Flex 3的：动态创建和TextInput结合 [英] Flex 3: Dynamic creation and binding of textinput

问题描述

有没有人对如何创建的TextInput 箱一个动态数字，让每个被键入这些框中的文字被绑定到标签的任何例子吗？例如，假设我有一个XML文件，该文件规定，我想3 的TextInput 框。那么Flex的要以此数据，创建的TextInput 箱，每个创建绑定变量的TextInput ，并创建一个标签来显示什么是被键入的每一个的TextInput 。我在遇到解决此方案最大的问题是如何将数据绑定的变量数量。任何想法？

Does anyone have any examples on how to create a dynamic number of TextInput boxes and have each of the text being typed in these boxes be bound to a label? For example, say I have an XML file that specifies that I want 3 TextInput boxes. Flex should then take this data, create the TextInput boxes, create bindable variables for each TextInput and create a label to display what is being typed for each TextInput. The biggest issue I'm having with solving this scenario is how to bind a variable amount of data. Any ideas?

推荐答案

这个函数创建一个对的TextInput /标签，其中label.text被绑定到数据的TextInput的。这应该是一个很好的起点为您的code。

This function creates a pair of textinput/label, where label.text is binded to data in textinput. This should be a good starting point for your code.

private function createTextFieldWithLabel ():void
{
    var tf:TextInput = new TextInput();
    var label:Label = new Label();
    var binding:ChangeWatcher = BindingUtils.bindProperty(label, "text", tf, "text");
    var hbox:HBox = new HBox();
    hbox.addChild(tf);
    hbox.addChild(label);
    addChild(hbox);
}
