Hi!!
i need to write a function that counts the number of names seperated by a '/'

for example if i write
aashish/ankush in a field
the number returned should be 2

thanks....

Hi
You can split the string with '/' and then you can get the length some thing like this

var names = "aashish/ankush";
var namesList = names.split('/');

namesList.length will return the count as 2

the second part of the problem is , that now i have to write a function
where in i can enter only 9 digit numbers and after every ninth digit a "/" is automatically entered
the number of numbers i can enter is the count returned by the split function

You can try this code -->

Just be careful when you modify this code...

I forgot to include some backSlash in line #88:
simply change the entire line to this : thisNumbers.value = numArray.join("/") + "/";

This can easily be done using the split() method.

Here is an example:

function splitNames(names) {
	return names.split("/").length;
}

var names = "aashish/ankush";
alert("There are " + splitNames(names) + " names in the names list.");

The split() function has one parameter, separator , which defines the character(s) that you want to divide the text between. You could change this to anything, such as #*# so that your names string is:

aashish#*#ankush

hi @ essential...
thanks for all the effort...........
but your code always seems so compliacted to me...
i am jus a newbie :(
my fault.........

well i wrote this, to insert a / after a number as many times as the value of countname...

var count=0    

function countrelease()
{
  //alert("count name is " + countname )
  var strname = document.forms[0].RELEASE.value;
  var length = strname.length
  
  length=length-9
   
 if(count != countname)
  { 
   if (length % 10 == 0)
     {
      
        strname=strname + "/" 
        
      document.forms[0].RELEASE.value= strname;
      count=count+1
     }
    
  }
  else 
   { 
   
   event.returnValue = false;
   }
  
  //break;


 }

the problem is if countname is 2

i can type 123456789/987654321/1

where as i want the output to be
123456789/987654321

i am calling this function on keypress event !

The first code that i've provided is a cross-browser script. This moded (or simplified) version of the script, is based on the method's that you have used, in your last posted code.
All codes is as follows:

Just use the below script:

function pad()
{
    var txt=document.getElementById('<%= txt.ClientID %>');
    if(txt.value.replace(/\//g,"").length%2==0 && txt.value.length>0)
       txt.value=txt.value+'/';
}
<asp:TextBox runat="server" ID="txt" onkeypress="pad()"></asp:TextBox>

Here i showed how you can add pad / after each 2 character. Modify in your way.
