How to push checkbox checked values to js object using jquery each function?

Question

I want the checked checkbox values to store in food javascript object like below:

food: {
{id: 1, name: egg }
{id: 2, name: meat}
}

Here's my code:

var exclude_foods = {};

jQuery('input[name=exclude_food]:checked').each(function(){
   exclude_foods = Object.assign(exclude_foods, {
     id: 1,
     name: jQuery(this).val(),
   });
});

Any suggestion or help?

You can use jQuery's map() method to do what you require.

Note that it's not clear where the id value is intended to come from, so I set it to the index of the checkbox for this example. This can easily be amended to suit your use case.

 $('button').on('click', e => { var exclude_foods = { foods: $('input[name="exclude_food"]:checked').map((i, el) => ({ id: i, name: el.value })).get() }; console.log(exclude_foods); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.1/jquery.min.js"></script> <label> <input type="checkbox" name="exclude_food" value="egg" /> Egg </label> <label> <input type="checkbox" name="exclude_food" value="meat" /> Meat </label> <label> <input type="checkbox" name="exclude_food" value="nuts" /> Nuts </label> <button>Get values</button>
