    JavaScript Error The content of elements must consist of well-formed character data or markup.

    valatharv
      Hi,

      I am trying to implement dependent dropdown in Seam using an example.

      but I get the error as "content of elements must consist of well-formed character data or markup."

      The same code works perfectly fine when I use Simple JSP project.

      The error is on the for loop line....
      for (o=1; o < age.length; o++) //HERE is the error...
         {
           agelmt[o].text = age[o];
         }

      Please suggest.
      ...

          Need more info. Post code for xhtml, and bean. The error suggest some kind of dirty output.

            Thanks for looking into it.. I am using hardcoded values.... no bean.
            When I run the same code using simple JSP it works perfectly fine.

            Scenario : I have 2 dropdowns, value in 2nd is dependent on 1st dropdown.
            I am using .txt file to read the values
            1st dropdown contains : ItemA, ItemB, ItemC
            2nd dropdown displays 1,2,3 when user selects ItemA.
            2nd dropdown displays 4,5,6,7 when user selects ItemB, similarly 8,9 for ItemC selection.
            I got the example while searching...

            ItemA.txt contains 1|2|3, ItemB.txt |4|5|6|7 and ItemC.txt |8|9.

            This is the xhtml I am using in Seam, it gives error on line
            "for (o=1; o < itemDetailsar.length; o++)", (The content of elements must consist of well-formed character data or markup)

            Please suggest what is wrong....

            Complete Test.xhtml

            • 3. Re: JavaScript Error The content of elements must consist of well-formed character data or markup.

              I cannot really say why it doesn't work, but jsf modifies stuff quite a lot. I suggest you step through your javascript in firebug or equivalent.


              Is there a particular reason why you try to do this with javascript? I think it would be a lot easier (even trivial) to do this with ajax4jsf.

                Thanks for replying Daniel...


                No there is no reason for using javascript, infact I would definitely prefer ajax4jsf, I tried searching for samples but couldn't found any....


                I really don't want to use javascript or simple JSF, ajax would be best choice...


                Please let me know if you can suggest any sample ajax4jsf, this is very urgent for us.

                  I tried ajax4jsf, the code works fine if I create separate test.xhtml and use only these 2 dropdowns..
                  But, when I try to embed in our main xhtml (which have multiple panels), looks like <a:support event="onchange".. is not fired. Both files uses the same war...

                  StudyEdit.xhtml behavior:
                  I can see Master and details dropdown, 1st. dropdown displays List as "Item A, Item B, Item C", 2nd. dropdown displays only A,B,C.
                  If I change any 1st. dropdown, 2nd. dropdown does not change.
                  Same code works fine if I create separate test.xhtml and use only these 2 dropdowns..

                  Please suggest what is missing ...here are both xhtmls

                  Test.xhtml (this works fine)

                    Talvez un poco tarde para la respuesta, pero en fin a muchos puede servir, me pasaba lo mismo pero la solucion es la siguiente:

                    <script type="text/javascript" language="javascript">
                      <![CDATA[
                      //]]>
                    </script>


                    De esa forma reconoce los caracteres directamen sin tenerlos que hacer un parser.

                      Muchas Gracias:

                       

                      Me tomo estos momentos para agradecer esta sencilla nota que me saco de apuros. Me gustaria agregar esta nota:

                       

                       

                      <script type="text/javascript" language="javascript">

                        <![CDATA[

                      Código del Script...

                        //]]>

                      </script>

                       

                      Saludos.
