Traversing in JSON Data

Question

I have a JSON data as shown below, I want to traverse into it with loop, but data.length is returning 1 while it should return 2.

Please help me out how can I traverse into data with loop without modifying it

 

var data=[{

"468040": {

"Author": "William von Hagen",

"Title": "Ubuntu Linux Bible"

},

"541115": {

"Author": "Lohith G.N.",

"Title": "Windows Phone 7.5 Application Development with F#"

}

}]

alert(data.length);  //returning 1 instead of 2

 

Answer 1

This is the solution I have created . It however uses Jquery .

The code uses nested looping . Let me know if this is what you intended to achieve .
 

var data=[{

"468040": {

"Author": "William von Hagen",

"Title": "Ubuntu Linux Bible"

},

"541115": {

"Author": "Lohith G.N.",

"Title": "Windows Phone 7.5 Application Development with F#"

}

}]

$.each(data, function( MainIndex, Mainvalue ) {

$.each(Mainvalue, function( SubIndex, Subvalues ) {

alert( SubIndex + " - " + Subvalues["Author"] );

alert( SubIndex + " - " + Subvalues["Title"] );

});

});

Ashish,

Are you in a position to use jquery in the project ?

If so I have worked out a solution .

Hi Priyakaran, Thanks for your valuable reply, But I don't want to modify data, because I am getting it from another service and, this is huge as 5 MBs. I need some way to traverse it without modifying JSON

Hi Ashish ,

 

Ideally the JSON return array value should look like below :

var data=[

{"ID":"468040",

"Author": "William von Hagen",

"Title": "Ubuntu Linux Bible"

},

{

"ID":"541115",

"Author": "Lohith G.N.",

"Title": "Windows Phone 7.5 Application Development with F#"

}

];

alert(data.length);

for(var i = 0; i < data.length; i++) {

alert(data[i].Author);

}

 

Try to get the array value in this format and the looping should work .

I have created a jsfiddle here with the above array format: https://jsfiddle.net/KSPriyaranjan/kjn40jdf/
