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 this code, jsondata is our array and in function return we are checking the 'version' present in the jsondata.

var as = $filter('filter')(jsondata, function (n,jsondata){
   return n.filter.version==='V.0.3'
});

console.log("name is " + as[0].name+as[0]);

like this: 

var items = $filter('filter')(array, {Column1:false,Column2:'Pending'});

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.

Example:

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>

If you need two or more dealings with the filter, is possible to chain them:

{{ value | decimalRound: 2 | currencySimbol: 'U$' }} 
// 11.1111 becomes U$ 11.11

If you want to call your filter inside ng-options the code will be as follows:

ng-options="productSize as ( productSize | sizeWithPrice: product )  for productSize in productSizes track by productSize.id"

where the filter is sizeWithPriceFilter and it has two parameters product and productSize

i mentioned in the below where i have mentioned the custom filter also , how to call these filter which is having two parameters

countryApp.filter('reverse', function() {
    return function(input, uppercase) {
        var out = '';
        for (var i = 0; i < input.length; i++) {
            out = input.charAt(i) + out;
        }
        if (uppercase) {
            out = out.toUpperCase();
        }
        return out;
    }
});

and from the html using the template we can call that filter like below

<h1>{{inputString| reverse:true }}</h1>

here if you see , the first parameter is inputString and second parameter is true which is combined with "reverse' using the : symbol
