jquery - How to differentiate between DOM object and JavaScript object

Question

I tried to find out which is a dom object or which is a javascript object

var domObj =document.getElementById('lga');

typeof domObj

"object"

var jsObj = {name:"BP"}

typeof jsObj

"object"

Then how do I identify which is a dom object or js object.

Answer 1

You can use

domObj instanceof HTMLElement; // true

It will be false for

jsObj instanceof HTMLElement; // false

---

In an if it would look like this

if (domObj instanceof HTMLElement) {
  // ...
}
else {
  // ...
}

You can learn more about your objects by inspecting their constructor property

document.body.constructor; // function HTMLBodyElement() { [native code] }
