Question

How to assign the value to the JSON by providing the index for it..

see the following code,

var jsonVariable = [];
jsonVariable[10] = {1:10};
alert(jsonVariable.toSource());

For the above code the output is,
[,,,,,,,,,{1:10}]
The output i expect and i need is [10 : {1:10}]
How to code to bring the output as i expect… please help me briefly..

Answer 1

You used index-operators ([]), which instanciate a new array and set the element at index 10 to {1: 10}. You actually wanted to use curly braces operators ({}) which instanciate a new object and ad a property 10: {1:10} like that:

var jsonVariable = {};
jsonVariable[10] = {1:10};
alert(jsonVariable.toSource());

Setting members to an array, you can’t simply skip some indices (begin at 10). All uninstaciated indices until yours will forcible be created.
