    text
    copied!<p>I had a requirement to copy all fields from one form to another similar form. So instead of copying field by field I wrote a routine, form2form, using jQuery.</p> <pre><code>function form2form(aF1, aF2) { var selection = "#" + aF1 + " .copy"; $(selection).each(function() { document.forms[aF2].elements[$(this).attr('name')].value = $(this).val(); }); } </code></pre> <p>the routine works. The routine requires that in input form field have a class of copy otherwise I don't know how to get all fields in the form. ("#form :input") skips the radio button and select fields.</p> <p>So my questions are.</p> <p>Is there a built in function so I didn't need this? Is there a better way to write the selection? How do I modify the routine not to need the class. Can I pass form objects rather then the form name as a text? Is there a better way in general?</p> <p>this is a full page that works:</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt; &lt;title&gt;test form2form in jQuery&lt;/title&gt; &lt;script type="text/javascript" src="../scripts/jquery.js"&gt;&lt;/script&gt;&lt;/head&gt; &lt;script type="text/javascript"&gt; function form2form(aF1, aF2) { var selection = "#" + aF1 + " .copy"; $(selection).each(function() { document.forms[aF2].elements[$(this).attr('name')].value = $(this).val(); }); } function testform2form () { form2form ('form1', 'form2' ); } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;h3&gt;Copy form to form&lt;/h3&gt; &lt;form id="form1" name="form1"&gt; form1: f1 &lt;input type="text" name="f1" id="f1" class="copy" value="from A"/&gt; f2 &lt;input type="text" name="f2" id="f2" class="copy" value="from B" /&gt; &lt;select name="fruit" id="fruit" class="copy" &gt; &lt;option value="valApple" selected="selected"&gt;Apple&lt;/option&gt; &lt;option value="valOrange"&gt;Orange&lt;/option&gt; &lt;/select&gt; &lt;/form&gt; &lt;form id="form2" name="form2"&gt; form1: f1 &lt;input type="text" name="f1" id="f1" class="copy" value="target A" /&gt; f2 &lt;input type="text" name="f2" id="f2" class="copy" value="target B" /&gt; &lt;select name="fruit" id="fruit" class="copy" &gt; &lt;option value="valApple"&gt;Apple&lt;/option&gt; &lt;option value="valOrange" selected="selected"&gt;Orange&lt;/option&gt; &lt;/select&gt; &lt;/form&gt; &lt;p&gt;&lt;a href="#" onclick="testform2form()"&gt;Copy Form to Form (form2form)&lt;/a&gt;&lt;/p&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>
