Check existence of any receipt item related to the order

Question

Here is a question. Every order has some receipt item and it has 1(order) to N(receipt item) relation with receipt item. I wanna check that if there is any record in receipt item of order entity or not. How can it be possible? I do like this happen in onload of the order and via JS, not workflow or something like that. I wanna set a button to Enable/Disable if there is any receipt item, so I need onload JS. Is it possible? If yes how? Any help or link? or sample?

Note that I have installed CRM 2011 on-permise.

Use the REST endpoint to get the data in javascript. There is plenty of exemple on the web. https://learn.microsoft.com/en-us/previous-versions/dynamics-crm2011/developers-guide/gg334279(v=crm.5)

Your query shoud look like this: [Your Organization Root URL]/xrmservices/2011/organizationdata.svc/salesorderdetails/?$select=[Put the columns you want]&$filter=orderid eq (guid'" + orderId + "')
