网站在Mozilla中完美运行，但在IE中则不然。 我的js文件与IE不兼容吗？

Question

I'm working on a site written in PHP/MySQL. We have a form to reserve time on a calendar and it works great in Mozilla and stores the reservation to our database, but in IE you fill out the form and when you click the "Reserve" button to submit it and nothing happens. All I can think of is that my javascript is not working with IE. I have these lines in my .js file:

 resLenT = document.getElementById(resLenElem);

 resLenI = resLenT.selectedIndex;
 resLen = resLenI + 1;

where resLenElem is a drop-down box. These are the only lines that I can think of at the moment that might be causing trouble in IE. Does this all sound like I'm on the right track or am I way off base?

Answer 1

try:

resLenT = document.getElementById("resLenElem");

notice the quotes around resLenElem
