Detailed explanation of the steps to dynamically generate Table using JQuery+Ajax
This time I will bring you JQuery A detailed explanation of the steps to dynamically generate a Table with Ajax. What are the precautions for JQuery Ajax to dynamically generate a Table? The following is a practical case, let’s take a look.
Foreword:
The approximate function of this example is to call the general handler (Handler) through JQuery's Ajax at the front end to obtain the information that table needs to be displayed , and then convert it into json format and return it to the front desk. After the front desk obtains the data, it loops to build the rows of the table. It is best to append the rows to the table.
Objectives:
a Be familiar with the use of simple JQuery Ajax
b Understand how to construct basic Json format data (Json can also be constructed through Third party dll)
c Get familiar with the basic usage of handler
1 Simple rendering
2 Front desk code
