flex中动态显示数据

思路：

    先定义一个空容器，然后再用actionscript语言往容器中添加：如访谈里面的例子：

protected function ftyyFindAllHandler(event:ResultEvent):void{

    _gzyy = event.result as ArrayCollection;

    if(_gzyy.length>0)

    for(var i:int=0;i<_gzyy.length;i++){

var m:GzyyModel=_gzyy.getItemAt(i) as GzyyModel;

var checkbox:CheckBox=new CheckBox();

checkbox.label=m.gzyymc;

checkbox.name=m.gzyym;

_checkList.addItem(checkbox);

gzyyGroup.addElement(checkbox);

}

}

效果：

还有一个例子：

[Bindable]

public var _data:ArrayCollection=new ArrayCollection();

protected function btn_add_clickHandler(event:MouseEvent):void

{

if(checkData())

{

var model:JxjModel=new JxjModel();

model.jxjmcm=ddl_jxjmc.selectedItem.jxjmcm;

model.jxjmc=ddl_jxjmc.selectedItem.jxjmc;

model.bzwh=StringUtil.trim(txtipt_bzwh.text);

model.bzrq=StringUtil.trim(datefld_jxjrq.text);

model.zzje=StringUtil.trim(txtipt_zzje.text);

model.bzsm=StringUtil.trim(txtipt_bzsm.text);

model.jxjdjm=ddl_jxjdj.selectedItem.jxjdjm;

model.jxjdjmc=ddl_jxjdj.selectedItem.jxjdjmc;

model.jxjlxm=ddl_jxjlx.selectedItem.jxjlxm;

model.jxjlxmc=ddl_jxjlx.selectedItem.jxjlxmc;

model.fbryxsh=YhModel._cjyxsh;

model.fbrzgh=YhModel._yhh;

model.yxsh=queryView.ddl_yxs.selectedItem.yxsh;

model.yxsjc=queryView.ddl_yxs.selectedItem.yxsjc;

model.zyh=queryView.ddl_zy.selectedItem.zyh;

model.bh=queryView.ddl_bj.selectedItem.bh;

model.xh=queryView._obj.xh; 

model.nj=queryView._obj.nj;

//级联表中字段

model.bjmc=queryView.ddl_bj.selectedItem.bjmc;

model.xm=queryView.btn_xzxs.label;

_data.addItem(model);

if(btn_submit.enabled==false)

btn_submit.enabled=true;

queryView.clearXs();

}

}

  variableRowHeight="true" itemDoubleClick="dg_itemDoubleClickHandler(event)" doubleClickEnabled="true"  >

效果：
