mshtml HTMLFormElement事件 [英] mshtml HTMLFormElement events
问题描述
大家好，
dev。环境：VS.Net2003 / C＃
我有一个带有Web浏览器控件的Windows窗体应用程序。我需要
捕获文档中表单的onsubmit事件，以便获取值并记录它们。
我试过这个：
1.
this.current_page = this.mydoc.Document as mshtml.HTMLDocumentClass;
if（this.current_page！= null）
{
mshtml.IHTMLElementCollection _forms = this.current_page.forms;
foreach（_forms中的mshtml.IHTMLFormElement _form）
{
（（mshtml.HTMLFormElementEvents2_Event）_form）.onsub mit + =
new mshtml.HTMLFormElementEvents2_onsubmitEventHandler
（MyDoc_onsubmit）;
}
}
2.
<相同，只是差异。 foreach>
foreach（mshtml.HTMLFormElementClass _form in this.forms）
{
_form.HTMLFormElementEvents2_Event_onsubmit + =
new mshtml.HTMLFormElementEvents2_onsubmitEventHandler
（MyDoc_onsubmit）;
.....
在codeproject上有2篇文章。 com，他们也不工作。
而且......没有成功。没有任何例外情况，一切都过去了，但是在页面上的表单子页面被阻止之后，即使是提交按钮
也不起作用。
我试图绕过这个并使用
浏览器的BeforeNavigate2事件（它可以工作）并检查是否有postdata。但是在那种情况下
我会松散具有GET方法的表格。
请，任何帮助都将受到高度赞赏。
谢谢
Sunny
Hi all,
dev. env.: VS.Net2003/C#
I have a windows form application with web browser control. I need to
capture the onsubmit event of the forms in the document in order to get
the values and log them.
I have tried this:
1.
this.current_page = this.mydoc.Document as mshtml.HTMLDocumentClass;
if (this.current_page != null)
{
mshtml.IHTMLElementCollection _forms = this.current_page.forms;
foreach (mshtml.IHTMLFormElement _form in _forms)
{
((mshtml.HTMLFormElementEvents2_Event)_form).onsub mit +=
new mshtml.HTMLFormElementEvents2_onsubmitEventHandler
(MyDoc_onsubmit);
}
}
2.
<same, just diff. foreach>
foreach (mshtml.HTMLFormElementClass _form in this.forms)
{
_form.HTMLFormElementEvents2_Event_onsubmit +=
new mshtml.HTMLFormElementEvents2_onsubmitEventHandler
(MyDoc_onsubmit);
.....
And there are 2 articles on codeproject.com, they do not work also.
And ... no success. There is no exceprions, everything passes, but after
that the form submition on the page is blocked, even the submit button
does not work.
I have tried to go around this and to use BeforeNavigate2 event of the
browser (it works) and to examine if there is postdata. But in that case
I''ll loose forms which has GET method.
Please, any help will be highly appreciated.
Thanks
Sunny

Hi Sunny，
您可以在onsubmitEventHandler中设置断点，以查找是否已调用此方法
。

Hi Sunny,
You can set break point in the onsubmitEventHandler to find if this method
was called.
