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();
