如何在angularjs中显示表情符号unicode字符？

Question

我有 JSON 中的 emoji unicode 列表，角度绑定未将&#x{{emoji.unicode}}; html 中的 unicode 显示为符号

(function() {
  var app = angular.module('tableApp', []);
  app.controller('tableController', function($scope) {
    $scope.emojis = [{
      "unicode": "1f600",
      "unicode_alternates": "",

表情符号可以显示为trustAsHtml()。在这里我们可以使用 in 过滤器。

.filter('exposeEmoji', function($sce) {
    return function(val) {
        val = "&#x"+ val + ";";
        return $sce.trustAsHtml(val);
    };
});

(function() {
  var app = angular.module('tableApp', []);
  app.controller('tableController', function($scope) {
    $scope.emojis = [{
      "unicode": "1f600",
      "unicode_alternates": "",
      "name": "grinning face",
      "shortname": ":grinning:",
      "category": "people",
      "emoji_order": "1",
      "aliases": [],
      "aliases_ascii": [],
      "keywords": ["happy", "joy", "smile", "grin", "smiling", "smiley", "person"]
    }, {
      "unicode": "1f62c",
      "unicode_alternates": "",
      "name": "grimacing face",
      "shortname": ":grimacing:",
      "category": "people",

      "aliases": [],
