Tableau imbriqué pour la boucle

Question

Je suis bloqué en essayant de comprendre comment faire une boucle dans les tableaux imbriqués.

J'ai un tableau appelé worldShapes qui contient des tableaux enfants. Je veux faire une boucle dans le tableau parent et obtenir tous les tableaux enfants de celui-ci.

Voilà ma tentative:

//Nested array 

worldShapes = [ 

[33,108,66,141,99,174,99,207,132,207,165,207,165,240], 

[132,306,165,306,165,339,165,372,132,405,99,405,99,438,132,438,165,438], 

[198,339,231,339,264,372,297,372,330,405,363,438,396,438], 

[198,174,198,273,231,306,264,306], 

[231,174,231,240,264,273,297,273], 

[396,306,462,306,495,339,495,372,528,405,528,438,561,438,594,471], 

[660,504,561,504,495,504] 

]; 

//trying to loop trough each item in the child array 

(function(){ 
    var wShapes = worldShapes; //create a local variable 
    var wLen = wShapes.length; //store the length as a variable 

     for (var i = 0; i < wLen; i++) { 
      for (var j = 0; j < wShapes[i].length; j++){ 
      console.log(wShapes[i][j]); //this is propably wrong, trying to access the current child item of the current parent array 
      } 
     } 
    }) 

Answer 1

ajouter juste (); à la fin de votre code ;-)

Vous avez simplement oublié d'invoquer votre fonction anonyme

Answer 2

Pour exécuter la fonction, ajoutez ()

(function() { 
    var wShapes = worldShapes; //create a local variable 
    var wLen = wShapes.length; //store the length as a variable 

    for (var i = 0; i < wLen; i++) { 
     for (var j = 0; j < wShapes[i].length; j++) { 
      console.log(wShapes[i][j]); //this is propably wrong, trying to access the current child item of the current parent array 
     } 
    } 
}()); // here 

Fiddle
