I have a scenario in which i've to store array object in a array.My Javascript code is
var myArray= new Array(5,5);
for(dataIndex in data.data){
for(myIndex in data.data[dataIndex].myObject){
var xrow =data.data[dataIndex].myObject[myIndex].row;
var xcolumn =data.data[dataIndex].myObject[myIndex].column;
myarray[xrow][xcolumn] = data.data[dataIndex].myObject[myIndex];
}
}
but could not store any data object in the array.Can anyone help me out sort this?
It looks like you're coming from PHP, where an array is both a sequence of elements and/or key-value pairs? An array in javascript is just a sequence. (Actually, that's not 100% true, but it is for all intents and purposes.) What you want is an object. An object is a series of key value pairs. The keys and values can be any object, from a string to an array to a function.
var myObj = {};
// or assigning properties up front
var myOtherObj = {'foo': 'bar', 'baz': 12 };
My problem was not declaring and setting value for the javascript array.I was able to acheive it by this.
var YourArrayHere = new Array();
YourArrayHere.length = [first dimension array length here];
for(var count = 0; count < YourArrayHere.length; count++)
{
var TempSecondArray = new Array();
TempSecondArray.length = [sec dimension array length here];
YourArrayHere[count] = TempSecondArray;
}
Ok got a working demo. Took me a while to figure it out. Was fun. It can be optmized.
EDIT: you don't really need a MAX.

I represented data as best as I could to fit your example
var MAX_X = 10;
var MAX_Y = 10;
var data = {
"data":[
{"myObject":[
{"row":0, "column":0},
{"row":0, "column":1},
{"row":0, "column":2},
]
},
{
"myObject":[
{"row":1, "column":0},
{"row":1, "column":1},
{"row":1, "column":2}
]
}
]
};
var result = new Array(MAX_X);
for(var i = 0; i < data.data.length; i++)
{
var temp = new Array(MAX_Y);
var row = (data.data[i].myObject.length > 0) ? data.data[i].myObject[0].row: null;
for(var j = 0; j < data.data[i].myObject.length; j++)
{
console.log('row: ' + data.data[i].myObject[j].row + ', column: ' + data.data[i].myObject[j].column);
temp[data.data[i].myObject[j].column] = [data.data[i].myObject[j]];
}
if(row != null){ result[row] = temp;}
console.log(result);
}
console.log('Final:');
console.log(result);
