You want to remove characters from a string and optionally replace them.
Create a custom String.sim
pleReplace(
)
method.
Alternatively, for replacing patterns, use
the String.rep
lace( )
method
included in RegExp.as.
ActionScript does not provide a native method that replaces
substrings within a string. Therefore, you must use a custom method
to do so. If you want to replace instances of a specific substring,
you can create a custom simpleReplace( )
method
for the String
class. This method should accept
up to three parameters:
search
The substring you want to find and replace.
replace
The value with which to replace the occurrences of the
search
substring.
matchCase
If true, the method performs a case-sensitive search. Otherwise, it performs a case-insensitive search.
Here is our custom String.simpleReplace( )
method:
String.prototype.simpleReplace = function (search, replace, working) { //temp
stores the string value with the replaced substrings. var temp; //working
holds the value of the string. var working = this; // Perform a case-insensitive search if so directed. if (!matchCase) { working = this.toLowerCase( ); search = search.toLowerCase( ); } //searchIndex
holds the starting index of a matches.startIndex
stores the value // of the index after the replaced substring. var searchIndex = -1; var startIndex = 0; // Find each match to the search substring. while ((searchIndex = working.indexOf(search, startIndex)) ...
