我正在尝试遍历等于props_nfl_days
的数组["Sunday", "Thursday Night", "Monday Night"]
,因此它在星期几显示为每组NFL得分的标题。该组件如下所示:
更新代码:
const nfl = {
nflComponent: Vue.component("tab-nfl", {
props: [
"props_league_data_nfl",
"props_nfl_days",
"props_league_standings"
],
template: `
<div class="vue-root-element">
<div class="container nfl-scores">
<div v-for="(dayDataArray, index) in props_league_data_nfl">
<p> {{ index }} </p>
<h2> {{ props_nfl_days[index] }} </h2>
<div class="row">
<div class="col-xs-12 col-md-4 col-lg-3" v-for="arrayItem in dayDataArray">
<table class="table table-striped table-sm">
<thead>
<th scope="col" class="box-score-status is-completed" v-if="arrayItem.isCompleted">Final</th>
</thead>
<tbody>
<tr>
<td class="box-score-team"> {{ arrayItem.game.awayTeam.Abbreviation }} </td>
<td class="box-score-inning" v-for="quarter_score in arrayItem.quarterSummary.quarter">
{{quarter_score.awayScore }}</span>
<td class="box-score-final" v-bind:class="{ won: arrayItem.awayScore > arrayItem.homeScore }">{{ arrayItem.awayScore }}
</td>
</tr>
<tr>
<td class="box-score-team"> {{ arrayItem.game.homeTeam.Abbreviation }} </td>
<td class="box-score-inning" v-for="quarter_score in arrayItem.quarterSummary.quarter">
{{quarter_score.homeScore }}
</td>
<td class="box-score-final" v-bind:class="{ won: arrayItem.homeScore > arrayItem.awayScore }">{{ arrayItem.homeScore
}}
</td>
</tr>
<tr><td class="box-score-team w-150">Location: {{ arrayItem.game.location }} </td></tr>
</tbody>
</table>
</div> <!-- End v-for dayDataArray -->
</div> <!-- End row -->
</div> <!-- End v-for props_league_data_nfl -->
</div> <!-- End container -->
我所得到的只是索引变为0,就这样。 props_league_data_nfl是具有三个属性的对象。这是Vue面板输出的快照:
我想要的是每个props_league_data_nfl组的h2标头中的正确nfl_days数组元素。查看图片:
我希望这些星期日标题分别是星期四晚上和星期一晚上。任何有关如何实现这一目标的指导都值得赞赏。
答案 0 :(得分:2)
计算的属性不应有副作用。根据计算属性的依赖关系对其进行缓存;由于increment
的依存关系没有任何变化,因此不会重新计算其值。因此,increment
将运行一次,并且始终返回相同的值:0
。
v-for
为密钥(在遍历objet属性的情况下)和当前索引采用其他参数,因此您可以删除increment
计算的属性并按如下方式重新编写模板:
<div v-for="(dayDataArray, key, index) in props_league_data_nfl">
**<h2> {{ props_nfl_days[index] }} </h2>**
