对于angular，要在具有属性名称连字符的模板中呈现表达式，必须使用括号而不是点。示例docs [“paragraph-content”]而不是docs.paragraph-content。我试图在ng-bind-html-unsafe中打印此变量，如ng-bind-html-unsafe =“doc [”paragraph-content“]”在我的指令模板中，但是我收到语法错误，错误：语法错误：Token'undefined'不是从[doc []开始的表达式[doc []的列NaN处的主表达式。
template: '<div>' +
'<input ng-model="query" placeholder="Check your face" name="Search"></input>' +
'<h2 id="search-list-title" class="list-header-title">Search Results for {{query}}</h2>' +
'<form id="search-list-form" class="list-row list-form" ng-repeat="doc in results.docs">' +
' <a id="search-item-title" class="list-element list-title" href="retrieve-graph?id={{doc.id}}"><p>{{doc["paragraph-subject"]}}</p></a>' +
' <p id="search-item-content" class= "list-element list-content" ng-bind-html-unsafe="doc["paragraph-content"]"></p>' +
' <p id="search-item-id" class= "list-email list-element">{{doc["user-email"]}}</p>' +
' <!--<p>{{doc.title}}</p>-->' +
' <!--urls point to user paragraph list and goes to specific paragraph through anchor link' +
' <!--Need to create form that inserts id as parameter so can query and display on template page <p><a target="_blank" href="{{doc.id}}"> {{doc.url}}</a></p>-->' +
' <br>'+
'</form>'+
'</div>'
