简介

我正在使用json，ajax和php进行datatables.net jquery服务器端处理。我可以单击行按钮，然后从数据库中删除该行。但是，该页面永远不会使用ajax.reload();刷新页面。

问题

此代码：

console.log("success function data reached");

似乎永远无法达到。是什么原因造成的？

我没有错误，并且该表正确地从数据库中删除了，这就是我被卡住的原因。 datatables.net上的所有内容似乎都很好，我很可能遇到了php问题？

Index.php

$(document).on('click','.delete_btn',function (){

var id = $(this).attr("id").match(/\d+/)[0];

var del_id = $('#example').DataTable().row( id ).data();

var del_id = del_id[0];

console.log(del_id[0]);

$.ajax({

type:'POST',

url:'delete.php',

dataType: 'json', //This says I'm expecting a response that is json encoded.

cache: false,

data: { 'del_id' : del_id},

success: function(data){

console.log("success function data reached");

if(data=='result_ok'){ //You are checking for true/false

//document.location.reload(true);

alert(data);

table.ajax.reload();

}else{

console.log('The row was not deleted.');

}

}

});

});

delete.php

$del_id = $_POST['del_id'];

$stmt = $conn->prepare("DELETE FROM employees WHERE id = ?");

$stmt->bind_param('i', $del_id);

$confirmDelete = $stmt->execute();

//header("location: index.php");

if($confirmDelete){ //Check to see if there was an affected row.

echo "result_ok";

}

echo json_encode($confirmDelete);

?>
