触发iframe中删除按钮的事件
function get_delbt()
{
var info=window.confirm('確定要刪除該郵件嗎?');
if (info==true)
{
//这句很关键,通过找到mainframe,运用dom访问其中的控件btdel
(删除按钮),执行服务器操作clickdocument.getElementById("mainframe").contentWindow.document.
getElementById("btdel").click();}
}
触发iframe中清空按钮的事件
function get_delallbt()
{
var info=window.confirm('確定要清空該郵件夾嗎?');
if (info==true)
{
document.getElementById("mainframe").contentWindow.document.
