我有一个表单,当用户点击添加销售按钮时会增加
这是html
<fieldset data-ng-repeat="choice in choices">
<div class="form-group">
<label for="name">
Quantity :
</label>
<input type="text" class="form-control" id="choice.quantity" ng-model="choice.amount" />
</div>
如何在控制器中获取输入值
appcat.controller("MainCtrl", ['$scope', '$location', function ($scope, $location)
{
// this controll the addition and removal
$scope.choices = [{ 'amount': '' }];
// I want to set the input field
$scope.choice.amount = parseFloat(200* 4); // $scope.choice.amount and $scope.amount are not working
// this generate a form
$scope.addNewChoice = function()
{
var newItemNo = $scope.choices.length + 1;
$scope.choices.push({'amount': ''});
};
// this remove the form
$scope.removeChoice = function () {
var lastItem = $scope.choices.length - 1;
if ($scope.choices.length > 1) {
$scope.choices.splice(lastItem);
}
};
}
如何在控制器
中将输入值设置为此计算parseFloat(200* 4);

为此,您需要使用ng-model:
来自AngularDocs:
ngModel指令使用NgModelController将输入,select,textarea(或自定义表单控件)绑定到作用域上的属性,NgModelController由此指令创建并公开。

它可能只是您复制到stackoverflow的代码中的拼写错误,但您应该设置的变量是:
$scope.choices[0].amount = parseFloat(200* 4)
甚至更短:
$scope.choices = [{ 'amount': parseFloat(200* 4}];
