How can you change a value in javascript from another webpage?

I've created a loop in JS and have a condition that say if(minute === 15), once the clock hits 15mins past (whatever) the condition is met.

I want to make that "15" a variable that can be changed from another webpage.

website.com/alarm Contains the loop

website.com/alarmConfig Contains a text field used to set the minute.

I originally was going to make that script read a notepad that has the value in it, but because the page will be running on a range of devices I need those browsers to be able to do that.

What would be the simpliest way of doing this? Doesn't need to be in real-time

You can make an Ajax call to "website.com/alarmConfig" webpage and then retrieve the value of the text field used to set the minute and then update the loop in "website.com/alarm". Also, you will make the call after the said duration is over and once you retrieve the updated value, you can run the loop again.

You can't do it. But you can use cookies or localStorage to share these variables.

For simple synchronous storage access HTML 5 introduces the localStorage attribute on the Window object:

localStorage["status"] = "Idling.";
