的jQuery手風琴得到父李

Question

I am trying to get clicked links', all parent item classes using jQuery 

防爆 - 當我在 「建築繪畫與丙烯酸外牆塗料」 我想要得到的類

item150

item149

點擊

item143

i curre爲此寫了一個j查詢，但它給出了一個最接近的li類，但不能得到其他人說它未定義。

jQuery(".menu-sol a").click(function(event) { 
event.preventDefault(); 
clicked=jQuery(this).closest('.parent').attr('class'); 
clicked=clicked.replace('parent ',''); 
clicked2=jQuery('.'+clicked).prev('.parent').attr('class'); 

alert(clicked); 
alert(clicked2); 

}); 

這裏是HTML

我的鞭策是店裏點擊鏈接父項類cookie並加載相同的節點訪問該示例站點刷新頁面時。任何一個可以幫助我獲取父類

謝謝

Answer 1

這會給你的類parent的所有父節點：

$(this).parents('.parent') 

是你問什麼？

下面會給你所有的類名稱的列表，每個父：現在

$(this).parents('.parent').map(function() { 
    return $(this).attr('class').split(/\s+/); 
}).toArray(); 

// [ [ "parent", "item150" ], [ "parent", "item149" ], ... ] 

，如果你知道總會有兩班，而你總是希望第二個，你可以做到以下幾點：

$(this).parents('.parent').map(function() { 
    return $(this).attr('class').split(/\s+/)[1]; 
}).toArray(); 

// [ "item150", "item149" ] 

否則，如果你可以假設，只會有一個item...類，也許這將是一個整潔的方法：

$(this).parents('.parent').map(function() { 
    var classes = $(this).attr('class').split(/\s+/); 
    for(var i = 0; i < classes.length; i++) { 
     if(classes[i].substring(0, 4) == 'item') 
      return classes[i]; 
    } 
}).toArray(); 

// [ "item150", "item149" ]
