I am working with ZK and I want to get the id of the a zk element from js.
I have used differents ways:

Declaring the component like native html and it gets the id from js but it isn't correct.
I have declared the element using the html tags of ZK but isn't correct too.
I have seen some functions like Component.getFellow('component\_name') and finally I have read about the UUID and use some example codes but I can't the element id for example:

```
<label id=titleBook/>

```

from javaScript.

any idea?
Thank you.
