    <p>This is my first post so I hope I am not violating any rules. I have searched quite extensively, but possibly may have not looked for the correct terms that I am looking to resolve. </p> <p>At any rate, my problem is this: I have a table generated with a list of items, the left-most column has a button when clicked calls an ajax Post and or load function to query the history of the item and list it below the table. This works in its true sense of the expected result, however, reviewing the console through FireBug, subsequent clicks on buttons in the list result in the doubling of posts. ie. 1st click shows 1 console event, 2nd click shows 2 console events, 3rd click shows 4 console events, and so on. this continues until I select a different location and the count resets. </p> <p>The below is what I see in the console. This presents a problem with timing as each subsequent post takes longer. </p> <blockquote> <p>clicking the hist-tag button 5365</p> </blockquote> <pre><code>&gt;GET http://localhost/digipens/query.php?rec_id=5365 </code></pre> <blockquote> <p>clicking the hist-tag button 5365</p> </blockquote> <pre><code>&gt;GET http://localhost/digipens/query.php?rec_id=5365 </code></pre> <blockquote> <p>clicking the hist-tag button 5365</p> </blockquote> <pre><code>&gt;GET http://localhost/digipens/query.php?rec_id=5365 </code></pre> <blockquote> <p>clicking the hist-tag button 5365</p> </blockquote> <pre><code>&gt;GET http://localhost/digipens/query.php?rec_id=5365 </code></pre> <p>code:</p> <pre><code>$('.hist-tag').click(function(){ var ID=$(this).closest('tr').attr('id') itemid = $("#itemid_input_"+ID).val(); dataString = '?rec_id='+ID; $('#item_hist').load('query.php' + dataString); }); </code></pre> <p>Any ideas or different ways to accomplish the same goal would be excellent. </p> <p>Thanks!</p>

    1. COWhat does your html look like before and after your click the button? Hint: the relevant parts would center around the #item_hist elements.

    2. COon the main page the code before and after is just a div. <div id="item_hist"></div> as i mentioned in the OP, i do get the expected results ie. a listing of the items history from the desired table, however the unexpected behaviour is the doubling up of posts. if i click 4 different items, the 4th item i click will result in a post that issues 8 times...

    3. COtry doing an alert($('#item_hist').length); before your .load and see what you get.

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.
