How to check Object is Empty Or not

[Sironi]

Hi All,

Can you please suggest me how to check Object is empty or not,
If JSON is empty then complier should not go till " return JSON.stringify(arr);" 

if JSON is not empty then complier  should touch return JSON.stringify(arr); line in Code.

issue: script include returning error message like "Empty JSON string", If JSON is empty then 

Script include :

{

var arr=[];
for(var i=0;i<list.length;i++)

obj={

name: list[i].name,

id:list[i].id

},

arr.push(obj);

}

return JSON.stringify(arr);

},

to control this I tried below method to check JSON is empty or not ? but not working

1. Object.Keys(JSON.stringify(arr)).length===0

2. if(JSON.stringify(arr)==='{}')

Please suggest me , how to fix this

You can use a condition to check the length

if (arr.length>0)

{

return JSON.stringify(arr);

}

hi Sanjiv, 

I tried arr.length , it is not working

var obj={}

var arr=[];

arr.push(obj);

g.info(arr.length); // Result it is giving 1

[SanjivMeher]

Yeah. Because you pushed an object in the array. I would do something like this.

var obj={name:"",id:""}

var arr=[];

if (obj.name) // Only if object has a value, push to array

arr.push(obj);

gs.info(arr.length);

Okay, Let me try this method
