Java 将jsp上输入的值获取到action类
当我在jsp中键入新内容,然后将列表提交给actionclass时,如何获取该值?目前,我可以从jsp提交到action类,并查看我在action中创建的新列表。但是我希望能够重新保存我在jsp中键入的值 员工对象类:Java 将jsp上输入的值获取到action类,java,jsp,input,struts,action,Java,Jsp,Input,Struts,Action,当我在jsp中键入新内容,然后将列表提交给actionclass时,如何获取该值?目前,我可以从jsp提交到action类,并查看我在action中创建的新列表。但是我希望能够重新保存我在jsp中键入的值 员工对象类: public class Employee { String empid; String empname; public String getEmpid() { return empid; }

这是怎么回事
第一步。。。
在action类中编写消息。。
示例--request.setAttribute(“消息”,“用户删除成功”) 第二步。。。 正在jsp页面中获取消息。。 范例-- 如果您正在搜索此请使用下面的示例 在JSP中:
<logic:iterate name="monthlyGainLossForm" property="ptcList" id="productTaxCat">
<html:hidden name="productTaxCat" property="ptcId" indexed="true" />
<html:hidden name="productTaxCat" property="ptcName" indexed="true" />
<html:hidden name="productTaxCat" property="ptcActive" indexed="true" />
<mf:tr>
<mf:td><bean:write name="productTaxCat" property="ptcName"/></mf:td>
<mf:td><bean:write name="productTaxCat" property="ptcActive"/></mf:td>
<mf:td><html:checkbox name="productTaxCat" property="msaPtcLtcGLType" styleClass="input" indexed="true"/></mf:td>
<mf:td><html:text name="productTaxCat" property="msaPtcLtcGLAmt" styleClass="label" style="width:100px;vertical-align:middle;" disabled="true" indexed="true"/></mf:td>
<mf:td><html:checkbox name="productTaxCat" property="msaMthlyStcGLType" styleClass="input" indexed="true"/></mf:td>
<mf:td><html:text name="productTaxCat" property="msaMthlyStcGLAmt" disabled="true" styleClass="label" style="width:100px;vertical-align:middle;" indexed="true"/></mf:td>
<mf:td><html:checkbox name="productTaxCat" property="nonMsaPtcGLType" styleClass="input" indexed="true"/></mf:td>
<mf:td><html:text name="productTaxCat" property="nonMsaPtcGLAmt" disabled="true" styleClass="label" style="width:100px;vertical-align:middle;" indexed="true"/></mf:td>
<mf:td><html:checkbox name="productTaxCat" property="nonMsaStcGLType" styleClass="input" indexed="true"/></mf:td>
<mf:td><html:text name="productTaxCat" property="nonMsaStcGLAmt" disabled="true" styleClass="label" style="width:100px;vertical-align:middle;" indexed="true"/></mf:td>
</mf:tr>
</logic:iterate>
在行动中:
for(int m = 0; m < monthGainLossForm.getPtcList().size(); m++) {
ProductTaxCat prodTaxCat = (ProductTaxCat)monthGainLossForm.getPtcList().get(m);
if(prodTaxCat.getMsaMthlyStcGLType()) {
selectedPtcTypeCounter++;
}
if(prodTaxCat.getMsaPtcLtcGLType()) {
selectedPtcTypeCounter++;
}
if(prodTaxCat.getNonMsaPtcGLType()) {
selectedPtcTypeCounter++;
}
if(prodTaxCat.getNonMsaStcGLType()) {
selectedPtcTypeCounter++;
}
}
for(int m=0;m
no,当我在jsp中键入bob、sally、sue等时,我希望将这些值返回到action类,以便在重新加载页面时提交时,我看到我在jsp上输入的内容,而不是默认值Show abt为bean创建对象并获取这些值
