Of particular interest to us is the <code>clipboardData</code> property of this event which enables clipboard access in non-ie browsers. In IE the equivalent is <code>window.clipboardData</code>, although this has a slightly different API.</p> <p>See resources section below.</p> <hr> <p><strong>The <code>handlepaste</code> function:</strong></p> <p>This function has two branches.</p> <p>The first checks for the existence of <code>event.clipboardData</code> and checks whether it's <code>types</code> property contains 'text/html' (<code>types</code> may be either a <code>DOMStringList</code> which is checked using the <code>contains</code> method, or a string which is checked using the <code>indexOf</code> method). If all of these conditions are fulfilled, then we proceed as in solution #1, except with 'text/html' instead of 'text/plain'. This currently works in Chrome and Firefox 22+.</p> <p>If this method is not supported (all other browsers), then we</p> <ol> <li>Save the element's contents to a <code>DocumentFragment</code></li> <li>Empty the element</li> <li>Call the <code>waitForPastedData</code> function</li> </ol> <hr> <p><strong>The <code>waitforpastedata</code> function:</strong></p> <p>This function first polls for the pasted data (once per 20ms), which is necessary because it doesn't appear straight away. When the data has appeared it:</p> <ol> <li>Saves the innerHTML of the editable div (which is now the pasted data) to a variable</li> <li>Restores the content saved in the DocumentFragment</li> <li>Calls the 'processPaste' function with the retrieved data</li> </ol> <hr> <p><strong>The <code>processpaste</code> function:</strong></p> <p>Does arbitrary things with the pasted data. In this case we just alert the data, you can do whatever you like. You will probably want to run the pasted data through some kind of data sanitising process.</p> <hr> <p><strong>Saving and restoring the cursor position</strong></p> <p>In a real sitution you would probably want to save the selection before, and restore it afterwards (<a href="https://stackoverflow.com/questions/1181700/set-cursor-position-on-contenteditable-div/3323835#3323835">Set cursor position on contentEditable &lt;div&gt;</a>). You could then insert the pasted data at the position the cursor was in when the user initiated the paste action.</p> <h1>Resources:</h1> <ul> <li>MDN paste event: <a href="https://developer.mozilla.org/en-US/docs/Web/Events/paste" rel="noreferrer">https://developer.mozilla.org/en-US/docs/Web/Events/paste</a></li> <li>MSDN clipboard: <a href="https://msdn.microsoft.com/en-us/library/ms535220(v=vs.85).aspx" rel="noreferrer">https://msdn.microsoft.com/en-us/library/ms535220(v=vs.85).aspx</a></li> <li>MDN DocumentFragment: <a href="https://developer.mozilla.org/en/docs/Web/API/DocumentFragment" rel="noreferrer">https://developer.mozilla.org/en/docs/Web/API/DocumentFragment</a></li> <li>MDN DomStringList: <a href="https://developer.mozilla.org/en/docs/Web/API/DOMStringList" rel="noreferrer">https://developer.mozilla.org/en/docs/Web/API/DOMStringList</a></li> </ul> <p>Thanks to Tim Down to suggesting the use of a DocumentFragment, and abligh for catching an error in Firefox due to the use of DOMStringList instead of a string for clipboardData.types</p>

    1. COInteresting. I thought I'd tried this in the past and it hadn't worked in some browser, but I'm sure you're right. I would definitely prefer moving the existing content into a `DocumentFragment` rather than using `innerHTML` for several reasons: first, you keep any existing event handlers; second, saving and restoring `innerHTML` is not guaranteed to create an identical copy of the previous DOM; third, you can then save the selection as a `Range` rather than having to faff around with adding marker elements or calculating text offsets (which is what you'd have to do if you used `innerHTML`).

    2. COAh, well that explains why my event handlers were disappearing! I might just add them back afterwards though, because extracting to a `documentFragment` is a pain in IE.

    3. COAnother problem with this approach is that the brief time where there is no content will be visible to user as a brief flash (haven't tested this but I'd be surprised if it wasn't true).

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
