当我尝试在web浏览器中运行javascript时，代码运行，但在它被执行后，我在一个白色页面上，右上角有一个数字值(在本例中为"1000")，带我离开我以前所在的网站
HtmlElement head = webBrowser1.Document.GetElementsByTagName("head")[0];
HtmlElement scriptEl = webBrowser1.Document.CreateElement("script");
IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement;
element.text = "function ScrollDown() { document.getElementsByClassName('scrollableitemclass').scrollTop = 1000 }";
head.AppendChild(scriptEl);
webBrowser1.Document.InvokeScript("ScrollDown");
谢谢你的帮助
你可以使用HtmlElement.ScrollIntoView滚动到你的Html元素。
请看下面的例子:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
}
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.DocumentText = "<html><body><span class="cls" id="el"> </body></html>";
}
void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
//for element with id
webBrowser1.Document.GetElementById("el").ScrollIntoView(true);
//for element with spesific
foreach (HtmlElement el in webBrowser1.Document.All)
{
if (el.GetAttribute("ClassName") == "cls")
{
el.ScrollIntoView(true);
}
}
}
}
