Compatibility of document.querySelectorAll in IE, Edge and Safari

Question

Reference answer: https://stackoverflow.com/a/38399344/5132413

Please refer my question and the answer linked above works only in Firefox, Chrome, and Opera.

I did some research and found that it (case insensitivity flag) isn't compatible. I need an equivalent in IE, Edge and Safari.

var divs = document.querySelectorAll('div[class^="foo" i]');

Answer 1

Since css level 4 is still in drafts, case-sensitivity selector is not compatible with most browsers. You may use filter method like this:

var divs = [].slice.call(document.querySelectorAll('div')).filter(function(el){
   return el.className.match(/^foo/i);
});

Update: Need to state that you can now use css4 selector.

document.querySelectorAll('div[class^="foo" i]');

See this link for browser compatibility.
