javascript - Angular UI-Grid customTemplate directive causing rows to load slowly/? -


each grid cell can have more 1 customtemplate loaded. have directive holds watcher on model_col_field listen cell updates on scroll when dom rows updated , recompile celltemplate. without watcher , $compile rows repeat on scroll, showing same set of rows.

is there more angular way of approaching or way improve performance?

relevant controller code: create gridoptions.data & gridoptions.columndefs:

  var customtemp = '<div ng-repeat="opt in grid.appscope.colvalueoptionsmodel" ng-init="tempstring=model_col_field.clazz+opt.key;"><comparison-directive dbo="model_col_field" attobj="opt" fff="grid.appscope.getattributetemplate(tempstring)" /></div>';        $scope.gridoptions.columndefs = [           { name:'yindex',pinnedleft:true,celltemplate: customtemp, displayname:'index'},           { name:'col1',celltemplate: customtemp},           { name:'col2',celltemplate: customtemp},...       ];

ui-grid celltemplate directive:

    app.directive('comparisondirective', function ($log, $compile) {     return {         restrict: 'e',         replace: true,         scope: {           dbo:'=',           attobj:'=',           fff:'&'         },         template: '<div ng-init="key = attobj.key;values=dbo.get4(attobj.key); template = attobj.template || fff(tempstring);"><div class="contentdecompressed" customtemp></div></div>',         link: function (scope, element, attrs) {              scope.$watch('dbo', function(newvalue, oldvalue) {               if(newvalue !== oldvalue){                   element.html('<div ng-init="key = attobj.key;values=dbo.get4(attobj.key); template = attobj.template || fff(tempstring);"><div class="contentdecompressed" customtemp></div></div>');                   $compile(element.contents())(scope);               }                        });         }     }; });

directive each template loaded inside each grid cell:-

    app.directive('customtemp', function($templatecache, $compile) {    return {        link: function(scope, element, attrs) {             // console.log(scope.template)             element.html($templatecache.get(scope.template));             $compile(element.contents())(scope);        }    } });
