arrays - 遍历数组 - 只打印一次？

Question

致力于循环遍历一组数据并将食物名称添加到一个数组中。当前设置如下:

注意:allDBfoods 是数据库中食物数据的集合。

<% var breakfastFoods = []  %>
<% for (var food of allDBFoods) { %>
    <% if (food.breakfast == true ){ %>

        <% breakfastFoods.push(food.name) %>
        <% console.log(breakfastFoods)%>
    <% } %>
<% } %>

这有效但返回

[ 'Eggs' ]
[ 'Eggs', 'Bacon' ]
[ 'Eggs', 'Bacon', 'poptarts' ]

我只想让它做一个数组。有什么建议吗？

尝试在for 循环之外使用log:

<% var breakfastFoods = []  %>
<% for (var food of allDBFoods) { %>
    <% if (food.breakfast == true ){ %>    
        <% breakfastFoods.push(food.name) %>
    <% } %>
<% } %>
<% console.log(breakfastFoods)%>
