    <p>I've recently completed something in jQuery after having to change it and I kind of feel dirty. But let me explain.</p> <p>My first attempt was simple, on page load I looped through and created all the bindings such as below I have attached below. This allows the bindings to happen at one time.</p> <pre><code>var flyouts = $('.comment[data-flyout]'); $.each(flyouts,function(){ var textarea = $(this).find('textarea'); var flyout = $(this).find('.write-comment__flyouts'); var addFile= $(this).find('[data-flyout=btn-file]'); textarea.click(function(){ flyout.addClass('open'); }); addFile.click(function(){ flyout.addClass('open').removeClass('open-link').toggleClass('open-files'); }); }); </code></pre> <p>Because of the project I've had to switch over to using jQuery's .on() function because content is dynamic. The problem there is that I can't create all the bindings at one time and instead, whenever there is a 'click' or a 'focus' have to navigate the DOM from that point up to a parent object and back down. Since I can't figure out a way to create the bindings at one point. Below is the same functionality as above.</p> <pre><code> var wrapper = $('.flyout-holder'); var textarea = 'textarea'; var flyout = '.write-comment__flyouts'; var addFile = '[data-flyout=btn-file]'; var parent = '.write-comment[data-flyout]'; wrapper.on('click',textarea,(function(){ $(this).closest(parent).find(flyout).addClass('open'); }); wrapper.on('click',addFile,function(){ $(this).closest(parent).find(flyout).addClass('open').removeClass('open-link').toggleClass('open-files'); }); </code></pre> <p>So I now have to go find the related object that I want to do something to every single time there's an event. Versus hooking it all up in the beginning. Is there a better way to do this when working with jQuery's .on() function?</p>

    1. COYou can always use `body` as the parent.

    3. COThe wrapper variable contains the common parent between all of these (the `$('.flyout-holder')`. That way it won't have to bubble up to `body` which isn't recommended.

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.
