JQuery not reading user input

Question

I am trying to get the date and department info stored into an array, when a user inputs a value into my HTML. When I look at the console, I see it is being saved as E.fn.init. Here is my HTML code:

<form>
<p><b>Date:</b><input id="date_out" type='date' required /></p> 
<p><b>Department:</b><input id='department_out' type='text' required /></p>

<button  class="btn btn-primary" type="submit" id='submit' >SUBMIT</button>
</form>

And here is my Javascript Code:

let count = 1;

// Handler to Submit Data
    $('#submit').click(() =>{
        $('form').on('submit', function(e){
            e.preventDefault();

const date_out = $("#date_out").val();
const department_out = $("#department_out").val();

let data = [];

        // Iterate over all rows and store data
        for (let i = 1; i <= count; i++){

            // Skip Row if it was Removed
            if (!$(`tr[index=${i}]`).length) continue;

            // Store all Info from this row
            let assetInfo = {
            date_out: $(`#date_out${i}`).val(date_out),
            department_out: $(`#department_out${i}`).val(department_out),
        }
        
        data.push(assetInfo);
        console.log(data);
        }
    });
    });

And the console prints the array as; date_out: E.fn.init, department_out: E.fn.init. How do I get it to save whatever the user inputs in the array?

Also here date_out: $(#date_out${i}).val(date_out) are you trying to set or get the value? — Carsten Løvbo Andersen

Please include all relevant code, Based on this $(#date_out${i}) it looks like you have more elements — Carsten Løvbo Andersen

When I did const date_out = document.getElementById('date_out').value; it still didn't work. But I am trying to get the value — Hope Dunner

I am not quite sure what is your HTML structure but as I understand, you have a table and you want to store each row in a data, here is how I advise you to do it: In my Table called depTable, I have each row with a unique ID like this:

date_out_1
department_out_1

so, when I want to access that, I just want to create that ID which is an easy task while I can get how many rows I have in that table, like this:

// Get ROW COUNT FROM TABLE
var count = $('#depTable tr').length;

Now, if you combine in For loop you will get all IDs

for (let i = 1; i <= count; i++){
    var idDate = "#date_out_" + i;
    var idDep = "#department_out_" + i;
}

here is my all code, hope I helped to solve your problem.

Thank you so much, I should have added more code, but this solved my problem! I just needed the var date_out = "#date_out". This whole time I thought I needed getElementById. But this gets the element, thank you
