Run script which opens a new tab and runs another script on it

[Crimson Dog]

Ok i signed up for to ask this. If you'd be so kind to answer i'd be much obliged.

So i'm trying to run a bookmark script which would:
1) fill in some forms
2) click the button in a new tab (ctrl-click on the button in chrome, for example)
3) run another script (or a part of the same script) on that new tab (since the button sends to a confirm screen)
4) close that tab
5) repeat that process with different values in the forms (this would be done with a "for" loop, counter and an array, i'd reckon).

currently i need to use a cookie as a counter and click the bookmark 50+ times

is this even possible? running a script on a different page/tab from another, i mean.

I hate bumping my own thread but i realized that i forgot to attach the code i was working with.

javascript: var villages = "556|668 548|845";
var villagearr = villages.split(" ");
var targets = 2;
 
 
function getCookie() {
    var i,
    x,
    y,
    ARRcookies = document.cookie.split(";");
    for (i = 0; i < ARRcookies.length; i++) {
        x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
        y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
        x = x.replace(/^\s+|\s+$/g, "");
        if (x == "villagenum") {
            return unescape(y);
        };
    }
};
 
function setCookie(x) {
        if(x == targets){
                x = 0;
                window.alert("Cycle complete, returning cookie to 0.");
        };
       
    document.cookie = "villagenum=" + x.toString();
};
 
/*this is for the form screen*/
if (document.URL.split('screen=place').length == 2 && document.URL.split('try=confirm').length != 2) {
    var curVil = getCookie();
    coordData = villagearr[curVil];
    getCoords = coordData.split("|");
    document.forms[0].elements[5].value = 5;
    document.forms[0].elements[4].value = 1;
    document.forms[0].elements[11].value = getCoords[0];
    document.forms[0].elements[12].value = getCoords[1];
    setCookie(parseInt(curVil) + 1);
    document.getElementById('target_attack').click();
   
};

/*this is for the confirm screen*/
if (document.URL.split('try=confi').length == 2) {
    document.getElementById('troop_confirm_go').click();
};
