Var hideType = 'hide '; // optional parameters include hide, slide, and fade.
Var hideDelay = 0; // The time when the div hiding process is suspended
Var hideTime = 0; // The delay hiding time of the floating div
Var zIndex = 100; // when multiple divs obtain the focus, the div is at the top layer.

A bit of technical points to use when doing a small function are recorded:1. Use the timer in JS:Both of these methods can be used to implement JavaScript after a fixed time period. But each has its own application scenario.MethodIn fact, settimeout and setinterval have the same syntax. They all have two parameters, one is the code string to execute, and one is the time interval in milliseconds, and the code executes after that time period.However, the two functions are still different, setinter
The difference is that setinterval executes the code once every other specified time period, with repeatability. and settimeout only executes once after the call.
The following is a deep understanding of two functions through the establishment of functions and the automatic deletion of letters;
