下面是保存一个图片为示例，代码来源于网络，希望能够给大家带来一定的帮助，代码如下:
<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)"> 点击这里下载图片 </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)"> 点击这里下载图片 </a>
