create textboxes and Insert data at page loading

Question

I would like to know how can I create textboxes and insert data at page load.

What I'm trying to do is open an array string from a database, create the textboxes and populate the textboxes at page load.

I have an array string from an ms sql database that looks something like this

test,test;bla;bla2;test44;test55;test66

I separated each individual array with ; and I would like to create textboxes and insert the values into a textbox, one-by-one, so the end result would look like this:

enter image description here

I don't know how to do it using the code below.

Whatever I try I mess up the add/remove functions or I end up cloning all textboxes when the plus button is clicked.

THANKS

Here is a solution that works :

$(function() {
    var clone = function(tmpl) {
            return $((tmpl.clone()).html())
        },
        $template = $('<div>').addClass("entry input-group col-xs-9").append(clone($('#template_add_form'))),
        formArray = [  ], // init array enpty
        $formEntries = $('#entries');

    $(document).on('click', '.btn-add', function() {
        formArray.push(clone($template));
        updateForm();

        // set focus to adding row = last element in array
        $(formArray).last()[0]
            .find('input')
            .first()
            .focus();
    });

    // remove not working yet

    $(document).on('click', '.btn-remove', function(evt) {
        var id;

        // iterate over formArray to find the currently clicked row
        $.each(formArray, function(index, row) {
            if ( row.has(evt.currentTarget).length == 1 ) {
                id = index; // click target in current row
                return false; // exit each loop
            }
        });
        formArray.splice(id, 1);
        updateForm();
    });
    
    var addToForm = function (stringValue) {
        values = stringValue.split(";");
        for (var i = 0; i < values.length; i+=3) {
            var newLine = clone($template);
            var fields = newLine.find('.form-control');
            var toAdd = Math.min(values.length-i, 3);
            for (var j = 0; j < toAdd; j++) {
                 fields[j].value = values[i+j];
            }
            formArray.push(newLine);
        }
     }

    var updateForm = function() {
        // redraw form --> problem values are cleared!!
        var lastIndex = formArray.length - 1,
            name; // stores current name of input

        $formEntries.empty(); // clear entries from DOM becaue we re-create them
        $.each(formArray, function(index, $input) {
            // update names of inputs and add index
            $.each($input.find('input'), function(inputIndex, input) {
                name = $(input).attr('name').replace(/\d+/g, ''); // remove ids
                $(input).attr('name', name);
            });

            if (index < lastIndex) {
                // not last element --> change button to minus
                $input.find('.btn-add')
                     .removeClass('btn-add').addClass('btn-remove')
                     .removeClass('btn-success').addClass('btn-danger')
                     .html('<span class="glyphicon glyphicon-minus"></span>');
            }

            $formEntries.append($input);
        });
    };

    addToForm("2;3;4;5;6;7");
    formArray.push(clone($template));
    updateForm();
    $('#template_add_form').remove();
    
});

.entry:not(:first-of-type)
{
    margin-top: 10px;
}

.glyphicon
{
    font-size: 12px;
}

Here's what I changed to your code :

Changed the template which was a <script> to a <div>, and hid it by default using style="display: none;" :

<div id="template_add_form" type="text/template" style="display: none;">
Initialized array empty, so that we can put our own first line : formArray = [ ],

Created a function to add a string in the form :

var addToForm = function (stringValue) {
    values = stringValue.split(";");
    for (var i = 0; i < values.length; i+=3) {
        var newLine = clone($template);
        var fields = newLine.find('.form-control');
        var toAdd = Math.min(values.length-i, 3);
        for (var j = 0; j < toAdd; j++) {
             fields[j].value = values[i+j];
        }
        formArray.push(newLine);
    }
 }

At the end, I added some example data, then pushed an empty line and updated the form :
```
addToForm("2;3;4;5;6;7");
formArray.push(clone($template));
updateForm();
```
EDIT : I also deleted the template div at the end so that it isn't taken into the form when you submit :

$('#template_add_form').remove();

To be able to do that, I cloned it entirely at start :

$template = $('<div>').addClass("entry input-group col-xs-9").append(clone($('#template_add_form'))),
