Introduction

When working with jQuery UI's resizable feature, a common challenge developers face is how to pass variables from the resize event to the stop event. This can be particularly useful when you want to maintain state or carry over information during the resizing process. In this guide, we will discuss how to achieve this effectively using two different methods that cater to different scenarios.

Understanding the Problem

In the context of jQuery UI's resizable method, when you create a resizable element with the following code:

The variable blabla is contained within the resize function's scope. This means that it's not accessible in the stop function, which can lead to disappointment when trying to utilize its value after resizing. So, how do you effectively "unhide" this variable?

Solutions to Pass Variable Between Events

To share variables between the resize and stop events in jQuery UI, here are two effective methods:

Method 1: Declare the Variable Externally

One straightforward approach is to declare the variable outside of both the resize and stop functions. Here's how you can do it:

Pros: Easy to implement and understand.

Cons: If you have multiple instances of resizable elements, they will all share the same value of blabla, which may not be appropriate for your needs.

Method 2: Using jQuery's Data Storage

If you require each instance of the resizable to maintain its own state for the variable, consider using jQuery's data storage. You can attach custom properties to the jQuery object like this:

Benefits of This Method:

Each resizable instance holds its own value of blabla, preventing conflicts.

Ties the data to the element even if the resizable plugin is destroyed.

Conclusion

In conclusion, passing variables between events in jQuery UI can be accomplished in two main ways. You can either declare the variable externally, which is great for single instances, or you can utilize jQuery's data storage for multiple instances to keep things organized. Choose the method that best fits your project needs, and watch your jQuery UI elements work seamlessly together. Happy coding!
