<p>我需要在 if-else 子句中通过 URL 检查“perPage=100”和“perPage=50”。</p> <pre class="brush:php;toolbar:false;">@if(perPage=100) &lt;a class=&quot;btn btn-default btn-sm ajax-link back-btn&quot; href=&quot;invoice-list?perPage=100&quot; type=&quot;button&quot; &gt;Back to List&lt;/a&gt; @elseif(perPage=50) &lt;a class=&quot;btn btn-default btn-sm ajax-link back-btn&quot; href=&quot;invoice-list?perPage=50&quot; type=&quot;button&quot; &gt;Back to List&lt;/a&gt; @else &lt;a class=&quot;btn btn-default btn-sm ajax-link back-btn&quot; href=&quot;invoice-list?perPage=10&quot; type=&quot;button&quot; &gt;Back to List&lt;/a&gt; @endif</pre></p>

<a class="btn btn-default btn-sm ajax-link back-btn" href="{{url('invoice-list?perPage=' . $perPage)}}" type="button">Back to List</a>
