Set title in the window popup
Is it possible to set a title in the window popup?
I have this in javascript:
var popup = window.open('......');
popup.document.title = "my 开发者_JAVA技巧title";
but this does not work..still can't see any title
EDIT: the page popup is displaying is .aspx and it HAS a title tag, but still can't see that on the popup window..
Since popup.onload does not seem to work, here is a workaround: 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 answer until I realized that if you open an existing, slow page that already has a <title> the browser will 1) set your title, then 2) once the document fully loads it will (re)set the popup title with the "normal" value.
So, introducing a reasonable delay (function 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.
Source: 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
}
}
You can use also
var popup = window.open('......');
popup.onload = function () {
popup.document.title = "my title";
}
Not sure if this will help,
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>var win= window.open('......');
win.document.writeln("<title>"+yourtitle+"</title>");
This works for me, tested in chromium browsers.
I ended up creating a setTitle method in my popup window and calling it from my parent page.
//popup page:
function setTitle(t) {
document.title = t;
}
//parent page
popupWindow.setTitle('my title');
Try this, it will work.
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);
}
}
加载中,请稍侯......
