toString

Summary

Returns a string representation of an object.

Syntax

objectname.toString([ radix ])

objectname: Required. An object for which a string representation is sought.
radix: Optional. Specifies a radix for converting numeric values to strings. This value is only used for numbers.

Examples

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);
 }

Remarks

The toString method is a member of all built-in JavaScript 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:Copy Code 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.
