出问题的两行代码 在IE6下没问题，在现在的win7的 IE11 360 Firefox等浏缆器上会报错如下，请问各位大老要如何解决，谢谢
50行代码：
if(obj_td)obj_td.all[0].src="images/jan.gif"
menu.asp:50 Uncaught TypeError: Cannot read property '0' of undefined
at collapseAll (menu.asp:50)
at collapse (menu.asp:32)
at menu.asp:238
67行代码：
if (tds[i].background.indexOf("images/left_bg02.gif")>-1)
menu.asp:67 Uncaught TypeError: Cannot read property 'indexOf' of undefined
at td_bg (menu.asp:67)
at HTMLTableElement.onclick (menu.asp:117)
原生 js 啊
if (tds[i].style.background.indexOf("images/left_bg02.gif")>-1) // style 内设置的样式，通过 style 来读取和设置
{
tds[i].style.background="images/left_bg01.gif"
// 我调试了下，没发现 obj_td 是多个数据，仅仅就一个 td，不要用 all[0] 了，直接写
obj_td.src="images/jan.gif"
在IE6中，可能不会出现这些错误，但在现代浏览器中，它们可能会更严格地执行JavaScript规范。
在50行代码中，如果obj_td未定义，尝试读取其子元素all[0]将导致错误。可以使用if语句或三元运算符来检查obj_td是否为undefined或null，然后再尝试访问其子元素。
修改后的代码如下所示：
if (obj_td && obj_td.all) {
obj_td.all[0].src = "images/jan.gif";
}
在67行代码中，tds[i]的background属性可能未定义，因此在尝试调用其indexOf方法时会出现错误。可以使用if语句或三元运算符来检查tds[i]的background属性是否已定义，并且在尝试访问其子元素之前执行此操作。
修改后的代码如下所示：
if (tds[i] && tds[i].background && tds[i].background.indexOf("images/left_bg02.gif") > -1) {
// some code here
}
