在AngularJs中的string.Replace

Question

With c# there is a string.Replace-method. Like This:

string oldString = "stackoverflow";   

string newString= oldString.Replace("stackover","");

Output: flow

Can I do something similar to this with AngularJs?

My try doesn't work:

var oldString = "stackoverflow";

$scope.newString= oldString.Replace("stackover","NO");

Answer 1

In Javascript method names are camel case, so it's replace , not Replace :

$scope.newString = oldString.replace("stackover","NO");

Note that contrary to how the .NET Replace method works, the Javascript replace method replaces only the first occurrence if you are using a string as first parameter. If you want to replace all occurrences you need to use a regular expression so that you can specify the global (g) flag:

$scope.newString = oldString.replace(/stackover/g,"NO");

See this example.

Answer 2

The easiest way is:

var oldstr="Angular isn't easy";
var newstr=oldstr.toString().replace("isn't","is");

Answer 3

var oldString = "stackoverflow";
var str=oldString.replace(/stackover/g,"NO");
$scope.newString= str;

It works for me. Use an intermediate variable.
