allow html2canvas to display images and download with images

Question

i have been trying to get an answer for this question for the past 3 days and cant seem to find an answer for my question. my code is very long please forgive me. the reason why my code is long is because i have to take all the variables in consideration i asked the same question and left out some code and when i tried integrating it into my page it did not work.what i want is for my dog image to show in my shirt image when i download it but right now i get a blank download. here is a live code http://torcdesign.com/evol/

 function fctCheck(gender) { var elems = document.getElementsByName("subselector"); for (var i = 0; i < elems.length; i++) { elems.item(i).style.display = "none"; } document.getElementById(gender).style.display = "block"; } $('#men').on('change', function() { $("#mtsm").css('display', (this.value == 'tsm') ? 'block' : 'none'); }); $(document).ready(function() { $('.colore.active').each(function() { $('.container ').css('background-image', 'url(' + $(this).data("image") + ')'); }); $('.colore').on('click', function() { $('.container').css('src', ''); $('.container ').css('background-image', 'url(' + $(this).data("image") + ')'); $('.container7').css('background-image', 'url(' + $(this).data("image-back") + ')'); }); $('#toggler').click(function() { var tmp = $('.container').css('background-image'); $('.container').css('background-image', $('.container7').css('background-image')); $('.container7').css('background-image', tmp); }); });localStorage.option1 = "wow cool option text here" $(document).ready(function() { $('#imajes').change(function() { $('.subselector').hide(); $('.smallimages').hide(); $('#' + $(this).val()).show(); }); $('.smallimages').hide(); var id = $(this).attr('id'); var val = $(this).val(); $('#dog').on('change', function() { $("#bulldogimges").css('display', (this.value == 'bulldog') ? 'block' : 'none'); }); $('img').on('click', function() { $('#fotos').append('<div class="imgdrag"><img class="modal-content" src="' + $(this).attr('src')+ '"/></div>'); $('.imgdrag').draggable(); $('#fotos').droppable(); $('.modal-content').resizable(); $(".download").attr("href",$(this).attr('src')); $(".download").show(); }); }); var download = document.getElementById("download"), result = document.getElementById("previewImage"); function renderContent() { html2canvas(document.getElementById("firstshirt"), { allowTaint: true }).then(function(canvas) { result.appendChild(canvas); download.style.display = "inline"; download.href = result.children[0].toDataURL(); }); } function downloadImage() { } document.getElementById("btn-Preview-Image").onclick = renderContent; download.onclick = downloadImage 

 .container {background-color: transparent; width: 490px; height: 500px; border: 2px solid; position: relative; overflow: hidden; /* Will stretch to specified width/height */ background-size: 490px 500px; background-repeat: no-repeat; }.colore { float: left; width: 20px; height: 20px; margin: 5px; border: 1px solid rgba(0, 0, 0, .2); } .white { background: #FFFFFF; }.black { background: #000000; }

Answer 1

You have not done anything on your download click.

Just try this.

$('#download').click(function(){
   html2canvas($('#firstshirt'),{
    onrendered: function (canvas) {
         var a = document.createElement('a');
         a.href = canvas.toDataURL("image/jpeg").replace("image/jpeg", "image/octet-stream");
         a.download = 'test.jpg';
         a.click();
       }
    });
});
