问题描述
我有对WP7的方法 InvokeScript 一些困难：
I have some difficulties with the method InvokeScript on wp7:
webBrowser1.InvokeScript("eval", string.Format("document.getElementsByName('email').value='{0}'", _email));
webBrowser1.InvokeScript("eval", string.Format("document.getElementsByName('pass').value='{0}'", _pass));
webBrowser1.InvokeScript("eval", "document.forms[0].submit();");
不幸的是，当我尝试提交信息时，使用（document.forms [ 0] .submit（）），将引发异常，与消息：
Unfortunately, when I try to submit information, using (document.forms[0].submit()), an exception is thrown with the message:
发生未知错误。错误：？80020101
An unknown error has occurred. Error: 80020101.
什么可问题是
推荐答案
首先确保IsScriptingEnabled是真实的，但我相信你做到了。
First make sure that IsScriptingEnabled is to true, but I assume you did it.
您的问题可能是，你得太快调用代码。似乎DOM是没有准备好操作时，导航的事件发生。例如：
Your problem is probably that you call the code too soon. It seems that the DOM is not ready for manipulation when the Navigated event occurs. Example:
public partial class MainPage : PhoneApplicationPage
{
public MainPage()
{
InitializeComponent();
Wb.Navigated += new EventHandler<System.Windows.Navigation.NavigationEventArgs>(Wb_Navigated);
MouseLeftButtonDown += new MouseButtonEventHandler(MainPage_MouseLeftButtonDown);
Wb.NavigateToString("<html><body><form action='http://google.com/'></form></body></html>");
}
void Wb_Navigated(object sender, System.Windows.Navigation.NavigationEventArgs e)
{
Wb.InvokeScript("eval", "document.forms[0].submit();"); // Throws 80020101
}
private void MainPage_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
Wb.InvokeScript("eval", "document.forms[0].submit();"); // Works
}
}
