目前有这么个需求：
订单结算页面有多个订单。
我想通过订单各自的价格*数量，然后相加得出总共需要支付的金额，怎么计算？
//最后显示提示用户：总额：xxx元,去支付。
使用vuejs的computed属性进行计算吗？
那怎么循环多个订单进行乘法加法？
数据：
{
"status": 1,
"info": "订单信息",
"data": [
{
"dcprice": null,
"kitchen_status": "0",
"discount_items": "1",
"discount_id": "",
"status": "0",
"choice_dish_ingredients": "",
"choice_taste": "",
"price": "55.00",
"quantity": "1.00",
"give_quantity": "0.00",
"cancel_quantity": "0.00",
"dish_name": "菜品3",
"pic": "",
"dish_price": "55.00",
"discount": "0.00",
"introduce": " ",
"type": "1",
"taste_name": null,
"classify_name": "jjj",
"type_name": "菜类型1"
},
{
"dcprice": null,
"kitchen_status": "0",
"discount_items": "1",
"discount_id": "",
"status": "0",
"choice_dish_ingredients": "",
"choice_taste": "",
"price": "4.00",
"quantity": "2.00",
"give_quantity": "0.00",
"cancel_quantity": "0.00",
"dish_name": "菜品1",
"pic": "",
"dish_price": "4.00",
"discount": "0.00",
"introduce": " ",
"type": "1",
"taste_name": null,
"classify_name": null,
"type_name": "菜类型2"
}
]
}然后我的vue实例：
//dishorder 就是存着上面数据的变量
new Vue({
el:'#js_show_footer',
data:dishorder,
computed:{
//计算总价,用于显示
_price:function () {
var allPrice=0;
var i=0;
//下面怎么写？
/*for(){
}*/
return allPrice;
}
}
});对于简单操作后仅做显示，可以用filter来实现
注意这几个属性：
循环this.$data.data 或者 this.data计算
