通过Javascript动态加载Css文件

Posted 2021-02-26

changed to detect sring sheet first, then to try object extension.

var CSSLoader = {
	addStylesheets: function(sheets, elm){
		var l = sheets.length;
		if( !l ) return;
		elm = $(elm) || $$('head')[0];
		if( !elm ) return;
 
		for( var i=0; i<l; i++){
			var sheet = sheets[i];
			var info = {
				rel: 'stylesheet',
				type: 'text/css',
				media: 'screen'
			}
                        if( Object.isString(sheet)){
                            Object.extend(info, {href: sheet});
                        }else{
                            try{
                                Object.extend(info, sheet);
                            }catch(e){
                                continue;
                            }
                        }
			var temp = new Element('link', info);
			elm.insert(temp);
		}
	}
};
