Summary by CodeRabbit

• Bug Fixes
  • Fixed an issue where AJAX requests with cross-domain origins were incorrectly processing script-type responses through the data converter pipeline, which could lead to unexpected behavior. The application now correctly skips converter processing for script data types in cross-domain scenarios.

📝 Walkthrough

Walkthrough

A guard clause is added to the ajaxConvert function to skip processing script-type responses when handling cross-domain requests, preventing unwanted converter execution in that scenario.

Changes

Cohort / File(s)	Summary
Cross-domain Script Response Guard front/lib/datatables/datatables.js	Adds conditional check to skip script-type converter processing when request is cross-domain, altering control flow within the converter loop.

Poem

🐰 Cross-domain scripts I'll skip with glee,
A guard clause hops between safety and spree,
No scripts shall pass when domains don't align,
This rabbit ensures conversions align just fine! 🛡️
