Counting keys in the JSON












1















This is my json



    var json = {
"pages": [{
"name": "page1",
"elements": [{
"type": "text",
"name": "question1"
},
{
"type": "text",
"name": "question2"
},
{
"type": "text",
"name": "question3"
}
]
}]
};


Now I try to count this json with this code



var keyCount  = Object.keys(json).length;

console.log(keyCount);


The output is 1.



But all i need is count this




  • {
    "type": "text",
    "name": "question1",
    },


  • {
    "type": "text",
    "name": "question2",
    },


  • {
    "type": "text",
    "name": "question3",
    }


It's should be 3.
Can someone help me?



  var json = {
"pages": [
{
"name": "page1",
"elements": [
{
"type": "text",
"name": "question1",
},
{
"type": "text",
"name": "question2",
},
{
"type": "text",
"name": "question3",
}
]
},
{
"name": "page2",
"elements": [
{
"type": "text",
"name": "question4"
},
{
"type": "text",
"name": "question5"
},
{
"type": "text",
"name": "question6"
}
]
}
]
}


Now I has another question.



You will see the "name": "page1" now it's has a page1, page2



and when i count page it return me just 3.



Why the return of this not 6



 var count = json.pages[0].elements.length
console.log(count);


6 is from




  • { "type": "text", "name": "question1", },

  • { "type": "text", "name": "question2", },

  • { "type": "text", "name": "question3", }
    question1-3 from page1)


  • { "type": "text", "name": "question4", },


  • { "type": "text", "name": "question5", },

  • { "type": "text", "name": "question6", }
    (question4-6 from page2)

          Yes because you have only one key : page. Also, pages is an array, so you should access the first cell.



          Try counting inside it :



          var count = json.pages[0].elements.length



          I'd recommend using Jsoneditoronline for viewing easily JSON structures.

          You want to count the number of elements under the elements attribute. So you should do



          var keyCount = Object.keys(json.pages[0].elements).length;



          Also elements is an array so



          var keyCount = json.pages[0].elements.length



          will work too.

          You want to count the number of elements under the elements attribute. So you should do



          var keyCount = Object.keys(json.pages[0].elements).length;



          Also elements is an array so



          var keyCount = json.pages[0].elements.length

          You want to count the number of elements under the elements attribute. So you should do



          var keyCount = Object.keys(json.pages[0].elements).length;



          Also elements is an array so



          var keyCount = json.pages[0].elements.length
