javascript - 新しいウィンドウで DIV ボタンを開く

Answer 1

parent.location references the same window. And I don't know where you got the ideas for the other things you tried, but window.open seems to be what you're looking for:

<div onclick="window.open('http://google.com')" data-mce-onclick="">
  <button class="button"><font size=”6”&gt;Visit Google</font></button>
</div>

It's worth noting also that you're using very old and deprecated tags. center and font should be replaced with CSS styling.

Answer 2

You can use window.open documented here http://www.w3schools.com/jsref/met_win_open.asp
