這篇文章主要介紹了Javascript實(shí)現(xiàn)的簡(jiǎn)單右鍵菜單類,通過JavaScript自定義類實(shí)現(xiàn)右鍵菜單功能,具有一定參考借鑒價(jià)值,需要的朋友可以參考下

本文實(shí)例講述了Javascript實(shí)現(xiàn)的簡(jiǎn)單右鍵菜單類。分享給大家供大家參考。具體如下：

這是自己寫的一個(gè)右鍵菜單類，屏蔽掉了IE固有的右鍵菜單，一共有四個(gè)參數(shù)：第一個(gè)是出發(fā)顯示右鍵菜單的div的id

第二個(gè)是右鍵菜單這個(gè)層的id，根據(jù)這個(gè)id去創(chuàng)建一個(gè)新的層，menuList是菜單項(xiàng)的列表，對(duì)應(yīng)了點(diǎn)擊一個(gè)菜單項(xiàng)后觸發(fā)的函數(shù)，classList是菜單的class名稱，以及菜單項(xiàng)對(duì)應(yīng)的class名稱，包含了鼠標(biāo)滑過時(shí)的class。

運(yùn)行效果截圖如下：
