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：
