只是想知道谷歌浏览器是否会在某个时候支持 window.focus()。当我说支持时，我的意思是让它发挥作用。对它的调用不会失败，它只是什么都不做。所有其他主流浏览器都没有这个问题:FireFox、IE6-IE8 和 Safari。

我有一个用于管理浏览器窗口的客户端类。当我第一次创建一个窗口时，该窗口进入焦点，但随后尝试将焦点置于该窗口时却不起作用。

据我所知，这似乎是一种避免烦人的弹出窗口的安全功能，而且它似乎不是 WebKit 问题，因为它在 Safari 中有效。

我知道有人提出的一个想法是关闭窗口然后重新打开它，但这是一个糟糕的解决方案。谷歌搜索显示我似乎不是唯一对此感到沮丧的人。

为了 100% 清楚，我的意思是新窗口，而不是选项卡(选项卡不能从我读过的内容中聚焦)并且所有打开的窗口都在同一个域中。

除了我上面提到的不好的想法之外，还有什么想法和解决方法吗？

Chromium 项目上记录了一个关于此的错误，请查看 here .感谢您发布Rich .

MyCompany = { UI: {} }; // Put this here if you want to test the code. I create these namespaces elsewhere in code.

MyCompany.UI.Window = new function() {
    // Private fields
    var that = this;
    var windowHandles = {};

    // Public Members
    this.windowExists = function(windowTarget) {
        return windowTarget && windowHandles[windowTarget] && !windowHandles[windowTarget].closed;
    }

    this.open = function(url, windowTarget, windowProperties) {
        // See if we have a window handle and if it's closed or not.
        if (that.windowExists(windowTarget)) {

            // We still have our window object so let's check if the URLs is the same as the one we're trying to load.
            var currentLocation = windowHandles[windowTarget].location;

            if (
                (
                    /^http(?:s?):/.test(url) && currentLocation.href !== url
                )
                    ||
                (
                    // This check is required because the URL might be the same, but absolute,
                    // e.g. /Default.aspx ... instead of http://localhost/Default.aspx ...
                    !/^http(?:s?):/.test(url) &&
                    (currentLocation.pathname + currentLocation.search + currentLocation.hash) !== url
                )
            ) {
                // Not the same URL, so load the new one.
                windowHandles[windowTarget].location = url;
            }

            // Give focus to the window. This works in IE 6/7/8, FireFox, Safari but not Chrome.
            // Well in Chrome it works the first time, but subsequent focus attempts fail,. I believe this is a security feature in Chrome to avoid annoying popups.
            windowHandles[windowTarget].focus();
        }
        else
        {
            // Need to do this so that tabbed browsers (pretty much all browsers except IE6) actually open a new window
            // as opposed to a tab. By specifying at least one window property, we're guaranteed to have a new window created instead
            // of a tab.
            windowProperties = windowProperties || 'menubar=yes,location=yes,width=700, height=400, scrollbars=yes, resizable= yes';
            windowTarget = windowTarget || "_blank";

            // Create a new window.
            var windowHandle = windowProperties ? window.open(url, windowTarget, windowProperties) : window.open(url, windowTarget);

            if (null === windowHandle) {
                alert("You have a popup blocker enabled. Please allow popups for " + location.protocol + "//" + location.host);
            }
            else {
                if ("_blank" !== windowTarget) {
                    // Store the window handle for reuse if a handle was specified.
                    windowHandles[windowTarget] = windowHandle;
                    windowHandles[windowTarget].focus();
                }
            }
        }
    }
}

最佳答案

我一直在努力解决这个问题。我想要对另一个窗口的引用，所以我发布了:

otherWinRef = window.open("","OtherWindow");

但是，当我发出此命令时，浏览器会将焦点切换到 OtherWindow。我认为这可以通过这样做来解决:

otherWinRef = window.open("","OtherWindow");
window.focus();

但是 window.focus() 没有效果。我试过:

otherWinRef = window.open("","OtherWindow");
setTimeout(window.focus,0);

但是 window.focus() 调用仍然没有效果。

我通过将以下代码添加到 OtherWindow 的源代码来解决这个问题。

function Bounce(w) {

        window.blur();
        w.focus();
}

然后我将主窗口中的代码更改为:

otherWinRef = window.open("","OtherWindow");
otherWinRef.Bounce(window);
