Question

我正在使用VS 2005和WebBrowser控件。当我使用组件导航到指定页面时，我得到方案错误，例如“在此页面上的javascript场景错误”和两个按钮：是或否执行场景。如何防止警报窗口并在没有此消息的情况下继续浏览？

Answer 1

尝试

WebBrowser1.ScriptErrorsSuppressed = true;

Answer 2

试试这个

HtmlElement head = WebBrowser1.Document.GetElementsByTagName("head")[0];
HtmlElement scriptEl = WebBrowser1.Document.CreateElement("script");
IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement;
string alertBlocker = @"window.alert = function () { }; window.confirm=function () { };";
element.text = alertBlocker;
head.AppendChild(scriptEl);
WebBrowser1.ScriptErrorsSuppressed = true;

Answer 3

    Private Sub WebBrowser1_StatusTextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles WebBrowser1.StatusTextChanged
        On Error Resume Next
        Dim head As HtmlElement = WebBrowser1.Document.GetElementsByTagName("head")(0)
        Dim script As HtmlElement
        script = WebBrowser1.Document.CreateElement("script")
        script.SetAttribute("type", "text/javascript")
        Dim alertBlocker As String = "window.alert = function () { }; window.confirm=function () { }; "
        script.SetAttribute("text", alertBlocker)
        head.AppendChild(script)
    End Sub
