Losing the data while iterating the table by Rows with Java & JSP

In the jsp page, depending on the number of records, this tr will be executed and displayed to the users.

for(int i=0; i<NoOfRecords.length;i++){
<tr>
    <td width="15%"> Transit Account & <%= acctId%>
    </td>
    <td width="15%"> <%=MultiModeConstants.GL_ACCT_NO%>
    </td>
    <td width="45%">
    <input type="text" id="multiModeAcctNo" name="multiModeAcctNo" desc="Multi Mode Transit Account Number" maxlength="9" class="body" size="9" tabindex="3" >
    </td>
    <td width="15%">
        Deposit
    </td>
    <td width="15%">
        $ <%= transactioAmount%>
    </td>
&l开发者_运维知识库t;/tr>
}

Based on the number of records, Number of rows would be populated in the jsp page, multiModeAcctNo, field will be entered by User(multiModeAcctNo);

For example if there are 4 records, there are 4 times I enter different multiModeAcctNo in the page.

After submitting the page, I am able to get only the first field, I am losing the other 3 values.

Suppose if I only read One Row, then I am able to get the data fine. What do I need to do?

I am using java & jsp as the programming languages.


You have to create dynamic names for input fields may be as:

for(int i=0; i<NoOfRecords.length;i++){
<tr>
    <td width="15%"> Transit Account & <%= acctId%>
    </td>
    <td width="15%"> <%=MultiModeConstants.GL_ACCT_NO%>
    </td>
    <td width="45%">
    <input type="text" id="multiModeAcctNo_<%=i%>" name="multiModeAcctNo_<%=i%>" desc="Multi Mode Transit Account Number" maxlength="9" class="body" size="9" tabindex="3" >
    </td>
    <td width="15%">
        Deposit
    </td>
    <td width="15%">
        $ <%= transactioAmount%>
    </td>
</tr>
}

Now in your servlet [hoping that you also get NoOfRecords.length there] get value of each input by providing it's dynamically generated names. May be as:

String str = new String[NoOfRecords.length];
for(int i=0; i<NoOfRecords.length;i++){
    str[i] = request.getParameter("multiModeAcctNo_"+i);
}


I'm not sure what kind of submission you're doing but you may want to use a different ID for your input field, as you iterate you are using the same multiModeAcctNo ID in your <input>.

If you're using a form and POSTing the element you may want to name your input to something like multiModeAcctNo[] then in your JSP file refer it as a POST array element (not sure if that's possible with Java). Just an idea.
