Flex 3:文本输入的动态创建和绑定 [英] Flex 3: Dynamic creation and binding of textinput

问题描述

有没有人有关于如何创建动态数量的 TextInput 框并将在这些框中键入的每个文本绑定到标签的示例?例如，假设我有一个 XML 文件，它指定我需要 3 个 TextInput 框.然后 Flex 应该获取这些数据，创建 TextInput 框，为每个 TextInput 创建可绑定变量并创建一个标签来显示为每个 TextInput.我在解决这种情况时遇到的最大问题是如何绑定可变数量的数据.有什么想法吗?

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

该函数创建一对 textinput/label，其中 label.text 绑定到 textinput 中的数据.这应该是您代码的一个很好的起点.

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);
}
