我试图在我的中调用 JavaScript 方法WebBrowser

WebBrowser webBrowser = new WebBrowser();
webBrowser.NavigateToString(html);
webBrowser.LoadCompleted += ((s, r) =>
{
         try
         {
                 object tmp = webBrowser.InvokeScript("GetData");
         }
         catch (Exception exc)
         {
         }
});

这是HTML

<html><head>
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1">
<title></title>

<script type="text/javascript">
    function GetData ()
    {
        return 50;
    }

</script>

但是当我调用 javascript 时:

object tmp = webBrowser.InvokeScript("GetData");

我得到Exception

信息:

An unknown error has occurred. Error: 80020006.

质押追踪:

   at Microsoft.Phone.Controls.WebBrowserInterop.InvokeScript(String scriptName, String[] args)

您需要设置WebBrowser.IsScriptEnabledtruefalse默认情况下)
