    <p>I'm working with some AJAX calls, which connect properly, however if I attempt to use a ternary operator in the initialization of the call, the operator does not set properly. Specifically, I'm trying to dynamically set the async parameter. The AJAX call refuses to accept the ternary version of the async unless it's specified beforehand. This is specific to Firefox. Here's an example:</p> <p>Server receives the async call as true, regardless if I specify the <code>async = false;</code>.</p> <pre><code>function(url, type, async) { $.ajax({ url: url, type: type, async: async ? async : true }); } </code></pre> <p>Works correctly:</p> <pre><code>function(url, type, async) { var async = async ? async : true; $.ajax({ url: url, type: type, async: async }); } </code></pre> <p>Although the code is working when I specify it beforehand, I do not understand why a ternary operator won't work in this situation. I would love an explanation as to why it is required to be specified beforehand and not in the call itself.</p> <p>Thank you, Ben</p>

    1. COThe `? :` cannot reliably be used as in "if the argument is given" as there can be falsy values being passed explicitly (especially in the case of booleans).

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.
