我正在开发一个应用程序，用户可以在其中输入所需的地址，然后按按钮。该地址可以在WebBrowser.net windows 应用程序中的控制。我知道你可以运行 javascriptWebBrowser通过使用WebBrowser1.DocumentText，并通过调用脚本WebBrowser1.Document.InvokeScript ...
我对此有一点问题，我想知道是否有人可以向我展示正确的方法来做到这一点。
CODE:
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
下面是我认为应该有效的另一段代码，但我仍然收到脚本错误“此页面上的脚本中发生错误”第 1 行 CHAR 124 错误预期 ';'代码 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> " +
"<script type='text/javascript'> " +
"var geocoder; " +
"var map; " +
"function initialize(address) { " +
"geocoder = new google.maps.Geocoder(); " +
"var myOptions = { zoom: 16 } " +
"geocoder.geocode({ 'address': address }, function (results, status) { map.setCenter(results[0].geometry.location); " +
"var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); " +
"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})
我非常感谢你的帮助

这是另一段与前两段稍有不同的代码，它包含从实际运行谷歌地图脚本的 html 中提取的 if else 语句。
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> " +
"<body> <div id='map_canvas' style='width:100%; height:100%'></div> </body> </html>"
WebBrowser1.Document.InvokeScript("initialize")
