Я работаю над проектом под названием «Система управления золотыми кредитами». Form fields to insert the ornament name and weight.Total number of ornaments and total weight is calculated automatically .I Не удалось рассчитать общий вес dynamically.Here мой код ---динамически вычислять сумму значений в массиве с помощью Angular js
index.html
<fieldset data-ng-repeat="choice in choices">
<div class="form-group">
<select class="form-control" name="optioin" ng-model="choice.option" >
<option value="Ring">Ring</option>
<option value="Earings">Earings</option>
<option value="Chains">Chains</option>
<option value="Necklaces">Necklaces</option>
<option value="Bangles">Bangles</option>
</select>
</div>
<div class="form-group">
<input class="form-control" type="number" ng-model="choice.weight" name="" placeholder="Enter the weight">gm
<button class="btn btn-default" ng-show="$last" ng-click="removeChoice() "><span class="glyphicon glyphicon-minus" aria-hidden="true"></span></button>
<button class="btn btn-default" ng-show="$last" ng-click="addNewChoice()"> <span class="glyphicon glyphicon-plus" aria-hidden="true"></span></button>
</div>
</fieldset>
</form>
<form class="form-inline">
<div class="form-group">
<label for="totnumber">Total Nos:</label>
<input type="number" ng-model="choices.length" class="form-control" id="totnumber">
</div>
<div class="form-group">
<label for="totweight">Total Weight:</label>
<input type="number" ng-model="total" class="form-control" id="totweight">
</div>
</form>
dashboardcntrl.js
app.controller('dashboardCtrl', function($scope) {
$scope.choices = [{id: 'choice1'}];
$scope.addNewChoice = function() {
var newItemNo = $scope.choices.length+1;
$scope.choices.push({'id':'choice'+newItemNo});
console.log( $scope. choices.length);
};
$scope.removeChoice = function() {
var lastItem = $scope.choices.length-1;
$scope.choices.splice(lastItem);
console.log( $scope. choices.length);
};
});
