jQuery . getjson和转义字符

jQuery .getJSON and escape character

本文关键字：转义字符 getjson jQuery      更新时间：2023-09-26

我调用。getjson，响应是一个JSON字符串，有很多'"字符。在chrome上启动页面时，回调不会触发。我读到它不会触发，因为JSON字符串不是JSON验证。(尽管它通过了JSONLint测试)。

在eclipse的内置web浏览器中启动页面时，回调会触发，因此我可以向您展示响应:

{"merchants": ["{'"loyaltyLevel'": 3, '"distance'": 100.5, '"imageUrl'": '"http://1.bp.blogspot.com/-hY-Kri63wzs/TeHzpxJ2BJI/AAAAAAAAA4Q/pmq2Yvki8WY/s1600/funny-dog-picture-ass.jpg'", '"name'": '"Papa Kapa'", '"credit'": 25000}", "{'"loyaltyLevel'": 3, '"distance'": 100.5, '"imageUrl'": '"http://1.bp.blogspot.com/-hY-Kri63wzs/TeHzpxJ2BJI/AAAAAAAAA4Q/pmq2Yvki8WY/s1600/funny-dog-picture-ass.jpg'", '"name'": '"Papa Kapa'", '"credit'": 25000}", "{'"loyaltyLevel'": 3, '"distance'": 100.5, '"imageUrl'": '"http://1.bp.blogspot.com/-hY-Kri63wzs/TeHzpxJ2BJI/AAAAAAAAA4Q/pmq2Yvki8WY/s1600/funny-dog-picture-ass.jpg'", '"name'": '"Papa Kapa'", '"credit'": 25000}", "{'"loyaltyLevel'": 3, '"distance'": 100.5, '"imageUrl'": '"http://1.bp.blogspot.com/-hY-Kri63wzs/TeHzpxJ2BJI/AAAAAAAAA4Q/pmq2Yvki8WY/s1600/funny-dog-picture-ass.jpg'", '"name'": '"Papa Kapa'", '"credit'": 25000}", "{'"loyaltyLevel'": 3, '"distance'": 100.5, '"imageUrl'": '"http://1.bp.blogspot.com/-hY-Kri63wzs/TeHzpxJ2BJI/AAAAAAAAA4Q/pmq2Yvki8WY/s1600/funny-dog-picture-ass.jpg'", '"name'": '"Papa Kapa'", '"credit'": 25000}"]}

我做了一些调试，确实Javascript不会jsonParse这个

任何想法?

下面是我的代码: 
    <!DOCTYPE html>
<html>
<head>
  <style>img{ height: 100px; float: left; }</style>
  <script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
  <div id="images">
</div>
<script>
$.getJSON("some_url",
  function(data) 
  {
    alert("success");
  });
</script>
</body>
</html>

服务器端代码:

我看到你json lint响应

"{'"loyalty

为什么你有第一个" ?

按照

行
"{'"loyaltyLevel'": 3, '"distance'": 100.5

你会发出->

"{"loyaltyLevel": 3, "distance": 100.5

所以我问为什么第一个是" ?

编辑:

我明白你为什么把"放在开头

将其视为字符串....

类似这样:

 "{"loyaltyLevel": 3,....}",

你应该去掉周围的"

,把它当作一个对象。

这是下面给出的实际JSON。它正在被正确解析，所有变量也都可以访问。

{
    "merchants": [
        {
            "loyaltyLevel": 3,
            "distance": 100.5,
            "imageUrl": "http://1.bp.blogspot.com/-hY-Kri63wzs/TeHzpxJ2BJI/AAAAAAAAA4Q/pmq2Yvki8WY/s1600/funny-dog-picture-ass.jpg",
            "name": "Papa Kapa",
            "credit": 25000
        },
        {
            "loyaltyLevel": 3,
            "distance": 100.5,
            "imageUrl": "http://1.bp.blogspot.com/-hY-Kri63wzs/TeHzpxJ2BJI/AAAAAAAAA4Q/pmq2Yvki8WY/s1600/funny-dog-picture-ass.jpg",
            "name": "Papa Kapa",
            "credit": 25000
        },
        {
            "loyaltyLevel": 3,
            "distance": 100.5,
            "imageUrl": "http://1.bp.blogspot.com/-hY-Kri63wzs/TeHzpxJ2BJI/AAAAAAAAA4Q/pmq2Yvki8WY/s1600/funny-dog-picture-ass.jpg",
            "name": "Papa Kapa",
            "credit": 25000
        },
        {
            "loyaltyLevel": 3,
            "distance": 100.5,
            "imageUrl": "http://1.bp.blogspot.com/-hY-Kri63wzs/TeHzpxJ2BJI/AAAAAAAAA4Q/pmq2Yvki8WY/s1600/funny-dog-picture-ass.jpg",
            "name": "Papa Kapa",
            "credit": 25000
        },
        {
            "loyaltyLevel": 3,
            "distance": 100.5,
            "imageUrl": "http://1.bp.blogspot.com/-hY-Kri63wzs/TeHzpxJ2BJI/AAAAAAAAA4Q/pmq2Yvki8WY/s1600/funny-dog-picture-ass.jpg",
            "name": "Papa Kapa",
            "credit": 25000
        }
    ]
}

使用jsonlinto验证它。如果它是从url返回的，它应该是可见的。
