javascript - 将输入值设为数组

Question

如何将输入值设置为数组

var obj = {};
var data = $('#provilege').val();
var obj = eval(data);

//var obj = {"test_1":"1","test_2":"1","test_3":"0","test_4":"0","test_5":"0","test_6":"1","test_7":"0"}

$.each( obj, function( key, value ) { 
    alert("key " + key + " has value " + obj[key]);
  if(value == 0){
        $('#'+ key).addClass('hidden');// hidden only the obj has value = 0
  }
});

使用JSON.parse()来解析JSON。

正确的值格式应该是这样的，我使用了 " 而不是 '，否则解析 JSON 时会出错:

{"test_1":"1","test_2":"1","test_3":"0","test_4":"0","test_5":"0","test_6":"1","test_7":"0"}
