html2canvas에서 이미지를 표시하고 이미지를 다운로드 할 수 있습니다.

Question

지난 3 일 동안이 질문에 대한 답변을 얻으려고 시도했지만 내 질문에 대한 답을 찾지 못하는 것 같습니다. 내 코드가 너무 길어서 용서해주세요. 내 코드가 긴 이유는 모든 변수를 고려해야하기 때문에 같은 질문을하고 일부 코드를 남겼습니다. 내 페이지에 통합하려고 시도했을 때 작동하지 않았습니다. 내가 원하는 것은 내 강아지 이미지 용입니다. 내 셔츠 이미지에 내가 그것을 다운로드하지만 지금은 빈 다운로드받을 표시합니다. 여기에 라이브 코드 http://torcdesign.com/evol/

Answer 1

당신은 당신의 다운로드를 클릭에 아무 짓도하지 않았을 것이다.

그냥 사용해보세요.

$('#download').click(function(){ 
    html2canvas($('#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(); 
     } 
    }); 
});
