我正在使用ng-repeat指令在我的离子应用程序中显示一个巨大的列表,最近切换到集合重复。然而,收集重复列表变得很短,并没有显示所有数组项。在代码中我只将集合重复更改为ng-repeat,它的工作方式与预期一致。顺便说一下,我试图在指令定义中使用它,这是一个angucomplete,在指令中我自定义过滤数据,这里是相关的html和js:
'<div class="angucomplete-holder">'+
'<input id="{{id}}_value" ng-model="searchStr" type="text" placeholder="{{placeholder}}" class="{{inputClass}}" onmouseup="this.select();" ng-focus="resetHideResults()" />'+
'<ion-scroll direction="y" id="{{id}}_dropdown" class="angucomplete-dropdown" ng-if="showDropdown">'+
'<div class="angucomplete-searching" ng-show="searching">Searching...</div>'+
'<div class="angucomplete-searching" ng-show="!searching && (!results || results.length == 0)">No results found</div>'+
'<div class="angucomplete-searching" ng-show="!searching && (!results || results.length == 0)">{{noResultMsg}}</div>'+
'<div class="angucomplete-searching" ng-show="!searching && (!results || results.length == 0)"><img src="img/title_icon.png" style="width:30px;height:30px;"/></div>'+
'<div class="angucomplete-row" collection-repeat="result in results track by $index" ng-mousedown="selectResult(result)" ng-class="{\'angucomplete-selected-row\': $index == currentIndex}">'+
'<div ng-if="imageField" class="angucomplete-image-holder">'+
'<img ng-if="result.image && result.image != \'\'" ng-src="{{result.image}}" class="angucomplete-image"/>'+
'<div ng-if="!result.image && result.image != \'\'" class="angucomplete-image-default"></div>'+
'</div>'+
'<div class="angucomplete-title" ng-if="matchClass" ng-bind-html="result.title"></div>'+
'<div class="angucomplete-title" ng-if="!matchClass">{{ result.title }}</div>'+
'<div ng-if="result.description && result.description != \'\'" class="angucomplete-description">{{result.description}}</div>'+
'</div>'+
'</ion-scroll>'+
'</div>',
