Replace a character in the string using JavaScript

FYI, Steve L Walker​'s original code:

    this.rawValue = str.replace(/\s/,"\n");

Actually replaces any whitespace "\s" character with a newline "\n" character, not a carriage return "\r" character as stated in the answer and requested by the OP. While the newline character the OP got is likely what they actually needed, an OSX and Linux end-of-line sequence, the statements seem to indicate the opposite has occurred.

To replace any whitespace "\s" character with a carriage return "\r" character, use an "\r" instead of a "\n":

    this.rawValue = str.replace(/\s/,"\r");

Note: This is a valid end-of-line sequence for legacy Mac systems, but not for any modern OS. DOS and Windows use "\r\n", while Linux and OSX use "\n".

To replace any whitespace "\s" character with a carriage return "\r" character AND a newline "\n" character (a Windows end-of-line sequence) use an "\r\n":

    this.rawValue = str.replace(/\s/,"\r\n");

Thanks a lot. I will try this as well.

You could also use the global match attribute of the RegExp ... that is the "g" placed after the RegExp

.replace(/ü/g,"ue")

Steve,

Thanks a lot for this example.

It looks that I will need to use this for my current project and use a lot of it.

Thanks again.

Ilya.

This will handle multiple occurences of  "ü".

var str = this.rawValue;
var wordArray = str.split("ü");
var wordIndex = wordArray.length - 1;
str = "";
for (i=0; i < wordIndex; i++) {
    str += wordArray[i] + "ue";
}
this.rawValue = str + wordArray[wordIndex];

I used this approach to replace one of the purposely embedded character '~' into the XML file during the XSLT transformation and replace it using JavaScript with the carriage return.

Thank you.

Huh?

I didn't post my script...

It sure is no clean programming since I just took Steve's solutions and delted the ligns I didn't want (the app allert)

Though in the end I've taken the boolean out, or better replaced it with the replacement function, it repeats the replacement no matter how much "ü"'s are in there. (I needed the boolean though, since as long as it was true, the if should be executed.)

Somehow it worked... not 100% sure why, but it worked.

if (findChar(this.rawValue)) {
   

}

function findChar(str)

{  for (var i=0; i < str.length; i++)

     {
        if (str.charAt(i) == "ü")

          {
           this.rawValue = this.rawValue.replace(/ü/,"ue")
          }
     }

}

Lisa,

Thanks a lot. It worked.

Regards,

Ilya.

Find a single character and replace it with a string

var str = this.rawValue;
var wordArray = str.split("ü");
this.rawValue = wordArray[0] + "ue" + wordArray[1];

Didn't work, when the same char was more than one time in the field.

But the bolean did the job.

Thanx

Lisa

Steve,

Thanks a lot. I will try this one as well.

Best regards,

Ilya.
