Question

我是JS / AJAX / JSON的新手，我想将ajax应用于我的代码，以便我的图表可以重绘，这取决于数据在数据库中的获取。这行代码没有错误，但没有自己刷新。请帮我把这个图表动态化。帮助/意见/建议表示赞赏。

这是我的代码： data.php

$<?php
$con = mysql_connect("localhost","root","");

if (!$con) {
die('Could not connect: ' . mysql_error());
}

mysql_select_db("survey_processor", $con);

$result = mysql_query("select msv_variants.var_text, B.Count from msv_variants, (SELECT           ans_var_id ,count(*) AS Count FROM (select ans_var_id from msv_answers where ans_que_id = '11') as A group by ans_var_id) AS B where msv_variants.var_opt_id = B.ans_var_id AND msv_variants.var_que_id = '11' ");

$rows = array();
while($r = mysql_fetch_array($result)) {
$row[0] = $r[0];
$row[1] = $r[1];
array_push($rows,$row);
}

print json_encode($rows, JSON_NUMERIC_CHECK);

mysql_close($con);
?>

pie.js

    $(document).ready(function() {
        var options = {
            chart: {
                renderTo: 'container',
                plotBackgroundColor: null,
                plotBorderWidth: null,
                plotShadow: false
            },
            title: {
                text: 'Web Sales & Marketing Efforts'
            },
            tooltip: {
                formatter: function() {
                    return '<b>'+ this.point.name +'</b>: '+ this.percentage +' %';
                }
            },
            plotOptions: {
                pie: {
                    allowPointSelect: true,
                    cursor: 'pointer',
                    dataLabels: {
                        enabled: true,
                        color: '#000000',
                        connectorColor: '#000000',
                        formatter: function() {
                            return '<b>'+ this.point.name +'</b>: '+ this.percentage +' %';
                        }
                    }
                }
            },
            series: [{
                type: 'pie',
                name: 'Browser share',
                data: []
            }]
        }

        $.getJSON("data.php", function(json) {
            options.series[0].data = json;
            chart = new Highcharts.Chart(options);
        });



    });

请帮助我完成我的项目。三江源

您需要更新该图表中的数据，例如：

$(document).ready(function() {
    var options = {
        chart: {
            renderTo: 'container',
            plotBackgroundColor: null,
            plotBorderWidth: null,
            plotShadow: false,
            // add code below:
            events: {
                load: function() {
                     var series = this.series[0];
                     setTimeout(function() {
                         $.getJSON("data.php", function(json) {
                             series.setData(json);
                         });
                     }
                }
            }
        },
        //rest of options and code
    };
});
