onclick事件。

Hi
How can I run a java script function before a form is submited back to the
server.
What I wish to do is have a upload form that when a user clicks the submit
button a javascript function opens a second window after this the buttons
onclick event should be run.
Is any of this possible.
推荐答案
使用常规HTML而不是使用表单上的提交按钮按钮
上面有一个调用函数的onClick事件处理程序。
在该函数中,做任何你喜欢的事情,当你完成时调用
formName.submit()

Instead of using a submit button on your form, use a regular HTML button
that has an onClick event handler on it that calls a function.
In that function, do whatever you like and when you are done invoke
formName.submit()

好的,
但是需要什么Serverside代码才能确保按下提交按钮
而不是清除或浏览器刷新按钮。

Ok then,
But what Serverside code is required to make sure the submit button was
pressed and not a clear or browser refresh button.

而不是使用提交你的表单上的按钮,使用一个常规的HTML按钮

调用javascript函数然后返回true。
表单将照常提交。
例如
myButton.Attributes.add(" onclick"," doThisFirst();");
页面
< script>
函数doThisFirst(){
alert(''你好'');
返回true;
}
< / script>

call the javascript function and then return true.
the form will be submitted as normal.
eg
myButton.Attributes.add("onclick","doThisFirst();" );
on the page
<script>
function doThisFirst() {
alert(''hello'');
return true;
}
</script>
