點擊按鈕後刪除DIV

Question

我想刪除添加的DIV's（class stripe），然後僅將它應用於可見的DIVs但我卡住了。似乎我不明白腳本如何處理。任何幫助表示讚賞！

$('.item').each(function(i,e){ 
    if (((i+1) % 2) == 0) 
     $(this).wrapAll('<div class="stripe" style="background-color: #887733;" />\n\n'); 
}); 
$(":button").click(function() { 
    var selectedcolor = this.value; 
    var list = $(".item"); 
    $(list).fadeOut("fast"); 
    $(list).each(function(index) { 
     var color = $(this).data("color"); 
     if (color == selectedcolor){ 
      $(this).fadeIn("fast"); 
     } 
    }); 
$('.stripe').contents().unwrap(); 
$('.item:visible').each(function(i,e){ 
    if (((i+1) % 2) == 0) 
     $(this).wrapAll('<div class="stripe" style="background-color: #887733;" />\n\n'); 
    }); 
});

試試這個。我簡化了你的代碼。

function UpdateStrips(){ 
    $('.item:visible:odd').each(function(){ 
     $(this).wrap('<div class="stripe"/>'); 
    }); 
} 

$(":button").click(function() { 
     var selectedcolor = this.value; 
     var list = $(".item"); 
     $(list).fadeOut("fast"); 
     $(list).each(function(index) { 
      if($(this).closest('div.stripe').length) 
       $(this).unwrap(); // unwrap only the elements with parent div with class stripe 
       var color = $(this).data("color"); 
       if (color == selectedcolor) 
       $(this).fadeIn("fast",function() 
       { 
        UpdateStrips(); // invoke callback once the fadeIn completes 
       }); 
     });   
}); 

UpdateStrips(); // invoke on page load

相反的fadeIn and fadeOut，使用show and hide with time delays，那麼你會得到規定的輸出。
