之前写了一篇javascript防抖是应用在按钮中的

今天继续完善一下,下面的函数ruben就算循环10亿次，一秒内也会只调用一次

|---------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | hljs javascript var antiShakeFlag = false; function ruben() { if (antiShakeFlag) { return; } console.log("ruben") antiShakeFlag = true; setTimeout(() => { antiShakeFlag = false; }, 1000); } for (let i = 0; i < 10; i++) { console.log("achao") ruben(); } |

另外做点补充吧，再分享一个some函数，用于判断数组内是否有元素满足某条件的

判断数组中是否有元素包含y

judge判断数组中是否有元素包含z

|---------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 9 | hljs javascript var names = ['ruben', 'achao', 'zhangsan']; var result = names.some(name => name.indexOf("y") != -1) console.log(result) function judge(value) { return value.indexOf("z") != -1; } result = names.some(judge); console.log(result) |

输出结果
