How to animate an array of array with jquery

Question

I have a border 9x9, with lines, columns and squares, like a sudoku border and I want to animate it but I had a few problems when there was multiple animations at same time, so I decided to animate one array of elements each time, for that I putted them in an array and want to animate it one by one but I'm having some issues. There is a piece of my code:

var col,
        row,
        square,
        arr = [];

    col = checkColumn(cell);
    row = checkRow(cell);
    square = checkSquare(cell);

    if(row != null){
        arr.push(row);
    }

    if(col != null){
        arr.push(col);
    }

    if(square != null){
        arr.push(square)
    }

    if(arr.length !=0){
        arr.each(function(){
            enlight($(this));
        });
    }

So, at the moment I can't use arr.each because it says arr isnt a function, If I change arr to:

arr ={}

I can't use .push to add the elements, is there an solution to animate them one by one? Thank you in advance for the help!

The enlight does this:

function enlight(cells){
    var delayTime=0;
    cells.each(function(){
        $(this).parent().delay(delayTime).animate({
            "background-color" : "#ffa500"

        }, 500).delay(100)
            .animate({
                "background-color" : "#ffffff"
            });
        delayTime+=100;
    })

}

So, I want to sent an array each time (row, col and square) to animate one by one not all at same time.

Some HTML:

<div class="board">
      <div class="row">
        <div class="cell">
            <input type="number"  data-column="0" data-line="0">
        </div>
        <div class="cell">
            <input type="number"  data-column="1" data-line="0">
        </div>
        <div class="cell">
            <input type="number"  data-column="2" data-line="0">
        </div>
        <div class="cell">
            <input type="number"  data-column="3" data-line="0">
        </div>
        (more cells 81 in total)

Animate what, it's an array and a number of unspecified functions? — adeneo

col, row and square are arrays of 9 cells each, the enlight function works well but I just want to pass here one of them at a time. — João Silva

You are passing them one at a time, but the animation is probably async, so you have to wait for something, but as that code isn't posted, there's no way to know what to wait for, or for how long ? — adeneo

My problem here isn't, the problem is with the var arr, if I let it arr = [] I cant use the function arr.each(). If I make it arr = {} I can't use the function .push() — João Silva

Maybe I'm just complicating this for you, here's another example -> jsfiddle.net/h8ge7s89/6 — adeneo

You can use .queue(), .promise(), .then(), $.map() to animate elements in sequential order.

// set queue name for `.row` element to `"enlighten"` iterate `.row` elements
$({}).queue("enlighten", $.map($(".row"), function(el, index) {
  // return a function to push to `"enlighten"` queue
  return function(next) {
    // set queue name for `.cell input` elements to `"cells"`
    // iterate `input` elements within `.cell` elements
    $({}).queue("cells", $.map($(".cell > input", el), function(cell) {
      // return a function to push to `"cells"` queue
      return function(_next) {
        // animate `.cell input` elements
        $(cell).delay(100).animate({
            "background-color" : "#ffa500"
        }, 500).delay(100) 
        .animate({
          "background-color" : "#ffffff"
        })
        // when current `.cell input` element animation completes
        // call `_next` function in `"cells"` queue
        .promise().then(_next)           
      }
    // call first function in `"cells"` queue
    // when all `"cells"` queue functions have been called
    // call `next` function in `"enlighten"` queue
    })).dequeue("cells").promise("cells").then(next)
  }
// call first function in `"enlighten"` queue
})).dequeue("enlighten").promise("enlighten")
// do stuff when all functions in `"enlighten"` and `"cells"`
// queues have been called
.then(function() {
  console.log("all animations complete")
});

Can I use queue with the $each? like Martin posted?

guest271314 Over a year ago

Yes, you can use $.each() or $.map(), see Execute function queue in javascript , Want to repeat animation on div for infinity times in jQuery?

guest271314 Over a year ago

@JoãoSilva Note, you can also wrap an array in jQuery() to iterate the array with .each(), e.g., $([10,20,30]).each(function(index, element) {console.log(element)})

guest271314 Over a year ago

You should be able to use $(arr).each(function(){ enlight($(this)); }); , possibly $(cells).each() with you existing javascript

This awnser is a litle bit overkill for this simple problem

The Array type in Javascript does not contain an each function but Jquery does so.

jQuery.each( array, callback )

With this in mind the solution is to use the Jquery each function:

if(arr.length !=0){
    $each(arr,function(){
        enlight($(this));
    });
}

Edit:

You can get more detailed information how to use the JQuery.each function at the officiel docs: http://api.jquery.com/jquery.each/
