AngularJS + Json：如何呈现html

Question

(I know this question was asked many times, but I believe my setup is different and so a new question needed to be asked with a different scenario)

There are plenty of examples out there that shows how to Render HTML, but I can't seem to get this to work with any of the examples. I'd like to render html the {{aboutlongs[0].description}} (this has <br /> tags that I would like to render as html)

Here's the js:

App.controller('aboutLongCtrl', function ($scope, $http) {
    $http.get('test_data/ar_org.json')
        .then(function (res) {
            $scope.aboutlongs = res.data.aboutlong;
        });
});

the HTML:

<div class="background-white p20 reasons" ng-controller="aboutLongCtrl" >
    <h6><b>About {{aboutlongs[0].name}}</b></h6>
    <div class="reason-content" >
       {{aboutlongs[0].description}}
    </div>
</div>

Can anyone point me to the right direction?

The Json file:

"aboutlong": [{
        "name": "Women's March",
        "description": "The rhetoric of the past election cycle has insulted, demonized, and threatened many of us - immigrants of all statuses, Muslims and those of diverse religious faiths, people who identify as LGBTQIA, Native people, Black and Brown people, people with disabilities, survivors of sexual assault - and our communities are hurting and scared. We are confronted with the question of how to move forward in the face of national and international concern and fear.<br /><br />In the spirit of democracy and honoring the champions of human rights, dignity, and justice who have come before us, we join in diversity to show our presence in numbers too great to ignore. The Women's March on Washington will send a bold message to our new government on their first day in office, and to the world that women's rights are human rights. We stand together, recognizing that defending the most marginalized among us is defending all of us.<br /><br />We support the advocacy and resistance movements that reflect our multiple and intersecting identities. We call on all defenders of human rights to join us. This march is the first step towards unifying our communities, grounded in new relationships, to create change from the grassroots level up. We will not rest until women have parity and equity at all levels of leadership in society. We work peacefully while recognizing there is no true peace without justice and equity for all.<br /><br />Women's rights are human rights, regardless of a woman's race, ethnicity, religion, immigration status, sexual identity, gender expression, economic status, age or disability. We practice empathy with the intent to learn about the intersecting identities of each other. We will suspend our first judgement and do our best to lead without ego."

Answer 1

if you want to render string to html i recommand to use $sce.trustAsHtml(html) .

you can create a sample filter like this

.filter('trustHtml',function($sce){
  return function(html){
    return $sce.trustAsHtml(html)
  }
})

call the filter like this inside ng-bind-html

<div class="reason-content" ng-bind-html="aboutlongs[0].description | trustHtml" ></div>

Demo

 angular.module("app",[]) .controller("ctrl",function($scope){ $scope.aboutlongs = [{ "name": "Women's March", "description": "The rhetoric of the past election cycle has insulted, demonized, and threatened many of us - immigrants of all statuses, Muslims and those of diverse religious faiths, people who identify as LGBTQIA, Native people, Black and Brown people, people with disabilities, survivors of sexual assault - and our communities are hurting and scared.
