如何使用HTML内容创建AngularJS UI引导程序弹出窗口？

Question

我想创建一个带有pre标签的bootstrap popover,其中包含一个美化的JSON对象.天真的实施,

<span popover='<pre>{[ some_obj | json:"  " ]}</pre>'
      popover-trigger='mouseenter'>

在将内容插入弹出窗口之前将其转义.使用html内容指定弹出框体的最佳方法是什么？

Answer 1

更新:

如可以在被看见这个,你现在应该能够做到这一点没有覆盖缺省模板.

原版的:

至于角度1.2+ ng-bind-html-unsafe已被删除.你应该使用$ sce服务.参考.

这是一个用于创建可信html的过滤器.

MyApp.filter('unsafe', ['$sce', function ($sce) {
    return function (val) {
        return $sce.trustAsHtml(val);
    };
}]);

这是使用此过滤器覆盖的Angular Bootstrap 0.11.2模板

// update popover template for binding unsafe html
angular.module("template/popover/popover.html", []).run(["$templateCache", function ($templateCache) {
    $templateCache.put("template/popover/popover.html",
      "<div class=\"popover {{placement}}\" ng-class=\"{ in: isOpen(), fade: animation() }\">\n" +
      "  <div class=\"arrow\"></div>\n" +
      "\n" +
      "  <div class=\"popover-inner\">\n" +
      "      <h3 class=\"popover-title\" ng-bind-html=\"title | unsafe\" ng-show=\"title\"></h3>\n" +
      "      <div class=\"popover-content\"ng-bind-html=\"content | unsafe\"></div>\n" +
      "  </div>\n" +
      "</div>\n" +
      "");
}]);

编辑:这是一个Plunker实现.

编辑2:由于这个答案不断得到点击,我会尽可能地保持更新.作为参考这是angular-ui bootstrap repo的模板.如果更改,则覆盖模板将需要匹配更新并添加ng-bind-html=\"title | unsafe\"和ng-bind-html=\"content | unsafe\"属性以继续工作.

对于更新的谈话检查这里的问题.

使用popover-template指令

如果您使用的角度ui等于或高于0.13.0,则最佳选择是使用该popover-template指令.以下是如何使用它:

<button popover-template="'popover.html'">My HTML popover</button>

<script type="text/ng-template" id="popover.html">
    <div>
        Popover content
    </div>
</script>

注意:不要忘记模板名称周围的引号popover-template="'popover.html'".

见demo plunker

作为旁注,可以将popover模板外部化为专用的html文件,而不是<script type="text/ng-template>像上面那样在元素中声明它.

请参阅第二个演示plunker

我在github项目上发布了一个解决方案:https://github.com/angular-ui/bootstrap/issues/520

我想将此功能添加到您的项目中,这是一个补丁.

添加这些指令:

angular.module("XXX")
    .directive("popoverHtmlUnsafePopup", function () {
      return {
        restrict: "EA",
        replace: true,
        scope: { title: "@", content: "@", placement: "@", animation: "&", isOpen: "&" },
        templateUrl: "template/popover/popover-html-unsafe-popup.html"
      };
    })

    .directive("popoverHtmlUnsafe", [ "$tooltip", function ($tooltip) {
      return $tooltip("popoverHtmlUnsafe", "popover", "click");
    }]);

并添加模板:

<div class="popover {{placement}}" ng-class="{ in: isOpen(), fade: animation() }">
  <div class="arrow"></div>

  <div class="popover-inner">
      <h3 class="popover-title" ng-bind="title" ng-show="title"></h3>
      <div class="popover-content" bind-html-unsafe="content"></div>
  </div>
</div>

用法: <button popover-placement="top" popover-html-unsafe="On the <b>Top!</b>" class="btn btn-default">Top</button>

Answer 4

您需要更改默认弹出框模板以指定您要允许Html内容.看看popover-contentdiv,它现在已经对content属性进行了绑定,允许不安全的html:

 angular.module("template/popover/popover.html", []).run(["$templateCache", function ($templateCache) {
        $templateCache.put("template/popover/popover.html",
            "<div class='popover {{placement}}' ng-class='{ in: isOpen(), fade: animation() }'>" + 
            "<div class='arrow'></div><div class='popover-inner'>" + 
            "<h3 class='popover-title' ng-bind='title' ng-show='title'></h3>" + 
            "<div class='popover-content' ng-bind-html-unsafe='content'></div>" +
            "<button class='btn btn-cancel' ng-click='manualHide()'>Cancel</button>" +
            "<button class='btn btn-apply' ng-click='manualHide()'>Apply</button></div></div>");
    }]);

对于所有传统的Bootstrap popover需求,您可以使用以下角度指令.它可以消除HTML模板中的混乱,并且非常易于使用.

您可以配置酥料饼的title,content,placement,淡入/淡出delay,trigger事件和内容是否应被视为html.它还可以防止内容溢出和剪切.

用法

<!-- HTML -->
<div ng-model="popup.content" popup="popup.options">Some element</div>

/* JavaScript */
this.popup = {
  content: 'Popup content here',
  options: {
    title: null,
    placement: 'right', 
    delay: { show: 800, hide: 100 }
  }
}; 

JavaScript的

/**
 * Popup, a Bootstrap popover wrapper.
 *
 * Usage: 
 *  <div ng-model="model" popup="options"></div>
 * 
 * Remarks: 
 *  To prevent content overflow and clipping, use CSS
 *  .popover { word-wrap: break-word; }
 *  Popup without title and content will not be shown.
 *
 * @param {String}  ngModel           popup content
 * @param {Object}  options           popup options
 * @param {String}  options.title     title
 * @param {Boolean} options.html      content should be treated as html markup
 * @param {String}  options.placement placement (top, bottom, left or right)
 * @param {String}  options.trigger   trigger event, default is hover
 * @param {Object}  options.delay     milliseconds or { show:<ms>, hide:<ms> }

app.directive('popup', function() {
  return {
    restrict: 'A',
    require: 'ngModel',
    scope: {
      ngModel: '=',
      options: '=popup'
    },
    link: function(scope, element) {
      scope.$watch('ngModel', function(val) {
        element.attr('data-content', val);
      });

      var options = scope.options || {} ; 

      var title = options.title || null;
      var placement = options.placement || 'right';
      var html = options.html || false;
      var delay = options.delay ? angular.toJson(options.delay) : null;
      var trigger = options.trigger || 'hover';

      element.attr('title', title);
      element.attr('data-placement', placement);
