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]');
回答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.
