我按照本教程：https://tympanus.net/codrops/2013/06/26/expanding-search-bar-deconstructed/进行了扩展搜索栏。但是javascript似乎并没有起作用。
编辑问题的Codepen：https://codepen.io/marinel2v/pen/Ljoyvz
这是我的标记：
<div id="sb-search" class="sb-search">
<form role="search" method="get" action="<?php echo home_url( '/' ); ?>">
<input class="sb-search-input" placeholder="Rechercher un artiste, un événement, ..." type="search" value="" name="search" id="search" autocomplete="off">
<input class="sb-search-submit" type="submit" value="">
<span class="sb-icon-search"><?php get_template_part( 'svg/loupe' ); ?></span>
</form>
</div>
如您所见，我添加了console.log('starting');和console.log('click');
第一个是射击，但不是第二个。
我不明白为什么当我点击搜索按钮时没有任何反应......

'use strict';
console.log('starting');
