var inputs={
'firstname': '',
'lastName':'',
'account':{
'role':'',
'status':''
}
}
This is my model array. I want to display it dynamically in Webpage and by modifying the json array the changes should affect the form too.
Here is the image
UPD:
for your situation, you can use ng-switch to generate elements according to conditions.
Notice(already included in the code snippet):
ng-repeat will generate it's own scope, so your model won't update unless you bind it with the original scope. ref here.
OLD ANSWER:
use ng-model to implement two-way-databinding.
refer the code snippet below:
angular.module("app", []).controller("myCtrl", function($scope) {
$scope.inputs = {
'firstname': 'test first name',
'lastName': 'test last name',
'account': {
'role': 'test role',
'status': 'test status'
}
};
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.4/angular.min.js"></script>
<div ng-app="app" ng-controller="myCtrl">
<!-- First Name: <input type="text" ng-model="inputs.firstname"><br>
Last Name: <input type="text" ng-model="inputs.lastName"><br> Account Role: <input type="text" ng-model="inputs.account.role"><br>
Account Status: <input type="text" ng-model="inputs.account.status"><br> -->
<div ng-repeat="(key1, value) in inputs" ng-switch="key1">
<div ng-switch-when="account">
<div ng-repeat="(key2, value2) in value">
{{key1 | uppercase}} => {{ key2 | uppercase}}
<input type="text" ng-model="inputs[key1][key2]">
</div>
</div>
<div ng-switch-default>
{{key1 | uppercase}}
<input type="text" ng-model="inputs[key1]">
</div>
</div>
{{inputs}}
</div>/My html should look like this/
<head>
<script data-require="angular.js@1.4.1" data-semver="1.4.1" src="https://code.angularjs.org/1.4.1/angular.js"></script>
<script src="script.js"></script>
</head>
<body ng-controller="MainCtrl">
<script type="text/ng-template" id="tree-structure">
<label>{{dt}}</label><input type="text" name="" value="{{dt.label}}">
<ul class="childElement">
<li ng-repeat="dt in dt.nodes" ng-include="'tree-structure'">
</li>
</ul>
</script>
<ul class="parentList">
<li ng-repeat="(key, value) in inputs" >
<div ng-repeat="(key1, value1) in value">
<label>{{key1}}</label>
<input type="text" name="" value="{{value1}}">
<!-- <div ng-repeat="(key2, value2) in value1">
<label>{{key2}}</label><input type="text" name="" value="{{value2}}">
</div> -->
</div>
<div ></div>
</li>

Some observations :
JSON should be formatted properly with type of the field.If you want to access the object properties as a form fields then it should be structured in a good way so that we can dynamically add the type of the field as well.
[{
name: 'firstName',
type: 'text'
}, {
name: 'lastname',
type: 'text'
}, {
account: [{
name: 'role',
type: 'text'
}, {
name: 'status',
type: 'text'
}]
}]
As your JSON have nested objects. So, first iterate it recursively and create one dimensional array then create the fields using 1D array.
DEMO
var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl', function($scope) {
var inputs = [{
name: 'firstName',
type: 'text'
}, {
name: 'lastname',
type: 'text'
}, {
account: [{
name: 'role',
type: 'text'
}, {
name: 'status',
type: 'text'
}]
}];
$scope.fields = [];
function structuredObj(obj) {
for (var i in obj) {
if (obj[i].type == 'text') {
$scope.fields.push(obj[i]);
} else {
structuredObj(obj[i])
}
}
};
structuredObj(inputs);
