javascript - Calling JQuery Function from Server (asp.net) -

in asp.net project c#, need call jquery function code behind. below function include required script:

<link rel="stylesheet" href="/fancybox/jquery.fancybox-1.3.4.css" type="text/css" media="screen" />     function showfancy(url, title, width, height) {         //alert(url);         $(".fancybox").fancybox({             'width': width,             'height': height,             'autoscale': true,             'transitionin': 'elastic',             'transitionout': 'none',             'type': 'iframe',             'overlaycolor': '#000000',             'overlayopacity': 0.7,             'position': 'fixed',             'scrolling': 'yes',             'modal': false,             'target': "_parent",              "onclosed": function () {                 window.location = window.location;             }          });         $('.fancybox').attr({ href: url, title: title });         $('.fancybox').click();      } 

and way call aspx.cs :

           protected void button1_click(object sender, eventargs e)         { clientscript.registerclientscriptblock(this.gettype(), "script", "showfancy('newform.aspx?ordernumber2=' + $('#txtcontractnumber').val(), 'send', '55%', '65%');", true);             } 

it works fine when call function client side using input button when call server side doesn't call newform.aspx (when uncomment "alert(url);" showfancy function, alert works) . believe there 1 issue way call 'newform'. in advance time , answer.

if want execute javascript on click of button button1 need add onclick attribute in code behind. can add attribute on page_load or onprerender.

button1.attributes.add("onclick", "showfancy(...); return true;") 

return true @ end call server side(button1_click) of button after javascript, if need server actions.
