variables - "var_name" VS "var-name" VS "varName" - Which is supported by the widest variety of languages -


i have seen multi-word variables displayed in 3 ways:

  • with underscore - var_name
  • with hyphen - var-name
  • with capitalization - varname

different languages support different ways. example, can use - (hyphens) in css classnames / ids, not in javascript variable names

my ultimate question is:

which supported across different programming languages, , there advantages or limitations of each?

i think tie between underscore '_' , camel case - or capitalization call it. hyphen gets interpreted operator in many languages, should avoided common naming tool.

all languages have used (fortran, pascal, c/c++, java, php, js, python) differentiate , accept capitalization , underscores in variable names. so, becomes matter of preference. taught camelcase through school have stuck with. creates bit shorter variable name inserting underscores , easier type. having said that, think names underscores bit more readable, , reason enough use them on others. if brain change it's habits, use underscores.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
