本文給大家匯總介紹了3中使用javascript實現將文件保存到本地的方法，非常的簡單實用，有需要的小伙伴可以參考下。

下面是保存一個圖片為示例，代碼來源于網絡，希望能夠給大家帶來一定的幫助，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)"> 點擊這里下載圖片 </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">
