我试过这个:
string newScript = textBox1.Text;
HtmlElement head = browserCtrl.Document.GetElementsByTagName("head")[0];
HtmlElement scriptEl = browserCtrl.Document.CreateElement("script");
lblStatus.Text = scriptEl.GetType().ToString();
scriptEl.SetAttribute("type", "text/javascript");
head.AppendChild(scriptEl);
scriptEl.InnerHtml = "function sayHello() { alert('hello') }";
scriptEl.InnerHtml和scriptEl.InnerText都给出了错误:
System.NotSupportedException: Property is not supported on this type of HtmlElement.

at …我最近需要更新一个旧的FoxPro遗留应用程序,该应用程序使用Internet Explorer Automation来通过单击某些href链接并将数据输入到表单并提交来驱动网页内容.
这曾经工作得很好但是用IE 11(Windows 10)以及IE 10(Windows 7)检查Windows的最新版本我发现任何对元素的点击事件调用都没有效果而且它们无声地失败 - 没有错误,但也没有点击.
o = CREATEOBJECT('InternetExplorer.Application')
o.visible = .t.
o.Navigate('http://test.com/ControlBasics.wcsx')
wait window 'page loading...' timeout 1.5
* Target object has no id so navigate DOM to get object reference
oLinks = o.Document.getElementsByTagName('a')
oLink = oLinks.item(0)
oLink.Click()
* o.navigate(oLing.href) && works but not sufficient
o.document.getElementById('txtName').value = 'Rick'
oButton = o.document.getElementById('btnSubmit')
oButton.Click()
在上面的代码中,.click()事件触发器都没有任何效果.然而,对文本框的分配工作正常,因此页面是脚本化的.
有人知道发生了什么变化或者可能会对行为产生什么影响,以便自动化以前工作的事件代码不再有效吗？
