Dynamics 365 For Customer Engagement: Supported Browser & Document Object Model Considerations

Dynamics 365 for Customer Engagement supports multiple web browsers including Internet Explorer, Microsoft Edge, Mozilla Firefox, Google Chrome, and Safari. When developing JavaScript and other customisations for Dynamics 365 for Customer Engagement, it is important to ensure that the customisations work well in all supported browsers, and account for differences in browsers when it comes to Document Object Model (DOM) manipulation of HTML and XML.

Most JavaScript developers regularly interact with DOM elements in code, but DOM manipulation for accessing elements from application pages and entity forms in Dynamics 365 for Customer Engagement is completely unsupported. The Dynamics 365 development team have reserved the right to change the composure of pages, including the ID values of elements. The Client API object model is the correct way to access these elements as it protects your code from changes in page implementation. As long as you develop supported customisations, you will be able to maintain consistency in Dynamics 365 for Customer Engagement across all supported web browsers.
