Convert javascript var into a java String

Hi all,

I have an iview that receives an event. I tried to work with JSP this time. After I received the event I have a java-script var. I would like to put the content of the var into a htmlb-component:


EPCM.subscribeEvent( 'urn:com.test.EPCFExample', 'Event', getEvent);

function getEvent( evt ) {

var nameEvent = EPCM.loadClientData('urn:com.test.EPCFExample','textInput');



I have completly no clue what to do with the variable. Can this be transferred into a java-String? If I use it as value-parameter for an InputField it will be interpreted as a String ;-(








Thanks for any help!

    Hi Martina,

    to access HTMLB elements as JS HTMLB objects, the following function you should always wear in your pocket:

    function getHtmlbElement(pElementId) {
      var loDocForms = document.forms;
      for (var j = 0; j < loDocForms.length; j++) {
        try {
          var funcName = loDocForms[j].id + "_getHtmlbElementId";
          func = window[funcName]; 
          var element = eval(func(pElementId));
          if (element != null) {
            return element;
        } catch(ex) {

    Setting "nameEvent" into the HTMLB tag cannot work because this is calculated at server side (it's JSP - Java).

    With the method given above, you retrieve the HTMLB JS object, here the HTMLB JS object InputField, when you write (and have set JSObjectNeeded to true):

    var myInpField = getHtmlbElement('eventField')

    On this object, you can set a value by


    I didn't test it (the last combination), but it should work.

    A general question is if it is really needed to pass the data via ClientDataBag. Why not passing as a value of the event?

    Hope it helps
