var s = document.createElement('script')
s.src = 'data:,console.log(1)'

document.body.appendChild(s)
// output 1

but if insert this script by jQuery: $('body').append(s), it will be get an error.

this is due to jQuery execute script by ajax of script[src],
and jQuery will append extra query params _=xxxx to prevent script cache by default.

fix this is simple, just set cache=true… may i pull a PR for this?

by the way, anyone knows why jQuery set async=false for inserted scripts?
this is inconsistent with browser's default behavior
