Jquery's ajaxSubmit () asynchronously uploads images and saves form data. Demo code _ jquery

Use jquery's ajaxSubmit () to asynchronously upload images to save form data. The Demo code is as follows. If you are interested, refer to the following code and hope to help you (jsp needs to be introduced: jquery-1.9.0.js, jquery. form. js), jsp pages are produced by bootstrap, and you don't need to worry about the labels you don't understand. form forms are similar. The code is simple, just to demonstrate how to use ajaxSubmit to asynchronously upload images and save data. Please include it!
