toString Method

Returns a string representation of an object.

function toString( [radix : Number] ) : String
radix

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

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.

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 (var 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);
}
