我试图显示元素的二叉树,我用ng-include递归地进行.

ng-init="item = item.left"和之间有什么区别ng-repeat="item in item.left"？在这个例子中,它的行为完全相同,但我在项目中使用类似的代码,并且它的行为有所不同.我想这是因为Angular范围.也许我不应该使用ng-if,请解释我如何做得更好.

pane.html是:

<div ng-if="!isArray(item.left)">
    <div ng-repeat="item in [item.left]" ng-include="'Views/pane.html'">
    </div>
</div>
<div ng-if="isArray(item.left)">
    {{item.left[0]}}
</div>
<div ng-if="!isArray(item.right)">
    <div ng-repeat="item in [item.right]" ng-include="'Views/pane.html'">
    </div>
</div>
<div ng-if="isArray(item.right)">
    {{item.right[0]}}
</div>

<div ng-if="!isArray(item.left)">
    <div ng-init = "item = item.left" ng-include="'Views/pane.html'">
    </div>
</div>
<div ng-if="isArray(item.left)">
    {{item.left[0]}}
</div>
<div ng-if="!isArray(item.right)">
    <div ng-init="item = item.right" ng-include="'Views/pane.html'">
    </div>
</div>
<div ng-if="isArray(item.right)">
    {{item.right[0]}}
</div>

控制器是:

var app = angular.module('mycontrollers', []);

app.controller('MainCtrl', function ($scope) {

    $scope.tree = {
        left: {
            left: …
