    <p>I got some progressbar Update Issues. What I like to do is, fire a ajax call which takes some time to complete and during the this call I'd like to fire ajax calls, set by an interval, to update my progressbar.</p> <p>Since I could not find a solution and only found the Browser's restriction, which would match here. It's always max 2 calls active.</p> <p>Still, my second call stays pending in Google Chrome, untill my first (main) call finished.</p> <p>EDIT: full jquery script</p> <pre><code>// update cars cache $('#cars_cache_update_run').bind('click', function(){ // remove button $(this).remove(); // hide import widgets $('#products_import_widget').css('display', 'none'); $('#vehicles_import_widget').css('display', 'none'); $('#orders_import_widget').css('display', 'none'); $('#test_data_widget').css('display', 'none'); // show blind $('#cars_cache_update_info').css('display', 'none'); $('#cars_cache_update_blind').css('display', 'inline'); var carsUpdateInterval = setInterval(function() { getImportState('http://localhost/index.php/import/import_state/cache_update', 'cars_import_progressbar'); }, 1000); // ajax request $.ajax({ url: "http://localhost/index.php/import/cars_cache", async : true, success: function(data){ $('#cars_cache_update_blind').css('display', 'none'); $('#cars_cache_update_success').css('display', 'inline'); clearInterval(carsUpdateInterval); }, error: function(thrownError){ $('#cars_cache_update_blind').css('display', 'none'); $('#cars_cache_update_error').css('display', 'inline'); $('#cars_cache_update_error_msg').html(thrownError); } }); }); function getImportState(url, id) { $.ajax({ url: url, success: function(data){ var json = $.parseJSON(data); $.each(json, function(i, item) { var progressbar_value = json[i]['state']; $( "#"+id ).progressbar({ value: progressbar_value }); }) } }); } </code></pre> <p>Another funny thing, if I call the interval request by $.get I'll get a strange error.. Working with Codeignitor Framework.</p> <pre><code>GET http://localhost/[object%20Object] 404 (Not Found) jquery.1.7.min.js:4 send jquery.1.7.min.js:4 f.extend.ajax jquery.1.7.min.js:4 f.(anonymous function) jquery.1.7.min.js:4 (anonymous function) </code></pre> <p>Many Thanks for your help already, been trying for hours now.. Maybe I'm just a noob.. Haha.</p> <p>rootless</p>

    2. COHow are you handling this on the serverside, as often times there can be issues with only request per session etc. when doing multiple ajax calls to the same backend.

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).
