我正在尝试用ng-model建立一个数组，
<div ng-repeat="n in [1, 2, 3]">
<input type="text" class="form-control" ng-model="headers[$index].key">
<input type="text" class="form-control" ng-model="headers[$index].value">
</div>
当我做
angular.toJson ($scope.headers)时，我得到：{
"headers": {
"0": {
"key": "xxx",
"value": "yyy"
}
}
}
但是我想要这个
{
"headers": [
{
"key": "xxx",
"value": "yyy"
}
]
}
不可能做到这一点吗？
最佳答案
你是这个意思吗？

index.js
<!DOCTYPE html>
<html ng-app="plunker">
<head>
<meta charset="utf-8" />
<title>AngularJS Plunker</title>
<script>document.write('<base href="' + document.location + '" />');</script>
<link rel="stylesheet" href="style.css" />
<script data-require="angular.js@1.4.x" src="https://code.angularjs.org/1.4.2/angular.js" data-semver="1.4.2"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<div ng-repeat="object in transformedData">
<input type="text" class="form-control" ng-model="object.key">
<input type="text" class="form-control" ng-model="object.value">
</div>
<pre>{{transformedData}}</pre>
</body>
</html>
app.js
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
var data = {
"headers": {
"0": {
"key": "xxx",
"value": "yyy"
}
}
};
$scope.transformedData = transformData(data.headers)
function transformData(data){
var arr = [];
for(var key in data){
arr.push(data[key])
}
return arr;
}
});
