window.close does not work

I discovered the reason for the problem that happens when the browser flap is reopened / resurrected, ie in Chrome when I reopen the window through the Ctrl + Shift + T shortcut.

As I'm testing this controller I exhaustively need to fill out a form with many fields, so I do not have to fill them again I reopen the tab from this shortcut, so when the window.close() command is executed the window value is not known , because the tab is orphan window (orphan window).

Thanks to everyone for the help, but only after completely changing the way I tested that I found the cause of the problem.

You can not use window.close on windows that were not opened by the script in question, and that's what the message is saying.

Remember that you have self.close() for the same window:

<a href="self.close ()">Fechar esta janela</a>

But in any case, browsers offer some restrictions on these uses to prevent abuse by restricting scripts to closing scripted windows, or with certain special conditions (depending on the implementation of each browser).

Simplifying a little:

• To use window.close , on the other hand, normally the window must have been opened by a script.

As the implementation varies a bit from case to case, if anyone has any further important considerations, please put in the comments that I increased the response

To use jQuery dialogs do the following:

$(seletor).dialog({
// opcoes que eu quero
});

To close the dialog you can use the button that is already available in the dialog or use the close command:

$(seletor).dialog("close");

One way I've done to avoid getting selected is to save the selection to a global variable:

window.meuDialogo = $(seletor).dialog({
// Minhas opcoes
});

function fechaDialogo (){
  window.meuDialogo.dialog("close");
}
