jquery - onkeyup - replace input and copy to another input

The old inline js code looked like this:

onchange="alias_generator(this,document.forms['category_form'].alias)" onkeyup="alias_generator(this,document.forms['category_form'].alias)"

This just means: copy from the 1. input (title) (this) ... filter it with the alias_generator (that removes special character) and move it to the 2. input (alias).

i'am new to jquery and external js - would be great if so开发者_如何学JAVAmeone can help me with that.

allready did some that works onload, but does not update...

var title = document.forms['admin'].title;

var alias = document.forms['admin'].alias;

alias_generator(title,alias);

$(".myInputFieldClass").keyup(
    function(){
        cur_val = $(this).val(); // grab what's in the field
        // do stuff with cur_val so that it's what you want
        $(this).val(cur_val);
    }
);

That should do it. Good luck.

$(document.forms["admin"].title).keyup(function (e) { 
    var val = $(this).val();
    // Do stuff with val
    $(document.forms["admin"].alias).val(val);
})
