在实际开发中，会发现设置其属性ScriptErrorssupPRessed无法达到屏蔽脚本错误效果，但是可以通过下面两种方式实现。
1.在DocumentCompleted事件中订阅Error处理，如下：
privatevoidwbGoogleMap_DocumentCompleted(objectsender, WebBrowserDocumentCompletedEventArgs e)
{
wbGoogleMap.Document.Window.Error +=newHtmlElementErrorEventHandler(Window_Error);
}voidWindow_Error(objectsender, HtmlElementErrorEventArgs e)
{e.Handled =true;}
2.在脚本中window.onerror中处理，如下：
window.onerror =function(error, url, line) {// log(error + "url:" + url + "lineNo:" + line);returntrue;
}
.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp{ background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }这样子能够很好屏蔽WebBrowser脚本错误提示，希望有所帮助！.csharpcode, .csharpcode pre
