Why don't you use the Javascript substr function rather than incrementally adding the characters to the variable? It takes the form: string.substr(start, n); where start is the starting character of the substring and n is the number of characters to return after this. Change your code to:

var n="";
str=document.getElementById("attach").value;
m=str.lastIndexOf("\\");
m++; //Increment the position of the last \\ so it is not included in the variable n.

n = str.substr(m, str.length-m);
document.getElementById("name").innerHTML = n;

alert(document.getElementById("name").innerHTML);

Tried in FF, Opera and IE and works in all. Regards, --Perspx

The reason it doesn't work in IE is because it doesnt like you doing: string[i] to return a character; try something like:

var s = "hello";

alert(s[0]);

and try it in IE and FF and note that it returns undefined in IE. The JavaScript standards are slightly different in IE and Mozilla-based browsers so this is why. If you wanted to return a character, the safe option would be: var character = string.substr(i, 1); where i is the character you want to return from string. Regards, --Perspx
