本文實(shí)例為大家分享了js實(shí)現(xiàn)懸浮窗的具體代碼，供大家參考，具體內(nèi)容如下
說(shuō)明：點(diǎn)擊”+“按鈕，懸浮窗收縮/展開(kāi)
思路
1、在html中定義一個(gè)div塊，定一個(gè)id；一個(gè)按鈕，點(diǎn)擊時(shí)用。
2、寫一個(gè)js,包含收縮以及展開(kāi)的函數(shù)；為按鈕添加點(diǎn)擊事件。
3、想要讓懸浮窗好看點(diǎn)，可設(shè)置對(duì)應(yīng)的參數(shù)。
步驟
html
<div id="area"> <div id="small_menu"> <ul> <li><a href="#">item one</a></li> <li><a href="#">item two</a></li> <li><a href="#">item three</a></li> <li><a href="#">item four</a></li> <li><a href="#">item five</a></li> </ul> </div> <div id="on" onclick="xuanfu();"><p>+</p></div> </div>
js
var menubox = document.getElementById("area"); //area為菜單欄的id var cli_on = document.getElementById("on"); //on為按鈕 var flag = false, timer = null, initime = null, r_len = 0; if(menubox.style.right=== 0){ flag = true; } else{ flag = false; } cli_on.onclick = function () { //為on按鈕綁定click事件 clearTimeout(initime); //根據(jù)狀態(tài)flag執(zhí)開(kāi)展開(kāi)收縮 if (flag) { r_len = 0; timer = setInterval(slideright, 10); } else { r_len = -160; timer = setInterval(slideleft, 10); } } //展開(kāi) function slideright() { if (r_len <= -160) { clearInterval(timer); flag = !flag; return false; }else{ r_len -= 5; menubox.style.right = r_len + 'px'; } } //收縮 function slideleft() { if (r_len >= 0) { clearInterval(timer); flag = !flag; return false; } else { r_len += 5; menubox.style.right = r_len + 'px'; } } 完整代碼
