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

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.
