问题
I have a code that clicks an html element but it doesn't fire its java script code, in VBA I used to call "initEvent" in order to invoke a java script event. I have searched the web and haven't found a suitable solution.
There's a working solution, but it's not quite useful in most cases, placing a java script code in the url and navigating to it, however there's a need for the location of the html element which is a problem sometimes.
The code I use in order to do a click in the html element :
el.InvokeMember("onclick");
Also tried :
el.InvokeMember("click");
The code that I place in the url and find not too much useful :
wb.Navigate("javascript: document.getElementsByClassName('something')[0].click();void(0);");
I hope to receive a working solution, thanks in advance.

I've solved it, a very original solve I'd say. So basically, I've thought about it this way. Finding an element that I already have is not comfortable at all, so the java script navigate didn't seem useful, however, I thought of changing it to fit any element, the question was how.
The answer I came up with, what if I'd focus the specific element and then use a javascript to click on the focused element, and it worked.
So the fixed code :
el.Focus();
wb.Navigate("javascript: document.activeElement.click();void(0);");
I hope it'll be useful to some of you.
