Issue calling onchange javascript function

Tonito99Feb 12 2014

Hello,

I'm working on apex page (master detail page).

The requirement is to calculate total amount from tabular form and set it to total field on master region.

And then total field should be calculated with profit field from master region.

I setup a javascript function which does calculation from tabular region and set total field on master region.

Issue is that grand total of master region is not calculated, even for calculation of grand total I setup another function which is called onchange of tabular form total.

onchange="CreditAmountTotal(), SellingPrice();"

CreditAmountTotal()      -- Is working as expected

SellingPrice()                -- Not doing calculation called from tabular region, it's working when is called from items on master region

grand total = total + profit

function CreditAmountTotal()

{

  var items = document.getElementsByName("f07"); // Tabular form column to add up

 

  $total = 0;

  $itemValue = 0;

  for (var i = 0; i < items.length; i++)

  { 

   // if non-numeric character was entered, it will be considered as 0,

   // isNaN returns true if anything but number was entered

   if(isNaN(items[i].value) || items[i].value == null || items[i].value == "")

    $itemValue = 0;

   else

    $itemValue = parseFloat(items[i].value); // convert to number

  

   $total =$total+ $itemValue; // add up

  }

 

  // $x sets the text field to be updated to the column total just calculated

  $x('P20_AMOUNT').value = $total;

}

  function SellingPrice(){

    function getVal(item){

   if(document.getElementById(item).value != "")

     return parseFloat(document.getElementById(item).value);

   else

     return 0;

    }

    document.getElementById('P20_SELLING_PRICE').value =

  getVal('P20_AMOUNT') + getVal('P20_TOTAL_PROFIT_AMOUNT') + getVal('P20_PARTICIPATION_AMOUNT');

  }

I agree with your hunch. The parser should treat dlmd:record as just another element (colons are allowed in XML element names when namspace feature is turned off). Maybe you could elaborate a bit on what parser you're using, what Document (JDOM or DOM) you're building and where the exception comes from (io exception is kind of strange, too).

Hi
I am using JAXP 1.1 and I am builidng a DOM document. The exception I get is a SAX Exception and the following is the stack trace

java.lang.NullPointerException
at org.apache.crimson.parser.Parser2.parseInternal(Parser2.java:523)
at org.apache.crimson.parser.Parser2.parse(Parser2.java:304)
at org.apache.crimson.parser.XMLReaderImpl.parse(XMLReaderImpl.java:433)
at org.apache.crimson.jaxp.DocumentBuilderImpl.parse(DocumentBuilderImpl.java:179)

at javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:161)

at dlnet.DLXMLParse.dlStart_Parse(DLXMLParse.java:50)
at dlnet.DLTrigger.main(DLTrigger.java:40)

Hope you can suggest a solution.....

I see. I only tried xerces with your example and it was just fine. You're using Crimson, though and there seems to be a bug in crimson1.1. Go, get crimson1.1.1 from http://xml.apache.org and it'll parse fine.

Good luck,
Leo.

Using the new version of Crimson does not help either. After I build the new Document Factory I set the namespace awareness to false and yet it gives me a sax exception......Could something else be wrong too!??

Thanks for your help....

Prashanth,
this is what I'm doing. First, the parser test code:
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;

public class JAXPDOMTest {

    public void domParse(String url) {
        DocumentBuilder parser;
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setValidating(false);
        factory.setNamespaceAware(false);

        try {
            parser = factory.newDocumentBuilder();
            Document doc = parser.parse(url);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    static public void main(String[] args)
    {
       JAXPDOMTest x=new JAXPDOMTest();
       x.domParse("test.xml");
    }
}
and here's test.xml:
<?xml version="1.0"?>

<metadata>
   <schema>Schema 1</schema>
   <schemaversion>DX:MD1.0 S:1.0</schemaversion>
   <dlmd:record>Record</dlmd:record>
</metadata>
jaxp-1.1 is my directory containing the official 1.1 release and my complete classpath look like this:
CLASSPATH=d:\xml_tools\jaxp-1.1\crimson.jar;d:\xml_tools\jaxp-1.1\jaxp.jar;.

I run the above (java JAXPDOMTest), I get:
java.lang.NullPointerException
at org.apache.crimson.parser.Parser2.parseInternal(Parser2.java:523)
at org.apache.crimson.parser.Parser2.parse(Parser2.java:304)
at org.apache.crimson.parser.XMLReaderImpl.parse(XMLReaderImpl.java:433)

at org.apache.crimson.jaxp.DocumentBuilderImpl.parse(DocumentBuilderImpl.java:179)
at javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:134)
at JAXPDOMTest.domParse(JAXPDOMTest.java:15)
at JAXPDOMTest.main(JAXPDOMTest.java:24)

I set the class path to:
CLASSPATH=d:\xml_tools\crimson-1.1.1\crimson.jar;d:\xml_tools\crimson-1.1.1\jaxp.jar;.

and, voila, no exception.

Hope that helps,
Leo.

Hi

This is what I did just now....I created a file out of the pseudo string and passed it to be parsed with crimson.....it gives me an error irrespective of whether I turn Namespace awareness true or not!

What could the reason be?

Thanks
Prashanth

Well, that seems to be classic dilemma. The same code works fine on my machine, but has trouble on yours. I'm running on 95 with JSDK 1.3 (build 1.3.0-C).
I'm afraid I can't help you any further, since I can't reproduce this behaviour.

Leo.
843834
Thanks anyways....guess I have to figure it out myself.
Prashanth
843834
It finally worked!!!! This is what I did. I had to delete the jar files in the \lib\ext directory of Java Runtime Environment and it started working. Thanks Leo you have been of great help.......

Prashanth
843834
Yeah, that's a valuable lesson. jar files in lib/ext, I believe, are accessed before stuff in the class path. Glad to hear it's working.

P.S.

Yup! I did....It would be helpful if yo could throw some light one one other question i've posted!

Thanks
843834
Thx for the DDs. I saw this question before, but haven't done anything like this and I'm afraid, I can't give you advice on that one, but my instincts tell me, you'd be better off with the database solution.

Good luck.
843834
Thanks for the info.
I had the same problem, I have it no more

Small note: I had to put the XALAN.jar file AFTER the crimson.jar and jaxp.jar in order to make it work.
