Codice

HTML: codice

<table class="table" ng-table="tableParams" show-filter="false" ng-class="{loadingtable : loading}" ng-show="showResults"> 
       <tbody> 
        <tr ng-repeat="asset in assets"> 
         <td class="col-md-4" data-title="'Serial Number'" header-class="text-left" search-word-marker param="{{asset.sn}}"></td> 
         <td class="col-md-4" data-title="'Asset Name'" accesskey="" header-class="text-left" search-word-marker param="{{asset.asset_name}}"></td> 
         <td class="col-md-2" data-title="'Asset Type'" header-class="text-left">{{asset.asset_type}}</td> 
         <td class="col-md-2" data-title="'Tags'" header-class="text-left">{{asset.tags}}</td> 
         <td class="col-md-1"> 
          <div class="btn-group"> 
           <span> 
            <button type="button" class="btn btn-sm btn-primary" ng-click="viewAsset(asset.sn);">{{'VIEW' | translate}}</button> 
           </span> 
          </div> 
         </td> 
        </tr> 
       </tbody> 
      </table> 

DIRETTIVA:

Application.Directives.directive('searchWordMarker', ['$log', '$rootScope', function ($log, $rootScope) { 
    return { 
     restrict: 'A', 
     scope: { 
      param: '=' 
     }, 
     //template: "{{myNewString}}", 
     //replace: false, 
     link: function (scope, el, attr) { 

      var myString = attr.param; 

      var searchWord = $rootScope.searchWord; 

      var regex = new RegExp(searchWord, "g"); 
      var myNewString = myString.replace(regex, "<B>" + searchWord + "</B>"); 


      el[0].innerHTML = myNewString; 


     } 
    } 
}]); 

Answer 1

Stai cercando di fare un attacco a 2 vie (param : "=") per ciò che è scritto nel param, ma che non è un oggetto o una variabile, è un'espressione. O perdere il {{}} o cambiare la tua scope.param vincolante di essere in una stringa:

scope: { 
    param: '@' 
},
