Javascript Window.open（）将在safari的新选项卡中打开

我正在使用window.open打开一个模式弹出窗口，它在chrome和ie中作为模式弹出窗口打开，但在safari中它作为新选项卡打开，请帮助

var popUpObj;
    function showModalPopUp()
    {
    popUpObj=window.open("PopUp.htm",
    "ModalPopUp",
    "toolbar=no," +
    "scrollbars=no," +
    "location=no," +
    "statusbar=no," +
    "menubar=no," +
    "resizable=0," +
    "width=100," +
    "height=100," +
    "left = 490," +
    "top=300"
    );
    popUpObj.focus();
    LoadModalDiv();
    }

也许把它放在一个小盒子里，让它在safari上工作打开谷歌搜索——但我看到一些人说你需要使用var newTab=safari.self.browserWindow.openTab；对于safarii，我尝试了，但仍然在一个新的选项卡而不是窗口中打开它
