窗口。Open (url, wndname, params)，它有三个参数。如果你不希望它在同一个窗口中打开，只需要设置一个不同的wndname。例如:

window.open(url1, "name1", params); // this open one window or tab
window.open(url1, "name2", params); // though url is same, but it'll open in another window(tab).

试试吧~~

为了确保链接在同一个选项卡中打开，您应该使用window.location.replace()

请看下面的例子:

window.location.replace("http://www.w3schools.com");

   Just Try in button.

   <button onclick="location.reload();location.href='url_name'" 
   id="myButton" class="btn request-callback" >Explore More</button>

   Using href 

  <a href="#" class="know_how" onclick="location.reload();location.href='url_name'">Know More</a>

就像这样 _self window.open (" www.youraddress.com ", " ")

你需要使用name属性:

window.open("https://www.youraddress.com","_self")

编辑:Url前应加上协议。没有它尝试打开相对url。在Chrome 59, Firefox 54和IE 11中测试。
