javascript实现将文件保存到本地方法汇总

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：
