    IF u want to enhance this, place a javascript for loop in the generateRow function and iterate and generate the textboxes on One click of the add button

    Thank You

    Re: Struts Framework

    generateTextBoxes.jsp
    < html >
    < body >
    < form name="textBoxesForm" method="post" action="textBoxesAction.do" >
    < table >
    < TR >
    < TD >Quantity:< /TD >
    < TD >< input type=text name="textbox" >< /TD >
    < TD >SomeCode:< /TD > < TD >< input typ="txt" name="somecode">< /TD >
    < /TR >
    < TR >
    < TD >< input type="submit" value="Add Buttons" / >< /TD >
    < /TR >
    < % if (request.getAttribute("noOfTextBoxes")!=null) {
    int noOfBoxes = Integer.parseInt((String)request.getAttribute("noOfTextBoxes"));
    for(int i=0;i < noOfBoxes; i++){ % >
    < input type="txt' name="txtbox < %i% >" >
    < % }
    } % >
    < table >

    < body >
    < /html >

    //In the Action Class
    set a value,in the request attribute specifying the no of textboxes u want
    Make it as a string
    request.setAttribute("noOfTextBoxes","10");
    and again redirect to the the same page in struts-config.xml
    < action path="/someAction" forward ="jsps/generateTextBoxes.jsp" >
    < /action >
    This shows you how to generate text boxes
    By default when u load this page, there wont be any text boxes, after you click on the submit button , the request attribute "noOfTextBoxes" will be set to a value in the action class or a servlet and since you are redirecting the page again to the same page, then the request attribute will be having a value of 10 and thus generates the text boxes.

    Pls let me know your questions

    Note: I gave wrong intentionally in input tag of text box, otherwise it is displaying the text box in the post

    Thank You,
