ons-lazy-repeat error in OnsenUI 2

Евгений Гедройц

I used previous version and was ok. Example for jQuery from https://onsen.io/guide/overview.html#UsingLazyRepeat
but now it is retrieving error:

@Евгений-Гедройц Are you using jQuery or AngularJS? The error is for Angular but you are mentioning jQuery. Also, could you post your code preferably in a codepen?

Евгений Гедройц

Yes, my project has angular and jQuery. i’m using this code:

<ons-list>
    <ons-list-item modifier="chevron" class="list_respeak" ons-lazy-repeat="MyDelegate" style="height:40px">
    </ons-list-item>
</ons-list>
			<script>
				var hItem = 40;
				
				var MyDelegate = {		  
					createItemContent: function(index, oldContent) {
					  if (oldContent) {
						return oldContent;
					  }

					  var $element = $("<div><span style='opacity: 0.7;'><ons-icon icon='fa-spinner' spin='true'></ons-icon> Загрузка респиков...</span></div>");

					  var request = $.getJSON('https://baconipsum.com/api/?type=meat-and-filler&sentences=1&callback=?', function(data) {
						$element.text(data[0]);
					  });

					  $element.data('request', request);
					  return $element[0];
					},
					destroyItemContent: function(index, element) {
					  var request = $element.data('request');
					  request.abort();
					},
					calculateItemHeight: function(index) {return hItem;},
					countItems: function(){
						return 10000000;
					},
					destroyItemContent: function(index, element) {
						 console.log("Destroyed item " + index);
					}
				}
				
				
				//$('.list_respeak').children('.ng-scope').each(function(){
					//console.log($(this).height);
					//if( $(this).height > hItem ){
						//$(this).addClass('overflow');
					//}
				//});
			</script>

In Monaca is good(OnsenUI1) I exported my project to my localhost and changed OnsenUI2
If it’s not enough i’ll make codepan

@Евгений-Гедройц If you can make a codepen, I will play with it and try to figure out what is going on. Also, avoid using the script tag in code blocks because it makes everything faded out. @Leonardo-Augusto and I learned this the hard way. :smiley:
