我试图将数据从数据库提取到 Highcharts 极坐标图，当我尝试将其加载到浏览器上时，我在浏览器的检查器工具中收到此错误:
SyntaxError: missing } after property list on Line 78
这是我使用过的代码。
编辑:IVE 第一次输入不同的代码

$connection = mysqli_connect("localhost","root","","uwguru");

最佳答案
检查 while 循环的输出。
此外，请考虑构建数组并使用 json_encode() 将其输出为 JSON 。
请注意，您仍然需要在 JavaScript 端解析 JSON。如果你打算混合使用 javascript 和 PHP，通常最好单独输出 JS 数据(就像作为 JS 逻辑之上的变量)，然后在需要的地方解析它。这使得将来维护代码变得更加容易。
<?php
// put this in above the `$('#container').highcharts({` line
//and you can access it as a proper JS variable as you need to.
$sql="SELECT * FROM exercises";
$result= mysqli_query($connection,$sql);
$output = [];
while ($registros = mysqli_fetch_array($result)) {
$output[] = $registros['muscle_string'];
}
echo "var muscleString = JSON.parse('".json_encode($output)."');";
?>
也就是说，您收到的错误是您可能需要这个:
series: [{
name: 'Test',
data: [
["6","745","7547","4","5","1","2","634234","325235"]
]
pointPlacement: 'on'}
最终看起来像这样:
series: [{
name: 'Test',
data: [
["6","745","7547","4","5","1","2","634234","325235"]
], // <-- add comma here
pointPlacement: 'on'
}] // <-- close your array with a closing square bracket
