The following functions can be used to manipulate and retrieve string details from objects and variables.

These should be written in the following formats:

• variable.method(arguments), example - myVar.subStr(3,2) if your variable name was "myVar" and you wanted to use subStr() to find the 2 characters that begin 3 from the left.

• object.method(arguments), example - city.coords.split(",") if you wanted to split the coordinates of your city into an array to determine the seperate x and y values using the split() function.

Methods

charAt

Usage: charAt(#)

Returns the character in the position specified by the index parameter.

Example:

• // Don't forget almost all internal "counting" starts at 0, not at 1...

• // so the 5th character would actually be 0, 1, 2, 3, 4 <--- 4!

• var="hello"
• echo "The 5th letter in the word hello is: " + var.charAt(4)

Result:

• 00:49:44 The 5th letter in the word hello is: o
• 00:49:45 Script stopped

charCodeAt

Usage: charCodeAt(#)

Returns the numeric Unicode character code of the character at the specified index.

Example:

• var="hello"
• echo "The numeric code of the 5th letter in the word hello is: " + var.charCodeAt(4)

Result:

• 01:04:27 The numeric code of the 5th letter in the word hello is: 111
• 01:04:28 Script stopped

concat

Usage: concat(arg1,arg2,...,argN)

Appends the supplied arguments to the end of the String object, converting them to strings if necessary, and returns the resulting string.

Example:

• var="oompa"
• var2="loompa"
• var3="dance"
• echo var.concat(var2," ",var3)

Result:

• 01:06:48 oompaloompa dance
• 01:06:49 Script stopped

fromCharCode

Usage:

Returns a string comprising the characters represented by the Unicode character codes in the parameters.

Searches the string and returns the position of the first occurrence of val found at or after startIndex within the calling string.

Example:

Result:

lastIndexOf

Usage:

Searches the string from right to left and returns the index of the last occurrence of val found before startIndex.

Example:

Result:

localeCompare

Usage:

Compares the sort order of two or more strings and returns the result of the comparison as an integer.

Example:

Result:

match

Usage:

Matches the specifed pattern against the string.

Example:

Result:

replace

Usage:

Matches the specifed pattern against the string and returns a new string in which the first match of pattern is replaced with the content specified by repl.

Example:

Result:

search

Usage:

Searches for the specifed pattern and returns the index of the first matching substring.

Example:

Result:

slice

Usage:

Returns a string that includes the startIndex character and all characters up to, but not including, the endIndex character.

Example:

Result:

split

Usage: split("delimiter")

Splits a String object into an array of substrings by dividing it wherever the specified delimiter parameter occurs.

Example:

• mycoords=city.coords.split(",")
• echo "x:" + mycoords[0] + " y:" + mycoords[1]

Result:

• 01:08:42 x:746 y:34
• 01:08:43 Script stopped
