Question

我有以下JSP：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

<%@ page import="org.json.JSONObject"%>
<%@ page import="org.json.JSONArray"%>
<html>
<head>
<script src="https://code.highcharts.com/stock/highstock.js"></script>
<script src="https://code.highcharts.com/stock/modules/exporting.js"></script>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Welcome <%=request.getAttribute("resultset")%></title>
</head>
<body>
    <h3>Login successful!!!</h3>
    <h4>
        Hello,
        <%=request.getAttribute("jsondata")%> 
    </h4>
    <p>------------</p>

<div id="container" style="height: 400px; min-width: 310px"></div>

<script type="text/javascript">
$(document).ready(function() {
    var data = <%=request.getAttribute("jsondata")%>;
    document.write($.parseJSON(data));
    var seriesOptions = [];

        // Populate series
        for (i = 0; i < data.DeltaRealTime.length; i++){
            seriesOptions[i] = {
                name: data.DeltaRealTime[i].name,
                data: [data.DeltaRealTime[i].key, parseFloat(data.DeltaRealTime[i].value)]
            };
        }

        $('#container').highcharts({
            chart: {
                type: 'spline',
                animation: Highcharts.svg, // don't animate in old IE
                marginRight: 10,

                events: {
                    load: function() {

                        // set up the updating of the chart each second
                        setInterval(function() {

                                // Populate series
                                for (i = 0; i < data.DeltaRealTime.length; i++){
                                    var chart = $('#container').highcharts();
                                    chart.series[i].addPoint([data.DeltaRealTime[i].key, parseFloat(data.DeltaRealTime[i].value)]);
                                }
                        }, 1000);
                    }
                }
            },
            title: {
                text: "Valori Delta"
            },
            xAxis: {
            [...]
            series: seriesOptions
        });
    });
</script>
</body>
</html>

但是当我运行我的应用程序时，只有“Hello”，并且打印了JSON值和虚线“---”。 JavaScript只是原始转移到HTML代码中：/

如果我改变

document.write($.parseJSON(data));

到

document.write(data);

输出HTML文档只是：

[object Object]

JavaScript没有在JSP中呈现
