我试图传递一个JSON响应,我返回一个空的数据对象以显示搜索结果并收到一个typeerror: arr.slice is not a function
错误。如果我将JSON直接添加到“学校”数据对象,则不会收到该错误。我认为这可能与JSON的格式有关?一切都包裹在一个名为“ hit”的数组中,我认为我的代码并不期望这样。
这是我的主要App.vue文件:
<template>
<div class="app search">
<!-- Search header -->
<header id="searchHeader" class="search--header py-2 py-md-4">
<div class="container">
<div class="input-group">
<!-- Search box -->
<SearchBox v-model="searchTerm"/>
<!-- Search button -->
<button v-on:click="searchSubmit(searchTerm)" class="btn btn-lg btn-white ml-2 px-4 search-submit">Search</button>
</div>
</div>
</header>
<!-- Main results -->
<div class="container">
{{ dataReceived }}
<!-- Result count and show/sort -->
<ResultCount v-model="page" :items="schools.length" :perPage="10"/>
<!-- Results -->
<SchoolList :schools="pageOfSchools"/>
</div>
</div>
</template>

这是要传递的JSON:
{

"start": "0",
"cursor": "",
"returned": 18,
"hit": [{

"schoolUrl": "http://localhost/school/10/State Peter Pan Institute",
"schoolLogo": 10
}, {

"city": "New Ulices",
"state": "Maryland",
"areasofstudy": "Bachelor's",
"degreetype": "BACHELORS",

}]
}
答案 0 :(得分:0)
似乎SchoolList
组件需要一个数组,因此您可以简单地更改行
this.schools = response.data
到
this.schools = response.data.hit
尽管如此,这取决于组件的构建方式。
