Hi Friend,
We are providing you two different code.Fro first one, we have used Javascript and for another one, we have used java.
1)
<html>
<script>
function funct(){
document.form.text2.value = document.form.text1.value.split(' ').length;
}
</script>
<form name="form" method="post">
<textarea name="text1" cols="15" rows="2" onkeyup="funct();"></textarea>
<br>
<input name="text2" type="text" value="" >
</form>
2)
<%@page language="java"%>
<%@page import="java.util.*"%>
<html>
<form method="post" action="textarea.jsp">
<textarea name="text" cols="15", rows="2"></textarea>
<input type="submit" value="submit">
</form>
</html>
<%String data=request.getParameter("text");
int count=0;
if(data!=null){
StringTokenizer tokenizer = new StringTokenizer(data," ");
while(tokenizer.hasMoreTokens()){
String next = tokenizer.nextToken();
count++;
}
}
String st=Integer.toString(count);
%>
<input type="text" value="<%=st%>">
Thanks
