嗨,我正在尝试从数据表中删除我的记录,而无需在代码点火器中刷新页面,我使用了 ajax,我不知道我在哪里犯了错误,它没有删除记录
以下是我的观点:
<tbody>
<?php
if (!empty($employees)) {
foreach ($employees as $emp) {
?>
<tr>
<td><?php echo $emp->emp_name; ?></td>
<td><?php echo $emp->salary; ?></td>
<td class='text-center'>
<button type="submit" class="btn btn-info btn-xs confirmation" name="login"><i class='fas fa-edit'></i></button>
</td>
<td class='text-center'>
<button type="submit" onClick="return ConfirmDelete()" class="btn btn-danger btn-xs confirmation empdelete" id="<?php echo $emp->id;?>"><i class='fas fa-times'></i></button>
</td>
</tr>
<?php
}
}
?>
</tbody>
<script>
$(document).ready(function(){
$(".empdelete").click(function(e){
alert();
e.preventDefault();
$.ajax({
alert();
type: "POST",
url: "<?=site_url('Employee/delete');?>",
cache: false,
data: {id:$(this).attr("id")}, // since, you need to delete post of particular id
success: function(data) {
if (data){
alert("Success");
} else {
alert("ERROR");
}
return false;
}
});
});
});
</script>
这是我的控制器:
function delete()
{
$id = $this->input->post('id'); // get the post data
$empdelete=$this->Emp_model->delete($id);
if($empdelete){
echo true;
} else {
echo false;
}
}
这是我的模型删除方法:
function delete($id)
{
$sql = "DELETE FROM employees WHERE id=?";
return $this->db->query($sql,array($id));
}
任何人都可以帮助我如何在页面刷新的情况下做到这一点,我想删除我的记录。
提前谢谢。
试试这个:
$(document).ready(function () {
function ConfirmDelete() {
var x = confirm("Are you sure you want to delete?");
if (x)
return true;
else
return false;
}
$(".empdelete").click(function (e) {
var obj = $(this);
e.preventDefault();
//alert(); what's this do?
if (ConfirmDelete() == false) {
return false;
}
$.ajax({
//alert(); this can't go here
type: "POST",
url: "<?php echo site_url('Employee/delete'); ?>",
cache: false,
data: {id: $(this).attr("id")},
success: function (data) {
console.log('ajax returned: ');
console.log(data);
if (data) {
obj.closest('tr').remove();
alert("Success");
} else {
alert("ERROR");
}
return false;
}
});
});
});
并在单击时删除 HTML:
<button type="submit" class="btn btn-danger btn-xs confirmation empdelete" id="<?php echo $emp->id;?>"><i class='fas fa-times'></i></button>
希望这会对您有所帮助:
你的按钮应该是这样的:
<button type="button" onClick="return ConfirmDelete(this)" class="btn btn-danger btn-xs confirmation empdelete" data-id="<?=$emp->id;?>"><i class='fas fa-times'></i></button>
你的ajax代码应该是这样的:
function ConfirmDelete(obj)
{
var x = confirm("Are you sure you want to delete?");
if (x == true)
{
var id = $(obj).data('id');
alert(id);
if (id != '')
{
//do you ajax here
$.ajax({
type: "POST",
url: "<php echo site_url('Employee/delete'); ?>",
cache: false,
data: {'id': id},
success: function (data) {
console.log('ajax returned: ');
console.log(data);
if (data) {
alert("Success");
} else {
alert("ERROR");
}
return false;
}
});
}
}
else
{
return false;
}
}
您的控制器应该是这样的:
function delete()
{
$id = $this->input->post('id'); // get the post data
$empdelete = $this->Emp_model->delete($id);
if($empdelete)
{
echo true;
} else
{
echo false;
}
exit;
}
您的删除方法应如下所示:
function delete($id)
{
$this->db->where('id',$id);
$this->db->delete('employees');
return $this->db->affected_rows();
}
