AngularJS 正在渲染 <br>作为文本而不是换行符 [英] AngularJS is rendering <br> as text not as a newline
问题描述
我确定以前有人问过这个问题,但我找不到答案.
我有一个 AngularJS 脚本,它从数据库中提取然后渲染到内容.除了几个地方我试图用新行在它们之间连接一些单词之外,一切都正常工作.
**在 script.js 中**groupedList[aIndex].CATEGORY = existingCategory+'\n'+thisCategory;groupedList[aIndex].CATEGORY = existingCategory+'
'+thisCategory;
如果我使用上面代码的第一行,我什么也看不到,但在重新编写的 html 中没有新行.如果我使用第二行,<br>
将呈现为文本,输出如下所示:
Instinct
媒体
代替
本能媒体
如果有帮助的话,我可以发布完整的脚本,但我猜有一些我没有看到的简单内容.
更新这是完整的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 = 函数 (){$scope.getCategories();$scope.getClassifications();$scope.getIndustries();$scope.getKeywords();$scope.getSources();$scope.getAllQuotes();}$scope.initScopes();//搜索报价$scope.filteredQuotes = $scope.allQuotes;$scope.search = {searchField:''};$scope.searchQuote = function(){var filter = $filter('filter');var searchCrit = $scope.search;var newlist = $scope.allQuotes;var groupedList = [];var idList = [];newlist = filter(newlist,{TESTQUOTE:searchCrit.searchField});for(i=0;i<10;i++){aIndex = idList.contains(newlist[i].TESTIMONIALID);if(aIndex >= 0){thisKeyword = newlist[i].KEYWORD;thisClassification = newlist[i].CLASSIFICATION;thisCategory = newlist[i].CATEGORY;existingKeyword = groupedList[aIndex].KEYWORD;existingClassification = groupedList[aIndex].CLASSIFICATION;existingCategory = groupedList[aIndex].CATEGORY;if(thisKeyword != '' && existingKeyword.indexOf(thisKeyword) == -1){groupedList[aIndex].KEYWORD = existingKeyword+' - '+thisKeyword;}if(thisClassification != '' && existingClassification.indexOf(thisClassification) == -1){groupedList[aIndex].CLASSIFICATION = existingClassification+' \n '+thisClassification;}if(thisCategory != '' && existingCategory.indexOf(thisCategory) == -1){groupedList[aIndex].CATEGORY = existingCategory+'
'+thisCategory;}} 别的 {idList.push(newlist[i].TESTIMONIALID);groupedList.push(newlist[i]);}}$scope.filteredQuotes = groupedList;}}Array.prototype.contains = 函数(针){for (j 在这) {如果 (this[j] == 针) 返回 j;}返回-1;}
这是 HTML
<h3>{{q.TITLE}}</h3><div class="row-fluid" style="margin-bottom:5px;"><div class="span3 well-small whBG"><h4>分类</h4>{{q.CLASSIFICATION}}</div><div class="span3 well-small whBG pipeHolder"><h4>Categories</h4>{{q.CATEGORY}}</div><div class="span3 well-small whBG"><h4>关键词</h4>{{q.KEYWORD}}</div><div class="span3 well-small whBG"><h4>Additional</h4>Industry = {{q.INDUSTRY}}<br>Source = {{q.SOURCE}}</div><div class="well whBG">{{q.TESTQUOTE}}</div><div class="tiny">来源评论:{{q.SOURCECOMMENT}}

我可能是错的,因为我从未使用过 Angular,但我相信你可能正在使用 ng-bind
,它会创建只是一个 TextNode.
您将要使用 ng-bind-html
代替.
http://docs.angularjs.org/api/ngSanitize.directive:ngBindHtml>
更新:您似乎需要使用 ng-bind-html-unsafe='q.category'
http://docs.angularjs.org/api/ng.directive:ngBindHtmlUnsafe>
这是一个演示:
I am sure this has been asked before but I cannot find the answer.
I have an AngularJS script that is pulling from a DB and then rendering to content. Everything is working correctly except a couple of places that I am trying to concatenate some words with new lines between them.
**in the script.js**
groupedList[aIndex].CATEGORY = existingCategory+'\n'+thisCategory;
groupedList[aIndex].CATEGORY = existingCategory+'<br>'+thisCategory;
If I use the first line of the above code I don't see anything but there is not a new line in the redered html. If I use the second line the <br>
get rendered as text and the output looks like this:
Instinct<br>Media
instead of
Instinct
Media
I can post the full script if that would be helpful but I am guessing there is something simple that I am just not seeing.
UPDATE Here is the full 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;
}
Here is the HTML
<div ng-repeat="q in filteredQuotes" class="well clearfix">

I could be wrong because I've never used Angular, but I believe you are probably using ng-bind
, which will create just a TextNode.
You will want to use ng-bind-html
instead.
http://docs.angularjs.org/api/ngSanitize.directive:ngBindHtml
Update: It looks like you'll need to use ng-bind-html-unsafe='q.category'
