Interval events (Timing functions in JavaScript) allow the user to run APIs and DB queries periodically. You can configure these using the setInterval
and clearInterval
functions.
Say you want to update data on Table without re-running the API / or using a refresh button, you can use the setInterval
function.
In this example, we’ll be using the switch widget (Switch1
) to control this function and a table widget that uses the getData
query.
Now on Switch1
widget’s onChange
property, we use the following JS:
{{
(() => {
if (Switch1.isSwitchedOn) {
setInterval(() => getData.run(), 2000, "autoupdate");
} else {
clearInterval("autoupdate");
}
})()
}}
Here, the setInterval
function calls the getData
query every 2 seconds when the switch widget is turned on, else, it removes the autoupdate (id) interval.
