<p>Ok, so I am fairly new to webdeveloping, so probably a silly question:</p> <p>I have this search form which does autocomplete for fooditems (gets values from a database column) and that works. Now when I press the submit button I want to load a block of code that displays the food-items' calories etc (also in the database on the same row as the food-item). </p> <p>How can I accomplish such a thing. I kno this is a fairly broad question, but what i am really asking is, how can I make a small part of my website reload when pressing the submit button and using the input given in the text field as a parameter of some kind.</p> <p>I don't need whole answers, just any tips getting to the right path would be greatly appreciated!</p> <p>here my code for the input and button:</p> <p>in head</p> <pre><code><script type="text/javascript" src="jquery.js"></script> <script> function ok(){ $.post("test.php", { name: "John", time: "2pm" }, function(data){ alert("Data Loaded: " + data); }); } </script> </code></pre> <p>in body:</p> <pre><code><form autocomplete="off"> <p> Food <label>:</label> <input type="text" name="food" id="food" / > </p> <input type="submit" id="submit" value="Submit" onclick="ok()" /> </form> </code></pre> <p>or:</p> <p>head: </p> <pre><code><script type="text/javascript" src="http://code.jquery.com/jquery-1.4.4.js"></script> <script> $("input[type='submit']").bind("click", function (event) { event.preventDefault(); // Stop a form from submitting $.post("/path/to/call", { /* data? */ }, function (data) { // Process return data here }); }); </script> </code></pre> <p>body:</p> <pre><code> <form autocomplete="off"> <p> Food <label>:</label> <input type="text" name="food" id="food" / > </p> <input type="submit" id="submit" value="Submit" /> </form> </code></pre>

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.
