window object method
allows you to open up new browser windows (popups). Various browser policies and user settings may prevent you from opening a popup (due to abuse of the technique for marketing purposes), but generally you should be able to open a new window if it was initiated by the user. Otherwise, if you try to open a popup as the page loads, it will most likely be blocked, because the user didn't initiate it explicitly.
accepts the following parameters.
Comma-separated list of features, such as:
|URL||to load in the new window|
|Name||Name of the new window, which can be used as the value of a form's target attribute|
|resizable||should the user be able to resize the new window|
|width||width of the popup |
|height||height of the popup|
|status||should the status bar be visible and so on|
returns a reference to the window object of the newly created browser instance.
Here's an example.
var popup = window.open('http://www.rookienerd.com', 'packt', 'width=300,height=300,resizable=yes');
popup points to the window object of the popup. You can check if popup has a falsy value, which means that the popup was blocked.
popup.close() //closes the new window.
It's best to stay away from opening new windows for accessibility and usability reasons. Alternatively this can be achieved by using a floating <div> inside the page.
window object methods like
to locate and position the browser window in the screen.
|window.moveTo(100, 100)||will move the browser window to screen location x = 100 and y = 100 (counted from the top left corner).|
|window.moveBy(10, -10)||will move the window 10 pixels to the right and 10 pixels up from its current location.|
|window.resizeTo(x, y)/ window.resizeBy(x, y)||accept the same parameters as the move methods but they resize the window as opposed to moving it.|
