本篇文章主要是對(duì)js鼠標(biāo)移動(dòng)顯示圖片的簡(jiǎn)單實(shí)例進(jìn)行了介紹，需要的朋友可以過(guò)來(lái)參考下，希望對(duì)大家有所幫助

一、js代碼

復(fù)制代碼代碼如下:

//***********默認(rèn)設(shè)置定義.*********************
tPopWait=50;//停留tWait豪秒后顯示提示。
tPopShow=5000;//顯示tShow豪秒后關(guān)閉提示
showPopStep=20;
popOpacity=99;

//***************內(nèi)部變量定義*****************
sPop=null;
curShow=null;
tFadeOut=null;
tFadeIn=null;
tFadeWaiting=null;

document.write("<mce:style type='text/css'id='defaultPopStyle'></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 mce_style="position:absolute;z-index:1000;"></div>");

function showPopupText(){
var o=event.srcElement;
    MouseX=event.x;
    MouseY=event.y;
    if(o.alt!=null && o.alt!=""){o.dypop=o.alt;o.};
        if(o.title!=null && o.title!=""){o.dypop=o.title;o.};
    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;
