Question

As I’m not a javascript nor a jsf expert, I ask if it is possible to define a global variable and then pass it as a parameter for an action-bound method.
Maybe it is more clear with an example… 🙂

In my xhtml code should be something like this:

...
<script type="text/javascript">
  var isEdit = "false";

  //<![CDATA[ 
    function editSelected(selBox, inputFiled)
    {
      var htmlstring = selBox.options[selBox.selectedIndex].text;
      inputFiled.value = htmlstring;
      isEdit = "true";
    }
  //]]>
</script>

...

<h:commandLink
  styleClass="waiButton"
  value="#{lakshmiMsg.commonButtonAdd}"
  action="#{detailController.addCreator(**isEdit**)}"
  rendered="#{detailModel.mode != detailModel.viewMode}">
</h:commandLink>
...

Would be something like this possible?
If not, are there maybe other ways?

Answer 1

You could alter a hidden input field by JS. E.g.

<h:inputHidden id="edit" value="#{bean.edit}" />

with

document.getElementById("form:edit").value = isEdit;

An alternative is to just don’t do the editSelected() job in JS, but instead do the job in pure JSF with <f:ajax> magic. As the functional requirements for this are not clear because the code is incomplete and not self-documenting enough, I can’t give a kickoff example for that.
