Editor to share with you what Flex data binding methods are, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

On several bindings of Flex

In Flex applications, Flex data binding is actually accomplished with the help of event mechanism. when the target uses Flex data binding, the target object listens for a fixed event of the data source object. When the data source changes, the data source dispatches a change event to notify the target object to update the data. In the actual development, we do not need to pay attention to the specific implementation process, this process will be completed automatically by Flash/Flex.

In Flex, there are four main ways of Flex data binding, namely: "{}" binding expression, [Bindable] binding symbol, label and BindingUtils dynamic binding. The following four Flex data binding methods are described in detail.

Flex data binding * *, using {} binding

The second kind of Flex data binding, binding

The third type of Flex data binding, using the BindingUtils utility class

BindingUtils.bindProperty (target, "targetProperty", source, "sourceProperty")

◆ target:Object- goal

◆ targetProperty: target attribute, String type

◆ source:Object- binding source

◆ sourceProperty: source attribute, String type

BindingUtils.bindProperty (labelTarget, "text", inputSource, "text"); these are all the contents of the article "what are the ways of Flex data binding?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
