jQuery 表单验证仅在特定输入上失败

我有一个相当简单的验证函数，它只检查输入是否为空。我在六种不同的形式中使用它，除了一个特定的 input 之外，它似乎在任何地方都可以使用id="driver_first_name"。无法弄清楚为什么它在那里失败。

如果我将所有字段留空，我会在所有字段上出错，并且在我尝试过的任何组合中通常都是正确的，除非driver_first_name我填写了除driver_first_name表单提交之外的所有内容。

关于这里可能发生什么的任何见解？

谢谢！

我的验证功能是这样的：

    function validateForm(form, fields) { //add exit anbimation and reset the container state
    $(".form-input-error").remove();
    var result=false;
    $.each( fields.rules, function( key, value ) {
        if(!$("#"+key+"").val()){
            $("#"+key+"").addClass("form-error");
            $( "<div class='form-input-error'>"+value.message+"</div>" ).insertBefore("#"+key+"");
             result = false;
            //console.log(this.val());
        }
        else{
            $("#"+key+"").removeClass("form-error");
             result = true;
        }   
});
     return result;
}

我在我的提交触发器上调用我的验证，对于不应该为空的字段，通常是这样的：

$(".app-canvas").on('click', ".submitNewDriver", function () {//list all drivers trigger
            var checkInputs = {
        rules: {
            driver_first_name: {
                message: "First Name is Required"
            },
            driver_last_name: {
                message: "Last Name is Required"
            },
            driver_address_street: {
                message: "street is Required"
            }
        }
    };  
    if(validateForm($("#addDriverForm"),checkInputs) == true){
    console.log("form submit");
        addNewDriver();
    }
    else{
        console.log("form errors");
    }
    });
