Perform keystroke onload using jQuery

Question

As opposed to this question (https://stackoverflow.com/revisions/3368578/1), I DO want to print text in a text box on the loading of a page.

I don't know much about jQuery so I'm not even sure this is possible. I want to set focus on a field onload, and then perform a backspace keystroke in that field (not simulate it). This seems on track(https://stackoverflow.com/a/16122568/3748951), but I don't know how to trigger the event and assign the value to the textbox simply onload. I would greatly appreciate any help.

So, on load, you want to focus and remove the last character then perform the event attache to that input? — Karl-André Gagnon, Jun 17 '14 at 14:51
I don't think it's even as complex as that. I just want to set focus on load, then perform a single backspace in the field I have set focus on, that's it. — Mr. Two-Arms, Jun 17 '14 at 14:58
When you are saying on load (based on your text at the top of the question), you mean on document ready, right? — Kenny, Jun 17 '14 at 14:59
@Mr.Two-Arms why do you want to do a back space? To trigger an event or just remove the last character of the input? — Karl-André Gagnon, Jun 17 '14 at 15:02
@MiguelRipoll, if those are equivalent, then yes. As I said, I don't know much about jQuery! — Mr. Two-Arms, Jun 17 '14 at 15:03
@Mr.Two-Arms ready and load are not equivalent, but that's not your question here. — Karl-André Gagnon, Jun 17 '14 at 15:05
@Mr.Two-Arms on document ready waits until HTML is parsed and page will keep loading as always, on load wait until all scripts and styles are loaded. — Kenny, Jun 17 '14 at 15:05

I guess that's what you want, don't need trigger simulate a backspace :

$(document).ready(function(){
    //Select your input here
    $('input').val(function(_, old){
        return old.slice(0, -1); //Remove the last character
    }).focus()
})

That's it. I was trying to do a backspace using Event but it wasn't working. – Kenny Jun 17 '14 at 15:12
@MiguelRipoll Yeah, those are fakes events. It's like when you use `trigger('click')` on an `a`, it will not redirect to the `href`. – Karl-André Gagnon Jun 17 '14 at 15:14

Thanks @Karl-AndréGagnon this was my first foray into the stackoverflow boards, what a helpful community of people :) – Mr. Two-Arms Jun 17 '14 at 15:18
@Mr.Two-Arms Of course it is, but on the other hand, you may find it harsh if you ask bad question... Glad it help anyway! – Karl-André Gagnon Jun 17 '14 at 15:21
