摘要：遍历jquery对象的代码分享

$("dd").bind("click",function(e){
var $obj = $(e.target);
var i=0;
for (var x in $obj){
i++;
var $hr=(i%5==0) ? "<hr />" : " ";
document.write(x+" "+$hr);
}
});

遍历结果： 0 length prevObject context selector -------------------------------------------------------------------------------- constructor init jquery size toArray -------------------------------------------------------------------------------- get pushStack each ready eq -------------------------------------------------------------------------------- first last slice map end -------------------------------------------------------------------------------- push sort splice extend data -------------------------------------------------------------------------------- removeData queue dequeue delay clearQueue -------------------------------------------------------------------------------- promise attr removeAttr prop removeProp -------------------------------------------------------------------------------- addClass removeClass toggleClass hasClass val -------------------------------------------------------------------------------- bind one unbind delegate undelegate -------------------------------------------------------------------------------- trigger triggerHandler toggle hover live -------------------------------------------------------------------------------- die blur focus focusin focusout -------------------------------------------------------------------------------- load resize scroll unload click -------------------------------------------------------------------------------- dblclick mousedown mouseup mousemove mouseover -------------------------------------------------------------------------------- mouseout mouseenter mouseleave change select -------------------------------------------------------------------------------- submit keydown keypress keyup error -------------------------------------------------------------------------------- find has not filter is -------------------------------------------------------------------------------- closest index add andSelf parent -------------------------------------------------------------------------------- parents parentsUntil next prev nextAll -------------------------------------------------------------------------------- prevAll nextUntil prevUntil siblings children -------------------------------------------------------------------------------- contents text wrapAll wrapInner wrap -------------------------------------------------------------------------------- unwrap append prepend before after -------------------------------------------------------------------------------- remove empty clone html replaceWith -------------------------------------------------------------------------------- detach domManip appendTo prependTo insertBefore -------------------------------------------------------------------------------- insertAfter replaceAll css serialize serializeArray -------------------------------------------------------------------------------- ajaxStart ajaxStop ajaxComplete ajaxError ajaxSuccess -------------------------------------------------------------------------------- ajaxSend show hide _toggle fadeTo -------------------------------------------------------------------------------- animate stop slideDown slideUp slideToggle -------------------------------------------------------------------------------- fadeIn fadeOut fadeToggle offset position -------------------------------------------------------------------------------- offsetParent scrollLeft scrollTop innerHeight outerHeight -------------------------------------------------------------------------------- height innerWidth outerWidth width 再遍历：

$("dd").bind("click",function(e){
var $obj = $(e.target);
var i=0;
for (var x in $obj[0]){
i++;
var $hr=(i%5==0) ? "<hr />" : " ";
document.write(x+" "+$hr);
}
});

遍历结果： querySelector querySelectorAll scrollTop scrollLeft scrollHeight -------------------------------------------------------------------------------- scrollWidth clientTop clientLeft clientHeight clientWidth -------------------------------------------------------------------------------- firstElementChild lastElementChild previousElementSibling nextElementSibling childElementCount -------------------------------------------------------------------------------- children classList setCapture getElementsByClassName getClientRects -------------------------------------------------------------------------------- getBoundingClientRect releaseCapture mozMatchesSelector addEventListener removeEventListener -------------------------------------------------------------------------------- dispatchEvent style contentEditable isContentEditable offsetParent -------------------------------------------------------------------------------- innerHTML offsetLeft offsetTop offsetHeight offsetWidth -------------------------------------------------------------------------------- scrollIntoView id title lang dir -------------------------------------------------------------------------------- className accessKey blur focus click -------------------------------------------------------------------------------- tagName removeAttributeNS removeAttribute getAttribute getElementsByTagName -------------------------------------------------------------------------------- setAttribute getElementsByTagNameNS hasAttributeNS setAttributeNS hasAttribute -------------------------------------------------------------------------------- getAttributeNS nodeName nodeValue nodeType parentNode -------------------------------------------------------------------------------- childNodes firstChild lastChild previousSibling nextSibling -------------------------------------------------------------------------------- attributes ownerDocument namespaceURI prefix localName -------------------------------------------------------------------------------- baseURI textContent setUserData getUserData insertBefore -------------------------------------------------------------------------------- replaceChild removeChild appendChild hasChildNodes cloneNode -------------------------------------------------------------------------------- normalize isSupported hasAttributes compareDocumentPosition isSameNode -------------------------------------------------------------------------------- lookupPrefix isDefaultNamespace lookupNamespaceURI isEqualNode getAttributeNode -------------------------------------------------------------------------------- setAttributeNode removeAttributeNode getAttributeNodeNS setAttributeNodeNS ELEMENT_NODE -------------------------------------------------------------------------------- ATTRIBUTE_NODE TEXT_NODE CDATA_SECTION_NODE ENTITY_REFERENCE_NODE ENTITY_NODE -------------------------------------------------------------------------------- PROCESSING_INSTRUCTION_NODE COMMENT_NODE DOCUMENT_NODE DOCUMENT_TYPE_NODE DOCUMENT_FRAGMENT_NODE -------------------------------------------------------------------------------- NOTATION_NODE DOCUMENT_POSITION_DISCONNECTED DOCUMENT_POSITION_PRECEDING DOCUMENT_POSITION_FOLLOWING DOCUMENT_POSITION_CONTAINS -------------------------------------------------------------------------------- DOCUMENT_POSITION_CONTAINED_BY DOCUMENT_POSITION_IMPLEMENTATION_SPECIFIC hidden tabIndex draggable -------------------------------------------------------------------------------- spellcheck dataset 于是用$("dd")[0].tagName 可以获得tagName. 参考：http://www.mkyong.com/jquery/jquery-how-to-get-the-tag-name/ 然后与$("a")遍历的结果对比

$("a").bind("click",function(e){
var $obj = $(e.target);
var i=0;
for (var x in $obj){
i++;
var $hr=(i%5==0) ? "<hr />" : " ";
document.write(x+" "+$hr);
}
});
