Basically I have a loop incrementing i, and I want to do this:
var fish = { 'fishInfo[' + i + '][0]': 6 };
however it does not work.
Any ideas how to do this? I want the result to be
fish is { 'fishInfo[0][0]': 6 };
fish is { 'fishInfo[1][0]': 6 };
fish is { 'fishInfo[2][0]': 6 };
etc.
I am using $.merge to combine them if you think why on earth is he doing that :)
Declare an empty object, then you can use array syntax to assign properties to it dynamically.
var fish = {};
fish[<propertyName>] = <value>;
Do this:
var fish = {};
fish['fishInfo[' + i + '][0]'] = 6;
It works, because you can read & write to objects using square brackets notation like this:
my_object[key] = value;
and this:
alert(my_object[key]);
For any dynamic stuff with object keys, you need the bracket notation.
var fish = { };
fish[ 'fishInfo[' + i + '][0]' ] = 6;
Multidimensional Arrays in javascript are created by saving an array inside an array.
Try:
var multiDimArray = [];
for(var x=0; x<10; x++){
multiDimArray[x]=[];
multiDimArray[x][0]=6;
}
