Question

I try to generate some square matrix, and need to send data in post method, I found solution with javascript and form, but all time new form create new line. Othervise I move opening form block out of iteration but it make just 1 variable when i presed on any number, it send always 1 in “place” field.

<%
        for (int i = 1; i <= 20; i++) { %>

            <form name="submitForm" method="POST" action="buy">
            <%
                for (int j = 1; j <= 20; j++) {%>
                    <a href="javascript:;" onclick="parentNode.submit();"> <%=j%> </a>
                    <input type="hidden" name="row" value="<%=i%>"/>
                    <input type="hidden" name="place" value="<%=j%>"/>
                    <% if (j == 20) { %>
                        <p>
                    <%}%>
                <%}%>
            </form>
        <%}
%>

Answer 1

Use CSS to make sure the form displays as an inline element, not a block element which has a line-break before and after it.

<style>form { display: inline }</style>

or

<form name="submitForm" method="POST" action="buy" style="display:inline">

Some pitfalls are discussed in How to display HTML <FORM> as inline element? since the open <form> tag still implies the end of a paragraph element that otherwise appears to contain it.
