Description
Returns a string representation of an object.
Syntax
objectname.toString([radix])

The toString method syntax has these parts:

Part Description
objectname Required. An object for which a string representation is sought.
radixOptional. Specifies a radix for converting numeric values to strings.

Remarks
The toString method is a member of all built-in JScript objects. How it behaves depends on the object type:

Object Behavior
Array Elements of an Array are converted to strings. The resulting strings are concatenated, separated by commas.
Boolean If the Boolean value is true, returns "true". Otherwise, returns "false"
Function Returns a string returned of the following form, where functionname is the name of the function whose toString method was called:
function functionname( ) { [native code] }
Number Returns the textual representation of the number.
String Returns the value of the String object.
Default Returns "[object objectname]", where objectname is the name of the object type.

The following example illustrates the use of the toString method with a radix argument:

function CreateRadixTable ()
{
  var s1, s2, s3, x;
  document.write("Hex    Dec   Bin<BR>");
  for (x = 0; x < 16; x++)
  {
    switch(x)
    {
      case 0 : 
        s1 = "      ";
        s2 = "    ";
        s3 = "   ";
        break;
      case 1 :
        s1 = "      ";
        s2 = "    ";
        s3 = "   ";
        break;
      case 2 :
        s3 = "  ";
        break;
      case 3 : 
        s3 = "  ";
        break;
      case 4 : 
        s3 = " ";
        break;
      case 5 :
        s3 = " ";
        break;
      case 6 : 
        s3 = " ";
        break;
      case 7 : 
        s3 = " ";
        break;
      case 8 :
        s3 = "" ;
        break;
      case 9 :
        s3 = "";
        break;
      default: 
        s1 = "     ";
        s2 = "";
        s3 = "    ";
    }
    document.write(" ", x.toString(16), s1, x.toString(10), s2, s3, x.toString(2), "<BR>");
  }
}
