<!DOCTYPE html> <html> <head> <title> ToString JavaScript </title> </head> <body> <h1> JavaScript ToString </h1> <script> var Str1 = "Tutorial Gateway"; var Str2 = 123.45; var Str3 = 4567; var Str4 = Str1.toString(); var Str5 = Str2.toString(); var Str6 = Str3.toString(); document.write(Str4 + "<br \>"); document.write(Str5 + "<br \>"); document.write(Str6 + "<br \>"); document.write(typeof(Str5) + "<br \>"); document.write(typeof(Str6) ); </script> </body> </html> |
OUTPUT
ANALYSIS
First we declared three String variables Str1, Str2, Str3 and assigned corresponding values using following statement
|
1 2 3 |
var Str1 = "Tutorial Gateway"; //String var Str2 = 123.45; //Float var Str3 = 4567; //Integer |
Following statements will convert the decimal and integer values to string values
|
1 2 3 |
var Str4 = Str1.toString(); var Str5 = Str2.toString(); var Str6 = Str3.toString(); |
Next, We used the JavaScript TypeOf Function, to show you the Data type of the variable. From the above screenshot you can observe that, data type of Str2 (decimal) and Str3 (integer) are converted to string type.

document.write(typeof(Str5) + "<br \>"); document.write(typeof(Str6) ); |
