Weixinjsbridge is not defined Android model error +ajax status of 0 resolution process

Recently in the company's projects to monitor, in fact, add the onerror and the like to find a lot of Android models reported this error

Referenceerror:weixinjsbridge isn't defined\n at    <anonymous>:1:12

But the test environment how to measure can not reproduce, many people say because the payment is not properly loaded, but do not try to come out, the problem probably can guess Yes Jsbridge not properly injected

So I dot a little bit of *100, and finally found that the back of the Android button caused, if said just into this page, the page did not load immediately after the exit, will report the above error ...

Found that sure is a lot of Android like Crazy Press back AH.

Ajax Error State 0

In fact, the same as above, but this problem iOS and Android will appear when the page is not loaded (that is, the interface is being tuned), point back, the Send method is not called, will report error status 0 error
