Hi everyone,

I’m having some trouble trying to use the parameter that are recieved from another Page.

Currently I’m using

```javascript
router.push("view", {id: 3})

```

Then after that on the JS on the view Page im recieving it as this.Parameter.

The problem i have is that i have no way to acces the data from js. on the UI its fine. but not from js. if i console.log(this.Parameter.value) its null.

Not sure what i an doing wrong.

Thanks.

Hi Franz,  
`this.Parameter` is a special kind of beast and you shouldn’t really approach it as a regular variable.

Instead of `console.log`ging it directly, you should do this inside of your receiving page JS:

```auto
this.Parameter.onValueChanged(module,function(param) {
    console.log('Incoming param changed to: ' + JSON.stringify(param));
});

```

Please also note that the value only changes when it changes. Meaning, if you `router.goBack()` from the receiving page and then open it again with the same parameter, the `.onValueChanged` will not trigger (since the value didn’t change).
