注：window.parent 是iframe頁面調用父頁面對象，當我們想從iframe內嵌的頁面中訪問外層頁面是可以直接利用window.parent獲 取；iframe就存在於父頁當中
例：a.jsp父頁
<div>
輸入值：
<input type="text" name="username" id="username" /><br />
<iframe src="b.html" width="400px" height="300px"></iframe>
</div>
b.html子頁
<script type="text/javascript">
function getpValue()
{
document.getElementByIdx_x("span1").innerText=window.parent.document.getElementByIdx_x ("username").value;
}
</script>
<body>
<span>文本框值爲：</span><span id="span1"></span><br />
<input type="button" value="獲取父窗口內的文本框值" οnclick="getpValue();">
</body>
window.opener 是window.open或超鏈接<a> 打開的子頁面調用父頁面對象
例：a.jsp父頁
<script type="text/javascript">
function openB()
{
window.open('b.html','b','width=400,height=200,status=no,toolbar=no,
menubar=no,location=no,resizable=yes,left=200,top=100');
}
</script>
<div>
輸入值：
<input type="text" name="username" id="username" /><br />
<input type="button" value="打開窗口B" οnclick="openB();" /><br />
<a href="b.html" target="_blank">超鏈接打開B頁面</a>
</div>
b.html子頁
<script type="text/javascript">
function getpValue()
{
document.getElementByIdx_x("span1").innerText
=window.opener.document.getElementByIdx_x("username").value;
}
</script>
<body>
<span>文本框值爲：</span><span id="span1"></span><br />
<input type="button" value="獲取父窗口內的文本框值" οnclick="getpValue();">
</body>
