在這個例子中我有一些元件，看起來像這樣：

"children": [{ 
      "id": "", 
      "parent": "", 
      "industry": "", 
      "industry_id": "", 
      "name": "", 
      "percentage": "", 
      "report": "", 
      "description": "", 
      "subsidiary": "", 
      "children": "" 
     }

我想什麼才達到是從原始數組中消除這個「兒童」。到目前爲止，我已經嘗試過這個功能，但它不工作的方式我想：我已經creatd這裏的jsfiddle

function deleteEmpty(data){ 
    if (data.children.length) 
    { 

     nr = data.children.length; 
     for (i=0;i<nr;i++) 
     { 
      // console.log(data.children[i]); 

      if (data.children[i]["id"] == ""){ 
       console.log(data.children[i]); 
       delete data.children[i]; 
      }     
       this.deleteEmpty(data.children[i]); 

     } 
    } 
    return data; 
}

另外：http://jsfiddle.net/fP7NS/2/ 請幫助我或者給我一些提示與我是什麼做錯了。

你只想刪除空白的孩子嗎？ – 2013-03-17 09:35:40

首先（如有必要）將您的JSON字符串轉換爲對象。你的children屬性有時是一個數組，有時是一個空數組，有時是一個空字符串。這使得邏輯有點尷尬。我建議你寫一個函數來測試一個特定的孩子是否爲空。然後你可以這樣寫你的主循環：

function isEmpty(node) { 
    // logic for testing that a node is empty 
} 
function deleteEmptyChildren(node) { 
    // assumes node is not empty 
    if (Array.isArray(node.children)) { 
     node.children = node.children.filter(
      function(child) { 
       if (isEmpty(child)) { 
        return false; 
       } else { 
        deleteEmptyChildren(child); 
        return true; 
       } 
      } 
     ); 
    } 
}
