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：
无标题文档title><BR>head><BR><script language="javascript"><BR>function tanchu()<BR>{<BR> window.open("Untitled-5.html"); <BR>}<BR>script><BR><body><BR> <form id="form1" name="form1" method="post" action=""><BR> <label> <input type="submit" name="button" id="button" value="提交"<BR> onclick="tanchu()" /><BR> label> <label> <input type="text" name="textfield" id="textfield" /><BR> label><BR> form><BR></body><BR></html><BR>2.子页面代码：</P>
<P><html xmlns="http://www.w3.org/1999/xhtml"><BR><head><BR><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><BR><title>无标题文档title><BR>head><BR><script language="javascript"><BR>function aaa()<BR>{<BR> window.opener.document.getElementByIdx('textfield').value='123123123';<BR>}<BR>script><BR><body><BR> <form id="form1" name="form1" method="post" action=""><BR> <label> <input type="submit" name="button" id="button" value="提交"<BR> onclick="aaa()" /><BR> label><BR> form><BR></body><BR></html><BR>二、子页面是iframe框架中的页面情况<br><br>子页面要向父页面传值，只要在document前面加parent即可。 <BR>1.父页面代码：</P>
