javascript - How to wait rendering before acting on click event? -

-

this issue not shows up. works fine if wait time page load or, if wait enough between clicks change language on drop-down menu. simple multi-language website.

my drop-down in nav-bar looks like:

    ....     <li class="dropdown">        <a class="dropdown-toggle" data-toggle="dropdown" href="#"> <img src="pictures/br-us-sp.png"><b class="caret"></b></a>               <ul class="dropdown-menu" id="langmenu">                   <li><a href="#" id="pt-br" name="pt-br" value="pt-br"><img src="/pictures/1383607461_brazil.png"></a></li>                 <li><a href="#" id="en" name="en" value="en"><img src="/pictures/1383615303_united-states.png"></a></li>                   <li><a href="#" id="es" name="es" value="es"><img src="/pictures/1383615325_spain.png"></a></li>                   <li class="divider"></li>               </ul>       </li>      ....

and events looks like:

template.navigation.events({ 'click #langmenu': function(event){         currentlang = $(event.target).attr('id');   ...    // stuff , re-renders page upon value of currentlang //   ...  } });

when breaks, console shows variable currentlang undefined. assuming because template not rendered in time click event pick value. assumption correct?

how make sure currentlang value?

sorry. have spent couple days goggling out . meteor evolves fast, confused many possible solutions found , tested did not work (deprecated?). can't meteor docs how use blaze functions, when , how use onrendered, etc... there examples?

instead, should use different approach using iron router? if yes, how?

you have block out. current es5 method of doing be

template.navigation.events({ 'click #langmenu': function(event){         settimeout(function(){             currentlang = $(event.target).attr('id');         },100)  } });

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
