将数据从 $ajax 调用传递到 highcharts

Question

我有一个 ajax 电话

$(function () {
    $.ajax({
        url: '../../getdaily.php',
        type:'POST',
        dataType: '',
        success: function(output_string){
           console.log(output_string);
        },
        error: function (xhr, ajaxOptions, thrownError){
            console.log(xhr.statusText);
            console.log(thrownError);
        }
    });
});

并且 console.log 将输出...

[{"name":"Test-Cases","y":118},{"name":"White-Box","y":43},{"name":"Priority","y":44}]

我可以轻松地将其粘贴到我的 data : 图表中，并获得我正在寻找的饼图

...
series: [{
        type: 'pie',
        name: 'Browser share',
        data: [{"name":"Test-Cases","y":118},{"name":"White-Box","y":43},{"name":"Priority","y":44}]
    }]
...

我的问题是如何让 output_string 进入 Highcharts data : <here>。我已经尝试了各种方法将其作为变量传入并开始对此进行分拆，不知道为什么。

我用于 highcharts 并传入 id 的实际代码...

$('#container').highcharts({
    chart: {
        plotBackgroundColor: null,
        plotBorderWidth: null,
        plotShadow: false
    },
    title: {
        text: 'Browser market shares at a specific website, 2014'
    },
    tooltip: {
        pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
    },
    plotOptions: {
        pie: {
            allowPointSelect: true,
            cursor: 'pointer',
            dataLabels: {
                enabled: true,
                format: '<b>{point.name}</b>: {point.percentage:.1f} %',
                style: {
                    color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
                }
            }
        }
    },
    series: [{
        type: 'pie',
        name: 'Browser share',
        data: [{"name":"Test-Cases","y":118},{"name":"White-Box","y":43},{"name":"Priority","y":44}]
    }]
});

为了覆盖php文件，这里是结尾的一部分

...
$mysqli->real_query("SELECT priority FROM daily");
$rows2 = array();
$numb2 = 0;
$res2 = $mysqli->use_result();
$rows2['name'] = 'Priority';
while($r2 = $res2->fetch_assoc()) {
   $numb2+= $r2['priority'];
   $rows2['y'] = $numb2;
}

$result = array();
array_push($result,$rows);
array_push($result,$rows1);
array_push($result,$rows2);

echo json_encode($result);

只需将您的 highcharts 包装在一个函数中，将 ajax 响应作为函数的参数传递并将数据（在参数中）加载到您的 high charts，如：

function my_chart(response) {
    $('#container').highcharts({
        ...
        ...
        series: [{
            type: 'pie',
            name: 'Browser share',
            data: response
        }]
    });
}

并在 ajax 响应中调用您的函数，如：

    $(function () {
        $.ajax({
            url: '../../getdaily.php',
            type:'POST',
            dataType: '',
            success: function(output_string){
               //call my_chart function
               var parsed_response = jQuery.parseJSON(output_string);
               my_chart(parsed_response);
            },
            error: function (xhr, ajaxOptions, thrownError){
                console.log(xhr.statusText);
                console.log(thrownError);
            }
    });
});
