我update img clicking时如何button图库var btn = document.getElementById('btn'),
link = document.querySelectorAll('.uk-subnav.uk-subnav-pill li');
btn.addEventListener('click', function() {
console.log('k');
link.forEach(function(elem) {
elem.classList.remove('uk-active');
});
document.getElementById('all').classList.add('uk-active');
});
？
目前我刚刚更新了活动课程，但没有设法恢复所有项目。
JS ：
<button type="button" id="btn" class="uk-button uk-button-secondary uk-position-center" style="top:1.5em;letter-spacing:.5em;">Back to top</button>
<div uk-filter="target: .js-filter">
<ul class="uk-subnav uk-subnav-pill">
<li id="all" class="uk-active" uk-filter-control><a href="#">All</a></li>
<li uk-filter-control="[data-color='white']"><a href="#">White</a></li>
<li uk-filter-control="[data-color='blue']"><a href="#">Blue</a></li>
<li uk-filter-control="[data-color='black']"><a href="#">Black</a></li>
</ul>
<ul class="js-filter uk-child-width-1-2 uk-child-width-1-3@m uk-text-center" uk-grid>
<li data-color="white">
<div class="uk-card uk-card-default uk-card-body">Item</div>
</li>
<li data-color="blue">
<div class="uk-card uk-card-primary uk-card-body">Item</div>
</li>
<li data-color="black">
<div class="uk-card uk-card-default uk-card-body">Item</div>
</li>
</ul>
</div>
HTML 的一部分：
output.set_shape(tensor_shape.TensorShape([None]).concatenate(shape))
