Unable to Call JavaScript from Custom Button on Ribbon Workbench

Posted on by Tanmay D365

Hi,

In my Dynamics environment, I have created a custom entity 'Car', that has two custom form fields:

Cost in Source Currency
Cost in Target Currency.

I have also created a custom button, in Ribbon Workbench, on the Car entity, which calculates the amount in the target currency, when the source currency is taken as an input.

Note: I have installed Ribbon Workbench directly on Dynamics 365 interface, not XrmToolBox.

For this, here is the sequence of steps that I've used:

The custom button is clicked on.
A JavaScript should be called that calculates accepts the source currency, and calculates the target currency.
The target currency should be displayed on the form of the Car entity.

I have followed the exact same steps as per the documentation available. Which means:

The custom button is linked to the command, which in turn calls an action.

Within the action, my web resource is registered. The primary control is passed as the execution context.

But while attempting the above, I came across the following problem:

On click of the ribbon button, my JavaScript is not getting called. Nothing is happening. I am neither getting an error, nor the desired output.

Is there any reason behind this? Because when I tried registering another JavaScript on the account entity form, the script is successfully being called, on button click.

Therefore, I had a doubt whether my script is correct. It turns out, when I register my script using 'OnSave' event, the script runs perfectly with the correct output.

Here are the screenshots:

ACCOUNT ALERT button works perfectly

FIND INR COST button unable to call JS file

Has anyone come across a similar issue while using Ribbon Workbench?

If I follow the same steps on XrmToolBox instead, will it make a difference?

Would be really helpful if anyone could suggest a solution.

Thanks and Best Regards,

Tanmay

For any future Ribbon Button I would suggest start using new Power App functionality

learn.microsoft.com/.../use-command-designer

OOB and I found it very easy to use. You can use either FX or JScript.

The only downside is that for current release, you can only add new Button and not remove the OOB buttons.

Hi,

Yes we don't need getFormContext when you pass Primary Control as parameter from ribbon but you do need when you attach your javascript function on onload/onchange.

RE: Unable to Call JavaScript from Custom Button on Ribbon Workbench

Hi,

Thank you so much for your help!

I've made the necessary changes in my JS code, as suggested, and now it runs perfectly, on button click.

Would be really helpful to know why the syntax works.

Any reason why the getFormContext() method should be removed, when ribbon button is the trigger?

But in the case where JS is invoked either OnSave/OnLoad/OnChange, I have to add getFormContext().

Thanks!

Best Regards,

Tanmay

Hi,

Replace below line of code

Var formContext=executionContext.getFormContext();

With

Var formContext=executionContext;

Here is the JS code:

var CalculateTotalCostInr =

{

SetTotalCostInr: function(executionContext)

{

debugger;

"use-strict";

var formContext = executionContext.getFormContext();

var totalCostUsd = formContext.getAttribute("tanm_totalcostusd").getValue();

var exchangeRate = 82.26;

var totalCostInr = totalCostUsd * exchangeRate;

formContext.getAttribute("tanm_totalcostinr").setValue();

alert(totalCostUsd);

}

}

Seems likes there isn't an issue with the syntax, since my script works when I add it on OnSave event. The only time when it doesn't run, is when I try to call it via the ribbon button.

I'll try removing and then re-adding the button, as suggested.

Best Regards,

Tanmay

Hi,

Can you please add debugger in your code.

Add alert in your code at the very first line.

Try to Delete Action from command and recreate again

I hope you don't have any syntax error in your code.

Please share your js code
