下面是儲存一個圖片為樣本,代碼來源於網路,希望能夠給大家帶來一定的協助,代碼如下:

<script type="text/javascript"> function saveFile(imgUrl) {  var oPop=window.open(imgUrl,"","width=1, height=1, top=5000, left=5000");  for(;oPop.document.readyState != "complete"; )  {   if(oPop.document.readyState=="complete")break;  }  oPop.document.execCommand("SaveAs");  oPop.close(); } </script> </head><body><img src="../mytest.jpg" id="theimage" border="0"> <a href="#" onclick="saveFile(document.getElementById('theimage').src)"> 點擊這裡下載圖片 </a> </body></html>

方法二:

function SaveAs5(imgURL)  {  var Pop = window.open(imgURL,"","width=1, height=1, top=5000, left=5000");  for(; oPop.document.readyState != "complete"; )  {  if (oPop.document.readyState == "complete")break;  }  oPop.document.execCommand("SaveAs");  oPop.close();  }<img src="t_screenshot_17616.jpg" id="DemoImg" border="0" onclick="SaveAs5(this.src)">

方法三:

function SaveAs5(imgURL)  {  var Pop = window.open(imgURL,"","width=1, height=1, top=5000, left=5000");  for(; oPop.document.readyState != "complete"; )  {  if (oPop.document.readyState == "complete")break;  }  oPop.document.execCommand("SaveAs");  oPop.close();  }<img src="../t_screenshot_17616.jpg" id="DemoImg" border="0"> <a href="#" onclick="SaveAs5(document.getElementById('DemoImg').src)"> 點擊這裡下載圖片 </a>
