client side validations on document having multiple forms & external jsp


Due to the long jsp page(limitations of Verify Error, loading time) , I have made 3 jsp files and included them in main jsp page using jsp action tags(dynamic/external jsp).

Main jsp page contains.

<jsp:include page="incECHeaderExt.jsp" flush="true" />

<jsp:include page="incTabsExt.jsp" flush="true" />

<jsp:include page="incPartItemsExt.jsp" flush="true" />

<%@ include file="incFooter.jsp" %>

Each jsp page is having its own form and controls.

Now in main page if user clicks a button (in incFooter.jsp), i need to validate input fields/dropdows,check boxes in the above three external files before calling server method.

Pl provide some sample code how can i access/call elements

of these external file forms to validate.

    For this you must use javascript.

    Here I give you an example:

    4 JSPs: otro.jsp, otro1.jsp, otro2.jsp, otro3.jsp

    • otro.jsp code:



    <center>Method getRemoteAddr sais: <%= request.getRemoteAddr() %><br></center>

    <jsp:include page="otro1.jsp" flush="true" />

    <jsp:include page="otro2.jsp" flush="true" />

    <%@ include file="otro3.jsp" %>



    • otro1.jsp code:

    <form name="otro1" method="post" action="tal">

    <input type="text" name="text1" size="30">


    • otro2.jsp code:

    <form name="otro2" method="post" action="tal">

    <input type="text" name="text2" size="30">


    • otro3.jsp code:

    <script language="JavaScript1.2">


    function hasClicked(){

    var formularios = document.forms;


    formularios<i>.elements[0].value="Someone has clicked the button!!!";

    //Note: elements[0] represents the first <input> element

    // or others elements in the form like <textarea>

    // <select> ...





    <form name="otro3" method="post" action="tal">

    <input type="text" name="text3" size="30"><br>

    <input type="button" value="myButton" onClick="hasClicked()">


    So the code in navigator is text/html, then you could access each form as they were on the same page.

      But all of the files use the htmlb forms with htmlb controls. Also pl tell me how to go about the controls of the each page in the JspDynpage.

      inputFld = (InputField) getComponentByName("input_EndOperatorValue"); is giving null

    I´ve had a similiar problem. Take a look at "Javascript Example isn´t working"

    SAP Enterprise Portal : Administration and Development

    Perhaps this helps you to access all htmlb elements
