Returns a string representation of an object.
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.
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 (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);
}
