document.querySelectorAll
will thrown on any unsupported selector so you can simply use a try-catch
block.
Check if the browser supports document.querySelectorAll in JavaScript

Pergunta
Now although most modern browser support document.querySelectorAll()
, you may run into problems with older versions of Internet Explorer. The obvious way of checking if the browser supports a function would be:
if(document.querySelectorAll){
//some random code
}
But from what I understand some browsers like (IE8) don't support certain properties, like 'body *
'. Is there a better way to check if document.querySelectorAll('body *')
will actually work?

Check browser supports or not , without try-catch :
function QuerySelectors() {
return (document['querySelector']&&document['querySelectorAll'])!=null;
}
or
function QuerySelectors(){
return typeof(document['querySelector'])=='function'&&typeof(document['querySelectorAll'])=='function';
}

Use typeof to check it:
if(typeof(document.querySelectorAll) != 'undefined'){
//some random code
}
