Bagaimana untuk memuat turun gambar apabila mengklik tag?
<img src="images/123.png" alt="">
<a href="#">下载图片</a>

Dua idea:
1.
<html>
<head>
<title> 通过js保存图片到本地 </title>
<meta name="Generator" content="EditPlus">
<meta name="Author" content="">
<meta name="Keywords" content="">
<meta name="Description" content="">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>
</head>
<body>
<input type="button" value="download image" onclick="DownLoadReportIMG('http://www.oursss.com/uploads/photo/1045_2590.jpg?rd=0.9961522558898981');">
</body>
</html>
function DownLoadReportIMG(imgPathURL) {
//如果隐藏IFRAME不存在，则添加
if (!document.getElementById(“IframeReportImg”))
$(‘‘).appendTo(“body”);
if (document.all.IframeReportImg.src != imgPathURL) {
//加载图片
document.all.IframeReportImg.src = imgPathURL;
}
else {
//图片直接另存为
DoSaveAsIMG();
}
}
function DoSaveAsIMG() {
if (document.all.IframeReportImg.src != “about:blank”)
document.frames(“IframeReportImg”).document.execCommand(“SaveAs”);
}
rreeee
