如何在 flex 中动态生成表单(<mx:form>)? [英] How to generate a form(&lt;mx:form&gt;) dynamically in flex?

问题描述

我需要从我从 httpservice 获取的 xml 文件生成一个 mx:form.

I need to generate a mx:form from an xml file that I am getting from httpservice.

此外，我需要预先填写从表单本身获得的数据.

Also I need to prefill the data that I am getting from the form itself.

谁能给我一个示例代码?

Can someone give me a sample code?

推荐答案

显然您必须对此进行扩展，但这就是我构建动态表单的方式..

You would have to expand on this obviously, but this is how I would go about building a dynamic form..

            import mx.controls.TextInput;
        import mx.containers.FormItem;
        import mx.containers.Form;
        private var fxml:XML = 
        <form>
            <fields>
                <field type="text" label="name" default="gary"/>
                <field type="text" label="surname" default="benade"/>
            </fields>
        </form>

        private function init():void
        {
            var form:Form = new Form();
            form.setStyle("backgroundColor", 0xFFFFFF);
            for each( var xml:XML in fxml..field)
            { 
                switch( [e-mail]())
                {
                    case "text":
                        var fi:FormItem = new FormItem();
                        fi.label = xml.@label;
                        var ti:TextInput = new TextInput();
                        ti.text = [e-mail]();
                        fi.addChild( ti);                           
                        form.addChild( fi);
                    break;
                    case "int":
                    break;
                }
            }               
            this.addChild( form);
        }
