jquery的JSON字符串处理、单引号双引号的转换

1、jquery的JSON字符串处理

var pwdlevel_val =
 "{"minLength":1,"maxLength":20,"lowercase":false,"uppercase":false,"number":false,"special":false,"limitday":"","maximum":""}";

var jsondata = $.parseJSON(pwdlevel_val);

var minLength = jsondata.minLength;
var maxLength = jsondata.maxLength;
...

2、单引号双引号的转换，有时候给过来的数据可能是单引号的情况，那么需要先转化成双引号，才能解析JSON

var pwdlevel_val =
 "{'minLength':1,'maxLength':20}";

pwdlevel_val = pwdlevel_val.replace(/\'/g,"\"");//g,表示全部替换。
