How to open a new tab in Background in Chrome using AppleScript

How to open a new tab in Background using AppleScript in chrome. Open a tab seems so easy, but I just can't find what can be called to open the tab in background, which means the active tab remains开发者_开发百科 the same.

You can save the active tab index in a variable and set it back after you created your tab:

tell application "Google Chrome"
    set activeIndex to get active tab index of window 1
    tell window 1
        set newTab to make new tab with properties {URL:"http://www.google.com/"}
    end tell
    set active tab index of window 1 to activeIndex
end tell
