The browser value of such a property is a Javascript array.
There is one difference though. In order to be able to send fine-grained updates to the client/browser, those values are 'watched'. That means that whenever you assign a completely new javascript array directly to the property (or if you assign a new object/array into one element of it or nested on any level), that new value (reference) you assign will not be 'watched' directly; you have to take/read it back from the property (which will give you an equivalent 'watched' value) before using it further in code.
For example:
| Code Block | ||||
|---|---|---|---|---|
| ||||
var newPropertyValue = [ 1, 2, 3 ];
// here you assign a new array to the property
elements.myCustomComponent.myArrayProperty = newPropertyValue;
// here you update the reference that you want to use later in code with the 'watched' new value
newPropertyValue = elements.myCustomComponent.myArrayProperty ;
(...then later on, maybe during another event handler execution...)
// this modification will be detected because it's using the new 'watched' value you got from elements.myCustomComponent.myArrayProperty after it was assigned - and the change will be sent to the browser
newPropertyValue[1] = 5; |
| Code Block | ||||
|---|---|---|---|---|
| ||||
var newPropertyValue = {};
// here you assign a new array to the property
elements.myCustomComponent.myArrayProperty = newPropertyValue;
(...then later on, maybe during another event handler execution...)
// this will modify the value in newPropertyValue but myCustomComponent.myArrayProperty will not be aware of that to send changes to client/browser
newPropertyValue[1] = 5; |
