I have a script that loops through multiple urls and opens them in a new tab. It used to work but now only opens the first one. There's even a w3schools test editor that supposedly opens multiple windows, and it also fails after the first one:
.asp?filename=tryjsref_win_open6
However, if I step through in debug mode and reset the focus to to original tab each time, it does open each window. So my question is, how do I open multiple windows(tabs) but keep the focus on my window with the original script? It used to do it that way, but now, as soon as a new tab is added, it gets the focus, and the script stops opening windows. Here's the full w3schools failing script:
<!DOCTYPE html>
<html>
<body>
<p>Click the button to open multiple windows.</p>
<button onclick="myFunction()">Open Windows</button>
<script>
function myFunction() {
window.open("/");
window.open("/");
}
</script>
</body>
</html>

- Don't omit the "window name" argument, use e.g. "_blank" as the name, or give an unique name for every window. – Teemu Commented Aug 24, 2018 at 15:54
- 1 I believe chrome has a security feature which needs at least one user action per window.open, I might be wrong. – Daniel Sharp Commented Aug 24, 2018 at 15:55
- 1 Firefox opened two windows for me; Chrome and Safari only opened the first one. Chrome additionally shows a "Popup blocked" message, allowing me to disable that security feature; @FZs is it possible you've already disabled it? – Daniel Beck Commented Aug 24, 2018 at 16:20

- @FZs yeah, "Enabled" means you've enabled popups, i.e. disabled the security feature (of blocking popups). Weirdly confusing UI on Chrome's part, there.... – Daniel Beck Commented Aug 24, 2018 at 16:35

Reset to default 3As noted in another answer and the ments, it is a security feature.
It is worth adding, however, that you can disable it (on a per-site basis): simply click the small "popup blocker" icon at the right end of the address bar and enable popups from the current site.
Afterwards, feel free to shoot as many window.open's as you need.
I think as @Daniel Sharp said, there is a security feature in chrome. It works fine in FF and IE.
It works if I follow below steps:
- Click Open Windows (A new window will open)
- Click on inital browser tab
- Click somewhere on the page (Except Open Windows button)
- Click on Open Windows again (IT works this time - two windows are open)
The window name should be unique. Otherwise, the same page will refresh
function myFunction() {
window.open("https://www.google./","_google","height=200,width=150");
window.open("https://www.w3schools./","_w3schools","height=200,width=150");
}
