A simple solution to how to control the AJAX read data of a page read only once!

For example: A page has a button, click the time with Ajax to get the data in the background, to obtain a successful return. Don't get the data the next time you click.

There are many ways to solve this problem:

1. Use the Get method to read the data and cache it.

2. Use the jquery data method to manually cache and read the data to determine if the cache exists.

My solution is to give the button a flag when the button loads it does not go backstage to get the properties of the data (such as Readnot).

Then use Removeattr ("Readnot") to remove this property after the first time you have gone to the background to get the data successfully.

This will only determine if the Readnot attribute is present each time the button is clicked.
