Combining Saurabh Chandra Patel's answerwith Molecular Man's observation, you should have something like this:
结合Saurabh Chandra Patel的回答和Molecular Man的观察，你应该有这样的东西：
JSON.parse('{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}');
回答by Mark Schultheiss
try:
尝试：
var myjson = '{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}';
var newJ= $.parseJSON(myjson);
alert(newJ.TeamList[0].teamname);

Your string is not valid. Double quots cannot be inside double quotes. You should escape them:
您的字符串无效。双引号不能在双引号内。你应该逃避他们：
"{\"TeamList\" : [{\"teamid\" : \"1\",\"teamname\" : \"Barcelona\"}]}"
or use single quotes and double quotes
或使用单引号和双引号
'{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}'

Quick answer, this eval work:
快速回答，这个评估工作：
eval('var obj = {"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}')

Without eval:
没有评估：
Your original string was not an actual string.
您的原始字符串不是实际字符串。
jsonObj = "{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}"
The easiest way to to wrap it all with a single quote.
用单引号将其全部包装起来的最简单方法。
jsonObj = '"{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}"'
Then you can combine two steps to parse it to JSON:
然后可以结合两步解析成JSON：
$.parseJSON(jsonObj.slice(1,-1))
