Concat method Instance of a JavaScript string object (for connecting two or more strings) _ Basics

JavaScript Concat Method

The Concat method joins two or more strings with the following syntax:

Copy Code code as follows:

Str_object.concat (str1, str2, ...)

Str_object is the first string (object) that needs to be connected, str1 is the second string that needs to be connected, str2 is the third string that needs to be connected, and so on, at least one str1 is required.

Concat instance

Copy Code code as follows:

<script language= "JavaScript" >
var str = "www";
var str1 = ".";
var str2 = "jb51";
var str3 = ".";
var STR4 = "NET";
document.write (Str.concat (str1, str2, STR3, STR4));
</script>

Run the example and output:
Www.jb51.net
Tip: It is often easier to connect strings using the + operator, see also: JavaScript operator.
