How I concat arrays if I have "i" number of arrays
var i = numberOfarrays;
so now I have to do something like that:
bigArray = row[0].concat(row[1]).concat(row[2])... ...concat(row[i]);
How I can concat i number of arrays?
You can do this :
var bigArray = Array.prototype.concat.apply([], row)
which can be reduced to
var bigArray = [].concat.apply([], row)
Fiddle : http://jsfiddle.net/qGVJe/
Try this,
var row = [[1,2],[3,4],[5,6]]
var bigArray=[];
for(i=0;i<row.length;i++)
bigArray= bigArray.concat(row[i]);
Sample:
var a = ['1','2','3'];
var b = ['4','5','6'];
var final_array = a.concat(b);
//console.log shows final_array is now an an array with: ['1','2','3','4','5','6']
Apply:
bigArray=[];
for(i=0;i<small_array.length;i++){
bigArray.concat(small_array[i]);
}
or
for(i=0;i<small_array.length;i++){
bigArray.push(small_array[i]);
}
