使用Awesomium將值提交到html文本框-vb.net

[英]Submit value to html textbox with awesomium - vb.net

我正在使用此代碼從列表框拆分文本:

For Each Item As Object In ListBox1.SelectedItems
                TextBox2.AppendText(Item.ToString + Environment.NewLine)
            Next
            Dim str As String = TextBox2.Text
            Dim leftPart As String = str.Split(":")(0)
            Dim test As String = TextBox2.Text
            Dim phrase As String = test.Substring(test.IndexOf(":"c) + 1)

和此代碼將值提交到html文本框

WebControl1.ExecuteJavascript("document.getElementById('email').value=""" + leftPart + """;")
                Dim leftpar2 As String
                leftpar2 = phrase
                MsgBox(phrase)
                Try
                    WebControl1.ExecuteJavascript("document.getElementById('pass').value=""" + leftpar2 + """;")
                Catch ex As Exception
                    MsgBox(ex.ToString)
                End Try

具有ID(電子郵件)的文本框可以正常工作
但是另一個(通過)總是空的,我試圖彈出(短語)的值它得到正確的值

我試圖將字符串分配給變量(詞組)

Dim phrase As String = "test"   

它工作正常,有人可以告訴我做錯了什么嗎?

好吧,我已經下載了該組件並按照您的方式進行了操作

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    If (TextBox1.Text.Length < 3 Or TextBox1.Text.IndexOf(":") < 1) Then
        MsgBox("Please type value in format like {email:password}")
        Return
    End If

    ' Get the values and parse it
    Dim sources As String() = TextBox1.Text.Split(":")

    ' Now, we try to set it to page
    ' pay attention at `document.querySelector('#id')` it should be ID of the element
    WebControl1.ExecuteJavascript(String.Format("document.querySelector('#email').value = '{0}'", sources(0)))
    WebControl1.ExecuteJavascript(String.Format("document.querySelector('#password').value = '{0}'", sources(1)))
End Sub

這是我的登錄頁面代碼(WebControl組件中加載的頁面)

<body>
    <input type="email" id="email" /> 
    <input type="password" id="password" /> 
    <button id="loginButton">Login</button>
</body>

一切似乎都正常

您可以運行我的示例:將文本框,webcontrol和按鈕放在表單上,​​將WebControl1.Source設置為“ http://cafe-ht.ml/fake/fake-login.html ”,然后單擊按鈕復制處理程序
