javascript - 将字符串类型解析为JSON对象时出错

我正在尝试将我的字符串解析为JSON对象，但是它不起作用。调试代码时出现语法错误。这是我要解析的字符串：

var listString = "{ title: 'MySchema'," + "root: {id:'"  + headID + "',"
+   "title:'" + topHead[0].Designation  + "'," + "subtitle:'" + headName + "',";
liststring = liststring + "{ id: '" + head + "'," + "title: '" + childs[cnt].Designation + "'," + "subtitle: '" + title + "'," + "type: '" +  childs[cnt].Typav + "'";

liststring = getChildNodes(tasksEntries, head, liststring); liststring = liststring + "},";}liststring = liststring + "]}}";} listString = childliststring;

$ .parseJSON（listString）;

我没有得到任何JSON对象作为回报。有什么想法吗？

最佳答案

jour JSON字符串应为'{“ key”：“ value”}'格式

JSON.parse("{id:'1'}");

语法错误：意外的令牌我

JSON.parse("{'id':'1'}");

SyntaxError：意外令牌'

JSON.parse('{"id":"1"}');

对象{id：“ 1”}

JSON.parse('{"id":1}');

对象{id：1}
