本篇文章主要是對js鼠標移動顯示圖片的簡單實例進行了介紹，需要的朋友可以過來參考下，希望對大家有所幫助
一、js代碼 代碼如下: //***********默認設置定義.********************* tPopWait=50;//停留tWait豪秒後顯示提示。 tPopShow=5000;//顯示tShow豪秒後關閉提示 showPopStep=20; popOpacity=99; //***************內部變量定義***************** sPop=null; curShow=null; tFadeOut=null; tFadeIn=null; tFadeWaiting=null; document.write("<mce:style type='text/css'id='defaultPopStyle'><!-- "); document.write(".cPopText { line-break : normal;word-break : break-all ; background-color: #FEFCF3;color:#000000; border: 1px #E7B68C solid;padding-top: 2px; padding-right: 4px; padding-left: 4px; padding-bottom: 2px;font-size: 12px;width:96px; filter: Alpha(Opacity=0)}"); document.write(" --></mce:style><style type='text/css'id='defaultPopStyle' mce_bogus="1">"); document.write(".cPopText { line-break : normal;word-break : break-all ; background-color: #FEFCF3;color:#000000; border: 1px #E7B68C solid;padding-top: 2px; padding-right: 4px; padding-left: 4px; padding-bottom: 2px;font-size: 12px;width:96px; filter: Alpha(Opacity=0)}"); document.write("</style>"); document.write("<div id='dypopLayer' style="position:absolute;z-index:1000;" mce_style="position:absolute;z-index:1000;" class='cPopText'></div>"); function showPopupText(){ var o=event.srcElement; MouseX=event.x; MouseY=event.y; if(o.alt!=null && o.alt!=""){o.dypop=o.alt;o.alt=""}; if(o.title!=null && o.title!=""){o.dypop=o.title;o.title=""}; if(o.dypop!=sPop) { sPop=o.dypop; clearTimeout(curShow); clearTimeout(tFadeOut); clearTimeout(tFadeIn); clearTimeout(tFadeWaiting); if(sPop==null || sPop=="") { dypopLayer.innerHTML=""; dypopLayer.style.filter="Alpha()"; dypopLayer.filters.Alpha.opacity=0; } else { if(o.dyclass!=null) popStyle=o.dyclass else popStyle="cPopText"; curShow=setTimeout("showIt()",tPopWait); } } } function showIt(){ dypopLayer.className=popStyle; dypopLayer.innerHTML=sPop; popWidth=dypopLayer.clientWidth; popHeight=dypopLayer.clientHeight; if(MouseX+12+popWidth>document.body.clientWidth) popLeftAdjust=-popWidth-24 else popLeftAdjust=0; if(MouseY+12+popHeight>document.body.clientHeight) popTopAdjust=-popHeight-24 else popTopAdjust=0; dypopLayer.style.left=MouseX+12+document.body.scrollLeft+popLeftAdjust; dypopLayer.style.top=MouseY+12+document.body.scrollTop+popTopAdjust; dypopLayer.style.filter="Alpha(Opacity=0)"; fadeOut(); } function fadeOut(){ if(dypopLayer.filters.Alpha.opacity<popOpacity) { dypopLayer.filters.Alpha.opacity+=showPopStep; tFadeOut=setTimeout("fadeOut()",1); } else { dypopLayer.filters.Alpha.opacity=popOpacity; tFadeWaiting=setTimeout("fadeIn()",tPopShow); } } function fadeIn(){ if(dypopLayer.filters.Alpha.opacity>0) { dypopLayer.filters.Alpha.opacity-=1; tFadeIn=setTimeout("fadeIn()",1); } } document.onmouseover=showPopupText; 二、html代碼包含js代碼即可，使用范例 <a href="../UpLoadFile/200911784060017.jpg" target="_blank" title="<img src=../UpLoadFile/200911784060017.jpg />">大</a> <a href="../UpLoadFile/200911784060018.jpg" target="_blank" title="<img src=../UpLoadFile/200911784060018.jpg width=96 height=70 />">小</a>
