actionscript 3 - Conditional IF Statements in AS3 -


i've written function respond event listener in separate function:

edit: updated working code.

       function greyoutitems(event:event):void {          if (disablecheckbox.selected) {             mycombobox.alpha = 0.5;              mycombobox.enabled = false;             trace("hide combobox success");         }         if (disablecheckbox.selected == false) {             mycombobox.visible = true;             mycombobox.enabled = true;             trace("visible");         }     }

the first if statement works well, hiding combobox when user clicks on checkbox, want user able uncheck same checkbox , make combobox visible again.

ideally, rather setting alpha property 0, i'd prefer if combobox "greyed out" although haven't yet found property so.

your conditionals always true because setting them value in conditional. "=" "assigning" properties only. "==" "equivalent to". if (disablecheckbox.selected = true) sets selected property true , way conditional works, because set value, marked true statement.

function greyoutitems(event:event):void {     if (disablecheckbox.selected == true) {         mycombobox.alpha = 0;         trace("success");     }     if (disablecheckbox.selected == false) {         mycombobox.alpha = 1;         trace("revisible");     } }

in case, should have used else instead of second conditional, however. else statement run faster @ runtime (since doesn't have check second condition, runs else if conditions false). not enough noticeable, adds if doing many times

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
