目标：根据数据生成动态菜单，希望可以根据判断是否有子集无限循环下去。
菜单希望的样子是这样的：
菜单数据是这样的：
$scope.expanders = [{
title: 'title1',
link: 'xx/xx',
child:[
{
title: 'child2',
link: 'xx/xx'
},
{
title: 'child3',
link: 'xx/xx',
child:[
{
title: 'child5',
link: 'xx/xx'
}
]
}
]
}, {
title: 'title2',
link: 'xx/xx'
}, {
title: 'title3',
link: 'xx/xx'
}];
那么下面贴下代码，主要是用指令无限递归实现的：
1.js
var myModule = angular.module('myApp', []);
myModule.controller('TestController', ['$rootScope', '$scope', function($rootScope, $scope) {
$scope.expanders = [{
title: 'title1',
link: 'xx/xx',
child:[
{
title: 'child2',
link: 'xx/xx'
},
{
title: 'child3',
link: 'xx/xx',
child:[
{
title: 'child5',
link: 'xx/xx'
}
]
}
]
}, {
title: 'title2',
link: 'xx/xx'
}, {
title: 'title3',
link: 'xx/xx'
}];
}]);
myModule.directive('accordion', function($compile) {
return {
restrict: 'EA',
replace:true,
scope:{
expander:'=',
child:'='
},
template: "<ul > <li>{{expander.title}}</li></ul>",
link: function(scope,elm) {
if(scope.child){
var html=$compile("<accordion expander='expander' child='expander.child' ng-repeat='expander in child'></accordion>")(scope);
elm.append(html)
}
}
};
});
1.html
<body ng-app="myApp">
<section ng-controller="TestController">
<accordion expander='expander' child='expander.child' ng-repeat='expander in expanders'>
</accordion>
</section>
</body>
