Detection of Multiple Monitors

Copy linkTweet thisAlerts:
Feb 03.2004

I’m a bit of a Javascript newb here, so I’d appreciate any help I could get.

What I’m trying to do is this: The website I’m working on has numerous pop-up windows that are often open all at once and as such specifically placed around the screen by the user. Now I’m trying to implement a feature where the positions of each window are saved upon closing in a database and are used when the window is next opened.

But I’ve run into this problem regarding users with multiple monitors. Yes, I can open a window at (1200,0), thus placing it on the user’s second monitor. But what if (s)he unplugs the second monitor before returning? Then the pop-up appears well off the screen (assuming a 1024×768 resolution). Is there someway I can detect whether the point (1200,0) is a valid location on a screen, so I can revert the pop-up window’s location to some sort of default if it isn’t?

@96turnerriFeb 03.2004 — you could use screen.width or screen.height and use an if statement

if (screen.width <= 1024) {

popup ones locations blah blah

}

@blawauthorFeb 03.2004 — I'm sorry, but I'm not sure I understand your solution. Based on my test with several computers here in the office that have multiple monitors (2-4), screen.width always simply returns the width of the screen in which the Internet Explorer window is placed. Like, on a computer with two monitors at 1024, screen.width will always return 1024, never 2048.

@96turnerriFeb 03.2004 — what about this not sure what this will return as do not have 2 monitors on this pc

screen.availWidth

@blawauthorFeb 03.2004 — No, that's the problem. Neither screen.width nor screen.availWidth work. The screen object seems to only ever refer to the primary screen and it seems only one screen object exists. Clearly, the window and document objects wouldn't work, and if there is a second screen object representing the available space on the second monitor, I certainly don't know how to access it.
