我在我的应用程序中使用MEAN堆栈，将AngularJS作为我的前端。如何在angularjs中总和两个值，实际上我们有两个表，第一个表用filter:{raised: 'false'}过滤，第二个表用filter:{raised: 'true'}过滤，我们得到{{1}中两个表的总和值那么我希望将commision总计值commision计算为A + B ... My Plunker。
我们有两个表，所以我想计算第一个表45 + 19 answer = 64总和值和第二个表commision总计值。
这两个表都使用ng-module值进行过滤，例如： - 第一个表格使用commision进行过滤，第二个表格使用filter:{raised: 'false'}进行过滤
期望例证： - fisrt表commision为filter:{raised: 'true'}，第二个表commision为45，我们需要计算这些值为第三个表，如19应该是A + B。
我已将羽毛作为参考plunker，任何人都知道解决方案可以帮助我们。
我的控制器： - Commision totalsum过滤器： -
64我的Html： -
.filter('totalSumCV', function () {
return function (data, key1, key2) {
if (angular.isUndefined(data) && angular.isUndefined(key1) && angular.isUndefined(key2))
return 0;
var sum = 0;
angular.forEach(data,function(v,k){
sum = sum + (parseFloat(v[key1]) * parseFloat(v[key2])/100);
});
return sum.toFixed(2);
}
})
我试图计算两个表的commision totalsum值，如： -
<tr ng-repeat="mani in resultValue=(sryarndebitnote | filter:{raised: 'false'} )">
<td>A = {{resultValue | totalSumCV:'invoice_value_fob':'percentage_commission'}}</td>
</tr>
<tr ng-repeat="mani in resultValue=(sryarndebitnote | filter:{raised: 'true'} )">
<td>B = {{resultValue | totalSumCV:'invoice_value_fob':'percentage_commission'}}</td>
</tr>
答案 0 :(得分：0)
您应该为结果集采用不同的变量来实现此目的，
这是您要求的答案，
var app = angular.module('plunker', []);
app.filter('sumOfValue', function () {
return function (data, key) {
debugger;
if (angular.isUndefined(data) && angular.isUndefined(key))
return 0;
var sum = 0;
angular.forEach(data,function(v,k){
sum = sum + parseFloat(v[key]);
});
return sum.toFixed(2);
}
}).filter('totalSumCV', function () {
return function (data, key1, key2) {
if (angular.isUndefined(data) && angular.isUndefined(key1) && angular.isUndefined(key2))
return 0;
var sum = 0;
angular.forEach(data,function(v,k){
sum = sum + (parseFloat(v[key1]) * parseFloat(v[key2])/100);
});
return sum.toFixed(2);
}
}).controller('MainCtrl', function($scope) {
$scope.sryarndebitnote = [
