = QUOT;服务器" Style =" z-index：103;左：528px;
位置：绝对;上：392px文本= QUOT;按钮和QUOT;的OnClientClick = QUOT; ShowCal（）;" />
Hello Mark和Mark。
我试过Mark Fitzpatrick的方式和Mark Rae''的方式。无论哪种方式，
都没有给出错误，但它没有做任何事情。
< input id =" Button1" style =" z-index：103;左：496px;位置：绝对;
顶部：392px"
type =" button"值= QUOT按钮"的onClick = QUOT; ShowCal;" />
< asp：Button ID =" Button2" RUNAT = QUOT;服务器" Style =" z-index：104;左：688px;
位置：绝对;上：392px文本= QUOT;按钮和QUOT;的OnClientClick = QUOT; ShowCal（）;" />
当我点击Button1时，它什么都不做，并在页面上放置一个错误。在IE屏幕底部的
并没有做任何事情。当我点击Button2时，我可以在IE屏幕底部看到
进度条，但它什么也没做。
谢谢，
Tony

Hello.
I just finished reading two articles about javascript here:
http://msdn2.microsoft.com/en-us/lib...23(VS.80).aspx
I tried some javascript testing in VS2005, SP1, VB , .NET 2.0, ASP.NET 2.0
on WIN XP Pro, SP2.
It''s real simple. I put a button on a page and coded the onClick in it like
this:
<asp:Button ID="Button1" runat="server" Style="z-index: 103; left: 528px;
position: absolute; top: 392px" Text="Button" OnClick="ShowCal" />
Here is the function:
<script type="text/javascript" language="javascript">
function ShowCal() {
var x = Button1.Style.z - index;
alert(x);
}
</script>
It won''t let me run the program saying "''ShowCal'' is not a member of
''ASP.default_aspx''"
If javascript is so popular, why can''t i use it?
Any help would be gratefully appreciated.
Thanks,
Tony
JavaScript is client-side. The OnClick event of the ASP.Net button is
looking for a server-side function. Your best bet in this case is to use a
plain HTML button instead and call the javascript event from the HTML
button''s onclick event.

If javascript is so popular, why can''t i use it?Because you''re not calling it... The OnClick event of an <asp:Buttonwill
cause the page to post back (unless you''re using AJAX or something similar)
and try to run a server-side method...
Change your code to the following:
<asp:Button ID="Button1" runat="server" Style="z-index: 103; left: 528px;
position: absolute; top: 392px" Text="Button" OnClientClick="ShowCal();" />
Hello Mark and Mark.
I tried it both Mark Fitzpatrick''s way and Mark Rae''s way. Either way does
not give an error, but it does not do anything.
<input id="Button1" style="z-index: 103; left: 496px; position: absolute;
top: 392px"
type="button" value="button" onClick="ShowCal;" />
<asp:Button ID="Button2" runat="server" Style="z-index: 104; left: 688px;
position: absolute; top: 392px" Text="Button" onClientClick="ShowCal();" />
When i click Button1, it does nothing and puts an "Error on page" on the
bottom of the IE screen and does nothing. When i click Button2, i can see
the progress bar at the bottom of the IE screen, but it does nothing.
Thanks,
Tony
