One of the object in my JavaScript code is showing that it has "No Properties" when I check it in JS Debugger of chrome. I want to apply if statement on it. How can I do that. Because

JavaScript

if (wsdl != null || wsdl != undefined || wsdl != NaN)

is not working

Solution 1

when an object is on of these
1: null
2: undefined
3: 0
4: ""
it is called falsy value
so you can do this

JavaScript

if(!wsdl){
    //do something
}

if you are not sure wsdl is declared so you can do this:

JavaScript

if(!window['wsdl']){
    //do something
}
