$(document).ready(function() {
$('a[href][href!="#"]').click(function() {
SetSelfTarget(this);
});
$('input').click(function() {
SetSelfTarget(this);
});
});
function SetTarget() {
var htmTarget = document.getElementsByTagName("head");
if ((undefined != htmTarget) && (0 < htmTarget.length)) {
var b = htmTarget[0].getElementsByTagName("base");
if ((undefined != b) && (0 < b.length)) {
b[0].target = "download";
}
}
}
function SetSelfTarget(obj) {
if (obj.id != "btn_Export") {
var htmTarget = document.getElementsByTagName("head");
if ((undefined != htmTarget) && (0 < htmTarget.length)) {
var b = htmTarget[0].getElementsByTagName("base");
if ((undefined != b) && (0 < b.length))
b[0].target = "_self";
}
}
}
</script>
<asp:Button ID="btn_Export" runat="server" Text="导出" OnClick="btn_Export_Click" OnClientClick="SetTarget()" />
