解决方案

https：// www .google.com / search？q = sql + php [ ^ ]。

您的客户端脚本无法直接访问数据库。最接近的是通过Ajax调用，但它仍然必须通过像php这样的服务器辅助脚本，它依次处理数据库操作。

Ajax示例[ ^ ]

<?php
include 'connections.php';//db 
?>
<button type="button" class="btn btn-primary btn-sm" onclick="myFunction()" id="reqst">Submit</button>

<script>
function myFunction(){
// include connections.php file
// need to perform sql operations like select,insert etc.

}
</script>
<?php
}

?>

after submit need to perform sql operations in javascript. Is there anyway to do this? please anyone help me

解决方案

You client-side script has no access to the database directly. The closest is via Ajax call, but it still has to go through a server-aide script like php which in turns handles the database operation.
