javascript - Passing in a key results in extra characters in my firebase URL, how do I remove them? -

when placing "key" variable inside of string, displays 'simplelogin%3a5' instead of 'simplelogin:5'. there way pass in latter?

  var populatetasks = function(date, key){     $scope.ref = new firebase("https://myfirebase.firebaseio.com/users/"+key+"/tasks");      }; 

results in: https://myfirebase.firebaseio.com/users/simplelogin%3a5/tasks need: https://myfirebase.firebaseio.com/users/simplelogin:5/tasks

var uri = "//what need convert"; var uri_dec = decodeuricomponent(uri); var res = uri_dec;
