string.replace not only accepts string as first argument but also it accepts regex as first argument. So put _ within regex delimiters / and aslo add g modifier along with that. g called global modifier which will do the replacement globally.
string.replace
_
/
g
g
App.filter('underscoreless', function ()
return function (input)
return input.replace(/_/g, ' ');
;
);
input
input
simple, just use an if stmt for condition checking.

Here's a generic replace filter alternative
App.filter('strReplace', function ()
return function (input, from, to) ;
);
Use it as follows in your HTML:
strReplace:'_':' '
Minor note: Any HTML tags in the to parameter will cause the expression to fail due to Angular content security rules.

This is for AngularJS 1.x.
App here represents the object you get back from creating your Angular app as follows: var App = angular.module('myApp', ['some-dependency', 'some-other-dependency']);– John Rix

App
var App = angular.module('myApp', ['some-dependency', 'some-other-dependency']);
This simple function can do it:
public getCleanedString(cadena)
cadena = cadena.replace(/_/g, ' ');
return cadena;
What question are you answering? They want to replace underscore with space.

There is a easyer method:
You could replace it inline without a defined filter. This is the way.
This example its for replace just in the view.
value.replace(/_/g, ' ')
I hope its could help in a simple change, if you want to change in more places, use the filter.
BratisLatas I liked your method, however it appears to only replace only one instance, not multiple.

I don't think that's a valid angular expression. It does work if the first argument is a string, but if using the regular expression, I get
