Within my data object for the AJAX request, it is structured like this:
data: {
someVariable: []
}
However, upon initiating the AJAX call, I observe that someVariable is not included in the POST data being sent.
Sending an empty array through an ajax call may not be possible. It is recommended to devise your own workaround, such as passing an array with an empty string [''] and implementing special case handling on the server side.
After reviewing a bug report in the jQuery bug tracker, it was noted:
The issue arises from the inability to serialize an empty array in a way that is logical for x-www-form-urlencoded format. The value foo[bar]= could be interpreted as an empty array, empty string, empty object, or null/undefined depending on how the backend processes it. Since there is no definitive correct way of serialization, and most backends default to interpreting it as an "empty string", this disrupts traditional functionality (as discussed in a forum thread). As a result, I have flagged this to block version 1.6 so it can be reverted to its previous behavior.
As a solution,
This limitation stems from javascript itself
Instead, you can create a placeholder for an empty array by wrapping it in quotes, like '[]', and then interpret that as a new empty array on the server side.
