我已經看過這個帖子: Jquery - JSON.stringify, array is empty ,也與其他論壇圍繞檢查並搜查谷歌並沒有找到一份像樣的答案。json.stringify返回空白[]一個對象,而不是一個充滿{}

基本上,當我在我用json.stringify保存[]數組,它正確地創建JSON字符串上的一切,但一個數組值,這將是在保存[2]。只是這裏的例子是怎樣的字符串化的職位均爲1和2的數組中:

"1":{"doodleID":"716","tid":"26","outline":"sites/default/files/doodlekin/female24solid.swf","skin":"sites/default/files/doodlekin/female24face.swf","hair":"sites/default/files/doodlekin/female24hair.swf","misc":"sites/default/files/doodlekin/female24lips.swf","addlayer1":"","addlayer2":"","addlayer3":"","doodlename":"Mom","headsize":"95","flip":"true","skincolor":"E8B18C","skinblush":"sites/default/files/skin_color/e8b18c.swf","haircolor":"855D33","mouth":"sites/default/files/mouth/lips_color_d6570a_1.swf","neck":"sites/default/files/neck/pearl_necklace_solid.swf","neck_optlayer":"sites/default/files/neck/pearl_necklace_color.swf","neck_optcolor":"f8e5be"}, 
"2":[] 

它寫出一個正確的,但是當涉及到2的值沒有被正確地解析成JSON字符串。所以你知道保存的數組在1和2的值看起來是什麼樣的(這個數組更大,我只是認爲這應該是你需要知道什麼是錯誤的,如果沒有,請讓我知道。的,而不是2):

'1' ... 
    'doodleID' => "716" 
    'tid' => "26" 
    'outline' => "sites/default/files/doodlekin/female24solid.swf" 
    'skin' => "sites/default/files/doodlekin/female24face.swf" 
    'hair' => "sites/default/files/doodlekin/female24hair.swf" 
    'misc' => "sites/default/files/doodlekin/female24lips.swf" 
    'addlayer1' => "" 
    'addlayer2' => "" 
    'addlayer3' => "" 
    'doodlename' => "Mom" 
    'headsize' => "95" 
    'flip' => "true" 
    'skincolor' => "E8B18C" 
    'skinblush' => "sites/default/files/skin_color/e8b18c.swf" 
    'haircolor' => "855D33" 
    'mouth' => "sites/default/files/mouth/lips_color_d6570a_1.swf" 
    'neck' => "sites/default/files/neck/pearl_necklace_solid.swf" 
    'neck_optlayer' => "sites/default/files/neck/pearl_necklace_color.swf" 
    'neck_optcolor' => "f8e5be" 
'2' ... 
    'doodleID' => "291" 
    'tid' => "27" 
    'outline' => "sites/default/files/doodlekin/male66solid.swf" 
    'skin' => "sites/default/files/doodlekin/male66face.swf" 
    'hair' => "sites/default/files/doodlekin/male66hair.swf" 
    'misc' => "" 
    'addlayer1' => "" 
    'addlayer2' => "" 
    'addlayer3' => "" 
    'doodlename' => "John" 
    'headsize' => "95" 
    'skincolor' => "EEBF7C" 
    'skinblush' => "sites/default/files/skin_color/eebf7c.swf" 
    'haircolor' => "353535" 
    'eyes' => "" 
    'eyes_shadow' => "" 
    'eyes_optlayer' => "" 
    'eyes_optcolor' => "" 
    'mouth' => "sites/default/files/mouth/goatee_solid.swf" 
    'mouth_optlayer' => "sites/default/files/mouth/goatee_color.swf" 
    'mouth_optcolor' => "646464" 

我的問題是爲什麼被保存[2]被從保存取出時使用: POSTDATA = JSON.stringify(保存);

但保存陣列仍然存在時,它顯示2.任何幫助將是巨大的滿,如果你需要更深入的瞭解,我將它送給你。我使用全局變量的原因是因爲我使用了大約10個需要調用該變量的不同函數,我不想通過設計器忽略它。

更新:剛剛意識到這個問題只用Firefox發生得。我正在運行firefox 4 Beta 7.任何可能成爲json.stringify無法正常工作的原因的機會? IRT與Chrome和IE 8.

更新2的工作:用於整個節省:

function userSavedDoodlekin(flag) 
{ 
    // For leave page check 
    addToCartPage = "true"; 

    pID = $("#neededInfo .productID").text(); 
    tID = $("#neededInfo .templateID").text(); 
    pAttr = new Object(); 
    tBg = $("#neededInfo .templateBG").text(); 
    tCoords = $("#neededInfo .templateCoords").text(); 

    $("#neededInfo .productAttr").each(function(){ 
     pAttr[$(this).attr('alt')] = $(this).text(); 
    }); 

    store_doodlekin("product", pID, "productID"); 
    store_doodlekin("product", pAttr, "productAttr"); 
    store_doodlekin("product", tID, "templateID"); 
    store_doodlekin("product", tBg, "templateBG"); 
    store_doodlekin("product", tCoords, "templateCoords"); 

    // Data for post "json" serialized 
    postData = JSON.stringify(saved); 
    flag = ''; 

    // Check for flag 
    if(flag == "true") 
    { 
     flag = '?saved=true'; 
    } 

    // Test before launch 
    // alert(postData); 
    // alert(dump(saved)); 

    // Save the doodlekin and start another loop for the next one to save if another in line. 
    // Data Sent Back: object.status = (1 or 0), object.data = (error message) 

    $.ajax({ 
     type: 'POST', 
     dataType: 'json', 
     data: "data="+postData, 
     url: "/designer/save", 
     success: function(obj){ 
      if(obj.status == 1){ 
       // alert(obj.data); 
       window.location = "/cart"; 
      } 
      else if(obj.status == 0){ 
       alert(obj.data); 
      } 
     }, 
     error: function(XMLHttpRequest, textStatus, errorThrown){ 
      alert("textStatus: "+textStatus); 
      alert("errorThrown: "+errorThrown); 
     } 
    });

這可能是一個錯字的地方,可能是數據本身。你能在JSON創建並顯示的地方發佈代碼嗎?完成括號,括號和分號。編寫工作(或失敗)最小問題示例的行爲經常會揭示問題出在哪裏。 – 2010-12-09 18:04:29

查看帖子的更新,只是我看到它不是這個原因,是因爲現在我知道它適用於Firefox 3.5 + 3.6以及IE 8和Chrome。我只是在我的工作電腦Firefox 4 Beta 7的Firefox中遇到了這個問題。除此之外,當數組被保存時,它在其他瀏覽器上工作得很好。 – John 2010-12-09 20:17:51

您使用的原型的舊版本?我有一個類似的問題,Prototype(或其他庫)添加了不兼容的.toJSON方法來破壞字符串化。
