How to refresh another page using javascript without opening the same page in a new tab
提问by Nayana_Das
Is it possible to refresh a page from another page using Javascript or JQuery without opening the same page in a new tab.
是否可以使用 Javascript 或 JQuery 从另一个页面刷新页面，而无需在新选项卡中打开同一页面。
JS:
JS：
var newtab = window.open('http://localhost:8081/app/home');
newtab.document.location.reload(true);
I tried the above, but here, it will open a new tab, with the same page, which is already opened in the browser.
我尝试了上述操作，但在这里，它将打开一个新选项卡，该选项卡与浏览器中已打开的页面相同。
Please suggest a method.

I got the idea from a previous Question, here they used window Object Reference to reload the popup window, but for me it wont work, because, the parent window and child window runs in 2 different ports. So using the same trick, what i did is :
我从上一个问题中得到了这个想法，在这里他们使用窗口对象引用来重新加载弹出窗口，但对我来说它不起作用，因为父窗口和子窗口在 2 个不同的端口中运行。所以使用同样的技巧，我所做的是：
HTML:
HTML：
<a onclick="openNewTab()">app2</a>
<a onclick="refreshExistingTab()">Refresh</a>
JS:
JS：
<script>
var childWindow = "";
var newTabUrl="http://localhost:8081/app/home";
function openNewTab(){
childWindow = window.open(newTabUrl);
}
function refreshExistingTab(){
childWindow.location.href=newTabUrl;
}
</script>
refreshExistingTab() this instend of refreshExistingTab
refreshExistingTab() 这就是 refreshExistingTab

take a look at https://developer.mozilla.org/en-US/docs/Web/API/Window.openbasically if you do window.open and specify a window name it will overwrite that window with the url you provided. so if you open the page each time with same window name, it should overwrite it each time you do it again from that other page.
看看https://developer.mozilla.org/en-US/docs/Web/API/Window.open基本上如果你做 window.open 并指定一个窗口名称，它将用你提供的 url 覆盖该窗口。因此，如果您每次都使用相同的窗口名称打开该页面，则每次从该其他页面再次打开该页面时，它都应该覆盖它。
