我的问题:我不知道为什么,我的朋友 switch
案例不能正常工作,我不知道为什么如果我的ajax status == 'succcess'
.
我的onclick功能在我的按钮中:
$data->acción = "<div class='text-center'><div class='btn-group'><button id='modificar_$data->id' class='btn btn-primary btn-sm btnEditar' value='edit'><i class='material-icons'>edit</i></button><button onclick='Delete($data->id, $tableName, $field)' class='btn btn-danger btn-sm btnBorrar'><i class='material-icons' value='delete'>delete</i></button></div></div>";
我的职能:
function Delete(id, tableName, field){
if (confirm("¿Estás seguro que deseas borrar el registro con ID " + id + "?") == true) {
$.post("<?=SITE_URL_ADMIN?>/alexcrudgenerator/crud/res/", {
action: "deleteRegistro",
id: id,
tableName: tableName,
field: field
}, function (data, status){
if (status === 'error') {
console.log("Not deleted");
}
else if (status === 'success') {
console.log("Deleted successfully");
}
});
}
}
我的开关盒:
switch($_POST['action']){
case 'deleteRegistro':
$id = $_POST['id'];
$tableName = $_POST['tableName'];
$field = $_POST['field'];
echo "Hello!";
?>
<script>alert("Hello!");</script>
<?php
break;
}
如您所见,我的ajax status == 'succcess'
:
如果您需要检查,这是我的完整代码:
<?php
use GuzzleHttp\json_decode;
include_once(DIR_PLUGINS.'/alexcrudgenerator/main.php');
$test = new GenerateCrud($_POST['tableName'], $_POST['id'], $_POST['tableFields']);
if ($_GET['action']){
print_a($_GET['action']);
}
switch($_POST['action']){
case 'datosTabla': // OK.
//print_r($_POST['action']);
$res = json_decode($_POST['datos']);
echo json_encode($res, JSON_UNESCAPED_UNICODE);
break;
case 'deleteRegistro':
$id = $_POST['id']; // Quiero obtener estas variables que he enviado desde la función Delete();
$tableName = $_POST['tableName']; // Quiero obtener estas variables que he enviado desde la función Delete();
$field = $_POST['field']; // Quiero obtener estas variables que he enviado desde la función Delete();
echo "Hello!";
?>
<script>alert("Hello!");</script>
<?php
break;
case 'showtable': // OK.
$res = getEntireTable($_POST['tableName'], $_POST['id'], $_POST['tableFields']);
$tableName = $_POST['tableName'];
$tableName = json_encode($tableName);
$field = json_decode($_POST['tableFields'],1)[0];
//print_r($tableName);
//print_r('<br>');
//print_r($campo);
foreach ($res as $data){
$data->acción = "<div class='text-center'><div class='btn-group'><button id='modificar_$data->id' class='btn btn-primary btn-sm btnEditar' value='edit'><i class='material-icons'>edit</i></button><button onclick='Delete($data->id, $tableName, $field)' class='btn btn-danger btn-sm btnBorrar'><i class='material-icons' value='delete'>delete</i></button></div></div>";
$resultados['data'][] = $data;
}
$resultados = json_encode($resultados); // 7 PROPIEDADES
foreach(json_decode($_POST['tableFields']) as $columnsDB){
$fields[] = array('data'=>$columnsDB);
}
$fields[]['data'] = 'acción';
$fields = json_encode($fields);
?>

有人能帮我一下吗?我真的不明白。
如果 status == 'success'
,这意味着post请求已成功发送,因此我应该进入我的 case switch
然后打印一个“你好!”。
我做错了什么?

你在问题中没有提到
switch
案件正在审理中,我想它已经开始了<?=SITE_URL_ADMIN?>/alexcrudgenerator/crud/res/"
index.php文件是否正常?因此,您使用ajax将数据发布到php文件中,ajax成功地发布了数据,但是您怎么会期望这样呢
hello
要在屏幕上显示吗?正如我在前面的回答中提到的,存在switch case的php文件的输出将不会显示,
$.post
方法只是将数据发布到文件,而不会重定向到该文件。出于您的需要,我建议您使用隐藏表单将数据发布到文件中。
修改后的删除函数将为。。
现在添加一个表单
deleteform
在html代码中注意:-在将此脚本用于函数之前添加Delete()
```
