你可以在形式上使用技巧：

$(function () {
    $('#btn').click(function () {
        openNewTab("http://stackoverflow.com")
        return false;
    });
});

function openNewTab(link) {
    var frm = $('<form   method="get" action="' + link + '" target="_blank"></form>')
    $("body").append(frm);
    frm.submit().remove();
}

如果您只想打开外部链接（指向其他站点的链接），那么JavaScript/jQuery的这一功能很好：

$(function(){
    var hostname = window.location.hostname.replace('www.', '');
    $('a').each(function(){
        var link_host = $(this).attr('hostname').replace('www.', '');
        if (link_host !== hostname) {
            $(this).attr('target', '_blank');
        }
    });
});

不知怎么的，一个网站可以做到这一点

我将在一定程度上同意下面的人的观点（此处转述）：“对于现有网页中的链接，如果新网页与现有网页是同一网站的一部分，浏览器将始终在新选项卡中打开链接。”至少对我来说，这条“通用规则”适用于Chrome、Firefox、Opera、Internet Explorer、Safari、SeaMonkey和Konqueror。

不管怎样，有一种不那么复杂的方法可以利用对方所呈现的内容。假设我们讨论的是您自己的网站（下面的“thisite.com”），您希望在其中控制浏览器的功能，那么，下面，您希望“specialpage.htm”为空，其中完全没有HTML（这样可以节省从服务器发送数据的时间！）。

 var wnd, URL; // Global variables

 // Specifying "_blank" in window.open() is SUPPOSED to keep the new page from replacing the existing page
 wnd = window.open("http://www.thissite.com/specialpage.htm", "_blank"); // Get reference to just-opened page
 // If the "general rule" above is true, a new tab should have been opened.
 URL = "http://www.someothersite.com/desiredpage.htm";  // Ultimate destination
 setTimeout(gotoURL(), 200);  // Wait 1/5 of a second; give browser time to create tab/window for empty page


 function gotoURL()
 { 
   wnd.open(URL, "_self");  // Replace the blank page, in the tab, with the desired page
   wnd.focus();             // When browser not set to automatically show newly-opened page, this MAY work
 }

有很多答案副本建议使用“_blank”作为目标，但我发现这并不奏效。正如Prakash指出的，这取决于浏览器。但是，您可以向浏览器提出某些建议，例如窗口是否应具有位置栏。

如果你提出了足够多的“类似标签的东西”，你可能会得到一个标签，正如Nico对铬的这个更具体问题的回答：

window.open('http://www.stackoverflow.com', '_blank', 'toolbar=yes, location=yes, status=yes, menubar=yes, scrollbars=yes');

免责声明：这不是万能药。这仍然取决于用户和浏览器。现在，至少您为希望窗口的外观指定了一个首选项。

这将创建一个虚拟的a元素，并为其提供target=“_blank”，因此它将在一个新选项卡中打开，为其提供适当的URL href，然后单击它。

function openInNewTab(href) {
  Object.assign(document.createElement('a'), {
    target: '_blank',
    rel: 'noopener noreferrer',
    href: href,
  }).click();
}

然后你可以像这样使用它：

openInNewTab("https://google.com");

重要说明：

这必须在所谓的“可信事件”回调过程中调用，例如，在单击事件期间（在回调函数中不需要直接调用，但在单击操作期间）。否则，浏览器将阻止打开新页面。

如果您在某个随机时刻手动调用它（例如，在一段时间内或在服务器响应之后），它可能会被浏览器阻止（这很有道理，因为这会带来安全风险，并可能导致用户体验不佳）。
