jquery - Can I declare and call functions in javascript like in php -


can done? i'm coming form php , trying optimize jquery code i'm writing validation , i'm repeating self lot.

this function:

function errorhint(e,hint){          if(e.parent().hasclass("has-success")){             return false;         }else{             e.addclass('form-control');             e.parent().addclass('has-error');             e.parent().append('<span id="glyph-error" class="glyphicon glyphicon-remove form-control-feedback"></span>');             e.parent().append('<div class="error-hint-empty alert alert alert-warning"><span class="warning-glyph glyphicon glyphicon-warning-sign"></span>'+hint+'</div>');             if(e.parent().hasclass("has-success")){                             e.parent().removeclass("has-success");                             e.parent().find('span#glyph-ok').remove();             }         }      }

and call this:

if($('#username').length){     if(testuser == 0 && $('#username').val() !=='' && $('#username').val() !== null){         hint = 'that user exists!';         errorhint($("#username"),hint);         formvalid = false;     } }

your function should be:

function alert (text){     alert(text); }  $(form).on("submit", function() {     var text = 'this alert text';             alert(text); });

this because there ambiguous call between javascript's native alert , defined alert. changed function name alert, should work fine.

just side thought..

why doing this?

you can use alert(text).

i don't think doing called code optimization. called code lengthification ;)

my advice if aren't doing inside alert() except again alerting, should better off using native alert('some text');

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
