Double alert onChange field

Posted on by Pocia

Hello,

I've got the following javascript function called onChange event on the field:

function message() {
return alert("message");

}

The alert is shown correctly, while changing the field value, but also for the second time while saving the record. There is no onSave form script, as there are no more scripts on the form.

Appreciate your help on the matter.

RE: Double alert onChange field

Hi,

If you haven't registered your method on save and if there is not other script on save which is changing the value of that field then you should not get the alert on save.

can you share your script and some screenshot? It is possible that the onchange is getting triggered from some script.

Do you get the alert if you just update/save the record (o.e. without changing the field)?

Hope this helps.

Hi Pocia,

This one is common if you have plugin that will change the property. So after on save, CRM will refresh the value and then trigger on change event. Please do check weather you have logic to change this property or not.

Sure,

Note, that there's only one script (mine) on the form. Field is named Description

For onSave:

For onChange:

Script (this is literally whole script :) )

And regarding your last question: alert shows only when changing the field, and while saving the record after changing the field. When changing other fields, alert doesn't show.

Hi,

Can you remove the return keyword and try i.e.

function disclaimer_text()

{

alert("hello");

}

Hi Pocia,

am sorry but which error you are talking about. You mentioned the issue is that the message appears twice. Are you saying you now getting an error?

Hi Pocia,

Can you check inside plugin whether this field value is set again (even though still same value)?

Search field name in plugin code, or test by disabling plugin steps related to this entity to locate the one causing problem.

Regards,

Abby

RE: Double alert onChange field

I had exactly this scenario recently. I proved to myself that the OnChange event was firing again after the record was saved but I think only for new records.

I did not conclusively prove whether this is by design or an error. But, this link https://msdn.microsoft.com/en-gb/library/gg334481.aspx#BKMK_FieldOnChangeEvent says:

"This event also occurs when data changes on the server are retrieved to update a field when the form is refreshed, such as after a record is saved."

I wonder if that is causing the script to run again.

Hi Pocia,

Go to form form designer -> form properties -> you can get onload and onsave event there in the event section.

Hope this helps.

RE: Double alert onChange field

After playing around with script for a while, it's the latest version. Basically, it checks, whether there were performed changes to the field, and if field isn't empty show message:

function disclaimer_text() {

var dirty=Xrm.Page.getAttribute('description').getIsDirty();

var value =Xrm.Page.getAttribute('description').getValue();

if(dirty==1 && value != null){

message();

}

}

function message(){

alert("msg");

}

However, there still is the double alert problem. When I'm filling the field with one line text, alert is shown once (onchange field event):

But when I'm adding multiline text to the field, the alert is shown two times: onchange field event and onsave form event:

Strange, isn't it? I honestly have no idea now what is going on :)
