[HTML/HTML5] The HTML SELECT control setting disabled cannot pass a value to the background

Finally, the background receives the foreground parameters, and the shape value stored in the database is always 0.

The program also did not throw an exception, and then checked the network request and found that when the foreground post was submitted, there was no value of the shape submitted at all

found that it could not be submitted normally, I set the tab to read-only, is it a problem of read-only, I found that disabled was removed,

The front end can pass the shape parameter value to the background, which is indeed a disabled problem




Solution:

In order not to affect the aesthetics, I set the read-only property of select and added a hidden input form field

Then, set the value of the hidden form field with jQuery and submit.
