本文实例讲述了JS+CSS实现可拖动的弹出提示框。分享给大家供大家参考。具体实现方法如下： 复制代码 代码如下: JS+CSS打造的可拖动的弹出提示框 <br /> a{ color:#000; font-size:12px;text-decoration:none}<br /> a:hover{ color:#900; text-decoration:underline}<br /> body{background:;filter:progid:DXImageTransform.Microsoft.Gradient(gradientType=0,startColorStr=#ffffff,endColorStr=#003366); overflow:hidden}<br /> #massage_box{ position:absolute; left:expression((body.clientWidth-350)/2); top:expression((body.clientHeight-200)/2); width:350px; height:200px;filter:dropshadow(color=#666666,offx=3,offy=3,positive=2); z-index:2; visibility:hidden}<br /> #mask{ position:absolute; top:0; left:0; width:expression(body.scrollWidth);height:expression(body.scrollHeight); background:#666; filter:ALPHA(opacity=60); z-index:1; visibility:hidden}<br /> .massage{border:#036 solid; border-width:1 1 3 1; width:95%; height:95%; background:#fff; color:#036; font-size:12px; line-height:150%}<br /> .header{background:#036; height:10%; font-family:Verdana, Arial, Helvetica, sans-serif; font-size:12px; padding:3 5 0 5; color:#fff}<br /> <br /> var Obj=''<br /> document.onmouseup=MUp<br /> document.onmousemove=MMove<br /> function MDown(Object){<br /> Obj=Object.id<br /> document.all(Obj).setCapture()<br /> pX=event.x-document.all(Obj).style.pixelLeft;<br /> pY=event.y-document.all(Obj).style.pixelTop;<br /> } <p>function MMove(){<br /> if(Obj!=''){<br /> document.all(Obj).style.left=event.x-pX;<br /> document.all(Obj).style.top=event.y-pY;<br /> }<br /> } <p>function MUp(){<br /> if(Obj!=''){<br /> document.all(Obj).releaseCapture();<br /> Obj='';<br /> }<br /> }<br /> × 点此提示 希望本文所述对大家的javascript程序设计有所帮助。
