Jquery ajax request on focusout and enter

Question

I want to request a ajax query when focus on input field is lost or when the user hits enter in the input field.

I have following code for doing so

function editVK() {
    var input = $('.check_vk');
    input.keydown(function () {
        // DO some markup
    }).focusout(function () {
        // execute ajax in function
        calculateVolleKist($(this));
        return false;
    }).on('keypress', function (e) {
        var code = (e.keyCode ? e.keyCode : e.which);
        if (code == 13) {
           // execute ajax in function   
           calculateVolleKist($(this));
           return false;
        }
    });
}

function calculateVolleKist(elem) {
    var regel = elem.closest("tr");
    var article_id = regel.attr('data-article_id');
    var basket_id = regel.attr('data-basket_id');
    var vk = parseFloat(formatToDecimal(elem.val()));

    $.ajax({
        url: 'beltramibasket.php?action=wijzig_volle_kist&basket_id='+basket_id+'&article_id='+article_id+'&vk='+vk,
        type: 'GET',
        dataType: "html",
        async: true,
        success: function(data) {
            $('.basket_body').html("");
            $('.basket_body').html(data);
            editVK();
        }
    });
}

When using this code, my first change in the input fires 1 request. My second change fires 2 request, my 3 request fires 4 request and so on unit my browser chrashes.

EDIT Included 2nd function. My response is HTML , I clear the body and put html back into the body. After that I execute the function editVK again. Because I want to trigger other request when editing the input box.

Answer 1

Try to insert this before your jQuery code:

input.unbind('keydown');
input.unbind('focusout');
input.unbind('keypress');

not 100% sure if this is the source of your problem but it's possible that your are registering the events every time new.

try with this code it is working fine for me

var input = $('.check_vk');
input.focusout(function () {
    // execute ajax in function
    calculateVolleKist($(this));
    return false;
}).keypress(function(event) { 
    if (event.which == 13 || event.keyCode == 13) {
            //code to execute here
             calculateVolleKist($(this));
       return false;
        }
    }
});
