我有一个特定的要求,const_cast<>()
数据是这样的:
json
我希望使用[{Id : "a", Name : "John", age : 50},
{Id : "b", Name : "Bob", age : 40}]
在表格中显示它,但是在第一列中标题出现的方式如下所示:
ng-repeat
有没有办法使用<table>
<tr>
<td>Id</td>
<td>a</td>
<td>b</td>
</tr>
<tr>
<td>Name</td>
<td>John</td>
<td>Bob</td>
</tr>
<tr>
<td>Age</td>
<td>50</td>
<td>40</td>
</tr>
</table>
来实现这一目标?

如果您有控制器:
#include <mechsys/adlbm/Domain.h>
您的标记将如下所示。如果数据在显示后不会改变:
angular.module('MyApp', [])
.controller('MyController', function($scope) {
$scope.data = [
{Id : "a", Name : "John", age : 50},
{Id : "b", Name : "Bob", age : 40}
];
});
如果数据在显示后会发生变化,并且您希望视图相应更新,那么:
<table>
<tr>
<td>Id</td>
<td ng-repeat="item in ::data">{{::item.Id}}</td>
</tr>
<tr>
<td>Name</td>
<td ng-repeat="item in ::data">{{::item.Name}}</td>
</tr>
<tr>
<td>Age</td>
<td ng-repeat="item in ::data">{{::item.age}}</td>
</tr>
</table>

您可以在对象中转换数组,然后可以在视图中使用嵌套的ng-repeats,如下所示:
(function() {
"use strict";
angular.module('app', [])
.controller('mainCtrl', function($scope) {
var array = [
{
"Id":"a",
"Name":"John",
"age":50
},
{
"Id":"b",
"Name":"Bob",
"age":40
}
];
// If you're sure that the properties are always these:
$scope.mainObj = {
"Id": [],
"Name": [],
"age": []
};
// If you're unsure what are the properties:
/*
$scope.mainObj = {};
Object.keys(array[0]).forEach(function(value) {
$scope.mainObj[value] = [];
});
*/
// Iterates over its properties and fills the arrays
Object.keys($scope.mainObj).forEach(function(key) {
array.map(function(value) {
$scope.mainObj[key].push(value[key]);
})
});
});
})();

我希望它有所帮助!
