    The moveStart and moveEnd methods expects 2 parameters. The first parameter is a string (character, word, sentence or textedit). The second parameter is an integer and refers to the number of units to move. http://msdn.microsoft.com/en-us/library/ie/ms536623%28v=vs.85%29.aspx

    IE use different approach at setting cursor position than Firefox,Opera and Chrome. It's better to make a helper function, which will do it for you. I use this one for own needs.

    function setCursor(node,pos){
    
        node = (typeof node == "string" || node instanceof String) ? document.getElementById(node) : node;
    
        if(!node){
            return false;
        }else if(node.createTextRange){
            var textRange = node.createTextRange();
            textRange.collapse(true);
            textRange.moveEnd(pos);
            textRange.moveStart(pos);
            textRange.select();
            return true;
        }else if(node.setSelectionRange){
            node.setSelectionRange(pos,pos);
            return true;
        }
    
        return false;
    }
    

    Last thing, is to call it from your onfocus handler.

    Goodluck

    $("#textbox").selectionStart=14 might works for Firefox, Opera, Chrome, but not sure for IE

    PS: There should be length 14 > characters already in textbox to work properly.
