I include the jquery.js and some other js files in the index.html, but they only work when the app at the starting root page. If i switch to other pages the js are not working any more.
Is there somebody comes across this issue?

jQuery isn’t performant with Angular. So even if you get this working, you might want to rethink your strategy.

Its works on root page perfectly. If the same page set as second page it not works.

Don’t do it. Dead end idea.

Work with your framework of choice instead of trying to circumvent it.

Help me ,can i reload all JavaScript linked in the index.html in the other page
