I have a link on my site that opens a new window to a page that plays a very long audio file. My current script works fine to open the page and not refresh if the link is clicked multiple times. However, when I have moved to a seperate page on my site and click this link again, it reloads. I am aware that when the parent element changes, I will lose my variable and thus I will need to open the window, overiding the existing content. I am trying to find a solution around that. I would prefer not to use a cookie to achieve this, but I will if required.
My script is as follows:
function OpenWindow(){
if(typeof(winRef) == 'undefined' || winRef.closed){
//create new
winRef = window.open('http://samplesite/page','winPop','sampleListOfOptions');
} else {
//give it focus (in case it got burried)
winRef.focus();
}
}
You should first to call winRef = window.open("", "winPopup")
without URL - this will return a window, if it exists, without reloading. And only if winRef
is null
or empty window, then create new window.
Here is my test code:
var winRef;
function OpenWindow()
{
if(typeof(winRef) == 'undefined' || winRef.closed)
{
//create new
var url = 'http://someurl';
winRef = window.open('', 'winPop', 'sampleListOfOptions');
if(winRef == null || winRef.document.location.href != url)
{
winRef = window.open(url, 'winPop');
}
}
else
{
//give it focus (in case it got burried)
winRef.focus();
}
}
It works.
