Question

I am setting up the following code to allow me decide which JS functions/files to run based on conditional PHP echos to the array given. For some reason I seem unable to retrieve the contents of the array in the Javascript code given:

HTML

<!-- add functions to run at window.onload here -->
<script type="text/javascript">
on_multiload [0] = "message";
on_multiload [1] = "message2";

</script>

<script type="text/javascript" src="http://www.ondesign.org.uk/wp-content/plugins/on-dev-kit/js/pageload.js"></script>

JS

window.onload = function () {
    on_multiFunction_load (on_multiload);
}

function on_multiFunction_load (on_multiload) {
    for (var i = 0; i< on_multiload.length; i++) {
        alert (on_multiload[i]);
    }
}

Can anyone see what I’ve done wrong (first time loading js variables from an external source, so it’s likely to be simple)?

Answer 1

You are trying to assign values to properties of on_multiload while on_multiload is undefined.

var on_multiload = [];
on_multiload[0] = "message";
on_multiload[1] = "message2";

or

var on_multiload = [ "message", "message2" ];
