webwork doubleselect 级联处理

项目: appfuse webwork1.8.2

实现的时候,参照http://loohost.com/thread-2396-1-1.html 进行开发,实现了级联功能

实例:

<ww:doubleselect label="getText('wapcontent.provider.name')"
   name="'wapcontentname'" list="providernames" listKey="top"
   doubleList="mobilemodelmap.get(top)"
   doubleName="'mobilemodeltype'"
   >
   </ww:doubleselect>

其中的name和doublrName 在action里,将作为对应的mapkey值,而listKey 会成为'wapcontentname'对应的值

至于关联的第二个对象的value值,将在自动构建的脚本中获得.

对应的界面自动生成的脚本如下":

wapcontentnameRedirect(0)
function wapcontentnameRedirect(x){

var wapcontentnameTemp=document.wapcontent.mobilemodeltype
//alert(wapcontentnameTemp);

wapcontentnameTemp.options[m]=null
//alert('eeeee');

alert(wapcontentnameGroup[x].length);
for(i=0;i<wapcontentnameGroup[x].length;i++){
wapcontentnameTemp.options[i]=new Option(wapcontentnameGroup[x][i].text,wapcontentnameGroup[x][i].value)
}

if(wapcontentnameTemp.options.length>0)
wapcontentnameTemp.options[0].selected=true
wapcontentnameTemp.refesh();
alert('eeeee');
}
//-->

function wapcontent_validate_actual(){
