Javascript - for loop printing only the last iteration

Question

i'd like to print every iteration in my loop (1,2,3,4,5). But at this moment, it's only printing the size of my array (5).

for (var key in mapParseJson.background) {

  //sequelize
  refModelBedrawnins.find({
    where: ['POS_TILE_BE_DRAW_IN =? ',mapParseJson.background[key]            [0]],
    include: [{ model: refModelDrawableObject }]
  }).success(function(result) {

    // I'd like to print every iteration right here
    console.log(key);
  });

}

Show the entire code (i.e. the content of mapParseJson.background) — Max, Sep 29 '14 at 13:15
Are you seeing multiple `5`s or only one? (Note that some console will indicate identical repeat messages with a repeat counter to the left or right of the message.) — apsillers, Sep 29 '14 at 13:18

You need to avoid the closure and save the var "key" value:

for (var key in mapParseJson.background) {
    //sequelize
    (function(k){
         refModelBedrawnins.find({ 
             where: ['POS_TILE_BE_DRAW_IN =? ', mapParseJson.background[k]            [0]],
             include: [{model: refModelDrawableObject}] 
         }).success(function(result) {
             console.log(k);
         });
    })(key);
}

I don't know why, but the function() isn't executed. (i'm using nodejs to print the result). If I console.log('test') in the anonymous function it's just printing nothing – Francis Delgado Sep 29 '14 at 13:28
i've edited, really sorry, I used to do it with functions .. – Hacketo Sep 29 '14 at 13:37
That works perfectly, thank you so much !!! – Francis Delgado Sep 29 '14 at 13:41
