<img id="pic1" src="images/sm_02.gif" onclick="myClick(this.id);"/>
<img id="pic2" src="images/sm_02.gif" onclick="myClick(this.id);"/>

click.js代碼：
var click_status;
var clicked_ID;
var clicked_path;
function myClick(id){
if(click_status==1){
if(clicked_ID=="pic1"){
document.getElementById(clicked_ID).src = "images/sm_02.gif";
change(id);
}
if(clicked_ID=="pic2"){
document.getElementById(clicked_ID).src = "images/sm_02.gif";
change(id);
}
}else{
change(id);
}
}
function change(id){
click_status = 1;
var id = id;
clicked_ID = id;
var path = document.getElementById(id).src;
clicked_path = path;
if(id=="pic1"){
document.getElementById(id).src = "images/scan.gif";
}
if(id=="pic2"){
document.getElementById(id).src = "images/scan.gif";
