i can set action on click html button. need set action on first click. there way this? button radio in form. javascript maybe? what's important - radio button still might changed. action has done once. this doesn't work function myfunction(i){ oform = document.forms["myform"]; if(oform.elements["field"+i].checked) alert("action done earlier"); else action } the cleanest solution use removeeventlistener to... remove event listener : var mybutton = document.getelementbyid('someid'); var handler = function(){ // dosomething mybutton.removeeventlistener('click',handler); } mybutton.addeventlistener('click', handler); (to make cleaner, wrap in iife, in example below) demonstration

why query using user-defined function on query several joins including outer joins slow? reason function modify string sorts numerically. sorting string means 100 < 99 . function reformats 99 099 . so, 099 < 100 . lets other non-numeric values remain unchanged. the problem query uses function on query joins. takes 27 seconds return 100 rows. same query, function, on 1 table takes subsecond. sql-replacement query on query joins subsecond. query without function on query joins subsecond. primary table tbltests 517 rows. column function operates on text column fldpurity. tbltests fldtestsid autonumber fldpurity text. field size 50. indexed (duplicates ok). 0 length no. here function code. notice different inputs. public function sortablepercent(byval pvar variant) string '------------------------------------------------------------------ ' purpose: formats string may contain numbers or text values.

suppose have alert message like: alert("message"); when command executed, alert box pops message aligned left of alert box. is there way center message inside alert box? well, 1 thing should know can't style alert box. it's system object not css thing . if still want use alert , want move text left right use \t , tab. can figure out how many characters you're going use on line , encase text in \t s. eg: \t text centered \t\n \t in middle of alert \t it's not perfect, it's close 1 can move text center in alertbox. \t works perfect firefox not chrome. love chrome, web developer pain in neck. my alert box looks messy without \t s. google need fix issue... suggestion so it's better to create own. example, jquery ui dialog have here : demo the best thing used display message using toast messages. pops up, show message in beautiful box , pops out in sleek manner. have @ materialize css toasts
