Methods

Constructor

String String (value: any)
Returns a string representation of the value given as an argument.

Parameter	Type	Description

Example

new String(value)

Class

String fromCharCode (value1: number)
Returns a string created by concatenation one or more characters specified as ASCII values.

Parameter	Type	Description
value1	number	One or more ASCII values.

Example

String.fromCharCode(value1,...valueN)

Instances

string anchor (name: string)
Returns a string consisting of this string enclosed in a <a> tag.

Parameter	Type	Description
name	string	The text to be stored in the anchors' name attribute.

string big ()
Returns a string consisting of this string enclosed in a <big> tag.

string blink ()
Returns a string consisting of this string enclosed in a <blink> tag.

string bold ()
Returns a string consisting of this string enclosed in a tag.

string charAt (index: number)
Returns the character at the specified index.

Parameter	Type	Description
index	number	An integer between 0 and string.length -1, specifying the character to return.

Example

string.charAt(index)

number charCodeAt (index: number)
Returns the Unicode value of the character at the given index.

Parameter	Type	Description
index	number	An integer between 0 and string.length -1, specifying the character.

Example

string.charCodeAt(index)

string concat (value: string)
If necessary, converts the one or more given values to strings.
Those values are concatenated with the original string, the result is returned. The original string is not effected. Returns the concatenated string.

Parameter	Type	Description
value	string	The values to be concatenated with the given string.

Example

string.concat(value1,...valueN)

string fixed ()
Returns a string consisting of this string enclosed in a <tt> tag.

string fontcolor (color: string)
Returns a string consisting of this string enclosed in a tag.

Parameter	Type	Description
color	string	The value to be stored in the tag's color attribute.

string fontsize (size: number)
Returns a string consisting of this string enclosed in a tag.

Parameter	Type	Description
size	number	The value to be stored in the tag's size attribute.

number indexOf (searchValue: string[, offset: number])
Returns the index within the string of the first occurrence of the specified string, starting the search at fromIndex if provided.

Parameter	Type	Description
searchValue	string	The string for which to search.
offset	number	The starting offset of the search. (Optional)

Example

string.indexOf(searchValue, fromIndex)

string italics ()
Returns a string consisting of this string enclosed in a tag.

number lastIndexOf (searchValue: string[, offset: number])
Returns the index within the string of the last occurrence of the specified value.
The string is searched backward, starting at fromIndex. Returns the index within the string where the last occurrence of searchValue was found, or -1 if it was not found.

Parameter	Type	Description
searchValue	string	The string for which to search.
offset	number	The starting offset of the search. (Optional)

Example

string.lastIndexOf(searchValue, fromIndex)

string link (href: string)
Returns a string consisting of this string enclosed in a <a> tag.

Parameter	Type	Description
href	string	The value to be stored in the tag's href attribute.

number localeCompare (what: string)

string replace (what: any, with: string)

Parameter	Type	Description
what	any
with	string

number search (search: RegExp)

Parameter	Type	Description
search	RegExp

string slice (startSlice: number[, endSlice: number])
Extracts a substring of the given string and returns it as a new string.
The substring begins at startSlice, and includes all characters up to, but not including the character at the index endSlice. A negative value indexes from the end of the string. For example, a negative value for startSlice is resolved as: string. length + startSlice. The original string is unchanged. Returns a substring of characters from the given string, starting at startSlice and ending with endSlice-1.

Parameter	Type	Description
startSlice	number	The index at which to begin extraction.
endSlice	number	The index at which to end extraction. If omitted, slice extracts to the end of the string. (Optional)

Example

string.slice(startSlice, endSlice)

string small ()
Returns a string consisting of this string enclosed in a tag.

string split (delimiter: string, limit: number)
Splits a string into a group of substrings, places those strings in an array, and returns the array.
The substrings are created by breaking the original string at places that match delimiter, the delimiter characters are removed. Returns an array whose elements are the substrings.

Parameter	Type	Description
delimiter	string	Specifies the string to use for delimiting. If delimiter is omitted, the array returned contains one element, consisting of the entire string.
limit	number

Example

string.split(delimiter)

string strike ()
Returns a string consisting of this string enclosed in a <strike> tag.

string sub ()
Returns a string consisting of this string enclosed in a tag.

string substr (start: number, length: number)
Returns a string containing the characters beginning at the specified index, start, through the specified number of characters.
The original string is unchanged. Returns a string containing the extracted characters.

Parameter	Type	Description
start	number	Location at which to begin extracting characters.
length	number	(OptIonal) The number of characters to extract.

Example

string.substr(start, length)

string substring (indexA: number[, indexB: number])
Returns a substring of the given string by extracting characters from indexA up to but not including indexB.
The original string is unchanged. Returns a substring of characters from the given string, starting at indexA and ending with indexB-1.

Parameter	Type	Description
indexA	number	The index to begin extracting.
indexB	number	(Optional) The index at which to end extraction. If omitted, slice extracts to the end of the string.

Example

string.substring(indexA, indexB)
