[javascript] jquery 입력에서 이름 필터링

This works:

$('input[name^="record_"]').each(function() {
    total += this.value * (parseInt(this.name.substr(7),10)<4 ? 8 : 1);
    });

It also avoids creating unnecessary variables or lookups inside the loop, which should make it more efficient.

다음과 같이 할 수 있습니다.

$('input[name^="record_"]').map(function() { 
    var name = this.name;
        var number = name.replace('record_', '')
            if (number > 3){
                     total += $(this).val() * 1; 
                         }else{
                                  total += $(this).val() * 8; 
                                      }
                                          console.log(number);
                                          
                                          
                                          });
                                          

-------------------

이 시도:

$( 'input[name^="record_"]' ).each(function () {
    var n = +this.name.split( '_' )[1];
        total += this.value * ( n > 3 ? 1 : 8 );
        });
