AngularJS Question

How do I call an Angular.js filter with multiple arguments?

As from the documentation, we can call a filter such as date like this:

{{ myDateInScope | date: 'yyyy-MM-dd' }}

Here date is a filter that takes one argument.

What is the syntax to call filters with more parameters both from templates and from JavaScript code?

In templates, you can separate filter arguments by colons.

{{ yourExpression | yourFilter: arg1:arg2:... }}

From Javascript, you call it as

$filter('yourFilter')(yourExpression, arg1, arg2, ...)

There is actually an example hidden in the orderBy filter docs.


Let's say you make a filter that can replace things with regular expressions:

myApp.filter("regexReplace", function() { // register new filter

  return function(input, searchRegex, replaceRegex) { // filter arguments

    return input.replace(RegExp(searchRegex), replaceRegex); // implementation


Invocation in a template to censor out all digits:

<p>{{ myText | regexReplace: '[0-9]':'X' }}</p>
