Angular ng-hide在指令中不起作用

Question

return {
restrict : "AC",
template : + '<div> '
+ '     <span class="smallFont" data-ng-hide="dossierItem.itemDetail.pubdate">{{ item.createdOn | hbdatetime }}</span>'
+ '     <span class="smallFont" data-ng-show="dossierItem.itemDetail.pubdate">{{ item.itemDetail.pubdate | hbdatetimepubdate }}</span>'
+ ' </div>',
link : function(scope, elm, attrs) {
scope.$watch(attrs.itemList, function(value) {
elm.text(value);
});
}

I can see both dates are loading in the inspect element.But it is always showing create date on the view. I am showing a detailed info while clicking on this ,if i do that it will display the correct one in both places .

But not sure why ng-hide is not working in directive .

Please suggest

Try this one.

Working Demo

Problem here you miss open div tag in template portion and make sure assign value before need to create/initialize object.

    $scope.dossierItem = {};
    $scope.dossierItem.itemDetail = {};
    $scope.dossierItem.itemDetail.pubdate = new Date();

This cause issue:

$scope.dossierItem.itemDetail.pubdate = new Date();

if not initialize dossierItem object it throws errors. Please your console error to inspect better. Few things eliminated for clarity.

var myApp = angular.module("myApp",[]);

myApp.controller("MainCtrl",function($scope){

    $scope.dossierItem = {};
    $scope.dossierItem.itemDetail = {};
    $scope.dossierItem.itemDetail.pubdate = new Date();

    $scope.validDate = true;

    $scope.item= {},
    $scope.item.createdOn = new Date();

    console.log($scope.dossierItem);
});


myApp.directive("test", function(){

return {
restrict : "AC",
template :'<div>'
    +'<span class="smallFont" ng-hide="dossierItem.itemDetail.pubdate">span1 {{item.createdOn}} </span>'
    +'<span class="smallFont" ng-show="dossierItem.itemDetail.pubdate">span2 {{item.createdOn}}</span>'
+'</div>',
}
});
