Recognize the backspace and spacebar with jQuery

Question

when a user clicks the spacebar or backspace I need to create a variable that stores the action so I can use it to manipulate an array. I want the backspace to delete a value in an array and the spacebar to create a space. How can I do this?

Answer 1

Maybe this can help you:

$('body').keyup(function(e){    if(e.keyCode == 8){        // user has pressed backspace        array.pop();    }    if(e.keyCode == 32){        // user has pressed space        array.push('');    } }); 

Answer 2

try this

$(document).ready( function() {         $('#inputid').bind('keypress', function(e) {             if (e.which == 32){//space bar                 alert('space');             }             if (e.which == 8) {//backspace                 alert('back space');             }     });       });
