Question

How would I call a function in Javascript on a loaded site in a Windows Form Application web browser? For those that have used Chrome, I’m looking to call Javascript like you can with the Javascript console.

Answer 1

Here is the answer:

        WebBrowser wb = new WebBrowser;
        wb.Navigate( ... link or Uri ...)

        object[] args = new object[1];
        args[0] = 12';
        wb.Document.InvokeScript("functionName", args);

InvokeScript runs javascript functions. if you have a javascript function like function check(value){...} than your functionName is “check” and your args array hold value, if you have more parameters you can fill your args as much as parameters you want. The code above runs the javascript function as functionName(12);

If you want to access any element you can use this code:

wb.Document.GetElementById(“ControlId”)
.InnerText = “Bla bla”
.InvokeMember(“click”)
