javascript - building script tags that load in order and accept variables -


in code below instead of using 

<script src="" ></script

i building script up. enable me insert client , calc names - i.e. add variables src calling. leads js errors scripts not loaded in @ right time/ order.

here code

<script type="text/javascript">   var client = 'test'; var calc = 'loancalculator';  var insertscript = function(src){    var element= document.getelementsbytagname('head')[0];    var script= document.createelement('script');    script.type= 'text/javascript';    script.src= src;    element.appendchild(script); }  var insertscriptcontent = function(code){   var element= document.getelementsbytagname('body')[0];   var script= document.createelement('script');   script.type= 'text/javascript';   script.innerhtml  = code;    element.appendchild(script); }      insertscript('http://test.com.au/clients/' + client +'/web/'+calc+'/calculator-lib.js');     insertscript('http://test.com.au/api/configeditor/213?callback=setupconfig');     insertscript('http://test.com.au/clients/' + client +'/web/javascripts/c-app.js');          insertscriptcontent('var __loancalculator = null; var calculator = null; var loadtool = function(){ __loancalculator = abcd("abcd.loancalculator"); var container = $(".loan-calculator-app"); container.empty(); calculator = new __loancalculator.loancalculatorapp(container); calculator.init(); };'); </script> <script type="text/javascript">  $(document).ready(function(){     loadtool(); }); </script>

is there way load top libraries , document .ready runs when these loaded? or there better way add these variables in?

thanks

scripts can loaded @ begining of rendering of page. it's not possible load them when page loaded. can define them in head , call them in specific order.

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 ...
