    <p>I have the following jQuery Ajax code, and it would seem (unless I've misunderstood the problem) that without defining the <code>page</code> variable within the <code>$("#imgNum").change(function(){});</code>, the ajax call following the function will not fire.</p> <p>Since the <code>page</code> variable is set based on when a button is clicked (which fire's its own ajax call), I'm wondering if there is a way of setting <code>page</code> to be equal to the last value it was set at? Unless there is another way of saving this value to call on it, and refreshing it every time a certain function is performed?</p> <p><strong>The jQuery:</strong></p> <pre><code>function loadData(page, value){ loading_show(); gallery_hide(); $.ajax ({ type: "GET", url: "new_arrivals_data.php", data: {page:page, imgs:value}, success: function(msg) { gallery_show(); $("#gallery_container").ajaxComplete(function(event, request, settings) { gallery_show(); $("#gallery_container").html(msg); }); }, error: function(jqXHR, textStatus, errorThrown) { // Tell the human that something broke. }, complete: function() { // This is always called regardless of success or failure. loading_hide(); } }); } loadData(1); // For first time page load default results $('#gallery_container .pagination li.active').live('click',function(){ var page = $(this).attr('p'); loadData(page); }); $('#go_btn').live('click',function(){ var page = parseInt($('.goto').val()); var no_of_pages = parseInt($('.total').attr('a')); if(page != 0 &amp;&amp; page &lt;= no_of_pages){ loadData(page); }else{ alert('Enter a PAGE between 1 and '+no_of_pages); $('.goto').val("").focus(); return false; } }); $("#imgNum").change(function(){ var sel = $(this); var value = sel.val(); //THIS IS WHERE I WANT TO DEFINE THE PAGE BASED ON IT'S MOST RECENT VALUE var page = ?; loadData(page, value); }) //You should store the current selected option in a cookie //For the sake of the example i'll set the default permanently to 12 var imgNum_selected = 16; //set the initial selected option and trigger the event $("#imgNum [value='"+imgNum_selected+"']").prop("selected","selected").change(); </code></pre> <p>Would this be possible to do by saving the current value in a cookie which is reserved whenever the value is changed? How do you store a value in a cookie, and then retrieve it?</p>

    2. CO@K.B Well I would be more than happy to clear it up. What don't you understand? Basically, there are three jQuery events that can trigger the Ajax call. The last one needs to have the `page` variable defined, but being that `page` is only defined when something is clicked, I don't know how to pass what was the previously set value for `page`, as the current value for `page`. Does that make more sense?

    3. COWell either you will have to make the page variable as global variable or save it somewhere in DOM and load in imgnum.

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.
