如何在Struts2

Question

在JSP選擇標籤指定選擇標籤的列表關鍵屬性多個值是含計劃的對象列表

這裏是一個計劃類

public class Plan { 

    private String packageId; 
    private String packageName; 
    private String price; 

    public String getPackageId() { 
     return packageId; 
    } 
    public void setPackageId(String packageId) { 
     this.packageId = packageId; 
    } 
    public String getPackageName() { 
     return packageName; 
    } 
    public void setPackageName(String packageName) { 
     this.packageName = packageName; 
    } 

    public String getPrice() { 
     return price; 
    } 
    public void setPrice(String price) { 
     this.price = price; 
    } 
} 

<s:select theme="simple" list="%{#request.packageList}" listKey="packageId" 
    listValue="packageName" headerKey="0" headerValue="--Select--" 
    name="packageID" class="dropdowm" id="packageID" /> 

現在我想listkey to have multiple values separated by comma like(packageId,price)

我該如何做到這一點？

Answer 1

在關鍵屬性只需指定它：

<s:select theme = "simple" 
      list = "%{#request.packageList}" 
     listKey = "packageId + ',' + price" 
     listValue = "packageName" 
     headerKey = "0" 
    headerValue = "--Select--" 
      name = "myNewCustomKey" 
     cssClass = "dropdowm" 
      id = "packageID" /> 

和（如果你使用的是最新的版本是不）在Struts標籤使用cssClass代替class。
