在某些其他范围对象的 ng-repeat 中使用另一个范围对象值
Using another scope object values within the ng-repeat of some other scope object
我已经设置了一个fiddle来很好地解释我的问题。我想显示 $scope.gem
中的 ng-repeat
中的名称 [每个 ng-repeat 只有一个名称,并且不要全部循环] $scope.knobItems
而不扩展 knobItems
范围。我希望通过保持控制器现在的确切结构来实现这一点。我是 angular 的新手。我只想知道这在 angular 中是否可行,是否是一个好的做法。
查看
<div ng-app="myapp">
<div ng-controller="Mycont">
<div ng-repeat="knobs in knobItems">
<div ng-repeat="(key, value) in knobItems.nums">{{value.knobTitle}} : {{value.knobColor}}
<div ng-bind="gem[0].name"></div>
</div>
</div>
</div>
</div>
控制器
var ngMod = angular.module("myapp", []);
ngMod.controller("Mycont", function ($scope) {
$scope.knobItems = {};
$scope.knobItems.nums = [{
knobTitle: "Company Profile",
knobColor: "#f46607"
}, {
knobTitle: "Deals left This Month",
knobColor: "#ffcc00"
}, {
knobTitle: "Pricelist",
knobColor: "#f40787"
}, {
knobTitle: "Pictures",
knobColor: "#a1b80a"
}, {
knobTitle: "Videos",
knobColor: "#14b9d6"
}];
$scope.gem = [{
name: "Thomas"
}, {
name: "Sebastian"
}, {
name: "June"
}, {
name: "Yuvan"
}];
});

你 fiddle 的输出与没有第一个 ng-repeat 完全相同:http://jsfiddle.net/2nrbrfxL/
根据你的描述而不是你的代码:
<div ng-app="myapp">
<div ng-controller="Mycont">
<div ng-repeat="knobs in knobItems">
<div ng-repeat="(key, value) in knobs">{{value.knobTitle}} : {{value.knobColor}}
<div ng-repeat="gemItem in gem">{{gemItem.name}}</div>
</div>
</div>
</div>
</div>
轻松修复:fiddle
<div ng-app="myapp">
<div ng-controller="Mycont">
<div ng-repeat="knobs in knobItems">
<div ng-repeat="(key, value) in knobItems.nums">{{value.knobTitle}} : {{value.knobColor}}
<div ng-bind="gem[$index].name"></div>
