javascript - JQuery dynamic table totals -


i have table: http://i.imgur.com/v7hmnei.png

the table has data every month, shows selected date.

so, question is: how can total of actual hours , hours per month (visible data)?

this how build table:

var total = 0 ;     var actualtotal = 0 ;     var totaleh = 0;      var table=document.getelementbyid("fbody");     (var i=0;i<user.length;i++)     {          var row=table.insertrow(-1);         var celldate                =       row.insertcell(-1);         var cell2                   =       row.insertcell(-1);         var cell3                   =       row.insertcell(-1);         var cell4                   =       row.insertcell(-1);         var cell5                   =       row.insertcell(-1);         var cell7                   =       row.insertcell(-1);         var cell8                   =       row.insertcell(-1);          var startam                 =       user[i].reg_start_worktime_am;         var finisham                =       user[i].reg_finish_worktime_am;         var startpm                 =       user[i].reg_start_worktime_pm;         var finishpm                =       user[i].reg_finish_worktime_pm;           celldate.innerhtml          =       user[i].reg_date;         cell2.innerhtml             =       user[i].reg_start_worktime_am;         cell3.innerhtml             =       user[i].reg_finish_worktime_am;         cell4.innerhtml             =       user[i].reg_start_worktime_pm;         cell5.innerhtml             =       user[i].reg_finish_worktime_pm;         cell7.innerhtml             =       calctimedifference(startam.substring(0,2), startam.substring(3,5), finisham.substring(0,2), finisham.substring(3,5), startpm.substring(0,2), startpm.substring(3,5), finishpm.substring(0,2), finishpm.substring(3,5));         cell8.innerhtml             =       (calctimedifference(startam.substring(0,2), startam.substring(3,5), finisham.substring(0,2), finisham.substring(3,5), startpm.substring(0,2), startpm.substring(3,5), finishpm.substring(0,2), finishpm.substring(3,5))-user[i].worktime_fullhours).tofixed(2);          if (cell8.innerhtml != "nan")         {              totaleh                 +=      parsefloat((calctimedifference(startam.substring(0,2), startam.substring(3,5), finisham.substring(0,2), finisham.substring(3,5), startpm.substring(0,2), startpm.substring(3,5), finishpm.substring(0,2), finishpm.substring(3,5))-user[i].worktime_fullhours).tofixed(2));             total                   =       (document.getelementbyid('box-table-a').rows.length-1)*user[0].worktime_fullhours;             actualtotal             +=      parsefloat(calctimedifference(startam.substring(0,2), startam.substring(3,5), finisham.substring(0,2), finisham.substring(3,5), startpm.substring(0,2), startpm.substring(3,5), finishpm.substring(0,2), finishpm.substring(3,5)));         }     }

thanks

edit:

fixed:

var totalactuals = 0,     totalextras = 0; var totalhours = 0; var trs = $("#fbody tr").each(function(e) { if($(this).css('display')!='none')     if( $("td:eq(6)", this).text() != 'nan' ) {         // alert("horro! "+$("td:eq(6)", this).text() );         totalactuals += parsefloat( $("td:eq(5)", this).text() );         totalextras += parsefloat($("td:eq(6)", this).text());         totalhours++;     } }); totalhours = totalhours*8;

if understand correctly, table have rows visible, , hidden. and, want calculate totals rows visible.

you can looping through visible rows , accessing columns required calculating totals.

var totalactuals = 0; var totalextras = 0; $.each($('table tr:visible',function() {     totalactuals += $(this).find(".actualhours").val();     totalextras += $(this).find(".totalextras").val(); };)

but return header row. think should assign class rows of table, , use class in jquery selector - $('table .tablerow:visible')

edit

here had assumed have given class "actualhours", "totalextras" div's in actual hours , total hours shown in each row of table. if haven't done so, can use - 

totalactuals += $(this).find("td").eq(5).text(); totalactuals += $(this).find("td").eq(6).text();

this select 5th , 6th columns of row.

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 ...
