How do you open a new tab in chrome using HTML/JS?

I tried this code

window.open('page2.开发者_Python百科html','_newtab');

And all it opened was a new window. How do I open a new tab?

This is a browser setting and not something you can control with code. In my browser, your "window.open" will open a new tab, because that's what I have mine set up to do. In others' browsers, it might open a new window.

You can do this easily. See the answer here.

I don't think you can, from HTML / Javascript, indicate that a page should be opened in a new tab.

(In fact, your page might be opened to a new window, or to a new tab, depending on the configuration of the browser)
