jsp上有两个下拉列表框combox1对应变量trywmcsx, combox2对应变量trzdbhsx,其中的数据是从db中取得的,但其内容不能相同!
validation.xml写法:
<form name= "/jbbhszqt ">
<field property= "trywmcsx " depends= "required ">
<msg name= "required " key= "validate.required.err "/>
<arg0 key= "tr.ywmc "/>
</field>
<field property= "trzdbhsx " depends= "required ">
<msg name= "required " key= "validate.required.err "/>
<arg0 key= "tr.zdbh "/>
</field>
<field property= "trywmcsx " depends= "twofields ">
<msg name= "twofields " key= "validate.twofields.err "/>
<arg0 key= "tr.ywmc "/>
<arg1 key= "tr.zdbh "/>
<var>
<var-name> secondproperty </var-name>
<var-value> trzdbhsx </var-value>
</var>
</field>
</form>
validator-rules.xml写法
<validator name= "twofields " classname= "seerp.common.validator.validateactionform "
method= "validatetwofields "
methodparams= "java.lang.object,
org.apache.commons.validator.validatoraction,
org.apache.commons.validator.field,
org.apache.struts.action.actionerrors,
javax.servlet.http.httpservletrequest "
depends= " " msg= "validate.twofields.err ">
<javascript> <![cdata[
function validatetwofields（form) {
var bvalid = true;
var focusfield = null;
var i = 0;
var fields = new array（);
otwofields = new twofields（);
for （x in otwofields) {
var field = form[otwofields[x][0]];
var secondfield = form[otwofields[x][2]（ "secondproperty ")];
if （field.type == 'text ' ¦ ¦
field.type == 'textarea ' ¦ ¦
field.type == 'select-one ' ¦ ¦
field.type == 'radio ' ¦ ¦
field.type == 'password ') {
var value;
var secondvalue;
// get field 's value
if （field.type == "select-one ") {
var si = field.selectedindex;
value = field.options[si].value;
secondvalue = secondfield.options[si].value;
} else {
value = field.value;
secondvalue = secondfield.value;
}
if （value == secondvalue) {
if （i == 0) {
focusfield = field;
}
fields[i++] = otwofields[x][1];
bvalid = false;
}
}
}
if （fields.length > 0) {
focusfield.focus（);
alert（fields.join（ '\n '));
}
return bvalid;
}
string.prototype.lenb = function（) {
return this.replace（/[^\x00-\xff]/g, "** ").length;
}]]> </javascript>
</validator>
vilidator java文件:
/**

* @param object
* object
* @param validatoraction
* validatoraction
* @param field

*/
public static boolean validatetwofields（object bean, validatoraction va,
field field, actionerrors errors, httpservletrequest request) {
log.debug（ "start ");
string value = validatorutil
.getvalueasstring（bean, field.getproperty（));
string sproperty2 = field.getvarvalue（ "secondproperty ");
string value2 = validatorutil.getvalueasstring（bean, sproperty2);
if （!genericvalidator.isblankornull（value)) {
try {

request, va, field));
}
} catch （exception e) {
e.printstacktrace（);
}
}
log.debug（ "end ");
return errors.isempty（);
}
jsp写法:
<html:javascript formname= "/jbbhszqt " method= "validatejbbhszqt " dynamicjavascript= "true " staticjavascript= "false " />
1> 进行客户端验证的时候,即使内容不同,也弹出错误信息!
2> 在进行服务器端验证的时候,会出现以下错误:
2007/01/05 09:48:42.273 [error] org.apache.catalina.core.containerbase.[catalina].[localhost].[/seerp].[action].invoke:servlet.service（) for servlet action threw exception
javax.servlet.jsp.jspexception: failed to obtain specified collection

请高手帮忙!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
