Run Clientscript one time only

Elias11 · ‎07-03-2014

Hi Experts

I am trying to create a client script that has to run only on time in every Record.

e.g. I have 2 fields, Field A and Field B , both are a reference type to the table users.

The Client script I have created is OnChange which if the Field A has changes or Loaded the Manager of the user of the field A will be set in the Field B.

So far so good. it works.,

Now as soon the manager in Field B is set for the first time I do not want anymore that the Field B changed.

the clientscript must not run till a new record is created.

Anyone an idea?

Thanks

Elias

I GOT IT

My Idea was correct but I wrote it wrong

I did ask if the value is Empty then run the script and if not return;

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

var FieldB = g_form.getValue('u_fieldB');

if(FieldB== '') {
var fieldA= g_form.getReference('u_fieldA');
if (fieldA.manager != '')
g_form.setValue('u_fieldB' , fieldA.manager);
} else {
return;
}
}

Thank you

Elias

Hi Elias,

You can use "isNewRecord"

Please refer section 13.6 in the below wiki link for further details

Once the Field B value has set and make it as readOnly. Don't give access to anyone to change the Field B as set at the first time.

Well Anish

the problem is that the client script that is running will change it again everytime the form will load or the Field A will change.

Thanks
