在JavaScript中检测浏览器窗口

Question

I'm a newbie in javascript and I've to do the following operation: I have an asp .net application which load in a new window browser another content.

Through javascript, I need to refresh the popup which i opened before, but I don't know how I can find that new window.

I tried a simple window.location.reload(true); but this will cause a refresh only of the main browser window which launched the popup. Instead my intent is to refresh only the popup window.

Answer 1

If you open the window with window.open() , grab its return value. That's a reference to the window object of the popup. From there you can call location.reload() . For example, this will open a window and then reload it again:

var popup = window.open('/somepage');
popup.location.reload(true);

Answer 2

When you open the window, give it a name (or store the return value of the window). Then, instead of window.location.reload , call name.location.reload where name is the name you gave the window.

Answer 3

Store a reference to your popup window and then instead of calling the location.reload() function on your main window, call it on the popup window, like this:

var myNewWindow = window.open(...);
myNewWindow.location.reload(true);

Answer 4

Are you creating the new window using Javascript? if you are using window.open() , that function returns a reference to the new window, So you can do something like this:

var newWin = window.open();
newWin.location.reload(true);
