JavaScript String method: replace()

[this page | pdf | back links]

The replace() method (when applied to a JavaScript string) returns a string that repeats a specified string a specified number of times.

 

It has the following syntax with the following parameters:

 

string.replace(searchvalue)

 

Parameter

Required / Optional

Description

searchvalue

Required

Value or regular expression to be replaced

newvalue

Required

New value inserted instead

 

If searchvalue is a normal string then only the first occurrence is replaced, if it occurs more than once in the string being searched. If you want to replace all occurrences then you need to use a corresponding regular expression with a /g, i.e. global, modifier.
