c# - Open New Tab in ASP.NET web page -


after clicking on asp.net button, redirects correct website on same tab, not in new tab, need do. after clicking button twice, redirects website in new tab. don't know what's wrong code!

the asp.net button control looks this:

<asp:imagebutton id="imagebutton1" runat="server" imageurl="../images/neu.png" onclick="new_btn_click" />

and code run this:

protected void new_btn_click(object sender, eventargs e) {     imagebutton1.attributes.add("onclick", "window.open('new_model_epk.aspx');return false;");    }

what you're describing expect. javascript isn't run until second time because hasn't been added until after click button first time. don't use c#; use this:

<asp:imagebutton id="imagebutton1" runat="server" imageurl="../images/neu.png" onclientclick="window.open('new_model_epk.aspx');return false;" />

any javascript in onclientclick attribute run right away when click element, c# code unnecessary.

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
