蔭得到FOLL錯誤：

Uncaught SyntaxError: Unexpected token ILLEGAL 
doDecodeext-all.js:7 
(anonymous function)ext-all.js:7 
o.callbacksm.js:249 
Ext.extend.handleResponseext-all.js:7 
fext-base.js:7 
mext-base.js:7 
(anonymous function)

我發現了一個在線工具：http://json.parser.online.fr/

在這當我粘貼數據EVAL不能評估跨度&風格之間的空間，因爲eval只能執行表達式而不是語句。這裏突破是一個說法：

<span style=\"color\: \#ff0000\;\">

當我做preg_replace("/[ ]+/",' ',$data)它的工作原理。現在問題是我不想讓顯示，因爲我們允許用戶編輯文本&我希望它只顯示爲空格。

哪個方法用於讀取上面的json字符串？ – diEcho

使用JSONLint我看到您的JSON無效。當它們不屬於合法的JSON轉義序列（\", \\, \/, \b, \f, \n, \r, \t, \u<4-digit-hex>）時，您必須轉義反斜槓（\）。

在這種情況下，post_content的值是非法的，因爲它具有像\:和\#這樣的序列。它更改爲以下應該可以解決這個問題（當然，你必須解決您的服務器端代碼，以正確轉義JSON響應）

幫我逃過這個：它不能用反斜槓或雙反斜線工作 –

你不需要手工轉義JSON字符串，你可能不會覆蓋所有的情況和你最終會輸出無效的JSON響應。這個JSON如何生成？ –

至於這個特定的情況，只需要轉義雙引號：'「」'。因此，你的JSON應該如下所示：'{「key」：「」}' –

我想它在Chrome中。只有在JSON字符串中的以下序列不能被Javascript中的eval（）分析。其他人都很好。

\" \\ \n \r
