Abort pending request to server? about safe-jsonp HOT 7 CLOSED

Hello! Unfortunately, there are no JSONP libraries that could completely interrupt the pending request. Since each JSONP library uses a script element as a transport wich does not support any abort or timeout methods, there is no practical way to cancel a request at the http level. This is a well-known limitation of the browser DOM. You can read more about this issue here:

• https://maxchadwick.xyz/blog/script-tag-timeout-attribute

So, if possible, you should use ajax (xmlhttprequest / fetch) instead with Access-Control-Allow-Origin: * header from server side, because this technology fully supports the abort method at all levels.

Hello! I was afraid that this might be the case but couldn't really find the information I needed. for now I am limited to JSONP unfortunately... Anyway, thank you very much for clearing that up and explaining it in detail :)

I have made some research & testing so it seems i have found some experimental solution wich is made possible by the availability of a sandbox mode in my package, classic JSONP packages can't provide this. So, I have updated the package to 0.5.0 and added ability to abort related http request. This feature will work only when:

• "abortable" option is set
• sandbox mode is activated and supported by a browser (except all IE, I hope you don't need them)
  
  Have fun :)

Hmm... Sadly, but it doesn't work perfectly :) It seems Edge browser has some bug and this solution doesn't work completely with it. I'm looking for some aditional hack to fix this bug for microsoft's freaky child, but currently i have not 100% working solution...

Ah I see. I'm fortunate that I don't have to rely on Microsoft's stupid browsers for my project...
