Getting button to click using javascript

I have a web app that I want to click a file selector button on but it doesnt work - or rather I can get it to work but only if I click on the pane that the button is in before PAD tries to call the click event/function.

function ExecuteScript()
{
document.window.focus(); getElementById('FileSelector').click();
}

the above it what Im trying but as I say, it doesnt work unless I click in the correct section - Ive tried using the Hover over UI element and then sending a click but that doesnt work either, I suspect as its not finding the element to click. Can anybody help? This is driving me nuts!

Why are you using the .window.focus() method in your function? Are you using the Run JavaScript action under the Scripting actions group? I would suggest using the Run JavaScript function on web page action under the Browser automation actions group. When you provide the browser instance that you want to execute the function on, you will not need to focus a window.

I am using the 'Run JavaScript function on web page' and providing the browser instance - a colleague said adding the window.focus() method might help

The way I see it is that all you need is this:

function ExecuteScript() { document.getElementById('FileSelector').click(); }

Alternatively, since these file selector buttons are actually part of the browser UI and not as much the web UI, you can use the Press button in window or Click UI element in window actions under the UI automation actions group. Those usually work fine with these buttons.

That doesnt work - thats what I tried first and only works if I manually click into the browser at the right hand side of the page where the button is. I did try also the press button and click UI elements but these dont work either, I get an error that it cant find the button or element

You might need to modify the selector there. Especially the parent window selector. For browser windows, it will contain the page title for when you captured it. If the page title can change, so will the title used in the selector. So, you need to remove the name parameter:

This is the selector when captured via Browser automation actions. When you capture it via UI automation actions, the selector will be different, and will have a parent window.

It will never work if you use the same element in UI automation actions. If you try using UI automation actions, you must recapture the element to generate a proper selector.
