如果檢查不工作

Question

我想，如果一個複選框被選中的計算乘以2，但不工作

$('#kilometros').keyup(function() { 

    var kilometros = parseFloat($(this).val().toString().replace(",", ".")); 
    var precioKilometros = parseFloat($('#precioKilometros').val()); 
    if ($('#retorno').is(':checked')) { 
     var retorno = 2.0; 
    } else {   
     var retorno = 1.0; 
    } 

    var totalKilometros = (kilometros * precioKilometros * retorno).toFixed(2).toString().replace(".", ","); 
    $('#totalKilometros').html(totalKilometros); 
});

Answer 1

試試這個更改選擇值：

var retorno = $('#retorno').is(':checked') ? 2.0 : 1.0; 

取而代之的是：

if ($('#retorno').is(':checked')) { 
    var retorno = 2.0; 
} else { 
    var retorno = 1.0; 
} 

所以，你的代碼應該是這樣的：

$('#kilometros').keyup(function() { 
    var kilometros = parseFloat($(this).val().toString().replace(",", ".")); 
    var precioKilometros = parseFloat($('#precioKilometros').val()); 
    var retorno = $('#retorno').is(':checked') ? 2.0 : 1.0; 
    var totalKilometros = (kilometros * precioKilometros * retorno).toFixed(2).toString().replace(".", ","); 
    $('#totalKilometros').html(totalKilometros); 
});
