调整来自不同域的 url 的窗口大小时，javascript 访问被拒绝

我有一个自定义函数，可以从不同的网址打开一个到屏幕中心的窗口。在我当前的情况下，我正在打开我的域之外的网址。这是我的职责。

function wopen(url, name, w, h) {
    w += 32;
    h += 96;
    wleft = (screen.width - w) / 2;
    wtop = (screen.height - h) / 2;
    if (wleft < 0) {
        w = screen.width;
        wleft = 0;
    }
    if (wtop < 0) {
        h = screen.height;
        wtop = 0;
    }
    var win = window.open(url,
                name,
                'width=' + w + ', height=' + h + ', ' +
                'left=' + wleft + ', top=' + wtop + ', ' +
                'location=no, menubar=no, scrollbars=yes');
    // +
    //'status=no, toolbar=no, scrollbars=no, resizable=yes');
    win.resizeTo(w, h);
    win.moveTo(wleft, wtop);
    win.focus();
}

这在 IE6 和 FF 上完美运行，但在 IE7 上不起作用

I have a custom function that will open a window to the center of the screen from a different url. On my current case I am opening a url outside my domain. This is my function.

function wopen(url, name, w, h) {
    w += 32;
    h += 96;
    wleft = (screen.width - w) / 2;
    wtop = (screen.height - h) / 2;
    if (wleft < 0) {
        w = screen.width;
        wleft = 0;
    }
    if (wtop < 0) {
        h = screen.height;
        wtop = 0;
    }
    var win = window.open(url,
                name,
                'width=' + w + ', height=' + h + ', ' +
                'left=' + wleft + ', top=' + wtop + ', ' +
                'location=no, menubar=no, scrollbars=yes');
    // +
    //'status=no, toolbar=no, scrollbars=no, resizable=yes');
    win.resizeTo(w, h);
    win.moveTo(wleft, wtop);
    win.focus();
}

This works perfectly on IE6, and FF but not on IE7

问题在于您尝试打开具有单独域的窗口，这在 IE7 及更高版本中被视为安全问题。本质上，当您打开该新窗口时，它会创建一个新进程并使您的进程保持独立，因此您无法再操作该其他窗口。

因此，一旦您使用与您自己的域不同的域打开新窗口，您就会失去对它的控制。我看不出有什么办法可以在不调整最终用户计算机的情况下改变这一点。

嗯，显然你可以通过打开一个你可以控制的窗口来解决这个问题，然后将 window.location.href 更改为你的网址。试试这个：

function wopen(url, name, w, h) {
    w += 32;
    h += 96;
    wleft = (screen.width - w) / 2;
    wtop = (screen.height - h) / 2;
    if (wleft < 0) {
        w = screen.width;
        wleft = 0;
    }
    if (wtop < 0) {
        h = screen.height;
        wtop = 0;
    }
    var win = window.open('about:blank', // <- Note about:blank
                name,
                'width=' + w + ', height=' + h + ', ' +
                'left=' + wleft + ', top=' + wtop + ', ' +
                'location=no, menubar=no, scrollbars=yes');
    // +
    //'status=no, toolbar=no, scrollbars=no, resizable=yes');
    win.location.href = url;
    win.resizeTo(800, 150);
    win.moveTo(wleft, wtop);
    win.focus();
}
wopen('http://www.yahoo.com/', 'yahoo', 250, 250);

我不知道这是否是一个黑客；我很惊讶它是如此容易解决，至少可以更改窗口大小等。但是，它可以工作（至少在 IE8 上）。

The issue is that you are attempting to open a window with a separate domain, which in IE7 and higher is considered a security issue. Essentially, when you open that new window, it creates a new process and leaves your process separate, so you can no longer manipulate that other window.

So, once you open that new window with a domain different from your own, you lose control of it. I don't see a way to change this without adjusting the end-users computer.

EDIT

Hmm, apparently you can get around this by opening a window that you do have control of, then changing the window.location.href to your url. Try this:

function wopen(url, name, w, h) {
    w += 32;
    h += 96;
    wleft = (screen.width - w) / 2;
    wtop = (screen.height - h) / 2;
    if (wleft < 0) {
        w = screen.width;
        wleft = 0;
    }
    if (wtop < 0) {
        h = screen.height;
        wtop = 0;
    }
    var win = window.open('about:blank', // <- Note about:blank
                name,
                'width=' + w + ', height=' + h + ', ' +
                'left=' + wleft + ', top=' + wtop + ', ' +
                'location=no, menubar=no, scrollbars=yes');
    // +
    //'status=no, toolbar=no, scrollbars=no, resizable=yes');
    win.location.href = url;
    win.resizeTo(800, 150);
    win.moveTo(wleft, wtop);
    win.focus();
}
wopen('http://www.yahoo.com/', 'yahoo', 250, 250);

I don't know if this is a hack or not; I'm surprised it's that easy to get around, at least for changing window resize and whatnot. But, it works (at least on IE8).
