Format percentages in AngularJS

percent-filter.js

// In app.js or main.js or whatever:
// var myApp = angular.module('askchisne', ['ngSanitize', 'ngAnimate', 'ui.bootstrap', 'ui.bootstrap.tpls']);

// This filter makes the assumption that the input will be in decimal form (i.e. 17% is 0.17).
myApp.filter('percentage', ['$filter', function ($filter) {
  return function (input, decimals) {
    return $filter('number')(input * 100, decimals) + '%';
  };
}]);

// Usage:
<tr ng-repeat="i in items">
  <td>{{i.statistic | percentage:2}}</td>
</tr>

Works great!

👍 🚀

Thanks!

If I wanted to put this inline as in:

cellFilter: $filter(''number')(input * 100, decimals) + '%';

... if I put it inline, what would I put instead of 'input'? I am getting an error this way, & trying to inject the custom filter is not working for me right now for some reason.

thanks for sharing this. 👍

thanks for working example

@jeffjohnson9046 In my project I have the same code what you have posted above , I confused on the
return function (input, decimals) { return $filter('number')(input * 100, decimals) + '%'; };
My question , where is the data comes from input , for my case in my jade like this
td(style='text-align: right', ng-show='view.showHistory') span(ng-bind='x.recentScore | percentage:0') trend-arrow(b='x.pastScore', a='x.recentScore')

I dont get any Clue where they assigned input value ? Please guide me.

Thanks!

thanks!

Thanks for this.

Awesome! How do you apply this to an input tag though? I only need to put a '%' suffix in the input but read the numeric value in the model?

Thank you!

Works like charm...
Thanks!!!

i need to add decimal point with dot (.) or comma (,) separator.how could anyone find a way to solve the problem.

Useful, thanks!

Awesome, thanks!

Thanks

@LahiruDhananjaya, you only have to use i18n and l10n.

nice.
Adding a check for the decimal and default it to 2 is a better addition. In most cases, percentages are represented in 2 decimals.

myApp.filter('percentage', ['$filter', function ($filter) { return function (input, decimals) { if (typeof decimals === "undefined") { decimals = 2; } return $filter('number')(input * 100, decimals) + '%'; }; }]);

This solution taught me what i need to know about pipes AKA filters. Jeez!!
