The toString method is use to get 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. |
radix |
Optional. Specifies a radix for converting numeric values to strings. |
Return String
Returns a string representation of an object.
Example
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" |
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:
<HTML>
<HEAD>
<SCRIPT LANGUAGE= JavaScript>
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 = " ";
break;
}
document.write(" ", x.toString(16), s1, x.toString(10), s2, s3, x.toString(2), "</br>");
}
}
</SCRIPT>
</HEAD>
<BODY>
<SCRIPT LANGUAGE=JavaScript>
CreateRadixTable ();
