我正在使用 API highcharts 按国家/地区显示我网站的访问者数量。我通过 mysql 接收数据,我在 php 中有这个表:
<?php $data = Array ( [0] => Array ( [name] => DE [y] => 1 ) [1] => Array ( [name] => FR [y] => 3 ) [2] => Array ( [name] => US [y] => 1 ) [3] => Array ( [name] => XX [y] => 1 ) ); ?>
然后在我的 php 文件的底部,我放了我的 js:
var g_donnes = '<?php echo json_encode($data); ?>';
Highcharts.chart('container', {
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: 'Browser market shares in January, 2018'
},
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: [{
name: 'Brands',
colorByPoint: true,
data: g_donnes
}]
});
所以当我做一个console.log(g_donnes)时,我有这个表[{"name":"DE","y":1},{"name":"FR","y":3},{"name":"US","y":1},{"name":"XX","y":1}]
,但是在数据级别的代码没有处理g_donnes的缺点:g_donnes
