我需要通过单击按钮添加到“订单列表”元素,而不是通过输入表单的用户输入。 如何在控制器中使用从$ click函数派生的var?
CODE
var app = angular.module('myApp', []);
app.controller('POSController', function ($scope) {
var x=choose;
$scope.food = {
pizza : {count: 1, id:2, detail: "Brick Oven Pizza", price: 15},
donut : {count: 3, id:3, detail: "Glazed Donut",price: 8},
tortilla : {count: 1, id:4, detail: "Tortilla Chips",price: 3},
burger : {count: 1, id:5, detail: "Burger",price: 3},
samosa : {count: 1, id:6, detail: "Delicious Samosas",price: 3},
coldcoffee : {count: 1, id:7, detail: "Cold Coffee",price: 2},
hotcoffee : {count: 1, id:8, detail: "Hot Coffee",price: 2},
coke : {count: 1, id:9, detail: "Coke",price: 2},
dietcoke : {count: 1, id:10, detail: "Diet Coke",price: 2},
pepsi : {count: 1, id:11, detail: "Pepsi",price: 2},
incognita: {count: 1, id:12, detail: x, price: 2},
};
});
我需要为数组的最后一个元素的变量x分配临时值,以便每个输入都有新值。 我附上了我的PLUNK http://plnkr.co/edit/CoSAgGAco016pEIcRtLi?p=preview

我添加了一个带有ng-click事件的按钮,如下所示:
<button ng-click='addthisItem(nome)'>Add item</button>
然后在你的控制器中:
$scope.addthisItem = function(nome) {
if ($scope.food.hasOwnProperty(nome)) {
$scope.add($scope.food[nome]);
}
else {
//some error handling here
}
}
这是带有代码的plunker。
希望它有所帮助。
