ajax调用异步问题

Question

i just have a problem with the async mode. in my ajax call i create a pdf, which takes a while (10 - 45 seconds) and in the success section of ajax i call window.open('path of pdf') to show the created pdf.

my issues:

1. When i call the ajax in the sync mode, the function dies in Safari and no popup appears. due to, the request tooks too long...

2. When i call it in the async mode, everything is fine but the popup blocker blocks the pdf. in the sync mode the popup appears, though the popup blocker is active.

Answer 1

Check status with setInterval method every few second.

• if status is creating show preloader
• if status is rejected show message about error
• if status is created redirect to page that you want

What kind of popup blockers can block popups created by JS/HTML?
