Question

I need to hide a field on page load based on the value of a request attribute. I don’t want a ‘hidden’ field because I want to show it again. I don’t want to do this with javascript. How is this done with jsp tags?

Answer 1

Set a condition where display is block if the condition is true. Else if the condition is false set the display to none.

<c:set var="inputDisplay" value="1" /> <!-- This same as your request attribute -->
<c:choose>
    <c:when test="${inputDisplay == 1}">
        <input type="text" />
    </c:when>
    <c:otherwise>
        <input type="text" style="display:none;" />
    </c:otherwise>      
</c:choose>
