Timer:
It is used to execute a program after a specific period of time.
Regular execution in JS, difference between setTimeout and setInterval, and l release method
SetTimeout (Expression, DelayTime): After DelayTime, an Expression is executed. setTimeout is used for a delay period before a certain operation.
SetTimeout ("function", time) sets a timeout object
SetInterval (expression, delayTime). Expression is executed for each DelayTime. It is often used to refresh an expression.
SetInterval ("function", time) sets a timeout object
SetInterval indicates automatic repetition, and setTimeout does not.
ClearTimeout (object) clears the set setTimeout object
ClearInterval (object) clears the set setInterval object
The Code is as follows:
SetTimeout (aa (), 1000) // unit: milliseconds
Function aa ()
{
Location. href ('address ');
}
