如何在ng-repeat中增加init变量值
<div ng-if="FeedData.carouselMode == true" ng-init='start=0' ng-repeat="a in carousel_data"> <div class="owl-demo" class="owl-carousel" owl-carousel > <div class="item" ng-repeat="(key,item) in a.carouselFeeds" ng-init="start=start+1"> {{start}} <div ng-click="go('{{key}}',item.FeedUrls.length,'rtl')" ng-swipe-left="go('{{key}}','rtl')"> <img class="lazyOwl" ng-src="{{item.img}}" /> <span class="innersquare" image-ja="{{item.img}}"> <p ng-style="folderStyle">{{item.name }} </p> </span> </div> </div> </div> </div>
增量开始后ng-init start = 0 = ng-repeat中的start 1但没有count只显示1.
这是因为每个ng-repeat都有自己的范围,每个ng-init只会增加自己的范围变量.您可以尝试使用$parent访问父作用域.

<div ng-controller="MyCtrl">
<div ng-repeat="a in ['a','b','c']" ng-init="current = $parent.start; $parent.start=$parent.start+3;">
<div ng-repeat="x in ['alpha','beta','gamma']">
{{current + $index}}
</div>
</div>
3应该是[内部阵列的长度].

对于您的特定代码,它看起来像这样
<div ng-if="FeedData.carouselMode == true" ng-init='current=$parent.start; $parent.start=$parent.start+a.carouselFeeds.length' ng-repeat="a in carousel_data"> <div class="owl-demo" class="owl-carousel" owl-carousel> <div class="item" ng-repeat="(key,item) in a.carouselFeeds"> {{current + $index}} <div ng-click="go('{{key}}','rtl')"> <img class="lazyOwl" ng-src="{{item.img}}" /> <span class="innersquare" image-ja="{{item.img}}"> <p ng-style="folderStyle">{{item.name }} </p> </span> </div> </div> </div> </div>
