Question

是否可以在弹出窗口中设置标题？

我在javascript中有这个：

var popup = window.open('......');
popup.document.title = "my title";

但这不起作用..仍然看不到任何标题

编辑：页面弹出窗口显示的是.aspx，它有一个标题标签，但仍然无法在弹出窗口中看到..

Answer 1

由于popup.onload似乎不起作用，因此这是一种解决方法：http://jsfiddle.net/WJdbk/。

var win = window.open('', 'foo', ''); // open popup

function check() {
    if(win.document) { // if loaded
        win.document.title = "test"; // set title
    } else { // if not loaded yet
        setTimeout(check, 10); // check in another 10ms
    }
}

check(); // start checking

我遇到了accepted answer的问题，直到我意识到如果你打开现有的慢页面已经有<title>，浏览器将会设置你的标题，然后2）一旦文件完全加载，它将（重新）设置弹出标题的“正常”值。

因此，引入合理的延迟（函数openPopupWithTitle）：

var overridePopupTitle = function(popup, title, delayFinal, delayRepeat) {
    // https://stackoverflow.com/a/7501545/1037948
    // delay writing the title until after it's fully loaded,
    // because the webpage's actual title may take some time to appear
    if(popup.document) setTimeout(function() { popup.document.title = title; }, delayFinal || 1000);
    else setTimeout(function() { overridePopupTitle(popup, title); }, delayRepeat || 100);
}
var openPopupWithTitle = function(url, title, settings, delay) {
    var win = window.open(url, title, settings);
    overridePopupTitle(win, title, delay);
    return win;
}

这些答案都不适合我。我试图在里面打开一个带有PDF的弹出窗口并且不断尝试使用上述方法设置标题。我终于发现另一篇文章指出了我正确的方向。以下是我最终使用的代码。

来源：How to Set the Title in Window Popup When Url Points to a PDF File

    var winLookup;
    var showToolbar = false;

    function openReportWindow(m_title, m_url, m_width, m_height)
    {
        var strURL;
        var intLeft, intTop;

        strURL = m_url;

        // Check if we've got an open window.
        if ((winLookup) && (!winLookup.closed))
            winLookup.close();

        // Set up the window so that it's centered.
        intLeft = (screen.width) ? ((screen.width - m_width) / 2) : 0;
        intTop = (screen.height) ? ((screen.height - m_height) / 2) : 0;

        // Open the window.
        winLookup = window.open('', 'winLookup','scrollbars=no,resizable=yes,toolbar='+(showToolbar?'yes':'no')+',height=' + m_height + ',width=' + m_width + ',top=' + intTop + ',left=' + intLeft);
        checkPopup(m_url, m_title);

        // Set the window opener.
        if ((document.window != null) && (!winLookup.opener))
            winLookup.opener = document.window;

        // Set the focus.
        if (winLookup.focus)            
            winLookup.focus();
    }

    function checkPopup(m_url, m_title) {     
        if(winLookup.document) { 
            winLookup.document.write('<html><head><title>' + m_title + '</title></head><body height="100%" width="100%"><embed src="' +m_url + '" type="application/pdf" height="100%" width="100%" /></body></html>');
        } else { 
            // if not loaded yet
            setTimeout(checkPopup(m_url, m_title), 10); // check in another 10ms
        }
    }

Answer 5

您也可以使用

var popup = window.open('......');
popup.onload = function () {
popup.document.title = "my title";
}

Answer 6

var win= window.open('......');
win.document.writeln("<title>"+yourtitle+"</title>");

这对我有用，已经在铬浏览器中进行了测试。

Answer 7

试试这个，它会起作用。

var timerObj, newWindow;

function openDetailsPopUpWindow(url) {
    newWindow = window.open(url, '', 'height=500,width=700,menubar=no,resizable=yes,scrollbars=yes');
    timerObj = window.setInterval("fun_To_ReTitle('~~newTitle~~ ')", 10);
}


function fun_To_ReTitle(newTitle){
    if (newWindow.document.readyState == 'complete') {
        newWindow.document.title=newTitle;
        window.clearInterval(timerObj);
    }
}
