Editor to share with you what are the ways of Flex3.0 data binding, 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!

Using Flex3.0 data binding to process data

Flex3.0 data binding is the process of connecting data from one object to another. It provides a convenient way to transfer data in an application.

AdobeFlex3 provides several ways to specify Flex3.0 data binding:

◆ uses curly braces ({}) syntax.

◆ uses ActionScript expressions in curly braces

◆ uses tags in MXML

◆ uses bindings in ActionScript

Use curly braces ({}) syntax

Flex3.0 data binding requires source attributes, target attributes, and trigger events. The trigger event table name is appropriate to copy data from the source to the destination. The following example shows a Text control that gets the data for the value property of the Hslider control. The property name in curly braces is the source property of the binding expression. When the value of the original property changes, Flex copies the current value of the source property mySlider.value to the target property, the text property of the Text control.

Examples

Use ActionScript expressions in curly braces

The binding expression in curly braces can be included in the ActionScript expression to send back a result. For example, you can use curly braces syntax for the following types of bindings:

◆ has a separate bindable attribute in curly braces

◆ uses string concatenation in curly braces, where the station is a bindable attribute

◆ 's calculation based on bindable attributes in curly braces

◆ uses conditional operations in curly braces to determine a bindable attribute

In the following example, each type of binding expression is used in the user interface.

Examples

{nameInput.text} Thisis {nameInput.text} {(Number (numberInput.text) asNumber) * 6x7} {(isMale.selected)? "Mr.": "Ms."} {nameInput.text} is all the content of this article entitled "what are the ways of Flex3.0 data binding?" Thank you for reading!
