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:
<scripttype="text/javascript">
functionsaveFile(imgUrl)
{
varoPop=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>
<imgsrc="../mytest.jpg"id="theimage"border="0">
<ahref="#"onclick="saveFile(document.getElementById('theimage').src)">点击这里下载图片</a>
</body>
</html>
方法二：
functionSaveAs5(imgURL)
{
varPop=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();
}
<imgsrc="t_screenshot_17616.jpg"id="DemoImg"border="0"onclick="SaveAs5(this.src)">
