在我的控制器中，我有如下数据: 美元的范围。对象=数据
现在这个数据是json中包含键和值的字典。
我可以在模板中使用object.name访问属性。是否有任何方法，我可以遍历键以及显示他们在表一样
<tr><td> {\ fnhobo std \ fs48} </td>数据。key) < / td >
数据是这样的
{
"id": 2,
"project": "wewe2012",
"date": "2013-02-26",
"description": "ewew",
"eet_no": "ewew",
}

如何:
<table>
<tr ng-repeat="(key, value) in data">
<td> {{key}} </td> <td> {{ value }} </td>
</tr>
</table>
该方法在文档中列出:https://docs.angularjs.org/api/ng/directive/ngRepeat

你可以在你的javascript(控制器)或在你的html(角视图)…
js:
$scope.arr = [];
for ( p in data ) {
$scope.arr.push(p);
}
html:
<tr ng-repeat="(k, v) in data">
<td>{{k}}<input type="text" ng-model="data[k]"></td>
</tr>
我相信html的方式更有棱角，但你也可以在你的控制器和检索它在你的html…
查看对象键也不是一个坏主意，如果你需要它们，它们会给你一个键数组，更多信息在这里:

</tr>
</table>
</td>
</tr>
</table>
</body>
<script type="text/javascript">
var app = angular.module("dashboard",[]);
app.controller("myController",function($scope){
$scope.collValues = {
'name':'string',
'id':'string',
'phone':'number',
'depart':[
{
'depart':'string',
'name':'string'
}
]
};
$scope.hasChildren = function(bigL1) {
return angular.isArray(bigL1);
}
});
</script>
</html>
我不认为angular中有一个内置函数可以做到这一点，但你可以通过创建一个包含所有头文件名称的单独scope属性来做到这一点，你可以像这样自动填充这个属性:
var data = {
foo: 'a',
bar: 'b'
};
$scope.objectHeaders = [];
for ( property in data ) {
$scope.objectHeaders.push(property);
}
// Output: [ 'foo', 'bar' ]
一个通过ng-repeat循环object的todo列表示例:
var app = angular.module('toDolistApp', []); app.controller('toDoListCntrl', function() { var self = this; self.toDoListItems = {};// []; //dont use square brackets if keys are string rather than numbers. self.doListCounter = 0; self.addToDoList = function() { var newToDoItem = {}; newToDoItem.title = self.toDoEntry; newToDoItem.completed = false; var keyIs = "key_" + self.doListCounter++; self.toDoListItems[keyIs] = newToDoItem; self.toDoEntry = ""; //after adding the item make the input box blank. }; }); app.filter('propsCounter', function() { return function(input) { return Object.keys(input).length; } }); <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <body ng-app="toDolistApp"> <div ng-controller="toDoListCntrl as toDoListCntrlAs"> Total Items: {{toDoListCntrlAs.toDoListItems | propsCounter}}<br /> Enter todo Item: <input type="text" ng-model="toDoListCntrlAs.toDoEntry"/> <span>{{toDoListCntrlAs.toDoEntry}}</span> <button ng-click="toDoListCntrlAs.addToDoList()">Add Item</button> <br/> <div ng-repeat="(key, prop) in toDoListCntrlAs.toDoListItems"> <span>{{$index+1}} : {{key}} : Title = {{ prop.title}} : Status = {{ prop.completed}} </span> </div> </div> </body>
Use below code it is working to display your key and value here is key start with 1:
<tr ng-repeat="(key,value) in alert_list" >
<td>{{key +1}}</td>
<td>{{value.title}}</td>
</tr>
Below is document link for it.
