Question

以下字符串作为隐藏输入的值嵌入在我的网站页面中。如果我检索它怎么能把它变成一个实际的对象？

我尝试使用jQuery.parseJSON()但因为它无效JSON它不起作用：

console.log( jQuery.parseJSON( $('#catEntryParams').val()) );

在控制台中返回以下错误：

SyntaxError: Unexpected token i in JSON at position 1

Answer 1

您已经知道您的字符串不是有效的JSON格式，我真的建议您发送有效的JSON字符串，但是如果您真的不能使用eval()在这里发挥作用。

我知道eval是邪恶的根源，但有时你真的没有选择。

保持心情！

使用eval很危险，可以打开代码进行恶意注射！这里的解决方案应该是更改原始源并确保字符串是有效的json（并使用JSON.parse，不 eval）。

如果你真的必须使用eval - 这是一个例子：

Answer 2

问题的根源在于，当信息被放入HTML标记时，它没有被格式化为有效的JSON。 eval solution by Dekel会起作用，但也很脆弱。

允许您将数据加载为 JSON并更安全地执行此操作的“补丁”是格式化字符串。

var input = $("#specialInput").val()

var jsonifiedInput = input.replace(/'/g, '"') // replace single quotes with double quotes
  .replace(/(\w+):/g, '"$1":'); // wrap all keys into double quotes.

var obj = JSON.parse(jsonifiedInput);

console.log("--TYPE:", typeof obj);
console.log(jsonifiedInput);

注意：这仍然是一种比使用eval更安全的解决方法。我仍然强烈建议您修复底层问题并将数据作为正确的JSON接收。

问题在于它依赖于字符串解析和自动替换以形成有效的JSON。

将'（单引号）替换为"（完全翻倍） - 在这种情况下，因为所有值（以及某些键）用单引号括起来。但是，如果您的值为"Resse's pieces"（使用转义引号序列化）或'M&M\'s'（使用双引号序列化），则盲目替换将失败。

用双引号括起来 - 如果密钥是字母数字，则有效 - Coca-cola:的密钥将替换为Coca-"Cola":以及其他问题。

同样，这是临时解决方案，并且适用于此数据集。它可以扩展到其他人，但应该对待主要问题。

将字符串（有效的对象结构，但不是有效的json结构）转换为对象
