Problem Description
The page uses the upload image, I use the input file, but when I select an image and click the input again to select an image, there is no response
- I checked online and said that the value of the input needs to be cleared, and the change event will be triggered next time.
I tried ===> to no avail - Said to replace the original input element and re-render the input element,
I tried ===> to no avail - Say, put the input into a form, and when the input change event is called back,
I tried to reset the form ===> to no avail - In the end, when I was in despair, I saw a glimmer of light. A netizen said that the change event was not bound.
I tried it ===> Ah ha ha ha ha ha ha, bingo
Summary: replace the input element, re-render, and then bind the change event function
