I want to declare an Array with 4 dimensions, then loop some stuff with for() - and then the program breaks. Here is my code:

Typescript:

MoarInfo: any = [[[]]];

JavaScript:

constructor(){

 for(var i = 0; i < this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth].length; i++){

  for(var a = 0; a < this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth][i].length; a++){

    for(var b = 0; b < this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth][i][a].length; b++){



      this.MoarInfo[i][a][b][0] = this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth][i][a][b][0];

      this.MoarInfo[i][a][b][1] = this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth][i][a][b][1];

      this.MoarInfo[i][a][b][2] = 'DetailsSpan';



    }

  }

}

}

The Problem definitively lies at the MoarInfo array. I tested my code without it, and it works fine. I tried the following possibilities for the Typescript array declaration as well:

Moarinfo: any; MoarInfo = ; MoarInfo = [[[]]]; MoarInfo: any = [[[]]];

And in JavaScript, I tried to declare a new Array, and then push some elements on the MoarInfo array, with different functions (split, unshift, push, concat) and nothing worked.

What am I doing wrong?

Check the size of this.MoarInfo[i][a][b]. You are trying to get the value by index 0,1,2. Looks like its size is less than 2 which is causing this error.

      if(this.MoarInfo[i][a][b].size > 0){

         this.MoarInfo[i][a][b][0] = this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth][i][a][b][0];

      }

       if(this.MoarInfo[i][a][b].size > 1){

           this.MoarInfo[i][a][b][1] = this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth][i][a][b][1];

       }

       if(this.MoarInfo[i][a][b].size > 2){

           this.MoarInfo[i][a][b][2] = 'DetailsSpan';

       }

Okay, I figured it out for myself. You have to set the elements of the dimensions from the array at first blank, then you can fill them with content. First I declared an Array in TypeScript like this AnArray = ;. Then I switched to JavaScript ( to the constructer() function ) and filled it with blank elements. I archieved this with this.AnArray.push();. If you want to set elements for the first dimension use push();, if you want an element for the 4th dimension, use push([[]]);. And you can set your content space like this push([[['E1',0,0,'E2']]]);. Now you can use follwing syntax:

alert( this.AnArray[0][0][0][3] ); //returns 'E2'

The complete code from my project now works fine and looks like this:

 for(var i = 0; i < this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth].length; i++){

  this.test.push([[]]);



  for(var a = 0; a < this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth][i].length; a++){

    this.test[i].push([]);



    for(var b = 0; b < this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth][i][a].length; b++){

      this.test[i][a].push(['',0,'']);



      this.test[i][a][b][0] = this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth][i][a][b][0];

      this.test[i][a][b][1] = this.AllDataInfo[this.KontoAktuellYearIndex][this.KontoAktuellMonth][i][a][b][1];

      this.test[i][a][b][2] = 'DetailsSpan';



    }

  }

}

I wonder if there is a better way than using arrays, but if you want it too, you can do it like this.
