AngularJS. Converting form fields to json
提问by ses
Trying to understand how could be possible to write a function, (directive / controller) that would transform all my form inputsto json with current value that they have to json.
试图了解如何编写一个函数（指令/控制器），将我的所有内容转换form inputs为具有当前值的 json json。
The json would have a format similar to that:
json 的格式类似于：
{
fields: [
{field1: value1},
{field2: value2},
{field3, value3}
]
}
Where to start from at least.. with no jqueryapplying?
至少从哪里开始......没有jquery申请？

ng-modeldoes it for you. A scope variable will be created if you haven't already created it yourself
ng-model为你做。如果您尚未自己创建范围变量，则会创建它
<form name="myForm" ng-submit="submitMyForm()">
<input ng-model="fields.name" />
function myController($scope){
$scope.submitMyForm=function(){
/* while compiling form , angular created this object*/
var data=$scope.fields;
/* post to server*/
$http.post(url, data);
}
}
If you have the object to start with in your scope angular will 2 way bind to the input, so any values that are initially set in the scope object will show up in the input
如果您的范围内有对象开始，angular 将以两种方式绑定到输入，因此最初在范围对象中设置的任何值都将显示在输入中
