onReady( )

Adds an event handler that runs when the dataset is ready.

Description

The onReady() function allows you to optionally perform actions right after the dataset has loaded its data from the collection and updated all connected page elements with their corresponding values.

Notes:
The dataset onReady event only fires after the page onReady event fires.
The onReady() function has the same functionality as the onReadyAsync() function. They differ in that onReady() is callback-based, whereas onReadyAsync() is promise-based.

This example demonstrates how both onReady() and onReadyAsync() functions do the same thing.

Copy Code

1$w.onReady(async () => {
2  //onReady
3  await $w("#myDataset").onReady( () => {
4    let hasNextItem =  $w("#myDataset").hasNext(); //true
5  } );
6
7  //onReadyAsync
8  await $w("#myDataset").onReadyAsync();
9  let hasNextItem =  $w("#myDataset").hasNext(); //true
10} );
