How to update another page that is open in PHP, javascript or jquery

Question

Good afternoon, everyone!

I’m new to programming.

Good! I would like to know how to update (refresh) another that is open through a function be it in php, javascript or jquery.

Example: I have a 01.php page that contains an input and a buttom. When you click on the button, it updates the 02.php page that will be open.

Thank you in advance!

Hi to reload a browser tab first you need to grab the open window reference with function window.open();.

Example, your JS:

    var url = "https://www.google.com/search?source=hp&ei=1eefXJ7dFtrF5OUPjKer4Ag&q=random+number&oq=random+num&gs_l=psy-ab.1.0.0i131j0l2j0i203l2j0l5.44842.46396..47369...2.0..0.179.1255.0j11......0....1..gws-wiz.....0..35i39j0i67j0i10.KgraaLNVsIA";
    var childWindow = window.open(url);

For testing:

<input type="button" onclick="childWindow.location = url;" value="Reload Popup Window">

Do not use childWindow.location.reload(); as mentioned because browsers block access Cross Origin instead use childWindow.location = url; as I did. You can also call the function childWindow.close(); to close the window.

Unfortunately this is not possible if you did not open the tab.

The way to update the page would be through a window.location.reload() in Javascript. However, the control of tabs is completely in the hands of the browser if the user opened these tabs on his own.

Now, the simplest way to maintain control over one of the tabs is by opening through the Javascript itself inside the page by clicking on the link:

const janela = window.open('url', '_blank')
janela.location.reload()

See that you now have control of the tab through the variable janela, but this is not guaranteed to open a tab, since the full control of tabs and windows is done by the browser and each implements the _blank differently.

Still, be careful because you will only be able to control the other pages from one original page, which opened the others.
