Submitting an ATG Form Using a Text Link

It  has always bedeviled me how to submit an ATG form using a text link. I have asked many people about this but no one seems to know. Finally with the help of ATG support I figured it out.
Below is a simple example of how to do it. The trick is the hidden submit input which triggers ATG to call the handleSubmit method of the form handler.

<%@ taglib uri="/dspTaglib" prefix="dsp"%>


<dsp:page>


<script>
  function submit(form) {
    form.submit();
  }
</script>


<dsp:form action="<%=request.getRequestURI()%>" method="post" name="testForm">


  Foo: <dsp:input type="text" bean="TestFormHandler.foo"/>


  <p><a href="javascript:submit(document.testForm)">Submit</a>


  <dsp:input type="hidden" bean="TestFormHandler.submit" value="Submit"/>


</dsp:form>


</dsp:page>
