<html:optionsCollection />标签与LabelValueBean使用方法。

1，在jsp页面上引用：

<html:select property=”bankno” styleId=”bankno”  styleClass=”nputstyle2″  onchange=”doChgBankNo(this);” alt=”search”> <html:optionsCollection name=”bnDictionary” property=”bankNoList”/> < /html:select>

这段引用的（<html:optionsCollection name=”bnDictionary” property=”bankNoList”/>）name=bnDictionary是通过userBean进行定义的

<jsp:useBean id=”bnDictionary” scope=”application”></jsp:useBean>

2，后台java代码

bankNoList 为DictionaryBean 这个类下面的属性，返回的结果为list，list里面的值为LabelValueBean

public List getBankNoList(){ Map childMap = getChildDicMap(parentKey); List values; if (childMap == null){ values = new ArrayList(); }else { values = new ArrayList(childMap.size()-1); } List set = Utils.getOrderedList(childMap, new Dictionary.DictionaryComporator()); values.add(new LabelValueBean(DictionaryConstants.PLEASE_SELECT, “”)); for (Iterator it = set.iterator(); it.hasNext();) { Dictionary dictionary = (Dictionary)it.next(); String value = dictionary.getKeyValue(); if (“#”.equals(value)) continue; String label = dictionary.getKeyCaption(); values.add(new LabelValueBean(label, value)); } return values;           }

3，在js中获取这个html:optionsCollection 里面的值

function doChgBankNo(obj) {

var selectText = obj.options[obj.selectedIndex].text;//获取lable       var selectValue = obj.options[obj.selectedIndex].value;//获取value

}
