添加angularjs后Salvattore网格停止工作

Question

When I added angularjs to my project, Salvattore grid stopped working, it's not rendering.

I want to use ng-repeat functionality to loop through all the items and display them in Salvattore grid.

What can cause this? Thanks

Ok looks like what's happening is, Salvattore assumes that the elements it needs to apply masonry layouts are present in the dom by the time you add data-columns attribute and of course this wont work because ng-repeat takes a digest cycle to add the elements to dom.

One way to get around this is to create a custom directive that would initialise data-columns after elements are present in dom.

One quick way (probably not the most robust) would be to add that data-columns attribute after a digest cycle.

Here's an implementation:

 var app = angular.module('app', []); app.controller('grid', function($scope) { $scope.data = [ 'test1','test2','test3','test4', 'test5','test6','test7' ]; }); app.directive('salvattore', function($timeout, $window) { return { restrict: 'A', link: function(scope, element, attrs) { $timeout(function(){ //Hack to execute on next timeout element.attr('data-columns', true); $window.salvattore.register_grid(element[0]); },0); } }; }); 

 .grid[data-columns]::before { content: '3 .col-4'; } .grid { margin-bottom:50px; }

Here's the directive:

app.directive('salvattore', function($timeout, $window) {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {
      $timeout(function(){ //Hack to execute on next timeout
        element.attr('data-columns', true);
        $window.salvattore.register_grid(element[0]);            
      },0);
    }
  };

});

Note: The directive is inspired by https://github.com/nathankot/angular-salvattore

我添加了Chanthu编写的指令（以及html中的attr），并且ng-if="array.length>0"对我ng-if="array.length>0" 。
