How to split HTML textarea element into array of lines in Java

Answer 1

If you mean Java and not Javascript (assuming you have a JSP system):

String[] lines = myTextArea.getText().split("\\n");

or

String[] lines = request.getParameter("textarea").split("\\n");

---

Edited down:

For javascript:

var lines = document.getElementById("myTextArea").value.split('\\n');

Answer 2

In Java, get the text and pass it to a method like:

private String[] split(String s) {
        if (s==null) {
            return new String[0];
        }

        StringTokenizer st = new StringTokenizer(s,"\n");
        ArrayList list = new ArrayList();
        while (st.hasMoreElements()) {
            list.add(st.nextToken());
        }

        return (String[]) list.toArray(new String[list.size()]);
}
