I'm looking for the javascript event that is triggered when a textbox is clicked? : I need to locate the trigger event that pops up the keyboard on a mobile device when a textarea is clicked, so I can fill a textarea popup I have created with the information in that textarea.  I also need to attach the textarea I have created to the mobile keyboard.

I am new to javascript, and struggling to find the trigger event in our website code.  Anyone able to help me on this one?
