Ex:
string1=”d.o.t”
findString=”.o”
repString = “o”
string2 = MyReplaceMethod(string1,findString,repString)
then string2 must be “do.t”

findString=”.”
repString = “”
string2 = MyReplaceMethod(string1,findString,repString)
then string2 must be “dot”

examples corrected

Thank you

I want to write a method which replaces all the places in a given string.

Ex:
string1=”d.o.t”
findString=”.o”
repString = “o”
string2 = MyReplaceMethod(string1,findString,repString)
then string2 must be “do.t”

repString = “”
string2 = MyReplaceMethod(string1,findString,repString)
then string2 must be “dot”

I tried to use regex but it is having many problems, it uses some characters as special characters which cannot be used in the find string, like .,[,\,* etc.
So how to replace using regex if find string contains these special characters

Without using regex, I was able to do
1. split the string with find string
2. append them back using the replace string in the middle

This works but i want a procedure which uses regex and works with any type of characters

Thank you
Madhu

use the + to denote you want one or more of either char in the charclass. it reads well too. sometimes the pipe is easy to overlook.

loremTEXT2 = loremTEXT.replace(/[\r\n]+/g, “\n”);

Nice,

Adding on to what Jason said, Mac OS 9 and lower computers use only carraige returns (“\r”) for a newline characters so you can even do it this way as well.

`loremTEXT.replace(/\r\n|\r/gm, “\n”);`

using the pipe, “|”, character will check for “\r\n” or “\r” and replace with “\n”.

Using a character class there means that you’ll replace either \r OR \n with \n, and thus you’ll still have double line returns in Flex. Remove the [] so it’s just
`loremTEXT.replace(/\r\n/gm, “\n”);`
To convert line endings from Windows style to Unix style.

speps,

Great tip, thanks!
That’s a much better solution than my temporary RegExp object.

loremTEXT2 = loremTEXT.replace(/[\\r\\n]/g, "\\n");
