今天试了很久，总是不能格式化，错误示例：
var jsonStr = "[{'id':'12343','name':'紧急呼叫','type':'sos','state':'0','recentWarnTime':'1565663748','setting':''},{'id':'12343','name':'异常开关门','type':'intrusion','state':'0','recentWarnTime':'1565663748','setting':'23:00-7:00'},{'id':'12343','name':'不活动','type':'inactive','state':'1','recentWarnTime':'1565663748','setting':'60'},{'id':'12343','name':'燃气泄漏','type':'gasLeakage','state':'1','recentWarnTime':'1565663748','setting':''}]";
var smartlist = new Array();
smartlist = JSON.parse(jsonStr);
正确的示例：
var jsonStr = [{'id':'12343','name':'紧急呼叫','type':'sos','state':'0','recentWarnTime':'1565663748','setting':''},{'id':'12343','name':'异常开关门','type':'intrusion','state':'0','recentWarnTime':'1565663748','setting':'23:00-7:00'},{'id':'12343','name':'不活动','type':'inactive','state':'1','recentWarnTime':'1565663748','setting':'60'},{'id':'12343','name':'燃气泄漏','type':'gasLeakage','state':'1','recentWarnTime':'1565663748','setting':''}];
var smartlist = new Array();
smartlist = JSON.parse(JSON.stringify(jsonStr));
