Body
<p>I'm new to using javascript and have come up against a bit of a wall where I was looking for code to duplicate a DIV. I found the following code:</p> <pre><code><html> <body> <form name="myform"> <input type="button" value="Click here" onclick="duplicate()"> <div id="original"> duplicate EVERYTHING INSIDE THIS DIV </div> <div id="duplicater"> duplicate EVERYTHING INSIDE THIS DIV <input type="button" value="Remove Div" onclick="this.parentNode.style.display = 'none'"> </div> <script> var i = 0; var original = document.getElementById('duplicater'); function duplicate() { var clone = original.cloneNode(true); // "deep" clone clone.id = "duplicater" + ++i; // or clone.id = ""; if the divs don't need an ID original.parentNode.appendChild(clone); } </script> </body> </html> </code></pre> <p>This works quite well. I added a Remove Div button so if the user decided they added one Div too many they would have the option to remove it. However, in testing I found if the user Remove Div all the way back to the first Div, any further Duplicate Div does not display. So the user would have to restart the page. To resolve this I tried to include an IF...ELSE.</p> <pre><code><html> <body> <form name="myform"> <input type="button" value="Click here" onclick="duplicate()"> <div id="original"> duplicate EVERYTHING INSIDE THIS DIV </div> <div id="duplicater"> duplicate EVERYTHING INSIDE THIS DIV <input type="button" value="Remove Div" onclick="this.parentNode.style.display = 'none'"> </div> <script> var i = 0; var original = document.getElementById('duplicater'); function duplicate() { if (document.getElementById("duplicater")=="none") { document.getElementById("duplicater")=""; } else { var clone = original.cloneNode(true); // "deep" clone clone.id = "duplicater" + ++i; // or clone.id = ""; if the divs don't need an ID original.parentNode.appendChild(clone); } } </script> </body> </html> </code></pre> <p>However, this does not work. I fully admit to being no coding guru and wouldn't be surprised if it is a simply syntax issue, but any points with this would be greatfully accepted.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
