Question

我在ng-repeat内输入，输入有一个来自数据库的值。我需要将对象的输入发布到服务器但是未定义。但是，当您触摸或更改输入值时，它可以正常工作。为什么输入仅在您触摸或更改值时触发？

HTML

Parse error: syntax error, unexpected 'readphp' (T_STRING), expecting ',' or ';'

JS

<form name="form">
<ul>
    <li ng-repeat="val in vals track by $index">
        <input type="text" ng-value="val.ID" ng-model="data.val[$index]">
    </li>
</ul>
<button type="button" ng-click="Submit()">Submit</button></form>

Answer 1

<form name="form">
<ul>
    <li ng-repeat="val in vals track by $index">
        <input type="text" ng-init="data.val[$index] = val.ID" ng-model="data.val[$index]">
    </li>
</ul>
<button type="button" ng-click="Submit()">Submit</button></form>

Answer 2

var app = angular.module('app', []);
app.controller('Controller', function($scope){
$scope.data = {val:{}};

$scope.Submit = function(){
  var formdata = JSON.stringify($scope.data.val);

  $http.post("post.php", {"val":formdata})
    .then(function(response){
      console.log(response.data);
  });
}});
