Question

I have a spring application where i validate all validations in custom spring validator class.

My form has nearly 15 fields.If there is a error in the last field , how to set the focus to that element.

Does spring tags support that. Any technical ideas ? Currently i display my error messages near the fields itself.

Answer 1

It is possible to use spring:bind tag to determine whether a field or the whole model object has error and the overall status of the object after processing (submission).

<spring:bind path="user.username">
    <input id="inputId" type="text" name="${status.expression}" value="${status.value}"/>
    <c:if test="${status.error}">
        <c:forEach items="${status.errorMessages}" var"error">
            <span class="field-error">${error}</span>
        </c:forEach>
        <script type="text/javascript">
            document.getElementById('inputId').focus();
        </script>
    </c:if>
</spring:bind>

Note:

• The status variable is exposed by the spring:bind tag.
• The javascript part will focus the element when the specific field
  has validation errors.
