How to ignore self signed certificate in XmlHttpRequest

I am working on a project which is written in javascript. I can see that for requesting, XMLHttpRequest object has been created.

It is working fine for "http" requests but fails for "https". Since I am debugging it in the Development environment, I just want to know how to ignore self-signed certificate in XmlHttpRequest objects?

While searching I have found this,

httpreq = new ActiveXObject("Msxml2.ServerXMLHTTP.3.0");httpreq.setOption(2, 13056);

But the answer is not working for morden browsers like Microsoft edge, chorme...

I have also found this, and it clearly says the setOption() can be used for ignoring ssl certificates.

One difference I can see in my code is that I an creating the httpreq using:

httpreq = new xmlhttprequest();//This is for chorme and Firefox

So is there any way I can ignore self-signed certificates in XmlHttpRequest?
