Html5怎麼導出圖片

其實很簡單,html

首先須要兩個js文件jquery

  jquery.min.jscanvas

  html2canvas.jsapp

  直接上代碼,幾行就解決了url

<a  id="example1" onclick="exportGrid()" >導出圖表</a>

 

//導出圖表
      function exportGrid() {

          html2canvas($("#exportGrid"), {
              allowTaint: true,
              taintTest: false,
              onrendered: function (canvas) {
                  //canvas.id = "mycanvas";
                  //document.body.appendChild(canvas);
                  //生成base64圖片數據
                  var url = canvas.toDataURL();
                  //如下代碼爲下載此圖片功能
                  var triggerDownload = $("<a>").attr("href", url).attr("download", (new Date()).getTime() + "girds.png").appendTo("body");
                  triggerDownload[0].click();
                  triggerDownload.remove();
              }
          });
      }
