我正在開發一個使用JSP和Servlets的示例Web應用程序,在此應用程序中,我已經在Servlet中設置了一些對象,我可以使用request.getAttribute("Object")
在JSP中檢索該值。這裏我想在JSP中迭代該數組的值。我怎麼能做到這一點,任何人都可以幫助我。如何檢索javascript/jsp中的Arraylist對象?
我的servlet代碼:
ArrayList<Performer> Performerobj=new ArrayList<Performer>();
ResultSet rst = stm1.executeQuery("some query");
while (rst.next())
{
Performer obj=new Performer();
obj.setProject(projectname);
obj.setCount(rst.getString("COUNT"));
obj.setDate(rst.getString("DATE"));
obj.setEmpid(rst.getString("empid"));
Performerobj.add(obj);
}
request.setAttribute("Performer", Performerobj);
Performer.java
public class Performer {
private String project;
private String empid;
private String date;
private String count;
public String getProject() {
return project;
}
public void setProject(String project) {
this.project = project;
}
/*setter and getter...... for all*/
Perform.jsp
<% List<Performer>obj1=List<Performer>)request.getAttribute("Performerobj"); %>
<script>
var obj=<%=obj1%>
for(obj object : list)
{
/*IS it correct way or how can i iterate*/
}
</script>
您是否收到任何錯誤?這裏是一個例子 - http://stackoverflow.com/questions/16397207/iterate-arraylist-in-jsp – 2015-03-13 10:49:41
在jsp中,我可以使用這個選項,但在java腳本中,我該如何使用該方法? – 2015-03-13 11:19:14
