Question

大家好我无法找到解决方案;

<tr><td> Some Code here <input name="forwardings[nodes][amount][]" class="repeatingClass"> some more code here </td> </tr>
<tr><td> Some Code here <input name="forwardings[nodes][amount][]" class="repeatingClass"> some more code here </td> </tr>
<tr><td> Some Code here <input name="forwardings[nodes][amount][]" class="repeatingClass"> some more code here </td> </tr>

我需要总结所有的repeatClass值，当我从其中一个中集中注意力时，我尝试了类似的东西，但是无法处理这个;

 $('.repeatingClass').focusout(function(){
     var totalPoints = 0;
   $('.repeatingClass').each(function(){
     totalPoints += $('.repeatingClass').val();
   });
   alert(totalPoints);
 });

我该怎么办？问候

输入中的空值被解释为字符串。因此，您应首先查看是否有值，如果有，请在致电parseInt或parseFloat

后将其添加到总计中

$(function(){

     $('.repeatingClass').focusout(function(){
         var totalPoints = 0;

       $('.repeatingClass').each(function(){

           if ($(this).val())
               totalPoints += parseInt($(this).val());
       });

       alert(totalPoints);

     });

});
