Javascript to reload a new tab page

window.open("http://google.com", '_blank');
var childWindow = "http://google.com";
childWindow.location.href = "http://google.com";
I have an eventAddListener that loads http://google.com on a new tab with a button press, but right after it opens the new tab of google.com, I want it to REFRESH again. NOT my base page but the NEW tab page, by itself. The code I showed is just one of the examples out of 5 pages worth of google search which don't work.
UPDATE:
var win = window.open('google.com', 'New Window'); setTimeout(function () { var win = window.open('google.com', 'New Window'); },3000);
This is the best i could come up with. It opens new tab and "Reloads" the new tab rather than refresh it.
What I want is for example, you click on new tab, you paste a link then press enter, which EXECUTES the link. I basically want a javascript function which EXECUTES the link.

You can't do this.
In order to trigger a reload in the new tab/window you need to run JS in that tab/window.
The same origin policy prevents this.
If you had control over the new page then you could have an event listener running in it and post a message asking that listener to trigger a refresh.
Obviously you can't do that with Google's page.
This question, however, reads like an XY problem. If the goal is to display fresh (and not old, cached, out of date) information and the target page is not a third party one then you shouldn't be using JS to hack your way around caching. Instead set better caching rules on the target page in the first place.

I worked on something similar in the past few weeks and the code below worked for me.
index.html
<button onclick="openTab()">New Tab</button>
<script>
function openTab(){
//this opens a new tab while creating a variable name for that tab
var newTab = window.open("https://google.com","_blank");
//this refreshes that new tab
newTab.location.reload();
}
</script>
Just to prove that this works on the new tab I used the code
<script>
function openTab(){
//this opens a new tab while creating a variable name for that tab
var newTab = window.open("https://google.com","_blank");
//this will alert in the new tab
newTab.alert("New Tab");
//before the following reload code takes effect
//this refreshes that new tab
newTab.location.reload();
}
</script>
Hopefully that's what you are looking for.

From my understanding you want the new tab to refresh once opened with JavaScript instead of the current tab where you run the JavaScript code from.
That's not directly possible. The JavaScript code will only run for the tab it was executed in. The newly opened tab does not know that JavaScript code should be running. The current tab cannot pass over instructions for the new tab to execute.
However, you can select the newly opened tab manually first and then execute Javascript code to refresh the page. But that probably defeats the purpose of what you're trying to do.

closing browser within chrome page on test complete

So using TestComplete I'm essentially trying to open up a session on chrome, navigate to a web page, and then click a button on that page. after I'm finished I want to close that browser page. I'm having trouble closing the page though. Here is the code I have so far.
function ChromeTest
{
Browsers.Item(btChrome).Run(MyWebAdress);
var browser = Sys.Browser("chrome");
var page = Sys.Browser("chrome").Page(MyWebAdress);
var MyButton = page.ButtonLocation;
MyButton.click();
browser.BrowserWindow.Close(5000);
}
however, at the Close line I get an error that says "Unable to find the object BrowserWindow". Thanks in advance for any help you have.

Change BrowserWindow to BrowserWindow(0) (or whatever index you see in the Object Browser):
browser.BrowserWindow(0).Close(5000);
Or you can call Close() directly on the Chrome process:
browser.Close(5000);

Lotus Notes Xpage - view.postScript("window.open()") doesn't open a new window after replacing the contained Pagename (only at a specific document)

i'm currently working on a function (started after Buttonclick) to print a document in Lotus Notes (IBM Domino Designer 9.0 Social Edition Release 9.0). I have a custom control which creates a new document to the database. After saving the document its opened in read-only-Mode. There you have a button which will redirect you to a new window where the same contents are displayed without any layouts and something else (just the Text). Now its possible to print the page with Ctrl+P. There are two differen xPages for that.
Distribution.xsp
DistributionPrint.xsp
First of all i'm using
path = facesContext.getExternalContext().getRequest().getRequestURL();
to get the current page URL. After that there is an option to replace the current Page of the path (Distribution.xsp) into DistributionPrint.xsp.
var replacePage = #RightBack(path, "/");
path = #ReplaceSubstring(path, replacePage, "DistributionPrint.xsp");
When im testing it the replacement successfully worked. After that i'm bulding a new URL for the specific document to open with the new path. Finally everything is placed into the view.postScript method:
var docid = docApplication.getDocument().getUniversalID();
view.postScript("window.open('"+path.toString() + "?documentId=" + docid + "&action=openDocument"+"')")
Now my Problem starts. At 99% of my trys the new window is opened like i said the programm to do. But there are some kind of documents where i click on the button and he doesn't open a new window and trys to open the old Distribution.xsp url. I already tested out the path he wants to open at these kind of documents by using the debugtoolbar. The result of the button click returns the completly correct URL which should be opened. I can also copy that url and paste it manually into my browser => it works! But if i want to open that URL by a buttonclick and viewPostScript nothing happens.
Has anybody expierenced the same problem like me? Maybe one of you can help me through that problem. Its really annoying that everything works finde at 99% of my documents but at some documents it doesn't work although the given url is 100 percent correct.
Thanks for everyones help!

Try adding you code into a javascript function on the page and call that function from your view.postscript code
Or as Panu suggested add it to onCompete code

If the URL is correct then it sounds like a problem with view.postScript. Try with <xp:this.onComplete>.
Other things to try:
Use var w = window.open(... Plain window.open may change the URL of
current window.
Double check the URL with an alert();

You might be barking up the completely wrong tree. Did you try, instead of creating a second page for printing, create a second CSS stylesheet?
Using #Media Print you can tell the browser to use that stylesheet for printing. There you set all navigational elements to display : none and they won't print.
Removes the need to maintain a separate XPage for the printing stuff.

Thank you everyone for your suggestions. The solution of Fredrik Norling worked for me. I placed the Code into a function and called it at the buttonclick. Now every page is opened as expected. Thank you very much for the help!

Safari extension, open new tab with HTML page, pass parameters

In my extension I want to open a new tab when a toolbar button is clicked (works), display a static HTML page with JavaScript on the tab (works) and pass data (URL from the originating page) to the new tab (does not work). I tried:
Using query parameters like myTab.url = safari.extension.baseURI + 'page.html?' + params, but the target page does not seem to have a location assigned (location.search giving no result).
myTab.page.dispatchMessage("url", "someUrl"); after opening the tab, but the message never arrives in the new tab (I suspect, it's already "through", when the tab has opened).
Any suggestions?

I parsed document.URL in opened page for specific parameter and it worked for me. E.g.
function __onLoad()
{
var p = $.url(document.URL);
alert(p.param("url"));
}
And two possible reasons for missed message:
You did not add message event listener on your page
You called dispatchMessage before event listener was added

Google Chrome opens window.open(someurl) just fine...but page/window with clicked link also opens someurl.com

As the title says "Google Chrome opens window.open(someurl) just fine...but page/window with clicked link also opens someurl.com.
When I click the "Click here" link with the onclick="shpop..." call attached, my pop up opens /facebook_login.php' correctly...BUT...at the same time, the original window opens /facebook_login.php too!
This happens in Chrome and IE, but FF is fine and doing just what i want..
I have this link:
Click here
I know I could remove the href="/facebook_login.php" and replace with href="#" .. but I need the link to work if js is disabled.
I have this js code imported in my tag:
function shpop(u,t,w,v)
{
var text = encodeURI(t);
var uri = encodeURI(u);
var h = document.location.href;
h = encodeURI(h);
var wwidth='600'; /*popup window width*/
var wheight='300'; /*popup window height*/
if(v=='' || undefined==v)v=document.domain; /*popup name/title */
switch(w){
case 'loginfb':
var url = '/facebook_login.php';
wwidth='980';
wheight='600';
break;
}
window.open(url,v,'width='+wwidth+',height='+wheight);
return false
}
Any ideas?

what is with returning false, and having false in the onclick?
This
onclick="shpop('','','loginfb','');return false"
Just needs to be
onclick="return shpop('','','loginfb','');"
If the onclick returns any error, the link will still open up. Do you see any errors in the JavaScript console? I wonder if the browsers are freaking out about any . in the window name from using document.domain. Try giving it a name.
onclick="return shpop('','','loginfb','foobar');"

According to the latest browser statistics - well last time it was measured anyway (2008) only 5% of users had Javascript disabled. Nowadays it's likely to be less. Consider that all browsers have it enabled by default. Therefore it's generally only advanced users that for whatever reason choose to disable javascript, and will therefore understand that there's a good chance any website they visit won't work as expected - Facebook, Google, Amazon - everyone uses javascript these days. It's perfectly acceptable to assume the user is using it, with one overall <noscript> version at the start of your page for those users if you really really want to cover all your bases :)

Here is the simplest solution:
<a href="/facebook_login.php"
target="FBpopup"
onclick="window.open('about:blank','FBpopup','width=980,height=600')">
Click here
</a>
You don't need return false because you actually want the link to execute.
The trick is to use the same window name in both the window.open and in the link target.
window.open will create the popup, then your login page will run in that popup.
If popups are blocked or Javascript is disabled, your login page will run in a new tab.
