javascript - AngularJS textarea newline on enter key -

-

i developing angularjs application same how post answers , questions on stackoverflow , live preview of our answers or question below textarea.

here trial code:

index.html-

<div ng-app="bindhtmlexample" ng-controller="examplecontroller">         <textarea ng-model="myhtml"></textarea>         <div ng-bind-html="myhtml"></div> </div>

script.js-

(function(angular) {   'use strict'; angular.module('bindhtmlexample', ['ngsanitize'])   .controller('examplecontroller', ['$scope', function($scope) {     $scope.myhtml =        'i <code>html</code>string ' +        '<a href="#">links!</a> , other <em>stuff</em>';   }]); })(window.angular);

when user types in textarea, user can see live preview of he/she typing in <div ng-bind-html="myhtml"></div>. when user types html code, show real html output.

i have done upto this.

so, problem when user presses enter key in textarea, newline must started in <div ng-bind-html="myhtml"></div>.

how do that?

here screenshot of wordpress website, idea want...

thats because newlines in textarea not html line breaks. need replace them this:

$(document).ready(function() {    var pad = $('#pad');    var board = $('#board');      pad.keypress(function(event) {      board.html(pad.val().replace(/\r?\n/g, '<br />'));    });  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <textarea id="pad"></textarea>  <div id="board"></div>
