设置TextBox中光标的位置到最后(set the cursor position in a TextBox or InputText)

works in IE and FF

example：

< html  xmlns ="http://www.w3.org/1999/xhtml" >

< script  type ="text/javascript" >

function  clik()
{
     var  element = document.getElementById( ' element ' );  
     if  (document.all)
     {
         var  range =  element.createTextRange();
        range.collapse( false );
        range.select();
    } 
     else  {
        element.focus();
         var  v =  element.value;
        element.value =   '' ;
        element.value =  v;
   }
}


</ script >

< body >
     < form  id ="form1"  runat ="server" >
         < input  id ="element"  type ="text"   />
         < input  id ="Button1"  type ="button"  value ="Focus"  onclick ="clik();"   />
     </ form >
</ body >
</ html >
