Hi @zhangjian8652 thank you for reporting this.
I've never experienced anything similar, are the requests to the backend failing? Is there a URL I can take a look at for this?
Thanks!
it looks like this image.
I think it may be caused by the async of ajax.
when images in session have been changed.
I understand, and without seeing how it's being called, I can't spot where the issue is, because if there's only 1 request to start the session, it should work fine. Can you show me where and how the code is working?
That's right.
I click the refresh button twice very fast, first time is considered as A, second time is considered as B.
A get the verify json data in session ,and then B get the json data , too. json data of B is the latest.
after the two actions , js start to render the html document. There's a posibility that B is run before A,
A render the document override B.after this action, browser start to load images in the session. So the tip message is A, but images in the session is B. This caused there's no answer.
Thanks for the explanation.
It seems to me, from what you're saying, that the first request to the new images might be taking longer than the second one sometimes, making it so that the images you're seeing are for the first refresh and not the second.
There are a few ways to make that possible to prevent, but I honestly think it's an overkill for the goal here.
You could prevent any requests from happening while there are still unfinished requests, or simply make them synchronous. Whatever suits you better there.
Does that make sense? Do you need any help with how you might do that? If so, what front-end version are you using? jQuery?
yes, i used jQuery. I understand what you said. Thanks for your help.
Alright. I'll close this issue now and you can feel free to still ask questions here and even post your solution. Thanks!
If i click the refresh button too fast , There will be no answer image here. Can u help me to fixed it or tell me how to handdle it if i have something wrong.
