To implement page loading, you need to use the reload() method. The purpose of this method is to reload the current document

reload() method

location.reload()

When we set the value of reload() to true, it will bypass the cache and re-download the document from the server, just like every time we click the browser's refresh button.

If this method is set to false or no parameters are set, it will use the If-Modified-Since in the HTTP header to detect whether the document on the server has changed. If the document has changed, reload () will download the document again; if the document has not changed, this method will load the document from the cache.

Example:

<body>
		<input type="button" value="刷新" onclick="document.location.reload(true);">
		<p>点击上面的按钮会刷新页面</p>
		<img  src="/static/imghwm/default1.png"  data-src="images/1.jpg"  class="lazy"    style="max-width:90%" alt="How to make page reload in JavaScript" >
</body>
