    Hi

    To check the value of a checkbox, you use the the following javascript

    if(document.getElementById("<id of the checkbox>").checked == true)

    If this doesn't work, it may be because you are using HTMLb and you will have to generate the ID field dynamically so that you capture the correct ID of the checkbox

    I hope this helps

      Hi

      I think the problem is that when you use the getParamIdForComponent you need to pass in the relevant component as opposed to the name of the component in quotes

      Try this code in your JSP page

      <%String checkBoxId = null;%>

      <hbj:checkbox

      id="myCheckbox"

      text="Click Here"

      tooltip="Click Here"

      disabled="false"

      checked="false"

      >

      <%checkBoxId = myContext.getParamIdForComponent(myCheckbox);%>

      </hbj:checkbox>

      Where myContext is the ID of the hbj:content.

      The javascript would be

      document.getElementById('<%=checkBoxId%>').checked;

      I hope this helps
