How to Parse Object

[Supriya25]

Hi All,

Kindly help me how to identify  "info" either it is starting with " { "  or  "[ { "

example 1:
{
data: {

      info: {
          "name": "servicenow"
             }

          }

  }

example 2:
{
data: {

      info: [
           {
          "name":"Servicenow"
            },{
          "name":"SNOW"
            }

          ]

      }

  }

Hi @Supriya25 

You can use:

var obj1 = {
    data: {
        info: {
            "name": "servicenow"
        }
    }
};

//Multiple Info objects
var obj2 = {
    data: {
        info: [{
            "name": "Servicenow"
        }, {
            "name": "SNOW"
        }]
    }
}

//Check if given input is an array
Array.isArray(YOUR_ARRAY);

//Function to check if a given input is JSON
function isJsonObject(value) {
    return typeof value === "object" && value !== null && !Array.isArray(value);
}

gs.info(Array.isArray(obj1.data.info)); //false
gs.info(Array.isArray(obj2.data.info)); //true
gs.info(isJsonObject(obj1.data.info)); //true
gs.info(isJsonObject(obj2.data.info)); //false

Thanks

one last Question , imagine "data" is very huge JSON out of that huge JSON  how to get to know "data" object has "info2" or not. 

var obj1 = {
    data: {
        info:  {
            "name": "servicenow"
        },
      info1:{
       "name":"QL"
        },
      "info2: {
        "name":"TU"
        }
         
    }
};

Hi @Supriya25 

You can do that as follow (notice there are !! not !):

var obj1 = {
    data: {
        info: {
            "name": "servicenow"
        },
        info1: {
            "name": "QL"
        },
        info2: {
            "name": "TU"
        }
    }
};

var obj2 = {
    data: {
        info: {
            "name": "servicenow"
        },
        info1: {
            "name": "QL"
        },
    }
};

gs.info(!!obj1.data.info2); // true
gs.info(!!obj2.data.info2); //false

[Supriya25]

gs.info(!!obj1.data.info2); // true
gs.info(!!obj2.data.info2); //false

Apart of this method any other way to to identify ?

There other ways. You can use this one also:

object.hasOwnProperty(KEY)

Example:

var obj1 = {
    data: {
        info: {
            "name": "servicenow"
        },
        info1: {
            "name": "QL"
        },
        info2: {
            "name": "TU"
        }
    }
};

var obj2 = {
    data: {
        info: {
            "name": "servicenow"
        },
        info1: {
            "name": "QL"
        },
    }
};

gs.info(obj1.data.hasOwnProperty("info2")); // true
gs.info(obj2.data.hasOwnProperty("info2")); //false
