我正在尝试调用一个JS脚本，该脚本模拟对WebBrowser控件中某个元素的单击。
我目前正在这样做：
webBrowser2.Invoke(new Action(() =>
{
HtmlElement head = webBrowser2.Document.GetElementsByTagName("head")[0];
HtmlElement testScript = webBrowser2.Document.CreateElement("script");
IHTMLScriptElement element = (IHTMLScriptElement)testScript.DomElement;
element.text = "function simulate(g,c){var e=extend(defaultOptions,arguments[2]||{});var b,f=null;for(var d in eventMatchers){if(eventMatchers[d].test(c)){f=d;break}}if(!f){throw new SyntaxError('Only HTMLEvents and MouseEvents interfaces are supported')}if(document.createEvent){b=document.createEvent(f);if(f=='HTMLEvents'){b.initEvent(c,e.bubbles,e.cancelable)}else{b.initMouseEvent(c,e.bubbles,e.cancelable,document.defaultView,e.button,e.pointerX,e.pointerY,e.pointerX,e.pointerY,e.ctrlKey,e.altKey,e.shiftKey,e.metaKey,e.button,g)}g.dispatchEvent(b)}else{e.clientX=e.pointerX;e.clientY=e.pointerY;var a=document.createEventObject();b=extend(a,e);g.fireEvent('on'+c,b)}return g}function extend(a,c){for(var b in c){a[b]=c[b]}return a}var eventMatchers={HTMLEvents:/^(?:load|unload|abort|error|select|change|submit|reset|focus|blur|resize|scroll)$/,MouseEvents:/^(?:click|dblclick|mouse(?:down|up|over|move|out))$/};var defaultOptions={pointerX:0,pointerY:0,button:0,ctrlKey:false,altKey:false,shiftKey:false,metaKey:false,bubbles:true,cancelable:true};function TestClick(){simulate(document.getElementById('flls').firstChild,'click')};";
head.AppendChild(testScript);
webBrowser2.Document.InvokeScript("TestClick");
string TestUrl = webBrowser2.Url.AbsoluteUri;
if (TestUrl.Equals(expected))
{
HasSucceeded = 1;
}
else
{
// No test
}
}));
长模拟功能来自另一个StackOverflow答案。当我在IE9的Web开发工具控制台中键入此命令时，它可以正常工作，但此脚本根本不起作用。我究竟做错了什么？

我在下面说的是不正确的。您的语法是正确的，webBrowser2.Document.InvokeScript("TestClick")应该和webBrowser2.InvokeScript("TestClick")做同样的工作。我将尝试您的代码，然后返回此处。
我认为正确的语法应该是这样的：
webBrowser2.Document.InvokeScript("TestClick()");
注意
()之后的TestClick。或者您宁愿这样做：
webBrowser2.InvokeScript("TestClick");

最初加载到WB的HTML出现了问题，也许您应该在问题中包括它。以下仅是代码的副本（在
this.webBrowser2.DocumentText之外），并且确实可以正常工作，TestClick被调用。 private void Form1_Load(object sender, EventArgs e)
{
this.webBrowser2.DocumentText = "<body><div id=flls><button onclick='alert(true)'>go</button></div></body>";
this.webBrowser2.DocumentCompleted += webBrowser2_DocumentCompleted;
}
void webBrowser2_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
HtmlElement head = webBrowser2.Document.GetElementsByTagName("head")[0];
HtmlElement testScript = webBrowser2.Document.CreateElement("script");
IHTMLScriptElement element = (IHTMLScriptElement)testScript.DomElement;
element.text = "function simulate(g,c){var e=extend(defaultOptions,arguments[2]||{});var b,f=null;for(var d in eventMatchers){if(eventMatchers[d].test(c)){f=d;break}}if(!f){throw new SyntaxError('Only HTMLEvents and MouseEvents interfaces are supported')}if(document.createEvent){b=document.createEvent(f);if(f=='HTMLEvents'){b.initEvent(c,e.bubbles,e.cancelable)}else{b.initMouseEvent(c,e.bubbles,e.cancelable,document.defaultView,e.button,e.pointerX,e.pointerY,e.pointerX,e.pointerY,e.ctrlKey,e.altKey,e.shiftKey,e.metaKey,e.button,g)}g.dispatchEvent(b)}else{e.clientX=e.pointerX;e.clientY=e.pointerY;var a=document.createEventObject();b=extend(a,e);g.fireEvent('on'+c,b)}return g}function extend(a,c){for(var b in c){a[b]=c[b]}return a}var eventMatchers={HTMLEvents:/^(?:load|unload|abort|error|select|change|submit|reset|focus|blur|resize|scroll)$/,MouseEvents:/^(?:click|dblclick|mouse(?:down|up|over|move|out))$/};var defaultOptions={pointerX:0,pointerY:0,button:0,ctrlKey:false,altKey:false,shiftKey:false,metaKey:false,bubbles:true,cancelable:true};function TestClick(){simulate(document.getElementById('flls').firstChild,'click')};";
head.AppendChild(testScript);
webBrowser2.Document.InvokeScript("TestClick");
}
