js选项卡的问题 解决一个页面不能用两个选项卡
//JS代码：
function tabOn(tabid,a) {
for (i=1;i<=10;i++) {
if(i<10){inn="0"+i;} else {inn=""+i;}
tabMenu = document.getElementById("tab"+tabid+"m"+i);

我复制一份HTMl到另一个地方后 新的就不能切换了

------解决方案--------------------

这代码看得人那叫一个蛋疼
[解决办法]

JScript code

function tabOn(tabid,a) {for (i=1;i<=10;i++) {if(i<10){inn="0"+i;} else {inn=""+i;}tabMenu = document.getElementById("tab"+tabid+"m"+i);tabContent = document.getElementById("tab"+tabid+"c"+i);tabMore = document.getElementById("tab"+tabid+"more"+i);if (tabMenu) {if (tabMenu.tagName=="IMG") { tabMenu.src = tabMenu.src.replace("on.gif", ".gif"); }  if (tabMenu.tagName=="A") { tabMenu.className=""; }  }if (tabContent) { tabContent.style.display="none"; }if (tabMore) { tabMore.style.display="none"; }}if(a<10){ann="0"+a;} else {ann=""+a;}tabMenu = document.getElementById("tab"+tabid+"m"+a);tabContent = document.getElementById("tab"+tabid+"c"+a);tabMore = document.getElementById("tab"+tabid+"more"+a);//    alert(tabMenu.tagName);if (tabMenu) {if (tabMenu.tagName=="IMG") { tabMenu.src = tabMenu.src.replace(".gif", "on.gif"); }  if (tabMenu.tagName=="A") { tabMenu.className="on"; }  }if (tabContent) { tabContent.style.display="block"; }if (tabMore) { tabMore.style.display="block"; }}function imgMenuOver(containderID) {var objwrap = document.getElementById(containderID);var imgMenu = objwrap.getElementsByTagName("a");for (i=0; i<imgMenu.length; i++) {if(imgMenu[i].getElementsByTagName("img").length == 0) continue;if (imgMenu[i].getElementsByTagName("img")[0].src.indexOf("_on.gif") != -1 ) {continue;}imgMenu[i].onmouseover = function() {subImage = this.getElementsByTagName("img")[0];if (subImage.src.indexOf("_on.gif") != -1) return false;subImage.src = subImage.src.replace("_off.gif","_on.gif");}imgMenu[i].onfocus = function() {subImage = this.getElementsByTagName("img")[0];if (subImage.src.indexOf("_on.gif") != -1) return false;subImage.src = subImage.src.replace("_off.gif","_on.gif");}imgMenu[i].onmouseout = function() {subImage = this.getElementsByTagName("img")[0];subImage.src = subImage.src.replace("_on.gif", "_off.gif");}imgMenu[i].onblur = function() {subImage = this.getElementsByTagName("img")[0];subImage.src = subImage.src.replace("_on.gif", "_off.gif");}}}
