javascript - Replace string as you type -


i want create web-friendly image name user input on form. want replace spaces in user entered string dash user types.

my code replaces first space.

how replace all spaces dashes?

$('#form_model').keyup(function(event) {     var newtext = event.target.value;      newtext = newtext.replace(" ", "-");      $('#form_image').val(newtext+".png"); });

this done using regexpression g flag. g stand global, affects whole string , not first value.

here working fiddle:

$('#form_model').keyup(function(event) {    var newtext = event.target.value;    newtext = newtext.replace(/\s/g, "-");    $('#form_image').val(newtext+".png");  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <input id="form_model" type="text">  <input id="form_image" type="text" readonly>
