Trouble outputting full list of numbers using innerHTML

Question

the following is code to create a sequential list of numbers from 1 to 10. I'd like to take this list and output in the div "pagination" using innerHTML. However, when I execute the script, the only thing that is outputted is the number 10. When I overwrite the page using document.write instead, it outputs the whole list. Can someone tell me what I'm doing wrong? Thanks.

function generateNumbers() {
    var numbers = new Array();

    // start generating numbers
    for(var i = 1; i <= 10; i+= 1) {
        numbers.push( i );
    }

    // print numbers out.
    for(var i = 0; i < numbers.length; i++) {
        document.getElementById("pagination").innerHTML = numbers[i] + "<br>";
    }
}

and in the HTML:

<div id="pagination"></div>

Answer 1

Well, you override innerHTML in every step.
Try:

document.getElementById("pagination").innerHTML += numbers[i] + "<br>";

Or better:

// no for loop
document.getElementById("pagination").innerHTML = numbers.join("<br>");

Answer 2

for(var i = 0; i < numbers.length; i++) {
    document.getElementById("pagination").innerHTML = numbers[i] + "<br>";
}

This replaces the innerHTML every single time through the loop, so you only see the last iteration.

Try making that = a +=.

Or even better, build it up in a string and set the innerHTML just once with that final string. This will be faster since it only has to parse the string as HTML once instead of 100 times.
