我在我的应用程序中使用 MEAN 堆栈,并将 AngularJS 作为我的前端。如何ng-bind
totalsum
值(value)转化为另一个input
在 Agularjs 中,实际上我们有一个表,我们使用过滤器来获取 Sprice
的总和值,那么我们也得到了sprice
总和值,如 250
,那么我们真正期待的是我们需要 bind
这个totalsum
值(value)转化为另一个ng-module
输入.... 例如:- sprice totalsum
值为 250
, 期待 ng-bind
的回答值为 totalsum value
喜欢250
... My Plunker .我们不知道我们在哪里犯了错误所以请调查 plunker 并帮助我们..
我们有一个表,在表中我们使用过滤器功能来获取
sprice
的总和值,我们使用这个<td>{{resultValue | sumOfValue:'sprice'}}</td>
得到了 250 个答案.我们期望我们需要什么
bind
sprice
totalsum 值到另一个ng-module
喜欢sprice_total
输入..期待答案250
...我已将 plunker 作为引用 plunker请任何知道解决方案的人帮助我们。
我的 Controller :- 价格总和过滤器:-
.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){
if(v.confirm=='cancelled'){
sum = sum + parseFloat(v[key]);
}
});
return sum.toFixed(2);
}
})
我的 Html:-
<tr ng-repeat="ram in resultValue=(order.orderfood) | filter: {confirm: '!cancelled'}">
<td>{{$index + 1}}</td>
<td>{{ram.sprice }}</td>
</tr>
<tr>
<td>sum</td>
<td>{{resultValue | sumOfValue:'sprice'}}</td>
</tr>
我尝试使用 ng-bind 将值获取到另一个输入,例如:-
<input type="text" ng-model="sprice_total" ng-bind="sprice_total={{resultValue | sumOfValue:'sprice'}}">
- 请同时更新 plunker 以了解解决方案...谢谢...
最佳答案
已创建 myModelValue 指令,它将您的表达式分配给 ng-model 对象
以下是引用 link
var app = angular.module('plunker', []);
app.directive('myModelValue', function () {
return {
restrict: 'A',
require: 'ngModel',
scope: {
model: '=ngModel'
},
link: function (scope, element, attr, controller) {
attr.$observe('myModelValue', function (finalValue) {
scope.model = finalValue;
});
}
};
});
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) {
if (v.confirm == 'cancelled') {
sum = sum + parseFloat(v[key]);
}
});
return sum.toFixed(2);
}
}).controller('MainCtrl', function ($scope) {
$scope.order =
