jQuery append()与appendChild()
这是一些示例代码: function addTextNode(){ var newtext = document.createTextNode(" Some text added dynamically. "); var para = document.getElementById("p1"); para.appendChild(newtext); $("#p1").append("HI"); } <div style="border: 1px solid red"> <p id="p1">First line of paragraph.<br /></p> </div> append()和之间有什么区别appendChild()? 有实时场景吗?
