如何通過 JavaScript 或 JQuery 中的 div 標簽之間的標簽獲取元素？

Question

我在兩個 div 標簽中有一個名為path的標簽，當我點擊 div id toto而不是tata時，我想隱藏它。

我可以用 JavaScript 做到這一點嗎？

<div id="tata">

</div>

這是向我的元素添加 CSS 樣式的代碼：

$("path").css("display", "none");

但現在的問題是，我只想為 div id toto的path標記添加該樣式。

注意：名為Path的標簽沒有 ID，我無法添加它。

Answer 1

以下表達式將在 div toto的單擊處理程序期間定位path元素並將其隱藏。

$('#toto').on('click',function()
{
       $(this).find("path").hide();
});

Answer 2

您可以選擇包含所需路徑元素的 div，然后在其下方找到路徑標記。

$('#toto').find('path').css('display', 'none');

https://api.jquery.com/find/

您也可以直接引用元素：

$('#toto path').css('display', 'none');

但是 iirc 使用find()將導致在查找代碼中的元素時進行一些優化。
