Question

my js is not good, but I’m thinking I’m going to need to use the getElementbyId some think like:

if (a == ‘tick’)
document.getElementById(‘imageDiv’) = tick.gif
else
document.getElementById(‘imageDiv’) = cross.gif
<div id="imageDiv"></div>

but is does not work.

Answer 1

Use this, it should work.

<script type="text/javascript">
function image(thisImg) {
    var img = document.createElement("IMG");
    img.src = "images/"+thisImg;
    document.getElementById('imageDiv').appendChild(img);
}
if (a == 'tick') {
    image('tick.gif');
} else {
    image('cross.gif');
}
</script>
<div id="imageDiv"></div>
