我有一个允许我显示一些数据的计算方法:
productsSpecification() {
var names = [];
var numbers = [];
this.cart.items.forEach(function(item) {
names += "Item: " + item.product.name + " -";
numbers += " Amount: " + item.quantity + ", ";
});
var together = names + numbers;
return together;
}
我想按顺序显示元素:来自' name'数组+元素来自'数字'数组:'Item: item1 - Amount: 1'
。

您可以像这样映射:
productsSpecification() {
return this.cart.items.map(function(item) {
return `Item: ${item.product.name} - Amount: ${item.quantity}`; // or "Item: " + item.product.name + " - Amount: " + item.quantity;
}).join(', ')
}
