Syntax error, unrecognized expression for href

Question

When I add below script and run. I am getting this:

Uncaught Error: Syntax error, unrecognized expression: ul li a[href=#!id1]

Answer 1

I tried the solution provided by

https://github.com/jquery/jquery/issues/2885

which worked for me. I search for [href=#] in js and replace with [href*=\\#]

a[href*=\\#]:not([href=\\#])
