i'm trying have ajax call apply formatting elements won't exist until complete. using success function in actual call isn't working. function called element ('.content-cell') isn't found, presumably because doesn't exist yet. majority of similar answers address event delegation not applying styles. am approaching correctly? best method applying styling , handlers after ajax retrieval? $("#calendar-panel").load("url", setupcal()); function setupcal(){ console.log("setupcal"); var cell_width = $('.weekday-cell').width(); if ($('.content-cell').length){ console.log("content cell exists"); } else { console.log("content cell not exist"); } $('.content-cell').css({height:cell_width}); the console output of code is: 'setupcal'; 'content cell not exist'. i think issue might calling setupcal function in line execu...

i cam across following command in makefile: %-nosyms.$(target).elf: %.co $(project_objectfiles) $(interrupt_objectfiles) contiki-$(target).a $(cc) $(cflags) -o $@ $(filter-out %.a,$^) $(filter %.a,$^) $(filter %.a,$^) $(ldflags) source: contiki/cpu/arm/stm32f103/makefile.stm32f103 . does command generate no-symbols-control-file? use of no symbol image file? piece piece analysis: the makefile's target is: %-nosyms.$(target).elf the list of prerequisites is: %.co $(project_objectfiles) $(interrupt_objectfiles) contiki-$(target).a the target recipe is: $(cc) $(cflags) -o $@ $(filter-out %.a,$^) $(filter %.a,$^) $(filter %.a,$^) $(ldflags) makefile's logic is: if *-nosyms.$(target).elf file exists, compare file's timestamp of all pre-requisites. rebuild file (i.e., run given recipe) if of pre-requisites newer. if target marked .phony ) (seems not case), rebuild without checking timestamp. else, go each prerequisite recipe , execute 1 one (...

i'm new dart , learning basics. the dart-homepage shows following: it turns out dart indeed have way ask if optional parameter provided when method called. use question mark parameter syntax. here example: void aligndinglearm(num axis, [num rotations]) { if (?rotations) { // parameter used } } so i've wrote simple testing script learning: import 'dart:html'; void main() { string showline(string string, {string printbefore : "line: ", string printafter}){ // check, if parameter set manually: if(?printbefore){ // check, if parameter set null if(printbefore == null){ printbefore = ""; } } string line = printbefore + string + printafter; output.appendtext(line); output.appendhtml("<br />\n"); return line; } showline("hallo welt!",printbefore: null); } the dart-editor marks questionmark error: multiple markers @ line - unexpec...

this question has answer here: c# delegate instantiation vs. passing method reference 3 answers suppose have delegate in c#: public delegate void exampledelegate(); and somewhere have samplemethod want delegate reference: exampledelegate sample = new exampledelegate(samplemethod); what i've seen people in 2 lines instead this: exampledelegate sample; sample = samplemethod; is same line above in terms of functionality or there (unintended) side effect going on? basically, don't understand difference between: exampledelegate sample = new exampledelegate(samplemethod); and exampledelegate sample; = samplemethod; they seem working same.. there no difference, same. second implicit method group conversion. this syntax introduced in c# 2.0 , covered in programming guide in how to: declare, instantiate, , use delegate .
