我有这个用于验证表单的简单 JS，有人可以告诉我如何获取字段名称（你知道，name=""），它应该是 NameOfSomefield 现在所在的位置：SI 尝试过someField.tagName但没有运气...

function validateForm(){
    var someField = document.forms["nameofofrm"]["someField"].value;
    if (someField==null || someField=="") {
        alert("You cannot leave blank this field: ".NameOfSomefield);
        return false;
    }
}
