javascript - 如何在jQuery中获取输入类型复选框和单选框的类型

Question

jQuery('.pricefield select','.pricefield input').each
    (jQuery(this).change (function (){
        alert(jQuery(this).attr("type")); //it give undefined
        alert(jQuery(this).is(':input')); //it gives false
        var allInputs = jQuery(":input"); 
        alert(allInputs.attr('type'));  //it gives hidden
        get_sum();
    }
));

如何将字段类型识别为select或radio或checkbox？

Answer 1

jQuery('select, input', '.pricefield').on('change', function () {
     var tag  = $(this).prop('tagName'); // return "select", "input" etc
     var type = $(this).prop('type'); // return "radio", "checkbox" etc
});
