Javascript in Footer executing in 3 Times

[Elderberg]

Hi There,

I'm using a Chart Datapage and in the search footer I have the following which i'm testing something weird.

<script>
document.addEventListener('DataPageReady', function (event) {
alert("Hello World");
});
</script>

The hello world executes 3 times upon loading..

Can someone advise i I would be able to limit the execution to run just once?

Hi @Elderberg,

Upon check this with my end it seems that it is working properly, you may check the behavior on this link: https://c0dcv045.caspio.com/dp/aa4a60001bbdd474c93346849048.

Try to clear your cache or use other browser and try access it on Deployed DataPage URL.

I hope this helps.

Hi @Elderberg

This is not related to cache or cookies. This is the default behavior of "DataPageReady" event.
You need to clean this event after executing. Also, you need to define functions out of event listener to increase the performance.

Here is the example of the code: 
 

<script>
function someFunc() {
	alert("Hello World");
	document.removeEventListener("DataPageReady", someFunc);
}

document.addEventListener('DataPageReady', someFunc);
</script>
