Syntax Required for If/Else Statement inside For Loop

I have a function that is applied onclick only when a specified variable is defined. Once that variable is defined, it loops through a set of nested arrays to produce a URL which the user is sent to. I added an else statement within the logic of the if statement so that if the condition is not met, the user is sent to a default URL which states, "sorry, no items found." However, since it is within a loop that is looping through items that don't match to find the one that does, it consistently applies the else statement before the loop finds the match.

Is there a better syntax to use?

function applyUrl() {

var locSelect = localStorage.getItem("loc");
var positSelect = localStorage.getItem("posit");
var userSelect = locSelect + " - " + positSelect;
if(localStorage.getItem("posit") != null){

        for (var i = 0; i < sortedArray.length; i++) {
        var stuff = sortedArray[i];
        for (var j = 0; j < stuff.length; j++) {
            if(stuff[j] === userSelect) {
                  window.location.href = stuff[1];
                }else{
                  window.location.href = 'default.html';
                }
            }

        }

    }
}
