oncontextmenu事件 在MAC版火狐浏览器下表现差异
谷歌和其它浏览器
//css *{margin:0;padding:0;} #right-menu{position:absolute;width:150px;visibility:hidden;border:1px solid #bababa;box-shadow: 1px 1px 2px #8e8e8e;} #right-menu li{list-style:none;text-indent:1em;} #right-menu li a{display:block;height:30px;line-height:30px;text-decoration:none;color:#666;font-size: 12px;} #right-menu li a:hover{background:#ebebeb;color:black;}//html //jsdocument.oncontextmenu = function(e){ if(window.event) e = window.event; var mymenu = document.getElementById("right-menu"); mymenu.style.visibility = "visible"; mymenu.style.left = e.clientX + 5 +"px"; mymenu.style.top = e.clientY + 5 + "px"; return false;//阻止右键系统默认的弹出框};document.onclick = function(){ var mymenu = document.getElementById("right-menu"); mymenu.style.visibility = "hidden"; }//除了火狐，oncontextmenu在其他浏览器上的交互 右键mouseup 执行事件//火狐是mousedown的时候执行 抬起消失 兼容写法
document.oncontextmenu = function(e){ return false;};document.onmouseup=function(e) { var mymenu = document.getElementById("right-menu"); if (!e) e=window.event; if (e.button==0) { mymenu.style.visibility = "hidden"; } if (e.button==2) { mymenu.style.visibility = "visible"; mymenu.style.left = e.clientX + 5 +"px"; mymenu.style.top = e.clientY + 5 + "px"; }}//思路 1.阻止默认事件2.mouseup 右键展示重写菜单 左键隐藏
