classTest{staticvoidmain(args){// 为 ArrayList 设置初始值def list=["1","2","3"]// I. 闭包中使用 == 作为查找匹配条件def findElementResult=list.find{// 查找集合中值为 "1" 的元素// 此处的 == 等价于 Java 中调用 String 的 equals 方法 , 不是比较地址i
jQuery .find()方法用于在匹配的元素集合中查找符合指定条件的后代元素。它接受一个选择器作为参数,并返回一个新的 jQuery 对象,包含所有匹配的后代元素。 相关优势 简洁性:使用 jQuery 可以简化 DOM 操作,使代码更加简洁易读。 兼容性:jQuery 处理了不同浏览器之间的兼容性问题,开发者无需担心跨浏览器差异。
