I want to take the dialogs from my main html file and put them into their own files that link to the main html file. I saw that iframes and JQuery are unsupported, https://developer.adobe.com/photoshop/uxp/guides/uxp_guide/unsupported/, so I’m not sure how to go about it. Any guidance is appreciated!
Here you go - ignore the mention of WebViews
Some people are using React and its components to achieve something similar. It is much better than JQuery but it also requires learning much more than just injecting some HTML in some DIV. But it is worth it if you plan to develop a lot of plugins or just one very complicated one.
I use Vue and am still making sense of getting it running properly under UXP!
