Asynchronously uploads an array from foreground input to the background and into the database First look at the picture:Using AJAX asynchronous interaction data, not in the form of a JSON array to the background, but the use of a character array to upload it into the background. Dynamically add each row of data, the corresponding data in each column into an array, and upload to the background for storage.
