javascript - 将字符串类型解析为 JSON 对象时出错

Question

我正在尝试将字符串解析为 JSON 对象，但它不起作用。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 对象作为返回。有什么想法吗？

jour JSON 字符串应采用 '{"key":"value"}' 格式

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

语法错误:意外的标记 i

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

语法错误:意外的标记'

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

对象 {id: "1"}

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

对象 {id: 1}
