JQuery弹出层，点击按钮后弹出遮罩层，还有关闭按钮 <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>jQuery弹出层效果</title> <meta content="网页特效,特效代码,jQuery,css特效,Js代码" name="keywords" /> <meta content="jQuery弹出层效果，有关闭按钮，代码简单易懂，可以随意修改弹出层的参数。" name="description" /> <script src="/js/jquery-1.4.2.min.js" type="text/javascript"></script> <style> .black_overlay{ display: none; position: absolute; top: 0%; left: 0%; width: 100%; height: 100%; background-color: black; z-index:1001; -moz-opacity: 0.8; opacity:.80; filter: alpha(opacity=80); } .white_content { display: none; position: absolute; top: 10%; left: 10%; width: 80%; height: 80%; border: 16px solid lightblue; background-color: white; z-index:1002; overflow: auto; } </style> <script type="text/javascript"> //弹出隐藏层 function ShowDiv(show_div,bg_div){ document.getElementById(show_div).style.display='block'; document.getElementById(bg_div).style.display='block' ; var bgdiv = document.getElementById(bg_div); bgdiv.style.width = document.body.scrollWidth; // bgdiv.style.height = $(document).height(); $("#"+bg_div).height($(document).height()); }; //关闭弹出层 function CloseDiv(show_div,bg_div) { document.getElementById(show_div).style.display='none'; document.getElementById(bg_div).style.display='none'; }; </script> </head> <body> <input id="Button1" type="button" value="点击弹出层" onclick="ShowDiv('MyDiv','fade')" /> <!--弹出层时背景层DIV--> <div id="fade" class="black_overlay"> </div> <div id="MyDiv" class="white_content"> <div style="text-align: right; cursor: default; height: 40px;" id="move"> <span style="font-size: 16px;" onclick="CloseDiv('MyDiv','fade')">关闭</span> </div> 目前来说，我还是喜欢这个自己改造的弹出层。自己在项目中也用的是这个。 </div> </body> </html>
如果需要随意移动弹窗，可以在<script></script>中加入以下代码：
window.onload = function (){ var myDiv = document.getElementById("MyDiv"); var move = document.getElementById("move"); var bDrag = false; var disX = disY = 0; move.onmousedown = function (event){ var event = event || window.event; bDrag = true; disX = event.clientX - myDiv.offsetLeft; disY = event.clientY - myDiv.offsetTop; this.setCapture && this.setCapture(); return false; }; document.onmousemove = function (event){ if (!bDrag) return; var event = event || window.event; var iL = event.clientX - disX; var iT = event.clientY - disY; var maxL = document.documentElement.clientWidth - myDiv.offsetWidth; var maxT = document.documentElement.clientHeight - myDiv.offsetHeight; iL = iL < 0 ? 0 : iL; iL = iL > maxL ? maxL : iL; iT = iT < 0 ? 0 : iT; iT = iT > maxT ? maxT : iT; myDiv.style.marginTop = myDiv.style.marginLeft = 0; myDiv.style.left = iL + "px"; myDiv.style.top = iT + "px"; return false; }; document.onmouseup = window.onblur = move.onlosecapture = function (){ bDrag = false; move.releaseCapture && move.releaseCapture(); }; }
