Hi, is there any way to cast EvalScript into Elements array, if the script actually return elements? Below there is an example:

Code: C#
EO.WebBrowser.DOM.Element [] elements = webView1.EvalScript("document.getElementsByTagName(\"input\")") as EO.WebBrowser.DOM.Element [];



Thanks in advance, your product is great!!

Hi,

You would cast it to a JSObject, then to a JSArray object:

Code: C#
//Cast the return value to a JSArray object
JSObject obj = (JSObject)webView1.EvalScript("....");
JSArray array = obj.ToArray();

I do not believe there is built-in support to cast it directly to a typed array. However once you have a JSArray, you can loop through it to cast each array element into a typed element:

Code: C#
//Cast a JSArray object to a DOM.Element array
DOM.Element[] elements = new DOM.Element[array.Length];
for (int i = 0; i < elements.Length; i++)
    elements[i] = array[i].CastTo<DOM.Element>();


Note that you must use JSObject.Cast method to cast the array element.

Hope this helps. Please feel free to let us know if you still have any more questions.

Thanks!
