javascript - 设置子节点的属性

Question

我如何将属性添加到“testTwo”标签？ Javascript 菜鸟..

        var XML = document.createElement("test");
        var Node = document.createElement("testOne");
        Node.setAttribute("id", "0");
        Node.setAttribute("random", "0"); 
        Node.appendChild( document.createElement("testTwo"));

        XML.appendChild(Node);

        console.log(XML.innerHTML);

Answer 1

预先创建testTwo 节点。示例代码为:

var XML = document.createElement("test");
var Node = document.createElement("testOne");
Node.setAttribute("id", "0");
Node.setAttribute("random", "0"); 
var testtwo = document.createElement("testTwo");
testtwo.setAttribute("attr", "attrval");
Node.appendChild(testtwo);

XML.appendChild(Node);

console.log(XML.innerHTML);
