AngularJS渲染 为文本而不是换行符

我敢肯定这已经被问过了，但是我找不到答案。

我有一个从数据库中提取然后呈现到内容的AngularJS脚本。一切工作正常，除了我试图将一些单词用它们之间的新行连接起来的几个地方。

 **in the script.js**
groupedList[aIndex].CATEGORY = existingCategory+'\n'+thisCategory;
groupedList[aIndex].CATEGORY = existingCategory+'<br>'+thisCategory;

如果我使用上述代码的第一行，则看不到任何内容，但重新标记的html中没有新行。如果使用第二行，则将其<br>渲染为文本，并且输出如下所示：

Instinct<br>Media

代替

Instinct
Media

如果有帮助，我可以发布完整的脚本，但是我想我只是看不到一些简单的东西。

这里是完整的js

function qCtrl($scope, $filter, $http, $timeout){
    $scope.getCategories = function(){$http.post('quote.cfc?method=getCategories').success(function(data) { $scope.categories = data; });   }
    $scope.getClassifications = function(){$http.post('quote.cfc?method=getClassifications').success(function(data) {   $scope.classifications = data;  }); }
    $scope.getIndustries = function(){$http.post('quote.cfc?method=getIndustries').success(function(data) { $scope.industries = data;   }); }
    $scope.getKeywords = function(){$http.post('quote.cfc?method=getKeywords').success(function(data) { $scope.keywords = data; }); }
    $scope.getSources = function(){$http.post('quote.cfc?method=getSources').success(function(data) {   $scope.sources = data;  }); }
    $scope.getAllQuotes = function(){$http.post('quote.cfc?method=getAllQuotesJoined').success(function(data) { $scope.allQuotes = data;    }); }
    $scope.initScopes = function (){
        $scope.getCategories();
        $scope.getClassifications();
        $scope.getIndustries();
        $scope.getKeywords();
        $scope.getSources();
        $scope.getAllQuotes();
    }   
    $scope.initScopes();
    // SEARCH QUOTES
    $scope.filteredQuotes = $scope.allQuotes;
    $scope.search = {searchField:''};
    $scope.searchQuote = function(){
        var filter = $filter('filter');
        var searchCrit = $scope.search;
        var newlist = $scope.allQuotes;
        var groupedList = [];
        var idList = [];
        newlist = filter(newlist,{TESTQUOTE:searchCrit.searchField});
        for(i=0;i<10;i++){
            aIndex = idList.contains(newlist[i].TESTIMONIALID);
            if(aIndex >= 0){
                thisKeyword = newlist[i].KEYWORD;
                thisClassification = newlist[i].CLASSIFICATION;
                thisCategory = newlist[i].CATEGORY;
                existingKeyword = groupedList[aIndex].KEYWORD;
                existingClassification = groupedList[aIndex].CLASSIFICATION;
                existingCategory = groupedList[aIndex].CATEGORY;
                if(thisKeyword != '' && existingKeyword.indexOf(thisKeyword) == -1){
                    groupedList[aIndex].KEYWORD = existingKeyword+' - '+thisKeyword;
                } 
                if(thisClassification != '' && existingClassification.indexOf(thisClassification) == -1){
                    groupedList[aIndex].CLASSIFICATION = existingClassification+' \n '+thisClassification;
                } 
                if(thisCategory != '' && existingCategory.indexOf(thisCategory) == -1){
                    groupedList[aIndex].CATEGORY = existingCategory+'<br>'+thisCategory;
                }               
            } else {
                idList.push(newlist[i].TESTIMONIALID);
                groupedList.push(newlist[i]);
            }
        }
        $scope.filteredQuotes = groupedList;
      }
}
Array.prototype.contains = function ( needle ) {
   for (j in this) {
       if (this[j] == needle) return j;
   }
   return -1;
}

这是HTML

<div ng-repeat="q in filteredQuotes" class="well clearfix">
                        <h3>{{q.TITLE}}</h3>
                        <div class="row-fluid" style="margin-bottom:5px;">
                            <div class="span3 well-small whBG"><h4>Classification</h4>{{q.CLASSIFICATION}}</div>
                            <div class="span3 well-small whBG pipeHolder"><h4>Categories</h4>{{q.CATEGORY}}</div>
                            <div class="span3 well-small whBG"><h4>Key Words</h4>{{q.KEYWORD}}</div>
                            <div class="span3 well-small whBG"><h4>Additional</h4>Industry = {{q.INDUSTRY}}<br>Source = {{q.SOURCE}}</div>
                        </div>
                        <div class="well whBG">{{q.TESTQUOTE}}</div>
                        <div class="tiny">
                            Source comment : {{q.SOURCECOMMENT}}<br>
                            Additional Comment : {{q.COMMENT}}
                        </div>
                    </div>
                </div>

回答：

我可能是错的，因为我从未使用过Angular，但是我相信您可能正在使用ng-bind，它只会创建一个TextNode。

您将要使用ng-bind-html代替。

http://docs.angularjs.org/api/ngSanitize.directive:ngBindHtml

：看来您需要使用ng-bind-html-unsafe='q.category'

http://docs.angularjs.org/api/ng.directive:ngBindHtml不安全

这是一个演示：
