我有以下的JSON對象：Angularjs嵌套MD-虛擬重複
[
{
"districtId": 1,
"districtAddress": "108 N MAIN ST",
"offices": [
{
"Id": 11,
"name": "test",
"City": "ATMORE"
},
{
"Id": 22,
"name": "test",
"City": "ATMORE"
}
]
},
{
"districtId": 2,
"districtAddress": "108 N MAIN ST",
"offices": [
{
"Id": 33,
"name": "test",
"City": "ATMORE"
},
{
"Id": 44,
"name": "test",
"City": "ATMORE"
}
]
},
{
"districtId": 3,
"districtAddress": "108 N MAIN ST",
"offices": [
{
"Id": 55,
"name": "test",
"City": "ATMORE"
}
]
}
]
我想用md-virtual-repeat指令來顯示此數據。當我使用這個指令時，一級中繼器工作。 但是，當我嘗試使用相同的指令呈現內部數據 - 它不會按預期工作。如何使用md-virtual-repeat爲嵌套中繼器（我想擺脫ng-repeatmd-list-item元素）？
這裏是我的代碼：
angular
.module('MyApp',['ngMaterial'])
.controller('AppCtrl', function($scope) {
var self = this;
self.items = [];
for (var i = 0; i < 1000; i++) {
var item = {
nbr: i,
items: []
};
for(var m = 0; m < 10; m++) {
item.items.push({
nbr: m,
checked: true
});
}
self.items.push(item);
}
});.virtualRepeatStoreList .vertical-container {
height: 500px;
width: 100%;
}
.virtualRepeatStoreList .repeated-item {
border-bottom: 1px solid #ddd;
box-sizing: border-box;;
height: 40px;
padding-top: 10px;
}
.virtualRepeatStoreList md-content {
margin: 16px;
}
.virtualRepeatStoreList .md-virtual-repeat-container .md-virtual-repeat-offsetter div {
padding-left: 5px;

這是一個完成此操作的codepen：https://codepen.io/semihgk/pen/Pzrwkj。除了你的數據結構之外，你不會得到任何幫助。 –
不，我也想在內部數據中使用虛擬中繼器。 – Aswathy
@ShriyaR你是否嘗試過從我的答案中使用標記？ –
