javascript - Check if element value starts with 'http', if true change class of element -

-

i want check series of elements same class see if value starts 'http' if true elements should have new class added.

$('#btn').click(function () {     if ($('span.value').text().indexof('http') == 0 )      {         $('span.value').addclass('url');      } else {         $('span.value').addclass('noturl');     } });

this jsfiddle i've got far, it's adding new class elements ones don't start 'http'.

i'm not sure problem is?

you need iterate on each span individually:

$('#btn').click(function () {     $('span.value').each(function () {         if ($(this).text().indexof('http') == 0) {             $(this).addclass('url');         } else {             $(this).addclass('noturl');         }     }) });

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
