ConstOnly call the listener if one of the given cmps have changed
Optionallazy: booleanfalse (default): Immediately fetch the values of all changed components.
true: Trigger the listener but don't fetch values until specifically requested.
This could reduce data traffic when only some components are required in the listener, due to
conditions or similar.
[SCENARIO 1] where lazy: true could be benefical
CmpUtils.onAnyCmpValueChanged(() => {
const useBigData = CmpSimpleBool.getValue();
if(useBigData) {
// only now the data will be retrieved from the server
const bigData = await CmpBigData.getValue();
}
}, [CmpBigData, CmpSimpleBool, CmpSimpleText], true);
[SCENARIO 2] where lazy: false could be benefical
CmpUtils.onAnyCmpValueChanged(() => {
// The data for both values has been fetched in the background, so no further server request is necessary
const bigData1 = await CmpBigData1.getValue();
const bigData2 = await CmpBigData2.getValue();
}, [CmpBigData1, CmpBigData2]);
Called whenever the value of at least 1 component has changed.
Returns an object that indicates which components have actually changed.
