<p>I am trying to use the $.getJSON function to return data. I have the following html file named page.html</p> <pre><code><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd "> <html xmlns=" http://www.w3.org/1999/xhtml "> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Request json test</title> <script src="http://code.jquery.com/jquery-1.7.2.min.js"></script> <script type="text/javascript"> $(document).ready(function(){ $("button").click(function(){ $.getJSON("json-data.php",function(result){ alert(result); }); }); }); </script> </head> <body> <button>Get JSON data</button> <div id="showdata"></div> </body> </html> </code></pre> <p>I also have the following PHP file named json-data.php:</p> <pre><code><?php //request data from the database //code here to connect to database and get the data you want /* Example JSON format { "item1": "I love jquery4u", "item2": "You love jQuery4u", "item3": "We love jQuery4u" } */ $item1 = "I love jquery4u"; $item2 = "You love jquery4u"; $item3 = "We love jquery4u"; //return in JSON format echo "{"; echo "item1: ", json_encode($item1), "\n"; echo "item2: ", json_encode($item2), "\n"; echo "item3: ", json_encode($item3), "\n"; echo "}"; ?> </code></pre> <p>I am only trying to use the alert function to see the data in the PHP file, however it does not work. Anyone know why?</p> <p>Thanks, Jim</p>

Guidance

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.
