JavaScript: JavaScript：

function imageLader() {
    var imageLijst = ["../images/melk.png", "../images/wasmiddel.png", "../images/bike.png", "../images/holiday.png", "../images/lego-starwars.png",
        "../images/electrische-tandenborstel.png", "../images/my-little-pony.png", "../images/wii-u.png"];

    for(var i = 0; i <imageLijst.length; i++) {
         var imgDiv = document.getElementById("image_"+ i);
         var img = new Image();
         img.src = imageLijst [i];
         imgDiv.appendChild(img);
    }
}

window.onload = imageLader;

Answer 1

<script> src = "imageLoader.js"</script>

is invalid. 是无效的。 That should be 那应该是

<script src="imageLoader.js"></script>

instead. 代替。

Also, though not shown here, just assigning to window.onload is dangerous, as it may be overwritten. 另外，尽管未在此处显示，但仅将其分配给window.onload是危险的，因为它可能会被覆盖。

Answer 2

If you can, elaborate on how its not working. 如果可以，请详细说明其不起作用。 Is there an error (ie a JavaScript error) or is the behavior not as you expect (ie it appears to be doing nothing)? 是否有错误（即JavaScript错误）或行为是否不符合您的预期（即似乎无所事事）？

I would suspect that in this instance its not doing anything because of the following line. 我怀疑在这种情况下，由于以下原因，它什么也没做。

<script> src = "imageLoader.js"</script>

The "src" attribute needs to be defined as a part of the script tag. 需要将“ src”属性定义为脚本标签的一部分。 Trying changing it to this. 尝试将其更改为此。

<script type="text/javascript" src="imageLoader.js"></script>

Answer 3

You are missing lots of quotation marks in your html markup 您在html标记中缺少很多引号

Example: 例：

<div class=images id=image_0></div>

should be 应该

<div class="images" id="image_0"></div>

or 要么

<div class='images' id='image_0'></div>
