I am trying to follow this article http://arabic2000.com/blog/index.php/archives/tag/display-thank-you-after-survey-is-filled but I am lost where he mentioned to find the ID of the onclick validation. I only have 1 page survey. Please sugest. Is he referring to the following code on the newform.aspx page?
<input type="button" name="ctl00$m$g_f46a290b_d993_4347_a2da_868aff18de82$ctl00$toolBarTbltop$RightRptControls$ctl01$ctl00$diidIOSaveItem" value="Finish" onclick="if (!PreSaveItem()) return false;WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$m$g_f46a290b_d993_4347_a2da_868aff18de82$ctl00$toolBarTbltop$RightRptControls$ctl01$ctl00$diidIOSaveItem", "", true, "", "", false, true))" id="ctl00_m_g_f46a290b_d993_4347_a2da_868aff18de82_ctl00_toolBarTbltop_RightRptControls_ctl01_ctl00_diidIOSaveItem" accesskey="S" class="ms-ButtonHeightWidth" target="_self" />
