Using javascript, I want to open a new page in a different tab, but remain focused on the current tab. I know I can do it like this:

open(\'http://example.co

    UPDATE: By version 41 of Google Chrome, initMouseEvent seemed to have a changed behavior.

    this can be done by simulating ctrl + click (or any other key/event combinations that open a background tab) on a dynamically generated a element with its href attribute set to the desired url

    In action: fiddle

    function openNewBackgroundTab(){
    var a = document.createElement("a");
    a.href = "http://www.google.com/";
    var evt = document.createEvent("MouseEvents");
    //the tenth parameter of initMouseEvent sets ctrl key
    evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0,
                                true, false, false, false, 0, null);
    a.dispatchEvent(evt);
}

    tested only on chrome

    THX for this question! Works good for me on all popular browsers:

    function openNewBackgroundTab(){
    var a = document.createElement("a");
    a.href = window.location.pathname;
    var evt = document.createEvent("MouseEvents");
    //the tenth parameter of initMouseEvent sets ctrl key
    evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0,
                                true, false, false, false, 0, null);
    a.dispatchEvent(evt);
}

var is_chrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1;
if(!is_chrome)
{
    var url = window.location.pathname;
    var win = window.open(url, '_blank');
} else {
    openNewBackgroundTab();
}

    As far as I remember, this is controlled by browser settings. In other words: user can chose whether they would like to open new tab in the background or foreground. Also they can chose whether new popup should open in new tab or just... popup.

    For example in firefox preferences:

    Firefox setup example

    Notice the last option.

    Here is a complete example for navigating valid URL on a new tab with focused.

    HTML:

    <div class="panel">
  <p>
    Enter Url: 
    <input type="text" id="txturl" name="txturl" size="30" class="weburl" />
    &nbsp;&nbsp;    
    <input type="button" id="btnopen"  value="Open Url in New Tab" onclick="openURL();"/>
  </p>
</div>

    CSS:

    .panel{
  font-size:14px;
}
.panel input{
  border:1px solid #333;
}

    JAVASCRIPT:

    function isValidURL(url) {
    var RegExp = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/;

    if (RegExp.test(url)) {
        return true;
    } else {
        return false;
    }
}

function openURL() {
    var url = document.getElementById("txturl").value.trim();
    if (isValidURL(url)) {
        var myWindow = window.open(url, '_blank');
        myWindow.focus();
        document.getElementById("txturl").value = '';
    } else {
        alert("Please enter valid URL..!");
        return false;
    }
}

    I have also created a bin with the solution on http://codebins.com/codes/home/4ldqpbw

    I did exactly what you're looking for in a very simple way. It is perfectly smooth in Google Chrome and Opera, and almost perfect in Firefox and Safari. Not tested in IE.

    function newTab(url)
{
    var tab=window.open("");
    tab.document.write("<!DOCTYPE html><html>"+document.getElementsByTagName("html")[0].innerHTML+"</html>");
    tab.document.close();
    window.location.href=url;
}

    Fiddle : http://jsfiddle.net/tFCnA/show/

    Explanations:
    Let's say there is windows A1 and B1 and websites A2 and B2.
    Instead of opening B2 in B1 and then return to A1, I open B2 in A1 and re-open A2 in B1.
    (Another thing that makes it work is that I don't make the user re-download A2, see line 4)

    The only thing you may doesn't like is that the new tab opens before the main page.
