我要求在两个表格中显示类别和子类别列表。要在HTML中显示类别数据:
<tr ng-repeat="item in addNodeCtrl.categoryData track by $index">
<td>{{item.name}}</td>
<td>
<input type="checkbox" ng-model="item.active">
此处将显示第一个表中的类别和类别活动/非活动开关。
在第二个表中,我只需要显示第一个表中通过交换机激活的类别。它将显示子类别及其活动/非活动状态。 HTML下面:
<table ng-repeat="item in ctrl.categoryData | filter:{active:true} track by $index" ng-init="ctrl.getsubCategory(item.id)">
<tbody>
<tr>
<td>{{item.name}}></td>
<td>
<table>
<tr ng-repeat="item1 in ctrl.subCategoryData track by $index">
<td>{{item1.name}}</td>
<td><input type="checkbox" ng-model="item1.active">
</td>
</tr>
</table>
</td>
</tr>
</tbody>
</table>
item.id是类别ID,JS中的getsubCategory函数在下面给出
JS下面:
function getsubCategory(categoryid) {
getsubcategservice.getsubcateg({categoryid: categoryid},{})
.$promise.then(success,failure);
function success(response){
vm.subCategoryData = response.data.subCategorys;
}
function failure(reason){
//error message
}
}
这里的问题是,当我使第一个类别切换处于活动状态时,将填充子类别,但是当第二个类别切换处于活动状态时,第一组子类别也会更改并列出第二个类别的子类别活性
请在下面找到类别的JSON数据:
{
"categoryInfoes": {
"categoryInfo": [
{
"active": "true",
"description": "category 1",
"id": "1",
},
{
"active": "true",
"description": "category 2",
"id": "2",
},
{
"active": "true",
"description": "category 3",
"id": "3",
}
]
}
}
请在下面找到子类别的JSON:
{
"subcategoryDetails": {
"subCategorys": [
{
"active": "true",
"name": "1 - subcategory 1",
},
{
"active": "true",
"name": "1 - subcategory 2",
},
{
"active": "true",
"name": "1 - subcategory 3",
},
{
"active": "true",
"name": "1 - subcategory 4",
}
],
"active": "true",
"description": "category 1",
"id": "1",
}
}
{
"subcategoryDetails": {
"subCategorys": [
{
"active": "true",
"name": "2 - subcategory 1",
},
{
"active": "true",
"name": "2 - subcategory 2",
},
{
"active": "true",
"name": "2 - subcategory 3",
},
],
"active": "true",
"description": "category 2",
"id": "2",
}
}
{
"subcategoryDetails": {
"subCategorys": [
{
"active": "true",
"name": "3 - subcategory 1",
},
{
"active": "true",
"name": "3 - subcategory 2",
},
{
"active": "true",
"name": "3 - subcategory 3",
},
],
"active": "true",
"description": "category 3",
"id": "3",
}
}
有人可以帮我解决这个问题吗?
更新
我创建了一个Plunker来演示这个: https://plnkr.co/edit/LqioF8hugsjJCOfmj9Vb?p=preview
如果您在Plunk中看到,如果您检查&#34;类别2&#34;在检查&#34;类别1和#34;之后,子类别针对类别1和类别2进行更新。类别3的相同幸福感。最后一个项目的子类别在任何地方都更新。 请帮帮我,让我知道我做错了什么,
答案 0 :(得分:0)
这里的问题是您要将子类别加载到范围中,然后在每次选择类别时更改范围中的值。就Angular而言,您只想重复并多次显示该信息。解决此问题的一种方法是将子类别嵌套到其父类别对象中,并将ng-repeat绑定到其父类的子子类别。
如果数据量过大,无法一次加载所有内容,您甚至可以在选中它们时动态加载这些内容。
如果这有意义,请告诉我。
- 编辑 - 由于我一天都没有收到你的消息,我决定添加一个plunkr来告诉你我在说什么:
https://plnkr.co/edit/mquYiX?p=preview
这是控制器:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,$http) {
// I made the subcategory data an array
$scope.subcategoryData = [];
$http.get("data.json")
.then(function(response) {
$scope.categoryData = response.data;
});
$scope.getsubCategory = function (categoryid) {
$http.get("data"+categoryid+".json")
.then(function(response) {
// the subcategories are keyed on the category Id
// and updated each time the method is called
$scope.subcategoryData[categoryid] = response.data;
console.log($scope.subcategoryData[categoryid]);
})
};
});
这是你的HTML:
<table ng-repeat="item in categoryData.categorydetail | filter:{active:true} track by $index" >
<tbody>
<tr>
<td>{{item.name}}></td>
<td ng-init="getsubCategory(item.id)">
<table>
<!-- here, I key the subcategoryData in the loop on the Item id. Voila, now it works -->
<tr ng-repeat="item1 in subcategoryData[item.id].subcategoryinfo track by $index">
<td>{{item1.subname}}</td>
<td><input type="checkbox" ng-model="item1.subactive"></td>
</tr>
</table>
</td>
</tr>
</tbody>
