這篇文章主要介紹了JS實(shí)現(xiàn)的五級(jí)聯(lián)動(dòng)菜單效果,結(jié)合完整實(shí)例形式分析了js多級(jí)聯(lián)動(dòng)菜單的完整實(shí)現(xiàn)步驟,涉及JS數(shù)組遍歷、擴(kuò)展及元素節(jié)點(diǎn)操作相關(guān)技巧,需要的朋友可以參考下

本文實(shí)例講述了JS實(shí)現(xiàn)的五級(jí)聯(lián)動(dòng)菜單效果。分享給大家供大家參考，具體如下：

js實(shí)現(xiàn)多級(jí)聯(lián)動(dòng)的方法很多，這里給出一種5級(jí)聯(lián)動(dòng)的例子，其實(shí)可以擴(kuò)展成N級(jí)聯(lián)動(dòng),在做項(xiàng)目的時(shí)候碰到了這樣一個(gè)問題但是有不能從數(shù)據(jù)庫(kù)中動(dòng)態(tài)的加載這些選項(xiàng)，所以只有想辦法從單個(gè)的頁(yè)面著手來(lái)處理了，應(yīng)為項(xiàng)目的表單是動(dòng)態(tài)產(chǎn)生的，所以需要每個(gè)流程的設(shè)計(jì)過程中需要有單獨(dú)的頁(yè)面來(lái)處理，這樣就決定了不能改變已有的業(yè)務(wù)邏輯來(lái)實(shí)現(xiàn)多級(jí)表單的聯(lián)動(dòng)。

運(yùn)行效果圖如下：
