回答1:写了一个sample做参考:
<body ng-app='orderSum'> <table ng-controller='orderController'><thead> <tr><th>序号</th><th>数量</th><th>单价</th><th>总价</th> </tr></thead><tbody ng-repeat='order in orders track by $index'> <tr><td>{{ $index+1 }}</td><td><input ng-model='order.count'></td><td><input ng-model='order.price'></td><td><input readonly='true' value='{{ order.count * order.price }}'></td> </tr></tbody> </table> <script> var myApp = angular.module('orderSum',[]); myApp.controller('orderController',[’$scope’,function($scope){$scope.orders=[];$scope.orders.length=10; }]); </script></body>回答2:
ng-repeat + array.push({id:1,name:’’,price:0,num:0})
ng-repeat=’x in array’
ng-model=’x.num’
ng-model=’x.price’
ng-bind=’x.num * x.price’
