asp.net jquery validation return false

Question

I have jquery code to validate.

function deneme() {
var url = document.getElementById('ctl00_PostitPanel_frmPostAc_txtLink').value;
var youtubeUrl = url.match(/watch\?v=([a-zA-Z0-9\-_]+)/);
var vimeoUrl = url.match(/^http:\/\/(www\.)?vimeo\.com\/(clip\:)?(\d+).*$/);
if (youtubeUrl) {
    return true;
}
else if (vimeoUrl) {
    return true;
}
else {
    alert('Şimdilik Sadece Youtube ve Vimeo videolarını paylaşabilirsin.');

    return false;
    }

   };

This codes working great.But I want to prevent insert event.It is showing alert.But then inserting item.And code behind.(My controls inside formview.It is not important.Because function working.)

 Button btnKaydet = (Button)frmPostAc.FindControl("btnKaydet");
        btnKaydet.Attributes.Add("onclick","deneme();");

Try this

btnKaydet.Attributes.Add("onclick","return deneme();");

Note that I have added return before the function call. If the function returns false, it should not post back

It worked for a once.But for example I write valid link and then inserted.And then I wrote invalid value but inserted too..
