You don't need to use height, just make sure you use _blank, Without it, it opens in a new tab.
For a empty window:
window.open('', '_blank', 'toolbar=0,location=0,menubar=0');
For a specific URL:
window.open('http://www.google.com', '_blank', 'toolbar=0,location=0,menubar=0');

Use window.open():
<a onclick="window.open(document.URL, '_blank', 'location=yes,height=570,width=520,scrollbars=yes,status=yes');">
Share Page
</a>
This will create a link titled Share Page which opens the current url in a new window with a height of 570 and width of 520.

Just use window.open() function? The third parameter lets you specify window size.
Example
var strWindowFeatures = "location=yes,height=570,width=520,scrollbars=yes,status=yes";
var URL = "https://www.linkedin.com/cws/share?mini=true&url=" + location.href;
var win = window.open(URL, "_blank", strWindowFeatures);

Javascript Opening Windows
(In the example above, the first link opens a window with the name demo4. You don't see that name, but it's the name of the new window. The second link opens a different page into the same window, replacing the first page, since it also was target to demo4. ALSO, notice that I did something different in the second link by making the window object myWindow, and then adding another JavaScript command, after the semicolon, that give focus to myWindow.

That's because this isn't a full URL:
www.teladocc.com
It's a relative URL. The browser has no way of knowing the difference between www.teladocc.com and, say, index.html.
If you did this:
window.open('index.html')
Then you wouldn't really expect to go to http://index.html, would you?
Use a fully-qualified URL:
window.open('http://www.teladocc.com/pnc')

You can add the http protocol to the url, like this:
&TeledoccLogo = "<a onclick=""javascript:window.open('http://www.teladocc.com/pnc');iAddClickStat('Benefits_Teladocc_Link');return false;"" href='#'>

Non-standard features (that are not handled by Chromium or Electron) given in features will be passed to any registered webContents's did-create-window event handler in the options argument. frameName follows the specification of target located in the native documentation. When opening about:blank, the child window's WebPreferences will be copied from the parent window, and there is no way to override it because Chromium skips browser side navigation in this case.

Since "window" is a reference to the global object, the function is also a global variable, and can be referred to by just "open" (unless another variable with the same name is in the scope). It is traditionally written out as "window.open", which helps to distinguish it from "document.open".
