Counting keys in the JSON
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.
It's work Thank you.
