Utilizing JavaScript to transmit checkbox values to a database

I am both intrigued and confused by the power of checkboxes. I want to use them to allow customers to select their preferred type of cuisine (fast food, Italian, sushi, etc.). Ultimately, I plan to match these preferences with restaurants offering those types of kitchens. I thought about storing all the choices in a 'kitchen' array[]. Is this the best approach, or should I save each choice as an individual variable? Here is a snippet of my HTML code:

<template name="hello">
    <form class="main form page">
    <div class="form-group">
      <label class="control-label" </label>
    <div class="checkbox">
      <label> <input  name="kitchen" type="checkbox" class="kitchen" id="italian"> Italian</label>
    </div>
    <div class="checkbox">
      <label> <input name="kitchen" type="checkbox" class="kitchen" id="sushi"> Sushi </label>
    </div>
    <div class="checkbox">
      <label><input name="kitchen" type="checkbox" class="kitchen" id="fastfood"> Fast Food </label>
    </div>
  </form>
</template>

The challenge lies in determining the most efficient way to store this data in the MongoDB database.

As I am using Meteor, I have to create a template event:

Template.hello.events({
'submit form': function(e) {
e.preventDefault();

Now, I need to save all the selected results to the database, where 'kitchens' will be the variable added to the Checkbox collection.

var kitchens = {
 fastfood: $(e.target).find('[name=fastfood]').val(),
 sushi: $(e.target).find('[name=sushi]').val(),
 italian: $(e.target).find('[name=italian]').val(),
};

kitchens._id = Checkbox.insert(kitchens);
console.log("added to database");

The current problem is that I cannot determine if the checkbox was checked or not. I came across the following code to convert the check to either "Yes" or "No", but I'm unsure how to incorporate it into my existing code:

function kitchensChecked(id) {
var X = document.getElementById(id);
if (X.checked == true) {
 X.value = "YES";
} else {
X.value = "NO";
};

Could someone assist me in integrating this code or suggest a better method for saving the checkbox results to the Checkbox collection?

Answer №1

In managing checkboxes within my application, I opt to eliminate the id field and instead incorporate a value field for each checkbox:

<input name="kitchen[]" type="checkbox" class="kitchen" value="italian">
<input name="kitchen[]" type="checkbox" class="kitchen" value="sushi">
<input name="kitchen[]" type="checkbox" class="kitchen" value="fastfood">

To simplify the retrieval of checked items, I make use of the pcel:serialize package:

var formObject = $('form.main').serializeJSON();
var checkedItems = formObject.kitchen; // an array containing the checked values

Answer №2

The :checked css selector is used to filter selections and only return input elements that are checked.

var foodTypes = {
 fastfood: $(e.target).find('#fastfood:checked').val(),
 sushi: $(e.target).find('#sushi:checked').val(),
 italian: $(e.target).find('#italian:checked').val()
};
