[英]Generate dynamic form input fields and collect field data in an array in angularJS
我需要通過單擊表單上的“添加銷售”按鈕來動態生成表單輸入字段。 完成了
同樣,在選定的更改下拉菜單中,它從數據庫中獲取價格,並使用數量來計算該產品的數量。
如果我點擊“添加銷售”按鈕以生成另一種形式,則更改會影響前一種形式。
如何獨立計算每種形式的金額並使用angularJS收集其中的數據?
這是控制器
appcat.controller("MainCtrl", ['$scope', '$http', '$location', function ($scope, $http, $location)
{
//var quan = $scope.quantity;
$http.get('/api/pproduct').success(function (data)
{
$scope.pcategoryA = data;
});
// this controll the addition and removal
$scope.choices = [{ id: 'choice1' }];
//any time changes occurr it calculate the Amount
$scope.changedValue = function (item,quan)
{
if (item != null && quan !=null)
{
$http.get('/api/product/'+ item).success(function (data) // this is the price for that product from the Database
{
//this sets amount field
$scope.amount = parseFloat(data.price * quan);
});
}
}
// this generate a form
$scope.addNewChoice = function ()
{
var newItemNo = $scope.choices.length + 1;
$scope.choices.push({ 'id': 'choice' + newItemNo });
};
// this remove the form
$scope.removeChoice = function () {
var lastItem = $scope.choices.length - 1;
if ($scope.choices.length > 1) {
$scope.choices.splice(lastItem);
}
};
}]);
這是HTML
<form class="form-inline" role="form" padding-left:10em">
<strong class="error">{{ error }}</strong>
<div class="form-group">
<label for="name">
Invoice No. :
</label>
<input type="text" class="form-control" id="name" ng-model="name" />
</div>
<br /><hr />
<div ng-controller="MainCtrl">
<fieldset data-ng-repeat="choice in choices">
<div class="form-group">
<label for="name">
Quantity :
</label>
<input type="text" class="form-control" id="quantity" ng-model="quantity" />
</div>
<div class="form-group">
<div class="form-group">
<label class="control-label"> Product : </label>
<select class="form-control" id="selected_id" ng-model="selected_id" ng-options="c.Value as c.Text for c in pcategoryA"
ng-change="changedValue(selected_id,quantity)">
<option value="">-- Select Category --</option>
</select>
</div>
</div>
<div class="form-group">
<label for="name">
Amount :
</label>
<input type="text" class="form-control" id="amount" ng-model="amount" ng-readonly="true" />
</div>
<button class="remove" ng-show="$last" ng-click="removeChoice()">-</button>
<br />
<hr />
</fieldset>
<button type="submit" class="col-sm-offset-10 addfields" ng-click="addNewChoice()">
Add Sale
</button>
</div>
</form>
提前致謝!!
您必須在選擇數組中放入“金額”。
$scope.choices = [{ id: 'choice1', amount: 0}];
然后在控制器中:
$scope.changedValue = function (choise,item,quan)
choise.amount = parseFloat(data.price * quan);
並且在臨時上:
ng-change="changedValue(choise,selected_id,quantity)">
<input type="text" class="form-control" id="amount" ng-model="choise.amount" ng-readonly="true" />
