This isn't totally necessary, I'm just trying to simplify my code. This is what I have:

   function fillWebsitePlaceFiller(number) {

     document.getElementById(placefillerWebsite + number).innerHTML = placefillerWebsite;

   }



            fillWebsitePlaceFiller(1);

            fillWebsitePlaceFiller(2);

            fillWebsitePlaceFiller(3);

            fillWebsitePlaceFiller(4);

            fillWebsitePlaceFiller(5);

            fillWebsitePlaceFiller(6);

            fillWebsitePlaceFiller(7);

Is there a way I can call the function just once, and it will run through it 7 times with each argument?

Method 1 - iteration

for (var i = 1; i < 8; i++) fillWebsitePlaceFilter(i);

Method 2 - recursion

(function repeat(number) {

    fillWebsitePlaceFiller(number);

    if (number > 1) repeat(number - 1);

})(7);

Method 3 - functor application

[1, 2, 3, 4, 5, 6, 7].forEach(fillWebsitePlaceFiller);

Method 4 - internal iteration

function fillWebsitePlaceFiller(times) {

    for (var number = 1; number <= times; number++) {

        document.getElementById("placefillerWebsite" + number).innerHTML = placefillerWebsite;

    }

}

Method 5 - extend function behaviour

Function.prototype.sequence = function(from, to) {

    for (var i = from; i <= to; i++) this.call(null, i);

};



fillWebsitePlaceFiller.sequence(1, 7);

Method 6 - XPath (warning: not tested)

var query = '//*[@id[starts-with(., "placefillerWebsite"]]';

var result = document.evaluate(query, document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null);

while (var node = result.iterateNext()) node.innerHTML = placefillerWebsite;

Method 7 - jQuery

$('[id^="placefillerWebsite"]').html(placefillerWebsite)

I recommend one of the methods where you don't assume there are always seven of them.
