jQuery同步addClass和removeClass

我有一个链接到我的代码Fiddle。jQuery同步addClass和removeClass

HTML：

JS：

$(function() { 
    $('table').on('click', '.hide-row', function(e) { 
     console.log('hidden!'); 
     $(this).parent().parent().hide(); 
    }); 


    $('.add-row').click(function(e) { 
    $(this).html('Hide').removeClass('add-row').addClass('hide-row'); 
    $(this).parent().parent().next().show(); 
    }); 


});

我想要做的就是当用户点击 '添加行' 是另一行显示。用户点击的按钮会变成一个按钮，以同时删除它所在的行。

发生什么事是它显示新行并隐藏他们立即点击的行。任何人都知道我在做什么错了？

在此先感谢！

来自click事件的问题，对事件附加到新的元素.add-row（动态添加），你必须使用事件代表团on()：

$('body').on('click', '.add-row', function(e) {

希望这有助于。

$(function() { 
 
    $('table').on('click', '.hide-row', function(e) { 
 
    console.log('hidden!'); 
 
    $(this).parent().parent().hide(); 
 
    }); 
 

 

 
    $('body').on('click', '.add-row', function(e) { 
 
    $(this).html('Hide').removeClass('add-row').addClass('hide-row'); 
 
    $(this).parent().parent().next().show(); 
 
    }); 
 
});

-1

尝试只使用.attr（'class'，'hide-row'），这样做是因为您一次覆盖类属性。

如果你想使动态表中的行，你可以继承人如何实现它。好的做法是：在表格中添加一个ID并删除显示：无行。这个jQuery将添加动态行和切换添加/删除按钮

$(function() { 
    $('#mytable').on('click', '.add-row', function(e) { 
     $('#mytable').append('<tr>' + $('#mytable tr:last-child').html()+'</tr>'); 
    $(this).removeClass('add-row').addClass('remove-row').html('Remove Row'); 
    }); 

    $('#mytable').on('click', '.remove-row', function(e) { 
    $(this).parent().parent().remove(); 
    }); 
});

$(function() { 
    $('.add-row').click(function() { 
    var $hideBtn = $(this).html('Hide').removeClass('add-row').addClass('hide-row'); 
    $hideBtn.click(function() { 
     $(this).parent().parent().hide(); 
    }) 
    $(this).parent().parent().next().show(); 
    }); 
});
