我是编程新手我正在使用GetOrgChart处理动态组织层次结构图。我想删除java脚本函数中的硬代码值并将我的mysql查询结果数据传递给javascript函数我通过查询从数据库中获取数据并将其转换为json格式以在javascript函数中显示。
这是我的代码：
<?php
require ('db.php');
$selectSql = "SELECT
emp.id, emp.employee_parent_id, emp.emp_name,
emp.email,hd.desg_name
FROM
hr_employees emp
LEFT JOIN
hr_employees_designations empd ON emp.id = empd.id
LEFT JOIN
hr_designations hd ON empd.id = hd.id";
$result = mysqli_query($conn, $selectSql);
$arrAssociate = [];
while ($value = mysqli_fetch_assoc($result))
{
$json_array = json_encode($value);
echo $json_array;
//echo '<pre>', print_r($value, 1) , '</pre>';
}
?>

看看这个。
使用Laravel（刀片）：
let json = JSON.parse('@json($your_array_here)');
没有框架（您的情况）：
let json = JSON.parse('<?=json_encode($your_array_here)?>');
当您在PHP中拥有一个数组并且需要在JS中使用它时，有两种实现方式：
但是请注意您的浏览器控制台（Chrome，Firefox），如果您的JSON格式错误，则会警告您。
看看JSON.parse和JSON.stringify，了解此功能也很重要。
不要忘记声明的开头和结尾的'，就像我在下面的示例中所做的那样。
希望对您有帮助。
祝你有美好的一天。
