jsonp() Error: Timeout at index.js:63 undefined #59

fn：
(error, data)=>{
console.log('jsonp()', error, data)
}

when I use jsonp( url, {}, fn) , I find status is 200 in network and &callback__jp0 is attached to the url.

but response is json in firefox

and no response in chrome

I know the true response is __jp0&&__jp0( ... )
but I don't know how to make it

this is my whole code(actually I have used {} or {timeout:"10000"}
