You can add custom parameters and variables required during the increase or decrease process, such as $ ("table"). dynamicaddremover ({param1: "param1", param2: "param2 "});
For example, options. param1.
. The root container must have a unique id and must be unique at the specified time. If multiple modules (multiple root containers) need to be used: $ ("# table1 "). dynamicaddremover (), $ ("# table2 "). dynamicaddremover () and so on.
The id and name in the newly added control are not updated. If you have special business needs, add the business logic for generating the new id in addedevent.
