我希望有人可以帮助我......
我正在尝试为问卷模块构建动态表单。在以前的一些帖子的基础上，我使用类似于问题“How to generate a form(<mx:form>) dynamically in flex?”的过程，我已经设法证明了扩展XML以包括日历，组合框等的事实。
我的问题是现在需要从ArrayCollection而不是从xml文件中获取数据。我想循环通过AC，其中type =“text”呈现textinput字段，其中type =“calendar”呈现日历等等。
到目前为止，我的代码只是查看textinput字段（对所有评论都很抱歉;）是： -
[Bindable]
public var AC:ArrayCollection = new ArrayCollection( [
{type:'text', direction:'horizontal', tooltip:'test tooltip', label:'my textbox label', id:'1'},
{type:'text', direction:'horizontal', tooltip:'another tooltip', label:'another label', id:'2'}
]);
private function init():void
{
var form:Form = new Form();
for each(var elements:String in AC)
{
switch( elements.@type.toString())
{
case "text":
var fi:FormItem = new FormItem();
// fi.toolTip = elements.tooltip.toString();
// fi.required = getglobalprofile.required.toString();
// fi.direction = getglobalprofileb[i].@direction;
var li:Label = new Label();
// li.text = getglobalprofileb[i].@label;
// li.width = 100;
var ti:TextInput = new TextInput();
ti.text = "test";
ti.width = 200;
form.addChild(fi);
fi.addChild(li);
fi.addChild(ti);
// break;
}
}
this.addChild( form);
}
]]>
</mx:Script>
<!-- Data grid added just to check that AC getting data-->
<mx:DataGrid id="profile" selectedIndex="1" dataProvider="{AC}" width="100%" height="50%" />
<mx:Form id="form" name="form">
</mx:Form>
如果您对工作的xml版本感兴趣（仅渲染），请告诉我，我也会发布此内容
答案 0 :(得分：0)
我找到了这个问题的第一部分的答案，即使用RO调用向DB提交简单请求来呈现表单。
下一个问题是当我不“知道”字段ID，有多少字段或字段类型时，如何保存表单.........
另一篇文章暗示了！
希望这对某人有用。
