js数组元素的随机调用 工作中网页填充数据时需要一个短语库,来拼接在短语句子后边.那就写一个js吧,放在input的keydown或keyup里边用喽. 贴代码: <SCRIPT LANGUAGE="JavaScript"> function AddSuffix(suf) { var test = ["abc","def","ghi","jkl"]; document.getElementByI…

这里整理了几个产生随机数的方法: 1.generateUUID() //获取一个唯一数 function generateUUID() { var d = new Date().getTime(); var uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function (c) { var r = (d + Math.random() * 16) % 16 | 0; d = Math.floor(d / 16); r…
