Question

Here is my code

<script type="text/javascript">

    var options = {
        chart: {
            renderTo: 'container'
        },
        title: {
            text: 'Money Conversion'
        },
        yAxis: {
            title: {
                text: 'Exchange Rate'
            }
        },
        xAxis: {
            type: 'datetime',
            dateTimeLabelFormat: {
            }
        },
        series: [{
            type: 'line',
            data: []
        }]
    };

    $(document).ready(function () {

        if (typeof options != 'undefined') {
            alert("options is undefined!");
        }
        else {
            alert("options is defined!");
        }

The alert I am getting is “options is undefined”. What am I doing wrong?

    if (typeof options != 'undefined') {
        alert("options is undefined!");
    }

You’re alerting ‘options is undefined’ when options is defined.
