使用json和jquery顯示一個類別的子類別

Question

大家好， 請在下面的代碼中找到json數據解析throgh jquery多級別的子類別。 目前有3個子類別，我想要一個關於腳本的建議，我們如何使它能夠顯示子類別的動態腳本。

/**************************************************************/ 
/* Prepares the cv to be dynamically expandable/collapsible */ 
/**************************************************************/ 
function prepareList() { 
    $('#expList').find('li:has(ul)') 
    .click(function(event) { 
     if (this == event.target) { 
      $(this).toggleClass('expanded'); 
      $(this).children('ul').toggle('medium'); 
     } 
     return false; 
    }) 
    .addClass('collapsed') 
    .children('ul').hide(); 

    //Create the button funtionality 
    $('#expandList') 
    .unbind('click') 
    .click(function() { 
     $('.collapsed').addClass('expanded'); 
     $('.collapsed').children().show('medium'); 
    }) 
    $('#collapseList') 
    .unbind('click') 
    .click(function() { 
     $('.collapsed').removeClass('expanded'); 
     $('.collapsed').children().hide('medium'); 
    }) 

}; 


/**************************************************************/ 
/* Functions to execute on loading the document    */ 
/**************************************************************/ 
$(document).ready(function() { 

    var myJSONCategories ={"categories":[{"ic_id":"100002","ic_disp_val":"Campaigns","ic_sub":1,"ic_sub_categories":[{"ic_id":"100021","ic_disp_val":"Campaigns sub categorist","ic_sub":1,"ic_sub_categories":[{"ic_id":"100118","ic_disp_val":"camp 1","ic_sub":0},{"ic_id":"100119","ic_disp_val":"camp 2","ic_sub":0},{"ic_id":"100120","ic_disp_val":"camp 3","ic_sub":0}]}]},{"ic_id":"100002","ic_disp_val":"Products","ic_sub":1,"ic_sub_categories":[{"ic_id":"100021","ic_disp_val":"cxtest","ic_sub":1,"ic_sub_categories":[{"ic_id":"100118","ic_disp_val":"camp 1","ic_sub":0},{"ic_id":"100119","ic_disp_val":"camp 2","ic_sub":0},{"ic_id":"100120","ic_disp_val":"camp 3","ic_sub":0}]}]},{"ic_id":"100002","ic_disp_val":"Campaigns/Products","ic_sub":1,"ic_sub_categories":[{"ic_id":"100021","ic_disp_val":"cxtest","ic_sub":1,"ic_sub_categories":[{"ic_id":"100118","ic_disp_val":"camp 1","ic_sub":0},{"ic_id":"100119","ic_disp_val":"camp 2","ic_sub":0},{"ic_id":"100120","ic_disp_val":"camp 3","ic_sub":0}]}]}]}; 

    var htmlBuilder=''; 

    $.each(myJSONCategories.categories, function(inx, content) { 

      if(inx==0) 
      { 
        htmlBuilder +='<li>'+content.ic_disp_val; 
      }else{ 

        htmlBuilder +='<li>'+content.ic_disp_val;

      if (content.ic_sub==1) 
      {

           len1=content.ic_sub_categories.length-1; 

            if(inx1==0) 
            {

            { 

             len2=cnt_sub1.ic_sub_categories.length-1;

           } 



          }); 



      } 

      htmlBuilder +='</li>'; //Categories End   


    }); 

    $("#expList").html(htmlBuilder); 
    prepareList(); 
}); 

HTML代碼

<ul id="expList"> 


      </ul>

一個遞歸函數能去n小類深！玩的開心。

obj = {"categories":[{"ic_id":"100002","ic_disp_val":"Campaigns","ic_sub":1,"ic_sub_categories":[{"ic_id":"100021","ic_disp_val":"Campaigns sub categorist","ic_sub":1,"ic_sub_categories":[{"ic_id":"100118","ic_disp_val":"camp 1","ic_sub":0},{"ic_id":"100119","ic_disp_val":"camp 2","ic_sub":0},{"ic_id":"100120","ic_disp_val":"camp 3","ic_sub":0}]}]},{"ic_id":"100002","ic_disp_val":"Products","ic_sub":1,"ic_sub_categories":[{"ic_id":"100021","ic_disp_val":"cxtest","ic_sub":1,"ic_sub_categories":[{"ic_id":"100118","ic_disp_val":"camp 1","ic_sub":0},{"ic_id":"100119","ic_disp_val":"camp 2","ic_sub":0},{"ic_id":"100120","ic_disp_val":"camp 3","ic_sub":0}]}]},{"ic_id":"100002","ic_disp_val":"Campaigns/Products","ic_sub":1,"ic_sub_categories":[{"ic_id":"100021","ic_disp_val":"cxtest","ic_sub":1,"ic_sub_categories":[{"ic_id":"100118","ic_disp_val":"camp 1","ic_sub":0},{"ic_id":"100119","ic_disp_val":"camp 2","ic_sub":0},{"ic_id":"100120","ic_disp_val":"camp 3","ic_sub":0}]}]}]}; 

function addCategories(obj) 
{ 
    htmlBuilder = ""; 
    for (var i = 0; i < obj.length;i++) 
    { 
     htmlBuilder +='<li>'+obj[i].ic_disp_val; 

     if (obj[i].ic_sub==1) 
     { 
      htmlBuilder +='<ul>'; 
      htmlBuilder += addCategories(obj[i].ic_sub_categories); 
      htmlBuilder +='</ul>'; 
     } 
     htmlBuilder +='</li>'; 
    } 

    return htmlBuilder; 
} 

document.getElementById("expList").innerHTML = addCategories(obj.categories); 
prepareList();
