jQuery 与 JS 命令参照表

我整理了一张《jQuery 与 JS 命令参照表》，包括 Select，Content，CSS，DOM，Event 五个常见分类。

	insertAfter	newEl.insertAfter(el)	el.parentNode.insertBefore(newEl,el.nextSibling)
	DOM ready	$(document).ready(eventHandler);	document.addEventListener('DOMContentLoaded', eventHandler);
	load	$(window).load(function() {}); $(window).on('load',function(){});	window.onload = function(){}; window.addEventListener('load', function(){});
	Ajax	el.load(url, callback)	fetch(url).then(data => data.text() ).then(data=>{ el.innerHTML = data }).then(callback)
	iframe	$iframe.contents()	iframe.contentDocument
