Use the model to bind the content status, click on a certain content in the repeat, and then make a request to the background. After the request is successful, the status value of the content is modified, but the current result is that the content is requested. Nothing wrong, but when the page is rendered, all status values also change. Although the background data only requests one... But on the page... it feels like the same image description is requested 
How to modify this? Please give me some advice
