我正在循环访问一些API数据,无法访问对象的一部分。
I am using v-for method in vue.js. In the main div I loop through using
the iterator recipe, it works for everything except for
analyzedInstructions.steps
<div class="food" v-for="(recipe,index) in recipes"
v-bind:recipe="recipe"
v-b
如何从数据库获取呈现数据的前两个字符?
<div v-for="(schedule,index) in DailySchedule" v-bind:key="index">
<span class="days-div">
<span class="day" v-for="(days,index) in schedule" v-bind:key="index.id">
<span v-for="(day,index) in d
这让我抓狂,我在一个数组中嵌套了数据,但没有成功地使用组件来呈现它,尽管我可以在没有组件的情况下呈现它。

<template lang="pug">
div(v-for="index in 4")
gs-input(
label="From",
v-bind:prop1="values.key + index + vals" // Does not work
v-bind:prop2="`values.key${index}vals`
<div id="app-7">
<ol>

Now we provide each todo-item with the todo object
it's representing, so that its content can be dynamic.
We also need to provide each component with a "key"
-->
<todo-item
