This article mainly introduces how to implement automatic page Jump in JavaScript after 5 seconds. It involves the use of javascript recursive call and timer function setTimeout, which is of great practical value, if you need it, you can refer to the code that automatically jumps to the JavaScript control page 5

initialize most of the members of a timer_list. However, the timeout function is required for our own setup, which is function. 3. Register the timer with the Add_timer function. 4.mod_timer Restart the timer. Note that the timer is not circular, and the Mod_timer function needs to be called repeatedly.The following is an example:NKEY.C:#include #include #includ
