我的代码是这样的:
<div class="row no-gutter">
<div class="col-md-3">
<h2 class="nav-cat-text">By Types</h2>
</div>
<div class="col-md-9 col-xs-12">
<div class="wrap-tabs">
<ul class="nav nav-tabs nav-cat">
@foreach($categories as $category)
<li role="presentation" class="{{ $loop->first ? 'active' : '' }}"><a href="javascript:;" data-toggle="tab" @click="$refs.player.getPlayer({{ $category->id }})">{{ ucfirst($category->name) }}</a></li>
@endforeach
</ul>
</div>
</div>
</div>
<br>
<!-- Tab panes -->
<div class="tab-content">
<div role="tabpanel" class="tab-pane active">
<top-player-view category_id="1" ref="player"></top-player-view>
</div>
</div>
top-player-view中的category_id属性是静态的
我想让它变得更有活力。所以,我希望在$ categories
的第一个循环中从category_id获取category_id属性我该怎么做?
答案 0 :(得分:1)
试试这个: [我只输入了改变的部分,你可以理解。]
@foreach($categories as $category)
<li> ... </li>
@php
if ($loop->first)
$variable = $category->id
@endphp
@endforeach
...
<top-player-view category_id="{{ $variable }}" ref="player"></top-player-view>
