我已经使用javascript将html标记的源代码传递为base64String.图像清晰显示.现在我想用javascript将该图像保存到用户的磁盘.
<html>
<head>
<script>
function saveImageAs () {
var imgOrURL;
embedImage.src = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA" +
"AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO" +
"9TXL0Y4OHwAAAABJRU5ErkJggg==";
imgOrURL = embedImage;
if (typeof imgOrURL == 'object')
imgOrURL = embedImage.src;
window.win = open(imgOrURL);
setTimeout('win.document.execCommand("SaveAs")', 0);
}
</script>
</head>
<body>
<a href="#" ONCLICK="saveImageAs(); return false" >save image</a>
<img id="embedImage" alt="Red dot">
</body>
</html>
当我们将imagepath作为标记源传递时,此代码已经起作用,但是当我们将sorce作为base64String传递给tag时,它没有工作.
请在这个问题上建议我.
提前致谢.
