执行js务必在网页加载完成时执行，示例代码片段如下：

void CMyWebBrowserEvenrHandler::NavigateComplete2(CWebBrowserUI* pWeb, IDispatch* pDisp, VARIANT*& url){// 页面加载完毕才能执行js// execute js start IDispatch *pHtmlDocDisp = pWeb->GetHtmlWindow();IHTMLDocument2 *pHtmlDoc2 = NULL;HRESULT hr = pHtmlDocDisp->QueryInterface(IID_IHTMLDocument2, (void**)&pHtmlDoc2);pHtmlDocDisp->Release();if (SUCCEEDED(hr) && pHtmlDoc2 != NULL){CComQIPtr<IHTMLWindow2> pHTMLWnd;pHtmlDoc2->get_parentWindow(&pHTMLWnd);if (SUCCEEDED(hr) && pHTMLWnd != NULL){//CComBSTR bstrjs = SysAllocString(_T("document.documentElement.style.overflow = 'hidden'"));//去除水平方向滚动条  CComBSTR bstrjs = SysAllocString(_T("document.documentElement.style.overflowY = 'hidden'"));//去除竖直方向滚动条  CComBSTR bstrlan = SysAllocString(_T("javascript"));VARIANT varRet;pHTMLWnd->execScript(bstrjs, bstrlan, &varRet);}}// execute js end}
