toString Method

Returns a string representation of an object.

function toString( [radix : Number] ) : String

Arguments

• radix
  Optional. Specifies a radix for converting numeric values to strings. This value is only used for numbers.

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".
Date	Returns the textual representation of the date.
Error	Returns a string containing the associated error message.
Function	Returns a string 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.

Example

The following example illustrates the use of the toString method with a radix argument. The return value of function shown below is a Radix conversion table.

function CreateRadixTable (){
   var s = "";

   // Create table heading.
   s += "Hex  Dec  Bin \n";

   for (x = 0; x < 16; x+)
   {
      s += "   ";

      // Convert to hexidecimal.
      s += x.toString(16);
      s += "     ";
      if (x < 10) s += "  ";

      // Convert to decimal.
      s += x.toString(10);
      s += "     ";

      // Convert to binary.
      s += x.toString(2);
      s += "\n";
   }

   return(s);
}
