How does jquery stop settimeout?

The clearTimeout () method cancels the timing operation set by the setTimeout () method.

Cancel the timeout set by the setTimeout () method

The argument to the clearTimeout () method must be the ID value returned by setTimeout ().

Note: to use the clearTimeout () method, use global variables when creating and performing scheduled operations:

MyVar = setTimeout ("javascript function", milliseconds)

If the method has not been executed, we can use clearTimeout () to block it.

ClearTimeout (id_of_settimeout)

The return value obtained when id_of_setinterval calls the setTimeout () function. Using the return identifier as an argument, you can cancel the scheduled execution operation set by the setTimeout ().

Examples are as follows:

one hundred and twenty three

Click the button and wait 3 seconds before popping up "Hello".

Click the second button to prevent the execution of the pop-up function myFunction. (you must click 3 seconds ago)

Block popup of var myVar;function myFunction () {myVar = setTimeout (function () {alert ("Hello")}, 3000);} function myStopFunction () {clearTimeout (myVar);}

Output result:

If you click only the first button, a pop-up window will appear three seconds later:

If the second button is clicked within three seconds after the first button is clicked, no pop-up window will appear.
