JS 中应用正则移除对应属性的json字符串(高分悬赏)

JS 中使用正则移除对应属性的json字符串(高分悬赏)
例如 移除以下字符串，该如何写正则

"level":1,
"tId":"menutree_2",
"parentTId":"menutree_1",
"open":false,
"isParent":false,
"zAsync":true,
"isFirstNode":true,
"isLastNode":false,
"isAjaxing":false,
"checked":true,
"checkedOld":false,
"nocheck":false,
"chkDisabled":false,
"halfCheck":false,
"check_Child_State":-1,
"check_Focus":false



[解决办法]

JScript code

var _json={"level":1,"tId":"menutree_2","parentTId":"menutree_1","open":false,"isParent":false,"zAsync":true,"isFirstNode":true,"isLastNode":false,"isAjaxing":false,"checked":true,"checkedOld":false,"nocheck":false,"chkDisabled":false,"halfCheck":false,"check_Child_State":-1,"check_Focus":false}；//如果需要判断值，则使用以下的if(_json.level==1){delete _json.level};//如果删除一个指定元素，不需要判断值，则使用以下的delete _json.check_Focus;for(i in _json){    alert(i+"："+_json[i])}
