问题描述

该attributes属性包含它们全部：

$(this).each(function() {
  $.each(this.attributes, function() {
    // this.attributes is not a plain object, but an array
    // of attribute nodes, which contain both the name and value
    if(this.specified) {
      console.log(this.name, this.value);
    }
  });
});

您还可以做的是扩展，.attr以便可以像.attr()获取所有属性的普通对象一样调用它：

(function(old) {
  $.fn.attr = function() {
    if(arguments.length === 0) {
      if(this.length === 0) {
        return null;
      }

      var obj = {};
      $.each(this[0].attributes, function() {
        if(this.specified) {
          obj[this.name] = this.value;
        }
      });
      return obj;
    }

    return old.apply(this, arguments);
  };
})($.fn.attr);

用法：

var $div = $("<div data-a='1' id='b'>");
$div.attr();  // { "data-a": "1", "id": "b" }

解决方法

$(this).attr().each(function(index,element) {
    var name = $(this).name;
    var value = $(this).value;
    //Do something with name and value...
});
