Don't talk nonsense, go directly to the code
<input type=button value="下载" onclick="saveit('${path}')">
function saveit(src) {
I1.document.location = src;
savepic();
}
function savepic() {
if (I1.document.readyState == "complete") {
I1.document.execCommand("saveas");
} else {
window.setTimeout("savepic()", 10);
}
}
This download does not support Google Chrome, but supports ie. If there is any other good download method, please leave a message for me. I am also looking for it, but I can't find any other.
