子页面赋值给父页面:window.opener.document.getElementById

window.opener 返回的是创建当前窗口的那个父窗口的引用,比如点击了a.htm上的一个链接而打开了b.htm,然后我们打算在b.htm上输入一个值然后赋予a.htm上的一个id为“name”的textbox中,就可以写为:indow.opener.document.getElementById("name").value = "输入的数据";

1.页面代码:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档title>
head>
<script language="javascript">
function tanchu()
{
    window.open("Untitled-5.html");   
}
script>
<body>
    <form id="form1" name="form1" method="post" action="">
        <label> <input type="submit" name="button" id="button" value="提交"
            onclick="tanchu()" />
        label> <label> <input type="text" name="textfield" id="textfield" />
        label>
    form>
</body>
</html>

2.子页面代码:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档title>
head>
<script language="javascript">
function aaa()
{
    window.opener.document.getElementByIdx('textfield').value='123123123';
}
script>
<body>
    <form id="form1" name="form1" method="post" action="">
        <label> <input type="submit" name="button" id="button" value="提交"
            onclick="aaa()" />
        label>
    form>
</body>
</html>
