本文实例讲述了JS实现的五级联动菜单效果。分享给大家供大家参考,具体如下:
js实现多级联动的方法很多,这里给出一种5级联动的例子,其实可以扩展成N级联动,在做项目的时候碰到了这样一个问题但是有不能从数据库中动态的加载这些选项,所以只有想办法从单个的页面着手来处理了,应为项目的表单是动态产生的,所以需要每个流程的设计过程中需要有单独的页面来处理,这样就决定了不能改变已有的业务逻辑来实现多级表单的联动。
运行效果图如下:
完整代码如下:
<html> <head> <title>级联</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <style> body,select { font-size:9pt; font-family:Verdana; } a { color:red; text-decoration:none; } a:hover { text-decoration:underline; } </style> <SCRIPT LANGUAGE="JavaScript"> function Dsy() { this.Items = {}; } Dsy.prototype.add = function(id,iArray) { this.Items[id] = iArray; } Dsy.prototype.Exists = function(id) { if(typeof(this.Items[id]) == "undefined") return false; return true; } function change(v) { var str="0"; for(i=0;i<v;i++) { str+=("_"+(document.getElementById(s[i]).selectedIndex-1)); }; var ss=document.getElementById(s[v]); with(ss) { length = 0; options[0]=new Option(opt0[v],opt0[v]); if(v && document.getElementById(s[v-1]).selectedIndex>0 || !v) { if(dsy.Exists(str)) { ar = dsy.Items[str]; for(i=0;i<ar.length;i++)options[length]=new Option(ar[i],ar[i]); if(v)options[1].selected = true;

P70系列延期,华为新旗舰将在下月发布
3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。
而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?
根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
