1. The child page pops up when the parent page pops up through window.open
To transfer values from the child page to the parent page, just add window.opener in front of the document.
For example:
1. Parent page code:
Untitled document 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> onclick="tanchu ()" /><br> label> ;/body><br></html><br>2. Sub-page code: <br>
<br><html xmlns="http://www.w3.org/1999/xhtml"><br><head><br><meta http-equiv="Content-Type" content=" text/html; charset=utf-8" /></p><title>Untitled document title><p>head><br><script language="javascript"><br>function aaa() <br>{<br> window.opener.document.getElementByIdx('textfield').value='123123123';<br>}<br>script><br><body><br> "form1" name="form1" method="post" action=""><br> <label> <input type="submit" name="button" id="button" value="Submit"<BR> onclick="aaa()" /><br> label><br> form><br></body><br></html><br><br>Second, the sub-page is an iframe Page status in the frame <br><br><br> If the child page needs to pass the value to the parent page, just add parent in front of the document. <strong>1. Parent page code: </strong>
<br><html xmlns="http://www.w3.org/1999/xhtml"><br><head><br><meta http-equiv="Content-Type" content=" text/html; charset=utf-8" /></p><title>Untitled document title><p>head><br><body><br> <form id="form1" name= "form1" method="post" action=""><br> <iframe id="myiframe" src="Untitled-3.html">iframe><br> form><br></body><br></html><br>2. Sub-page code <br>
<br><html xmlns="http://www.w3.org/1999/xhtml"><br><head><br><meta http-equiv="Content-Type" content=" text/html; charset=utf-8" /><br><title>Untitled document title><br>head></p><script language="javascript"><p>function aa() <br>{ <br> var a=parent.document.getElementByIdx('textfield').value;<br> alert(a); <br>}<br>script><br><body><br> <form id="form1" name="form1" method="post" action=""><br> "Submit"</p></div><div class="nphpQianMsg"><div class="clear"></div></div><div class="nphpQianSheng"><span>Statement：</span><div>The content of this article is voluntarily contributed by netizens, and the copyright belongs to the original author.
