javascript - Sum with jquery not working -

-

i have lot of labels shown on page. want sum values , store them in final_cpa.

html :

<label class="tmpcpa">32.1</label>

js :

function calculate_final_cpa() {         var final_cpa = 0;         var allfilled = false;         $('.tmpcpa').each(function () {             if ($(this).val() != 0) {             final_cpa += parseint($(this).text()) || 0;             allfilled = true;             } else {                 allfilled = false;             }         });              console.log(final_cpa);               console.log(allfilled);     }      var run = setinterval(calculate_final_cpa, 500);

however final_cpa 0 , allfilled remains false.

that because label don't have value attribute .val() function return empty string, have use .text() instead text content inside label element :

if ($(this).val() != 0) {

should : 

if ($(this).text() != 0) {

note : rayon mentioned in comment below text() return string better change 0 in condition string '0'.

hope helps.

function calculate_final_cpa() {    var final_cpa = 0;    var allfilled = false;      $('.tmpcpa').each(function () {       if ($(this).text() != '0') {        final_cpa += parseint($(this).text()) || 0;        allfilled = true;      } else {        allfilled = false;      }    });    console.log(final_cpa);     console.log(allfilled);  }    calculate_final_cpa();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <label class="tmpcpa">32.1</label>

filehandler - java open files not cleaned, even when the process is killed -

-
there java program read files folder, processing , write output files in folder. ran 4 hours , produced few files failed after throwing following error: "too many files" then modified program close (bufferreader , bufferwriter) , started process again. time process failed after starting throwing following error: java.io.filenotfoundexception: <file> (too many open files) then tried running lsof , searched process having no of open files. realized networkmanager. not sure whether should kill process or not. restarted machine. after when ran java program, still got same error. in worst case might possible code still having leaks in terms of not closing everything, still failing after starting process. have feeling lying in system previous run. if start same process in other machine, runs hours before failing. you cannot retain resource between runs of program, if wanted to. leave system without enough resources in theory, though unlikely, restarting...

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
