jQuery loaded dialog AJAX 'done' catch echoed result

耗尽温柔 提交于 2019-12-12 03:49:24
问题 I have a page where I use load to load a dialog box. From that dialog box, I have jQuery in there that posts an ajax request to a PHP script. This all works fine. From the PHP I echo out the result and attempt to catch that on the done callback from this loaded dialog - but its not working. It updates the database, but I can't catch the echo. This works elsewhere in my site, but I can't get it working here. I think it might have something to do with the fact that this is coming from a 'loaded

问题 I am on server side Node.js and somehow caught up in the callbacks. I use the following function to insert Data in the Table with the mysql pkg: connection.query('INSERT INTO tableName SET ?', post, function(err, result) { if (err) { if (err.code === 'ER_DUP_ENTRY') { } else { throw err; } } }); I want to log how many duplicate entries are there without stoping the loop which calls this above function by an $.each. It says here that i have 3 possibilities: throw, callbacks and EventEmitter.

Rails - Access AJAX Triggering Element in Callback

别等时光非礼了梦想. 提交于 2019-12-11 23:58:16
问题 I have a view, say show.js.erb. And I have a link in another view such that link_to "MyLink", my_object_path, :remote => true successfully returns the show.js.erb view. My question is, from within that view, is there any way to access the element that triggered the AJAX call without having to resort to generating an id specific to individual elements a la ... I want to be able to use this view callback to open a small dialog next to whatever element was clicked on, but I can't seem to find a

Has jQuery an 'animating'-event?

二次信任 提交于 2019-12-11 18:48:11
问题 Has jQuery an animating -event (not :animated )? Something like step, but as extra method/event? Currently I trigger a custom event in each animations step-function: $('.foo').animate({property: 'value'}, { step: function(now, fx){ $(this).trigger('animating', [now, fx]) } }); $('.foo').on('animating', function(e, now, fx){ // do what you want }); I think there's somewhere in the wild assuredly a better solution. Any ideas/approaches? Update I've written a (of course not awesome) special

jQuery callback on img src replacement?

非 Y 不嫁゛ 提交于 2019-12-11 04:47:10
问题 What I am trying to do is to change an image on my webpage when the user mouses over a thumbnail of it. It is easy for me to do it this was because the thumbnail src only has 'tn_' appended to the filename and is otherwise identical. The problem I'm having is that when I switch the src on the image the attr function returns the img dom element almost instantly while the image itself does not change until the new image loads. I want to have some sort of a callback, so that I can either change

jquery execute function when two conditions are met

问题 I need to execute a specific function mvFinishItUp() when two conditions are met. More specifically, one condition is the callback success of a $.ajax the other is a normal flow of the code until it reaches the function. Kinda of this: $.ajax({ url: mv_finalUrl, success: function (data) { mvFinishItUp(data); }, dataType: 'html' }); /* here a lot more code, with animations and some delays */ mvFinishItUp(data) { /* My function code */ /* But this code must only run after it has been called via
