Adding attributes to form elements

I'm currently using the drop down selection box provided in ChronoForms. Because of some javascript I'm adding, the select element needs to look like this:

<select onchange="Disable(this,'add','delete');" >

Is there a way to add this onchange attribute using the current drop down box, or do I need to delete the drop down box and add the box using the custom html element?

Hi chriso0258 ,

Please try this in a Load JS action instead:

window.addEvent('domready', function() {
  $('select_id').addEvent('change', Disable(this, 'add', 'delete'));
});

You need to add the select id and 'this' may need to be changed.

I've added your code and the Add/Delete Members button are diabled. However, they remain disabled on any option. I probably don't have a correct variable in place.

The id for the selection box is:

<select id="membership" class=" validate['required']" name="membership" title="" size="1">

The id for the Add/Remove Members and adding rows custom html code is 'personal_info'. The custom code for the Add/Delete Members button is:

<INPUT name="add" disabled="disabled" type="button" value="Add Member" onclick="addRow('dataTable')" />

<INPUT name="delete" disabled="disabled" type="button" value="Delete Member" onclick="deleteRow('dataTable')" />

And the JS code in the Load JS action I'm using including your code is:

window.addEvent('domready', function() {
  $('membership').addEvent('change', Disable(this, 'add', 'delete'));
});

function Disable(s,d1,d2){
 var frm=s.form;
 frm[d1].disabled='disabled';
 frm[d2].disabled='disabled';
 if (s.value&&s.value>10){
  frm[d1].removeAttribute('disabled');
  frm[d2].removeAttribute('disabled');
 }
}

I have not included the JS code for adding the rows since that part is working, however it is in the Load JS action as well.

Hi chris0258,

I'm not sure I follow your code but try using
frm[d1].setProperty('disabled', true); and frm[d1].setProperty('disabled', false);

Personally I'd add ids to the inputs and then use $(d1) to identify them.
