angularjs - Ng-cloak interferes with directive that measures a block dimensions -


i go straight code description.

the directive measures height of block.

<script type="text/javascript"> var rootapp = angular.module('rootapp');  // directive log height. have add on value final height, because css style undefined.  rootapp.directive('logheight', ['$timeout', function($timeout) {     return {         restrict: 'a',         link: function(scope, element) {             scope.prepmaxheight = element.prop('offsetheight');             scope.value = 0;             $timeout(function() {                 scope.maxheight = scope.value + scope.prepmaxheight;             }, 0);         }     }; }]); </script>

the scope value , directive applied html div. gives current height of div, applied same div style="max-height: {{'{{maxheightcat}}'}}px;". goal have precise height of block animation purpose.

<md-button ng-href="#" ng-click="showaccordion = ! showaccordion" md-no-ink>    <span>         accordion button    </span> </md-button>  <div class="accordion-wrapper" ng-class="{ 'hidden': ! showaccordion }" log-height style="max-height: {{maxheight}}px;">     <div class="accordion-inner-wrapper" ng-class="{ 'animate': showaccordion }">         <ul>           <li>item 1</li>           <li>item 2</li>           <li>item 3</li>           <li>item 4</li>        </ul>    </div> </div>

the problem flickering effect. angular recommend ng-cloak, helps, breaks directive logheight.

added ng-cloak flickering block.

<div class="accordion-wrapper" ng-class="{ 'hidden': ! showaccordion }" log-height style="max-height: {{maxheight}}px;" ng-cloak>     <div class="accordion-inner-wrapper" ng-class="{ 'animate': showaccordion }">         <ul>           <li>item 1</li>           <li>item 2</li>           <li>item 3</li>           <li>item 4</li>        </ul>    </div> </div>

with no ng-cloak declared div, gives me needed height. it, 0px. $timeout didn't help. may be, ng-cloak directive compiled , injected dom last?
