java多行文本框显示,需要获取多行字符串以在文本框Java中显示

I have a requirement in my project.

I generate a comment string in javascript.

Coping Option: Delete all codes and replace

Source Proj Num: R21AR058864-02

Source PI Last Name: SZALAI

Appl ID: 7924675; File Year: 7924675

I send this to server where I store it as a string in db and then after that I retrieve it back and show it in a textarea.

I generate it in javascript as :

codingHistoryComment += 'Source Proj Num: '+'n';

codingHistoryComment += 'Source PI Last Name: '+'n';

codingHistoryComment += 'Appl ID: ; File Year: '+'n';

In java I am trying to replace the n to

:

String str = soChild2.getChild("codingHistoryComment").getValue().trim();

if(str.contains("\n")){

str = str.replaceAll("(rn|n)", "
");

}

However the textarea still get populated with the "n" characters:

Here is a test that works, try it out:

String str = "This is a testrn test.";

if(str.contains("rn")) {

System.out.println(str);

}
