javascript json解析錯誤Doubleqoutes

我得到一個錯誤，當我解析JavaScript中的json字符串。「未捕獲的SyntaxError：意外的令牌Z」我知道它的「源」標記中的雙重qoutes，但我該如何解析？javascript json解析錯誤Doubleqoutes

<script type="text/javascript"> 
    var data = '[ { "Outcome": "Success", "Message": null, "Identity": "Request", "Delay": 0.115825, "BaseCurrency": "EUR", "QuoteCurrency": "USD", "Symbol": "EURUSD", "Date": "10/07/2015", "Time": "2:46:32 PM", "QuoteType": "Spot", "Bid": 1.12394, "Mid": 1.12397, "Ask": 1.124, "Spread": 0.00006, "Text": "1 European Union euro = 1.12397 United States dollars", "Source": "SIX Financial Information, Buyer = \"ZKB Zuercher Kantonalbank, Devisen\", Seller = \"ZKB Zuercher Kantonalbank, Devisen\"" }, { "Outcome": "Success", "Message": null, "Identity": null, "Delay": 0, "BaseCurrency": "GBP", "QuoteCurrency": "USD", "Symbol": "GBPUSD", "Date": "10/07/2015", "Time": "2:46:32 PM", "QuoteType": "Spot", "Bid": 1.5293, "Mid": 1.5295, "Ask": 1.5297, "Spread": 0.0004, "Text": "1 British pound sterling = 1.5295 United States dollars", "Source": "SIX Financial Information, Buyer = \"UBS Investment Bank\", Seller = \"UBS Investment Bank\"" } ]'; 
    var obj = JSON.parse(data); 
    for(var key in obj){ 
     console.log(obj[key].Symbol);  
    } 
</script>

我可以使用替換方法，但那不是一個乾淨的解決方案，我認爲。

使用'\「'引用字符串內，你在'Source'是法律有見json.org –

''\''是字符串字面特殊字符*和*。 JSON。在字符串文字中使用JSON並不常見，爲什麼在這裏首先使用JSON？ –

不知道你爲什麼在這裏使用JSON。只是這樣做：

<script type="text/javascript"> 
    var obj = [ { "Outcome": "Success", "Message": null, "Identity": "Request", "Delay": 0.115825, "BaseCurrency": "EUR", "QuoteCurrency": "USD", "Symbol": "EURUSD", "Date": "10/07/2015", "Time": "2:46:32 PM", "QuoteType": "Spot", "Bid": 1.12394, "Mid": 1.12397, "Ask": 1.124, "Spread": 0.00006, "Text": "1 European Union euro = 1.12397 United States dollars", "Source": "SIX Financial Information, Buyer = \"ZKB Zuercher Kantonalbank, Devisen\", Seller = \"ZKB Zuercher Kantonalbank, Devisen\"" }, { "Outcome": "Success", "Message": null, "Identity": null, "Delay": 0, "BaseCurrency": "GBP", "QuoteCurrency": "USD", "Symbol": "GBPUSD", "Date": "10/07/2015", "Time": "2:46:32 PM", "QuoteType": "Spot", "Bid": 1.5293, "Mid": 1.5295, "Ask": 1.5297, "Spread": 0.0004, "Text": "1 British pound sterling = 1.5295 United States dollars", "Source": "SIX Financial Information, Buyer = \"UBS Investment Bank\", Seller = \"UBS Investment Bank\"" } ]; 
    for(var key in obj){ 
     console.log(obj[key].Symbol);  
    } 
</script>

我是Json的新成員，但是謝謝我從來沒有解析過它，它的工作原理如下： – Vazzilly

@Vazzilly，請注意在我的答案中沒有JSON，只有一個對象字面值，JSON（它總是一個字符串）和一個對象字面值之間有區別 –

好吧，謝謝你瞭解到，因爲Data API調用它Json ive叫它Json藏漢 – Vazzilly

您還需要避開反斜槓。代替\"，請鍵入\\"。
