本文实例讲述了JavaScript动态修改网页元素内容的方法。分享给大家供大家参考。具体分析如下：
下面的JS代码当用户点击提交按钮后，通过元素的textContent或者innerHTML动态指定元素的内容
<script type="text/javascript">
function showCard() {
var message = document.getElementById("CCN").value;
var element = document.getElementById("mycreditcardnumber");
element.textContent = message;
//for Firefox
element.innerHTML = message;
//for IE (why can't we all just get along?)
return true;
}
</script>
<form name="dynamic" method="get">
<span>Enter Your Credit Card Number:</span>
<input type="text" id="CCN" name="CCN" value="CCN" />
<input type="button" value="submit" onclick="showCard()" />
</form>
<p>Verify your Credit Card Number:
<span id="mycreditcardnumber">0000-00-0000-00 </span>
</p>希望本文所述对大家的javascript程序设计有所帮助。
