问如何使用Javascript更改CSS样式以使链接与普通文本相同？

EN

a {
  color: inherit !important;
  text-decoration: inherit !important;
}

var anchors = document.getElementsByTagName('a');
anchors = Array.prototype.slice.call(anchors);
anchors.forEach(function (anchor) {
    anchor.style.textDecoration = 'none';
    anchor.style.color = 'black'; // to taste
    // et. al. You'll need to define these CSS rules.
});

Array.prototype.forEach.call(document.getElementsByTagName('a'), function (anchor) {/* CSS */});

var sss = Components.classes['@mozilla.org/content/style-sheet-service;1'].getService(Components.interfaces.nsIStyleSheetService);
var ios = Components.classes['@mozilla.org/network/io-service;1'].getService(Components.interfaces.nsIIOService);
var css = 'a {color: inherit !important; text-decoration: none !important; }';
//var cssEnc = 'data:text/css;base64,' + window.btoa(css);
var cssEnc = encodeURIComponent(css);
var cssUri = makeURI('data:text/css,' + cssEnc);
sss.loadAndRegisterSheet(cssUri, sss.USER_SHEET);
//when want to unregister run this:
//sss.unregisterSheet(cssUri, sss.USER_SHEET);
