regex replace

[johns221b]

var string="removespace : dont remove spaces";

need a regex which replaces all spaces before and after colon ':' .

above variable must be returned as

"removespacedont remove spaces"

[astupidname]

var string="removespace : dont remove spaces";
var str = string.replace(/\s+:\s+/g, ''); //insert colon : in the '' if you want the colon left in
alert(str);
