<script src="http://jquery-csv.googlecode.com/files/jquery.csv-0.71.js"></script>
    <script type="text/javascript">
      google.load("visualization", "1", {packages:["corechart"]});
      google.setOnLoadCallback(drawChart);

    function drawChart() {
       // grab the CSV
       $.get("Chart1-data.csv", function(csvString) {
          // transform the CSV string into a 2-dimensional array
          var arrayData = $.csv.toArrays(csvString, {onParseValue: $.csv.hooks.castToScalar});
        alert(arrayData);
          // this new DataTable object holds all the data
          var data = new google.visualization.arrayToDataTable(arrayData);

          // this view can select a subset of the data at a time
          var view = new google.visualization.DataView(data);
          view.setColumns([0,1]);

         // set chart options
         var options = {
        title: "A Chart from a CSV!",
        hAxis: {title: data.getColumnLabel(0), minValue: data.getColumnRange(0).min, maxValue: data.getColumnRange(0).max},
        vAxis: {title: data.getColumnLabel(1), minValue: data.getColumnRange(1).min, maxValue: data.getColumnRange(1).max},
        legend: 'none'
         };

        var chart = new google.visualization.PieChart(document.getElementById('piechart'));
        chart.draw(data, options);
});
      }

Error:

SyntaxError: missing ) after argument list

i.e. line where script ends

UPDATE: there was }); missing. Now no error but chart does not appear

回答1:

Your closing brackets for $.get( should be }); not just };

$.get({
 // code
});

And you're also missing a closing curly bracket to close your function.
