Returns the character at the specified index.

strObj.charAt(index)

Arguments

strObj

Required. Any String object or literal.

index

Required. Zero-based index of the desired character. Valid values are between 0 and the length of the string minus 1.

Remarks

The charAt method returns a character value equal to the character at the specified index. The first character in a string is at index 0, the second is at index 1, and so forth. Values of index out of valid range return an empty string.

Example

The following example illustrates the use of the charAt method:

function charAtTest(n){
   var str = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; // Initialize variable.
   var s;                                  // Declare variable.
   s = str.charAt(n - 1);                  // Get correct character
                                           // from position n – 1.
   return(s);                              // Return character.
}
