I have created a content type 'Property', has fields 'Property name','Address line1','Address line2','Address line3'.
I don't want to add duplicate properties in database, so that I want an AJAX call while filling above fields and check is there any property available in database or not with current provided values of fields.
If there is any one result, I want to show it on modal.
The only problem is, Where should I write an AJAX code?, And where will the business logic ?.
Is there any way to do this?. kindly suggest me. thank you.
