Replace a character in the string using JavaScript

The following script uses a regular expression to identify any white space "\s" character and replace it with a carriage return. You could replace the "\s" with the applicable expression for your special character. Place the expression between the two forward slashes.

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

Is there also a short possibility to search for a special character in a value?

Like if it contains an "a" = "true".

If it contains no "a" = "false".

I want to create a similar script with no variable.

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

Works for the first character, but not for the following ones. So I want to create a while function.

Steve,

Thanks a lot.

It worked.

Best regards,

Ilya.

Try these...

Find a character and return a boolean

if (findChar(this.rawValue)) {
    xfa.host.messageBox("Found 'a'.");
}

function findChar(str) {
    var foundChar = false;
    for (var i=0; i < str.length; i++) {
        if (str.charAt(i) == "a") {
            foundChar = true;
        }
    }
    return foundChar;
}

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];

Steve,

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

Best 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,

Thanks a lot. It worked.

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")
          }
     }

}

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.

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];
