将字符串转换为JSON对象会引发意外的令牌

Question

我正在尝试将带有转义字符的字符串转换为JSON，但会收到错误

  var str = '[{"name":"content","readonly":false,"value":"<div class=\"blueheading\"><h2>Free Gifts for Him</h2><h3><a href=\"http://abcd.com/free-gifts-with-purchase-for-him.aspx\">View all for Him</a></h3></div>"},{"name":"cached","readonly":true,"value":true}]';
            var myObj = JSON.parse(str);

Answer 1

如果您希望在字符串文字中包含\"，则必须转义\：'\\"'。

这给出了：

var str = '[{"name":"content","readonly":false,"value":"<div class=\\"blueheading\\"><h2>Free Gifts for Him</h2><h3><a href=\\"http://abcd.com/free-gifts-with-purchase-for-him.aspx\\">View all for Him</a></h3></div>"},{"name":"cached","readonly":true,"value":true}]';
var myObj = JSON.parse(str);
