node.insertBefore()几乎等效:这是jQuery的作用: https://gist.github.com/kagagnon/a13de27760ba1af883c0#file-gistfile1-js-L6064

Here what jQuery does : https://gist.github.com/kagagnon/a13de27760ba1af883c0#file-gistfile1-js-L6064

before: function() {
    return this.domManip( arguments, function( elem ) {
        if ( this.parentNode ) {
            this.parentNode.insertBefore( elem, this );
        }
    });
}
