multiple replaces with javascript

Question

In PHP, you do this to replace more then one value at a time.

<?php
$string = "jak har en mamma";

$newstring = str_replace(array('jak', 'mamma'), array('du', 'pappa'), $string);

echo $newstring;
?>

How do you do this in javascript?

Answer 1

Use javascript's .replace() method, stringing multiple replace's together. ie:

var someString = "foo is an awesome foo bar foo foo";
var replaced = somestring.replace(/foo/g, "bar").replace(/is/g, "or");
// replaced now contains: "bar or an awesome bar bar bar bar"

Answer 2

You could do:

var string = "jak har en mamma";

string = string.replace(/(jak)|(mamma)/g,function(str,p1,p2) {
        if(p1) return 'du';
        if(p2) return 'pappa';
    });

or:

var string = "jak har en mamma";

string = string.replace(/jak/g,'du').replace(/mamma/g,'pappa');

Answer 3

Still didnt work to replace spaces.

I did this and it worked:

var $val = $(this).val().replace(",", ".").split(' ').join('');

Thanks anyway!
