How do I get a nested anonymous function to open links in a new window

How do I make this Javascript to open on a new page when
I’ve created an allSelect variable referencing all select elements nested within the govLinks form (it works but opens on the same window).

Within the nested anonymous function, I need to retrieve tge value of the property of evt.target and store it in the linkURL variable

Within the nested anonymous function I also need to use the window.open() method to open a new browser or any window options. Store the window under the newWin variable.

Any help will be appreciated.

Here is my current Javascript code.

// Function invoked when window is loaded, and it is an anonymous function

window.onload = function() {

// Get all select elements in 'govlinks'

var allSelect = document.getElementById("govLinks").querySelectorAll("select");


// Loop on all the select elements and attach an event to them

for (var i = 0; i < allSelect.length; i++) {

allSelect[i].onchange = function (evt) {

console.log(evt.target.value);

location.href = evt.target.value; // Update location href
}

}

}
