vb.net 载入任何网页，在WebBrowser鼠标任何地方点击，可以觸发事件-在线等
如题
我想在vb.net WebBrowser内
鼠标点击(double click 或是click)会，就会觸发事件
就像是点了button这样子即可

namespace Q689722
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.Navigate("http://echarts.baidu.com/echarts2/doc/example/bar1.html");
}
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
if (webBrowser1.Document != null)
{
var htmlDoc = webBrowser1.Document;
htmlDoc.Click += new HtmlElementEventHandler(htmlDoc_Click);
htmlDoc.MouseMove += new HtmlElementEventHandler(htmlDoc_MouseMove);
htmlDoc.ContextMenuShowing += new HtmlElementEventHandler(htmlDoc_ContextMenuShowing);
}
}
void htmlDoc_ContextMenuShowing(object sender, HtmlElementEventArgs e)
{
MessageBox.Show("right");
}
void htmlDoc_MouseMove(object sender, HtmlElementEventArgs e)
{
this.Text = e.ClientMousePosition.ToString();
}
void htmlDoc_Click(object sender, HtmlElementEventArgs e)
{
MessageBox.Show("click");
}
}
}
caozhy 谢谢你，但我是用vb.net来写的 htmlDoc.Click跑不出click
你好 Caozhy
AddHandler htmlDoc.Click, AddressOf Me.htmlDoc_Click
打出来还是会错
Public Class Form1
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("http://echarts.baidu.com/echarts2/doc/example/bar1.html")
End Sub
Private Sub WebBrowser1_DocumentCompleted(sender As Object, e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
If Not (WebBrowser1.Document Is Nothing) Then
Dim htmlDoc = WebBrowser1.Document
AddHandler htmlDoc.Click, AddressOf htmlDoc_Click
End If
End Sub
Private Sub htmlDoc_Click(sender As Object, e As HtmlElementEventArgs)
MsgBox("click")
End Sub
End Class
别的我就不写了
记得帮我采纳下哦。谢谢
