Calling an HTML file inside a Lightbox modal

The case is as follows:

I use the Modal Lightbox for an image gallery, in the index I have the Thumbs and when clicking opens the modal with the image maximized.

Due to the amount of images it takes a long time to load all.

How can I call an html file containing the images into the modal of the index? So I would not load these images when loading the index.

function openModal() {
  document.getElementById('myModal').style.display = "block";
}

function closeModal() {
  document.getElementById('myModal').style.display = "none";
}

var slideIndex = 1;
showSlides(slideIndex);

function plusSlides(n) {
  showSlides(slideIndex += n);
}

function currentSlide(n) {
  showSlides(slideIndex = n);
}

function showSlides(n) {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("demo");
  var captionText = document.getElementById("caption");
  if (n > slides.length) {slideIndex = 1}
  if (n < 1) {slideIndex = slides.length}
  for (i = 0; i < slides.length; i++) {
      slides[i].style.display = "none";
  }
  for (i = 0; i < dots.length; i++) {
      dots[i].className = dots[i].className.replace(" active", "");
  }
  slides[slideIndex-1].style.display = "block";
  dots[slideIndex-1].className += " active";
  captionText.innerHTML = dots[slideIndex-1].alt;
}

javascript html modal lightbox

  • You can use a <iframe>, but in general I could solve this with a pre-loader and I wouldn’t need iframes, I just can’t provide an example, because your script doesn’t work and for this reason I don’t know where to start to modify it like this.

  • I edited the code and it’s working, I was without the full address of the images.

Solved, I used the script passed by Guilherme Biancardi, instead of calling the html inside the modal I put a button calling the html with the complete modal, it was perfect.

If you want to check the address is http://gabifez12.lsphotografia.com

Thank you so much for your help.

Create a div with an id inside the modal and in javascript put:

$("#SEU_MODAL").click(function(){
    var request = $.ajax({
        url: "SUAPAGINA.html"
    });

    request.done(function (data) {
        $("#ID_DIV_MODAL").html(data);
    });

    request.fail(function () {
        console.log("Ocorreu um erro na requisição");
    });
});

  • Good morning Guilherme Biancardi, It did not work, the modal opens with nothing, does not load the html

  • Good morning, I did the test here and it worked perfectly, make sure the jQuery library is in the scope of your project, and make sure the id #SEU_MODAL is from the button that makes the modal open not the modal id.

  • Guilherme modal is opened in the onclick onclick="openModal();currentSlide(1)" function which references the myModal id within javascript. You could detail how you made it work by posting your complete script?

  • Good afternoon William, could you ask a question? I’m using the script the way I passed and I’m trying to do the following, after the function is called and load the external file, in case get.html and I needed when clicking another link the content that was loaded was dropped to load a new one. Is it possible to implement this in this script? Ex: Click to call get.html, the content is loaded then click to call pic.html the get.html is dropped and pic.html is loaded.

How you asked me for HTML:

<div id="abremodal" class="btn btn-primary " data-toggle="modal" data-target="#minhaModal">Open Modal</div>

<div class="modal fade" id="minhaModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-body">
                    <div id="conteudoModal">
                      nada
                    </div>
                </div>
            </div>
        </div>
    </div>

JS:

$(document).ready(function () {
    $("#abremodal").click(function(){
        var request = $.ajax({
            url: "endereco_da_sua_pagina_html.html"
        });

        request.done(function (data) {
            $("#conteudoModal").html(data);
        });

        request.fail(function () {
            console.log("Ocorreu um erro na requisição");
        });
    });
});

  • Guilherme, I really appreciate the help, but I couldn’t make it work, I added your script but it doesn’t load the html, it displays the images, but when you click it opens the modal with nothing.

  • Open the "F12" console and tell us which error appears. (Remember that my example I use bootstrap and jQuery as api, you need to adapt it to your modal and include jQuery in your HTML)

  • I already have Jquery included <script src="js/jquery.js"></script>, but I couldn’t adapt your script to html. Keeps opening the empty modal, the problem must be as mentioned, I could not adapt it correctly.

  • Guelherme, good afternoon I tried again here and unsuccessfully, if not ask too much I could try to adapt your script in the html I posted, it would help a lot.
