我正在从服务器获取正确的 JSON 对象数组并将其分配给系列。 chart_cfd.series 还在调试器中显示了正确的对象，但没有绘制图表。
这可能是什么问题？我需要更改数组成员的类型吗？
注意:如果我在本地使用 javascript 提供系列数据，图表会完美填充(简单的列类型)
Javascript:(我正在使用 highcharts 框架)
//图表对象中的series = []
function requestCFDStatusData(){
$.post(
'ajax/cfdUtil/cfd_status.php',
function(response){
chart_cfd.series = response;
});
}
PHP代码
<?php
header("Content-type: text/json");
$cfdData = array(
array(
'name' => 'A',
'data' => array(49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4,22,34,23,11)),
array(
'name' => 'B',
'data' => array(83.6, 78.8, 98.5, 93.4, 106.0, 84.5, 105.0, 104.3, 91.2, 83.5, 106.6, 92.3,22,50,34,11)),
array(
'name' => 'C',
'data' => array(48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2,100,25,45,42)),
array(
'name' => 'D',
'data' => array(42.4, 33.2, 34.5, 39.7, 52.6, 75.5, 57.4, 60.4, 47.6, 39.1, 46.8, 51.1,32,33,46,54)),
array(
'name' => 'E',
'data' => array(48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2,12,12,44,50)),
array(
'name' => 'F',
'data' => array(48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2,12,12,44,50)),
array(
'name' => 'G',
'data' => array(48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2,12,12,44,50)),
array(
'name' => 'H',
'data' => array(48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2,12,12,44,50)),
array(
'name' => 'I',
'data' => array(48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2,12,12,44,50)),
array(
'name' => 'J',
'data' => array(48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2,12,12,44,50)),
array(
'name' => 'K',
'data' => array(48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2,12,12,44,50))
);
$jsonEncoded = json_encode($cfdData);
echo $jsonEncoded;
?>
注意:如果我在本地使用 javascript 提供以下数据，则可以正常工作
series: [{
name: 'A',
data: [49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4,22,34,23,11]

最佳答案
在标题中使用 content-type 作为 javascript
header("Content-type: text/javascript");
然后使用jquery的getJSON方法作为
$.getJSON('ajax/cfdUtil/cfd_status.php',function(response){
chart_cfd.series = response;
});
