ユーザーが目的のアドレスを入力してボタンを押すことができるアプリケーションを開発しています。このアドレスはWebBrowser、.net Windows アプリケーションのコントロールにあります。WebBrowserを使用してJavaScript を実行しWebBrowser1.DocumentText、スクリプトを呼び出してWebBrowser1.Document.InvokeScript...

これにはほとんど問題がなく、誰かがそれを行うための正しい方法を教えてくれるかどうか疑問に思っていました.

コード：

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click

  Dim AddressMap As String

  AddressMap = AddressM.Text

  WebBrowser1.DocumentText = "<html><head><meta name='viewport' content='initial-scale=1.0, user-scalable=no' />" & _
    "<script type='text/javascript' src='http://maps.google.com.mx/maps/api/js?sensor=true&language;=es'></script>" & _
    "<script type='text/javascript'>" & _
    "var geocoder; var map;" & _
    "function initialize() " & _
    "{geocoder = new google.maps.Geocoder(); var myOptions = { zoom: 16, mapTypeId: google.maps.MapTypeId.ROADMAP()" & _
    "} var(address = " & AddressMap & ")" & _
    "geocoder.geocode({ 'address': address }, function (results, status) {" & _
                    "if (status == google.maps.GeocoderStatus.OK) {" & _
                        "map.setCenter(results[0].geometry.location);" & _
                        "var marker = new google.maps.Marker({" & _
                           " map: map," & _
                            "position: results[0].geometry.location });" & _
                    "} else {" & _
                    "}});" & _
     "map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);}" & _
     "</script></head><div id='map_canvas' style='width:100%; height:100%'></div></body></html>"

   WebBrowser1.Document.InvokeScript("Initialize")

End Sub

以下は、動作すると思われる別のコードですが、「このページのスクリプトでエラーが発生しました」というスクリプト エラーが表示されます。コード 0 URL about.blank

 WebBrowser1.DocumentText = "<html><head><script type='text/javascript' src='http://maps.google.com.mx/maps/api/js?sensor=false&language;=es'></script> " +

                           "function initialize(address) { " +
                           "geocoder = new google.maps.Geocoder(); " +

                           "map = new google.maps.Map(document.getElementById('map_canvas'), myOptions); " +

                           "</script> " +
                           "</head> " +
                           "<body> <div id='map_canvas' style='width:100%; height:100%'></div> </body> </html>"

WebBrowser1.Document.InvokeScript("initialize", New String() {AddressM.Text})

助けてくれてありがとう

これは、前の 2 つとは少し異なる別のコードで、実際に Google マップ スクリプトを実行する html から引き出された if else ステートメントが含まれています。

WebBrowser1.DocumentText = "<html><head><script type='text/javascript' src='http://maps.google.com.mx/maps/api/js?sensor=false&language;=es'></script> " +
                       "<script type='text/javascript'> " +
                       "var geocoder; " +
                       "var map; " +
                       "function initialize() { " +
                       "geocoder = new google.maps.Geocoder(); " +
                       "var myOptions = { zoom: 16, mapTypeId: google.maps.MapTypeId.ROADMAP } " +
                       "var(address = 'Miami Beach, Flordia') " +
                       "geocoder.geocode({ 'address': address }, " +
                       "function (results, status) { " +
                       "if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results[0].geometry.location); " +
                       "var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); " +
                       "} else { alert('Geocode was not successful !);}}); " +
                       "map = new google.maps.Map(document.getElementById('map_canvas'), myOptions); } " +
                       "</script> " +
                       "</head> " +

Windows フォーム - C#

private void Form1_Load(object sender, EventArgs e)
{
    // Put uri (http://www.example.com/page.html and c:\page.html is valid address)
    webBrowser1.Url = new Uri(@"C:\page.html");
}

private void button1_Click(object sender, EventArgs e)
{
    webBrowser1.Document.InvokeScript("initialize", 
            new string[] { textBox1.Text });
}

textBox1、button1およびという名前のこのコンポーネントを含むフォームが必要webBrowser1です。
