Answer 2

caozhy 谢谢你，但我是用vb.net来写的 htmlDoc.Click跑不出click

Answer 3

你好 Caozhy
AddHandler htmlDoc.Click, AddressOf Me.htmlDoc_Click
打出来还是会错

Answer 4

 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
