open multiple tabs on a single window by a single click using JavaScript

Question

I need to open multiple tabs on a single window, new window instance for a single link will not be a problem but when it comes to 20+ (which is my case) then 20+ new windows

Answer 1

Solotion: Use setTimeout! With more and more time values

javascript:
var a=document.location.href;
for (var i=0;i<50;i++){
    setTimeout('window.open(a)',i*200);
}
void(0);

This will clone the current tabs 50 times, even in Chrome! Unfortunately, in new Windows instead of new tabs. Silly Chrome :-)

Answer 2

I wasn't sure if you wanted the links to be open in a new window or not so I've included both possibilities;

Same Window

var linkArray = []; // your links
for (var i = 0; i < linkArray.length; i++) {
    // will open each link in the current window
    chrome.tabs.create({
        url: linkArray[i]
    });
}

chrome.tabs documentation

New Window

// will open a new window loaded with all your links
chrome.windows.create({
    url: linkArray
});

chrome.windows documentation

Regardless of which approach you use you will need to declare the tabs permission in your extension's manifest.

Answer 3

You can use target="_blank" attribute of a link for opening the corresponding page in new tab.
