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",
}

我们可以遵循以下过程来避免按字母顺序显示键值。
Javascript
$scope.data = {
"id": 2,
"project": "wewe2012",
"date": "2013-02-26",
"description": "ewew",
"eet_no": "ewew",
};
var array = [];
for(var key in $scope.data){
var test = {};
test[key]=$scope.data[key];
array.push(test);
}
$scope.data = array;
HTML
<p ng-repeat="obj in data">
<font ng-repeat="(key, value) in obj">
{{key}} : {{value}}
</font>
</p>

<body ng-controller="myController">
<table border='1'>
<tr ng-repeat="(key,val) in collValues">
<td ng-if="!hasChildren(val)">{{key}}</td>
<td ng-if="val === 'string'">
<input type="text" name="{{key}}"></input>

<td ng-if="val === 'number'">
<input type="number" name="{{key}}"></input>

<td ng-if="hasChildren(val)" td colspan='2'>
<table border='1' ng-repeat="arrVal in val">
<tr ng-repeat="(key,val) in arrVal">
<td>{{key}}</td>
<td ng-if="val === 'string'">
<input type="text" name="{{key}}"></input>
</td>
<td ng-if="val === 'number'">
<input type="number" name="{{key}}"></input>
</td>
</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);

如果你想用两种方式绑定编辑属性值:
<tr ng-repeat="(key, value) in data">
<td>{{key}}<input type="text" ng-model="data[key]"></td>
</tr>
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.
https://docs.angularjs.org/api/ng/directive/ngRepeat
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' ]
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:
