本文執行個體講述了javascript元素動態建立實現方法。分享給大家供大家參考。具體分析如下：
document.write只能在頁面載入過程中才能動態建立
可以調用document的createElement方法來建立具有指定標籤的DOM對象,然後通過調用元素的appendChild方法將
新建立元素添加到相應的元素下
舉例如下：
<html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Dom動態建立元素</title> <script type="text/javascript"> function CreateButton() { var div = document.getElementById("divMain"); var myButton = document.createElement("input"); myButton.type = "button"; myButton.value = "我是動態添加的"; //myButton.id="btn"; 注意:如果設定id的話要避免重複 div.appendChild(myButton); //添加到div上 } </script></head><body> <div id="divMain"></div> <input type="button" value="添加元素" onclick="CreateButton()" /></body></html>
希望本文所述對大家的javascript程式設計有所協助。
