我的问题是:我正在使用jquery的 $.post
方法。出于某种原因, data
似乎没有定义。
让我解释一下我的代码是如何构造的。。。
1.我有以下带有onclick功能的按钮:
$data->acción = "<div class='text-center'><div class='btn-group'><button id='modificar_$data->id' class='btn btn-primary btn-sm btnEditar' value='edit'><i class='material-icons'>edit</i></button><button id='deleteID_$data->id' onclick='Delete($data->id, $tableName, $idName)' class='btn btn-danger btn-sm btnBorrar'><i class='material-icons' value='delete'>delete</i></button></div></div>";
相同的代码缩进以提高可读性:
$data->acción = "
<div class='text-center'>
<div class='btn-group'>
<button
id='modificar_$data->id'
class='btn btn-primary btn-sm btnEditar'
value='edit'
>
<i class='material-icons'>edit</i>
</button>
<button
id='deleteID_$data->id'
onclick='Delete($data->id, $tableName, $idName)'
class='btn btn-danger btn-sm btnBorrar'
>
<i class='material-icons' value='delete'>delete</i>
</button>
</div>
</div>
";
2.我的 Delete()
功能:
function Delete(id, tableName, idName) {
if (confirm("¿Estás seguro que deseas borrar el registro con ID " + id + "?") == true) {
console.log("First parameter: " + id + "\nSecond parameter: " + tableName + "\nThird parameter: " + idName); // I GET MY FUNCTION PARAMETERS.
console.log("<?=SITE_URL_ADMIN?>/alexcrudgenerator/crud/res/?action=deleteRegistro&tabla=" + tableName + "&nombre_campo=" + idName + "&id=" + id); // I GENERATE MY POST URL CORRECTLY.
$.post("<?=SITE_URL_ADMIN?>/alexcrudgenerator/crud/res/?action=deleteRegistro&tabla=" + tableName + "&nombre_campo=" + idName + "&id=" + id, function(data) {
console.log("My data: " + data);
if(data == 1) {
console.log("Data OK");
//$().hide();
}
else if (data == '') {
console.log("Data empty");
}
else if (data == null) {
console.log("Data null");
}
else if (data) {
console.log("Data exist");
}
else {
console.log("Other reasons");
}
});
}
}
3.这样你就可以看到 console.log()
返回:
为什么 data
没有定义?
编辑:这是我的完整代码:(我不想上传完整代码以免造成混乱,我试图最小化并压缩它)。

如果您想要恢复数据,请使用
$.get
```$.get("/alexcrudgenerator/crud/res/?action=deleteRegistro&tabla=" + tableName + "&nombre_campo=" + idName + "&id=" + id, function(result){
console.log(result);
});

您在函数delete()中提供的url完全错误,
此url适用于get方法not post,用于发布任何不需要将数据放入url的内容。
这是
function(data, status)
用于在何处处理错误data
是来自url和status
是发送到url的数据的状态。你必须小心给出条件
if(data == 1)
哪里data
是来自url的响应,因此它不是布尔值。在数据发布的另一方面处理请求是非常重要的,所以请检查一次。
