In JavaScript programming, location.reload is often used to refresh the page.

Example:

window.location.href=window.location.href;
window.location.reload;
Copy after login

After testing, these two sentences can replace location.reload(true);
in some cases without a retry dialog box to achieve the refresh effect.

There are many ways to refresh the page in js. There is a location.reload() function in js, which can achieve the function we want.
window.location.reload(true) //The browser re-requests resources from the server, and the cache tag will not be included in the http request header.

Example 1, refresh the current page

   
<script>
window.location.reload();
</script>
Copy after login

Example 2, JS method to refresh iframe
Use iframe’s name attribute positioning

   
<input type="button" name="Button" value="Button" onclick="document.frames(&#39;ifrmname&#39;).location.reload()">
或
<input type="button" name="Button" value="Button" onclick="document.all.ifrmname.document.location.reload()">
Copy after login

Example 3, first, define an iframe

<iframe method="post" id ="IFrameName" src="aa.htm" ></iframe>
Copy after login

aa.htm page content:

<input type ="button" value ="刷新" onclick ="aa()"/>
function aa() { (php中文网 m.sbmmt.com 编辑整理)
//parent.location.replace(parent.location.href);//服务器端重新创建页面
parent.document.location.reload();//相当于F5
//window.location.href(parent.location.href);//iframe内容重定向
}
Copy after login

window.location. reload;
If you submit data during refresh, a dialog box will appear!

Solution:

   
window.location.href=window.location.href;
window.location.reload;
