| Window setInterval Method |
Window setInterval Method
The setInterval() method calls a function or evaluates an expression at specified intervals (in milliseconds).
setInterval(function(){ alert("Hello"); }, 3000);
The setInterval() method will continue calling the function until clearInterval() is called, or the window is closed.
The setInterval() method can pass additional parameters to the function, as shown in the example below.
setInterval(function, milliseconds, parameter1, parameter2, parameter3);
The ID value returned by setInterval() is used as the parameter for the clearInterval() method.
Tips:
- 1000 ms = 1 second.
- To execute a function only once, after a specified number of milliseconds, use the
setTimeout()method.
