Requirement description: Data can be added dynamically on the page, such as table, and rows can be added dynamically by clicking the button. Or when the page
is loaded, the table data is obtained from the background through ajax. And now we want to get one of the values, how to get it?

If you want to obtain it through an event such as click, mouseover, etc., you can use the live() method

If it is not through an event, we have to get the value or perform other operations when the page is loaded

live( ) method will not work because we cannot pass in an event.

cannot be obtained at this time. We can observe the problem from the browser:

From the above, it can be seen that the data is not available when the alert is issued. After loading, the console does not print out the information, so the data cannot be obtained at this time.

Use the ajaxComplete() method to run the code to be executed when the request is completed. We modified it as follows:


At this time, The page has already loaded the data when getting it.
