jQuery-从数据库中删除表行后将其删除 [英] jQuery - Remove a table row after it's deleted from database

问题描述

从数据库中成功删除已删除的表行后，我尝试将其删除，但它不起作用.这是我的代码.

I'm try to remove the deleted table row after it's been successfully deleted from the database but it not working. Here is my code.

这有效:

$('table td img.delete').click(function(){
    if(confirm("Are you sure you want to permanently delete this?"))    
    $(this).parent().parent().remove();
    }
});

这不起作用:

$('table td img.delete').click(function(){
    if(confirm("Are you sure you want to permanently delete this?"))    
    $.get('cfc/action.cfc?method=deleteLetter&returnformat=plain', {id: $(this).attr('id')},
        function(data){
            if(data.replace(/^\s+|\s+$/g, '')==='ok'){
            $(this).parent().parent().remove();
            }
        });
    }
});

此记录在此处被删除，但表行仍保留.任何建议将不胜感激.

This record get deleted here but the table row remains. Any suggestion would be much appreciated.

谢谢！

推荐答案

$('table td img.delete').click(function(){
    var currentRow = $(this);
    if(confirm("Are you sure you want to permanently delete this?"))    
    $.get('cfc/action.cfc?method=deleteLetter&returnformat=plain', {id: $(this).attr('id')},
        function(data){
            if(data.replace(/^\s+|\s+$/g, '')==='ok'){
            currentRow.parent().parent().remove();
            }
        });
    }
});

这将起作用.

当您在匿名方法/函数中说这句话时，将向执行代码的那个方法或对象显示此"，但是如果将$(this)分配给变量，则可以在任何地方使用它.

When you say this in anonymous method/function then "this" showing to that method or object where code is executed, But if you assign $(this) to variable then you can use it anywhere.
