jQuery と Ajax を使用してレコードを削除しています。私が書いたコードはレコードを削除しますが、HTML テーブルは再度読み込まれます。これは、回避したいページの更新を意味します。
これが私のコードです:
コメント.php
<script type="text/javascript">
$(document).ready(function(){
function loadList(){
$.ajax({
url: "load_list.php",
cache: false,
success : function(html){
$(".name_list").html(html);
}
});
}
loadList();
$("#Submit").click(function() {
if($(":text").val().length==0)
{
// $(this).next().html("Field needs filling");
$(":text").after('<span class="errorkeyup">Field cannot be empty</span>');
//return false;
success = false;
}
else
{
var name=$("#name").val();
var message=$("#message").val();
$.ajax({
type:"post",
url:"save_list.php",
data:"name="+name+"&message="+message,
success:function(data){
loadList();
}
});
return false;
}
});
$(".delete_button").on("click", function(){
//this deletes the row clicked on with an alert and then reloads the list
var id = $(this).attr("id");
/*var x=window.confirm("Are you sure you want to delete this item?")
if (x==true){*/
$.ajax({
type: "POST",
url: "delete.php",
data: "id="+ id,
success: function(){
loadList();
}
});
// }
return false;
});
});
</script>
