Question

I am creating invoice generator. In that I want to store the total,discount and all things in my database.
Total and discount are calculated as follow...
<tr ng-repeat="list in data">
<td>
<label class="clabel">Subtotal</label>
</td>
<td ng-model="subtotal">{{list.sale_price*list.quantity}}</td>
</tr>
<tr ng-repeat="list in data">
<td>
<label class="clabel">Tax(2%)</label>
</td>
<td ng-model="tax">{{((list.sale_price*list.quantity)*2)/100}}</td>
</tr>
<tr ng-repeat="list in data">
<td>
<label class="clabel">Discount(%)</label>
</td>
<td ng-model="discount">{{((list.sale_price*list.quantity)*list.discount)/100}}</td>
</tr>
<tr ng-repeat="list in data">
<td>
<label class="clabel">Total</label>
</td>
<td ng-model="total">{{((list.sale_price*list.quantity)+(((list.sale_price*list.quantity)*2)/100))-(((list.sale_price*list.quantity)*list.discount)/100)}}</td>

<td colspan="2">
<button class="btn btn-success" style="margin-left:400px;" ng-click="GenerateBill();updateAll()">Generate Invoice</button>

Answer 1

you can try this....
$scope.updateAll=function()
{
data={
subtotal:$scope.product.sale_prize*$scope.product.quantity,
tax:$scope.product.sale_prize * $scope.product.quantity*2/100,
discount:$scope.product.sale_prize * $scope.product.quantity*$scope.product.discount/100,
total:$scope.product.sale_prize * $scope.product.quantity+$scope.product.sale_prize * $scope.product.quantity*2/100-$scope.product.sale_prize *$scope.product.quantity* $scope.product.discount/100
}
$http.post("../pos_system/Widgets/updatedata.php?barc="+$scope.barc,data).success(function(data)
{
//do your stuff here;
});
}
Make this change in your HTML part
<tr >
<td>
<label class="clabel">Subtotal</label>
</td>
<td><input type="text" class="cinput" placeholder="sale price" ng-value="list.sale_price*list.quantity" readonly="" />
</td>
</tr>
<tr >
<td>
<label class="clabel">Tax(2%)</label>
</td>
<td><input type="text" class="cinput" placeholder="sale price" ng-value="((list.sale_price*list.quantity)*2)/100" readonly="" />
</td>
</tr>
<tr>
<td>
<label class="clabel">Discount(%)</label>
</td>
<td>
<input type="text" class="cinput" placeholder="sale price" ng-value="((list.sale_price*list.quantity)*list.discount)/100" readonly="" />
</td>
</tr>
<tr >
<td>
<label class="clabel">Total</label>
</td>
<td >
<input type="text" class="cinput" placeholder="sale price" ng-value="((list.sale_price*list.quantity)+(((list.sale_price*list.quantity)*2)/100))-(((list.sale_price*list.quantity)*list.discount)/100)" readonly="" />
</td>
</tr>
<tr>
<td colspan="2">
<button class="btn btn-success" style="margin-left:400px;" ng-click="GenerateBill();updateAll()">Generate Invoice</button>
</td>
</tr>
