concat Method (String) (Windows Scripting - JScript)

Updated: March 2009

Returns a string value containing the concatenation of two or more supplied strings.

                      string1.concat([string2[, string3[, . . . [, stringN]]]])


Required. The String object or literal to which all other specified strings are concatenated.

string2,. . ., stringN

Optional. String objects or literals to concatenate to the end of string1.

The result of the concat method is equivalent to: result = string1 + string2 + string3 + + stringN. A change of value in either a source or result string does not affect the value in the other string. If any of the arguments are not strings, they are first converted to strings before being concatenated to string1.

The following example illustrates the use of the concat method when used with a string:

function concatDemo()
   var str1 = "ABCD"
   var str2 = "EFGH";
   var str3 = "1234";
   var str4 = "5678";
   var s = str1.concat(str2, str3, str4);
   // Output: "ABCDEFGH12345678"
