JS达成点击下载的小例子
复制代码 代码如下:
<meta http-equiv=”Content-Type” content=”text/html; charset=utf-8″
/>
<a href=”a.txt” id=pic1 onclick=”savepic();return false;”
style=”cursor:hand”>点击下载</a>
<script>
function savepic()
{
if(document.all.a1==null)
{
objIframe=document.createElement(“IFRAME”);
document.body.insertBefore(objIframe);
objIframe.outerHTML= “<iframe
name=a1 style=’width:0;hieght:0′
src=”+pic1.href+”></iframe>”;
re=setTimeout(“savepic()”,1)
}
else
{
clearTimeout(re)
pic =
window.open(pic1.href,”a1″)
pic.document.execCommand(“SaveAs”)
document.all.a1.removeNode(true)
}
}
</script>
