jquery实现找到<div data-id="123"></div>这个div的代码
以下是使用 jQuery 找到 `<div data-id="123"></div>` 这个元素的代码： ```javascript // 使用属性选择器来查找具有 data-id 属性且值为 123 的 div 元素 var targetDiv = $('div[data-id="123"]'); // 可以通过以下方式验证是否找到了元素 if (targetDiv.length > 0) { console.log('找到了指定的 div 元素'); } else { console.log('未找到指定的 div 元素'); } ``` 我在以往的开发过程中，碰到过以下几点需要格外小心处理的地方： 1. 确保在使用 jQuery 代码之前，已经正确引入了 jQuery 库，否则代码将无法正常运行。 2. 要注意属性值的大小写，因为在 HTML 属性选择时是区分大小写的。 3. 如果页面上动态添加或移除元素，可能需要在元素添加后再执行查找操作，否则可能找不到元素。 [2026-01-06 21:19:13 | AI写代码神器 | 217点数解答]
