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.
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()
})
