jQuery-从数据库中删除表行后将其删除

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.
