I found already this, but it concatenate instead of addition...

Can anybody make this script work?

 

<SCRIPT LANGUAGE="JavaScript">

 

function add()

{

 

var position1 =document.getElementById("EditRecordR397_Gegrilde_eend_sappig").value;

 

var position2 = 1

 

 

var allpositions = position1 + position2;

 

document.getElementById("EditRecordR393_Kip_met_Marrokaanse_kruiden").value =allpositions;

 

}

 

document.getElementById("caspioform").onsubmit=add;

</SCRIPT>>

I can add numbers now, but i can not do the 'if then' check..

When Virtual1 is "Y" then add +1 to Fieldxx

 

Thank you if you could help me out..

<SCRIPT LANGUAGE="JavaScript">

 

function add()

{

 

var totalVal = parseInt((document.getElementById("EditRecordR393_Kip_met_Marrokaanse_kruiden").value)) + (+1)

 

document.getElementById("EditRecordR393_Kip_met_Marrokaanse_kruiden").value =totalVal;

 

}

 

 if (document.getElementById("@cbParamVirtual1").value == "Y") {

    document.getElementById("caspioform").onsubmit=add;

 }

 

</SCRIPT>>

Check the line var totalVal = parseInt((document.getElementById("EditRecordR393_Kip_met_Marrokaanse_kruiden").value)) + (+1)

as it is missing a ";".  Also  if (document.getElementById("@cbParamVirtual1").value == "Y"), remove the "@".

 

Have you tried the following:

 

var is_checked = document.getElementByID("cbParamVirtual1").checked;

if(is_checked){

   document.getElementById("caspioform").onsubmit=add;

}

hi GoCubbies,

thank you for the advice.

 

I tested all, but still not add +1 when the checkbox is checked.

The code for adding +1 to another field is working, but it is like the if-then code is not detecting anything?

I am searching this for 2 days already.

Maybe you can see other faults?

 

thanx,

the updated code:

 

<SCRIPT LANGUAGE="JavaScript">

 

function add()

{

 

var totalVal = parseInt((document.getElementById

 

("EditRecordR393_Kip_met_Marrokaanse_kruiden").value;)) + (+1)

 

 

document.getElementById

 

("EditRecordR393_Kip_met_Marrokaanse_kruiden").value; =totalVal;

}

 

function is_checked_and_change()

{

   var is_checked = document.getElementById("cbParamVirtual1").checked;

 

   if (is_checked)

      {

         document.getElementById("caspioform").onsubmit=add;

      }

}

 

</SCRIPT>>

Hello Mel,

 

If I understand correctly, you can use the following code:

<SCRIPT LANGUAGE="JavaScript">
function add()
{
var is_checked = document.getElementById("cbParamVirtual1").checked;
if (is_checked)
 {
   var totalVal = parseInt(document.getElementById("EditRecordR393_Kip_met_Marrokaanse_kruiden").value);
   totalVal = totalVal + 1;
   document.getElementById("EditRecordR393_Kip_met_Marrokaanse_kruiden").value=totalVal;
   }
}
document.getElementById("caspioform").onsubmit=add; 
</SCRIPT>

And it requires set the field R393_Kip_met_Marrokaanse_kruiden as Hidden, select Data Source Fields in the On load assign drop down box, and selet your field in the next drop down box.

 

I hope, it helps.

I tested this with checkbox and radiobuttons, did not work.

 

Only List and dropdown give the info...

 

Finaly i worked with this to add up 1 to the existing amount:

 

<script language="JavaScript">
function concatenate()
{
var position1 = parseInt(document.getElementById("cbParamVirtual1").value);
var position2 = parseInt(document.getElementById("EditRecordR393_Kip_met_Marrokaanse_kruiden").value);
var allpositions = position1 + position2;
document.getElementById("EditRecordR393_Kip_met_Marrokaanse_kruiden").value=allpositions;
}
document.getElementById("caspioform").onsubmit=concatenate;
</SCRIPT>

 

 

many thanx!

Mel

Mel,

 

In terms of the code Jan provided, my understanding is that the virtual field as a checkbox did not function.  Are there other virtual fields present on the page, or is this checkbox the only one. The reason I ask is that the naming of the form element of virtual fields may be the issue.  As a reference, take a look at http://forums.caspio.com/index.php/topic/4377-js-guide-caspio-form-elements/.

 

I was able to test out Jan's code both with a virtual checkbox field and a YES/NO datatype field from table and it worked in a test page that I created.
