Question

我知道我们可以通过使用nodeName来获取节点名称，但是也可以使用jquery设置nodeName吗？基本上我想将节点名称的大小从大写变为小写。

非常感谢

我认为为了正确地执行此操作，您需要替换此标记，如下所述： jQuery: how to change tag name?

不幸的是，这需要您替换整个元素而不仅仅是标记名称，因此如果要替换标记名称，则需要找到一种方法来保留标记的属性以及其中的代码。

幸运的是，我有一个额外的几分钟，所以我创建了这样做的功能：

function change_tag_name(selector,tagname){
    var old_elm = $(selector);
    //Create a jquery element based on selector
    var original_elements = old_elm.get();
    //Get the array of original dom objects
    //Note: We get the original dom objects because jQuery objects do not provide access to the attributes array
    for(var i=0; i< original_elements.length; i+=1){
        var original_element = original_elements[i];
        //Create reference to original element in dom
        var new_elm = $(document.createElement(tagname));
        //Create new element with desired tagname
        new_elm.html($(original_element).html());
        //Add original element's inner elements to new element

        var original_attributes = original_element.attributes;
        //Create an array of the original element's attributes;
        var attributes = new Object();
        //Create a new generic object that will hold the attributes for the new element

        for(var j=0; j<original_attributes.length; j+=1){
            var attribute = original_attributes[j];
            var name = attribute.nodeName;
            //Note: The attributes "nodeName","localName",and "name" appear to have the same value, so I just chose one. It's entirely possible that these could have different values in different contexts...
            //var name = attribute.localName;
            //var name = attribute.name;
            var value = attribute.nodeValue;
            //Note: The attributes "nodeValue","textContext",and "value" appear to have the same value, so I just chose one. It's entirely possible that these could have different values in different contexts...
            //var value = attribute.textContext;
            //var value = attribute.value;
            attributes[name]=value;
        }
        //Populate attributes object
        new_elm.attr(attributes);
        //Assign attributes from old element to new element        
        $(original_element).replaceWith(new_elm);
        //Replace old_element with new element 
    }
}

另外，我认为没有办法保证属性符合原始顺序。

您无法更改nodeName，但您可以使用不同的名称创建一个新节点，复制属性，然后将其替换为另一个。

jQuery使得很难区分属性和属性，你可能能够使用IE专有的outerHTML属性（在其他一些浏览器中支持）和字符串操作，但这在一般情况下不适用于Web

如果有很多这样的节点，那么全局替换“

你能用jquery更改xml的节点名吗？
