I deducted an effect from the blog website, but there is something I can't figure out. I asked Wuyouqiang to help me research it.
Demo now: http://www.iyumen.cn/TopUser.asp
Effect description: Put the mouse on the avatar, and the avatar will automatically transform into another picture. Because there are two formats of images on my website, gif and jpg, so now if the original image is jpg, there is no problem. If it is gif, there will be a prompt saying that the avatar has not been uploaded. In fact, there is, but there is no setting in the js to read it. Get the gif.

So, the function I want is to put the mouse on the picture without changing to another picture. Can this be done?

I have made the source code involved in this page into a compressed package to facilitate downloading and modification by experts. Maybe I didn't describe it very clearly.

Copy code The code is as follows:

function oo(obj){
        return typeof(obj)=="string"?document.getElementById(obj):obj
}

var eet,eel,bid,dh;
var state=0;
var showi=0;

function asdf_list(sign,id,user){
var xid=id.substr(0,id.length-5)

    bid=id;
    e=oo(bid)
// alert(name)
    var et=e.offsetTop;
    var el=e.offsetLeft;
    while(e=e.offsetParent){
        et+=e.offsetTop;
        el+=e.offsetLeft;
    }
    eet=et;
    eel=el;

    if(sign==1){
        if(showi==0){
            if(el<780){
//alert("<780")
