i just like to ask regarding adding data in a array. But the data which i wanted to put is from a table of input boxes.. Here's the code that i've been practicing to get data:

/

I have an add button that everytime I click that button, it will store data in my_data variable.

i want to produce an output in my variable something like this:

my_data  = [ {plank:"1",thickness:"4",width:"6",length:"8",qty:"1",brdFt:"16"}] 

and if i would add another data again, it will add in that variable and it be something like this:

my_data  = [ {plank:"1",thickness:"4",width:"6",length:"8",qty:"1",brdFt:"16"},
     {plank:"2",thickness:"5",width:"6",length:"2",qty:"1",brdFt:"50"}] 

the code that i have right now is really bad, so please help.

Currently my output: 1,4,6,4,1

• javascript
• arrays
• json

• Fiddles that spam you with a bunch of alerts on load are annoying. – ThiefMaster Commented Jul 15, 2011 at 6:30

You should be able to iterate over all of the textboxes using the following:

function add(e) {
    var obj = {};

    $('#addItem input[type="text"]')
        .each(function(){obj[this.name] = this.value;});
    myItems.push(obj);
}

Where myItems is a global container for your items and #addItem is your form.

Updated jsfiddle.

If you use a form and a submit button then you should be able to implement a non-JavaScript method to add your information so that the site will be accessible to people without JavaScript enabled.

Try this, sorry for modifying your form, but it works well:

HTML:

<form method="post" action="#" id="add_plank_form">
    <p><label for="plank_number">Plank number</label>
    <p><input type="text" name="plank_number" id="plank_number"/></p>

    <p><label for="plank_width">Width</label>
    <p><input type="text" name="plank_width" id="plank_width"/></p>

    <p><label for="plank_length">Length</label>
    <p><input type="text" name="plank_length" id="plank_length"/></p>

    <p><label for="plank_thickness">Thickness</label>
    <p><input type="text" name="plank_thickness" id="plank_thickness"/></p>

    <p><label for="plank_quantity">Quantity</label>
    <p><input type="text" name="plank_quantity" id="plank_quantity"/></p>

    <p><input type="submit" value="Add"/>
</form>

<p id="add_plank_result"></p>

Javascript:

$(document).ready(function() {

    var plank_data = Array();

    $('#add_plank_form').submit(function() {

        // Checking data
        $('#add_plank_form input[type="text"]').each(function() {
            if(isNaN(parseInt($(this).val()))) {
                return false;
            }
        });

        var added_data = Array();
        added_data.push(parseInt($('#plank_number').val()));
        added_data.push(parseInt($('#plank_width').val()));
        added_data.push(parseInt($('#plank_length').val()));
        added_data.push(parseInt($('#plank_thickness').val()));
        added_data.push(parseInt($('#plank_quantity').val()));

        $('#add_plank_form input[type="text"]').val('');

        plank_data.push(added_data);

        // alert(JSON.stringify(plank_data));

        // pute L x W x F for each plank data
        var puted_values = Array();
        $('#add_plank_result').html('');
        for(var i=0; i<plank_data.length; i++) {
            puted_values.push(plank_data[i][1] * plank_data[i][2] * plank_data[i][3] / 12);
            $('#add_plank_result').append('<input type="text" name="plank_add[]" value="' + puted_values[i] + '"/>');
        }

        return false;
    });
});

Iterate through all keys, and add the values. (code written from mind, not tested)

var added = { };
for (var i = 0; i < my_data.length; i ++) {
  var json = my_data[i];
  for (var key in json) {
    if (json.hasOwnProperty(key)) {
      if (key in added) {
        added[key] += json[key];
      } else {
        added[key] = json[key];
      }
    }
  }
}

You can use the javascript array push function :

var data = [{plank:"1",thickness:"4",width:"6",length:"8",qty:"1",brdFt:"16"}];

var to_add = [{plank:"2",thickness:"5",width:"6",length:"2",qty:"1",brdFt:"50"}];

data = data.concat(to_add);

Sorry I only glanced at the other solutions.

$(document).ready(function() {
 var myData=[];
    var myObject = {} 
        $("input").each(function() {
            myObject[this.id]=this.value
        });
     alert(myObject["plank"])
   myData.push(myObject)
});
