我不知道js，但偶爾也要使用它，所以如果問題不重要，那麼很抱歉，但是我會嘗試不同的東西，但它們不適合我。tree-toggle在加載時關閉
所以我有一棵樹，我有這個腳本，實際上工作和隱藏顯示單擊樹枝時。
但是，默認情況下該樹已打開。如何強制樹在第一次加載時關閉？
<!--
- HIDE DISPLAY TREE BRANCH WHEN CLICKED ON HEAD ITEM -->
<script>
$(document).ready(fu
nction() {
$('label.tree-toggler').click(function() {
$(this).parent().children('ul.tree').toggle(300);
});
});
</script>
這是我的HTML源
