提问by Stewie Griffin
Is it possible to set a title in the window popup?
是否可以在弹出窗口中设置标题？
I have this in javascript:
我在javascript中有这个：
var popup = window.open('......');
popup.document.title = "my title";
but this does not work..still can't see any title
但这不起作用..仍然看不到任何标题
EDIT: the page popup is displaying is .aspx and it HAS a title tag, but still can't see that on the popup window..
编辑：显示的页面弹出窗口是 .aspx 并且它有一个标题标签，但在弹出窗口上仍然看不到。

Since popup.onloaddoes not seem to work, here is a workaround: http://jsfiddle.net/WJdbk/.
由于popup.onload似乎不起作用，这里有一个解决方法：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

I was having problems with the accepted answeruntil I realized that if you open an existing, slowpage that already has a <title>the browser will 1) set your title, then 2) once the document fullyloads it will (re)set the popup title with the "normal" value.
我对接受的答案有问题，直到我意识到如果你打开一个现有的、已经有一个缓慢的页面，<title>浏览器将 1) 设置你的标题，然后 2) 一旦文档完全加载它会（重新）设置弹出标题与“正常”值。
So, introducing a reasonable delay (function openPopupWithTitle):
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;
}

None of these answers worked for me. I was trying to open a popup with a PDF inside and kept getting permission denied trying to set the title using the above methods. I finally found another post that pointed me in the correct direction. Below is the code I ended up using.
这些答案都不适合我。我试图打开一个带有 PDF 的弹出窗口，并一直被拒绝尝试使用上述方法设置标题。我终于找到了另一篇文章，指出了正确的方向。下面是我最终使用的代码。

来源：当 Url 指向 PDF 文件时如何在弹出窗口中设置标题
var winLookup;
var showToolbar = false;
function openReportWindow(m_title, m_url, m_width, m_height)

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;

} else {
// if not loaded yet
setTimeout(checkPopup(m_url, m_title), 10); // check in another 10ms
}
}

Not sure if this will help,
不确定这是否会有所帮助，
function GetInput() {
var userInput;
var stringOutput;
userInput = prompt('What should the title be?', "");
stringOutput = userInput;
document.title = stringOutput;
}<button type="button" onclick="GetInput()">Change Title</button>回答by Ganesh Kumbhar

Try this, it will work.
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);
}
}
