How can I just call a js function from within an html file, with no event trigger? I want to have code like:

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script src="jquery.flot.js"></script>
<script src="chart.js"></script>

<title>
</title>
</head>

<body>

<div id="chart1" style="width:600px;height:300px"></div>

show_graph({{ chart_type }}, {{ data }}, {{ options }});

</body>

</html>

but this just results in the function call being printed to the screen, instead of the function actually being executed.

e.g. I’m getting
show_graph(bar, [[1, 2000], [2, 50], [3, 400], [4, 200], [5, 5000]], [‘Foo’]);

What do I do?

EDIT:

I appreciate the feedback, but I tried wrapping it in a script tag and got an “invalid number of parameters” error.

the javascript is:

function show_graph(charttype, data, options){

    var chart_options = {
        series: {
            charttype: {
                show: true
            }
        }
    }

    var plot = $.plot($("#chart1"), [data], [chart_options]);
}

so I suppose the real question is “why am I getting an “invalid number of parameters” error when I’m passing 3 parameters and accepting 3 parameters?”

    Wrap it in <script> tags:

    <body>

<div id="chart1" style="width:600px;height:300px"></div>

<script type="text/javascript">
    show_graph({{ chart_type }}, {{ data }}, {{ options }});
</script>

</body>

    …though I don’t know how the template factors in. I imagine it will render the same.
