一、子页面是父页面通过window.open弹出的情况
子页面要向父页面传值,只要在document前面加window.opener即可。
如:
1.父页面代码:

<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>
二、子页面是iframe框架中的页面情况

子页面要向父页面传值,只要在document前面加parent即可。
1.父页面代码:

<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>
<body>
    <form id="form1" name="form1" method="post" action="">
        <label> <input type="text" name="textfield" id="textfield" />
        label>
        <iframe id="myiframe" src="/UploadFiles/2021-04-02/Untitled-3.html">    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 aa()
{
    var a=parent.document.getElementByIdx('textfield').value;
    alert(a);
}
script>
<body>
    <form id="form1" name="form1" method="post" action="">
        <label> <input type="submit" name="button" id="button" value="提交"
            onClick="aa()" />
        label>
    form>
</body>
</html>
