如何在jsp中创建菜单栏 [英] How to create a menu bar in jsp

问题描述

我想知道如何在jsp中创建菜单栏，是否有任何编码要在.java文件中完成，因为我我是jsp的新手，如果有人可以指导我，我会很高兴.....

解决方案

创建具有预定义值的数组
 
 String [] myArray = {option1，option2，option3}; 
创建getter和setter 
 
 public String [] getMyArray（）{
 return myArray; 
} 
 public void setMyArray（String [] myArray）{
 this.myArray = myArray; 
} 
然后创建选择下拉列表并遍历你的数组，你可以像这样使用Struts2标签
 
 <  选择 >  
 <   s：iterator     value   =  myArray >  
 < span class =code-keyword><  选项    value   = < s：property /> >  <   s：property /  >  <   / option  >  <！ -    打印出迭代器的当前值   - >   
 <   / s：iterator  >  
 <   / select  >  

Hi,

I would like to know how to create a menu bar in jsp, and are there any coding to be done in .java file, because i am new to jsp and i would be glad if someone can guide me through.....

解决方案

Create array with predefined values

String[] myArray = {"option1", "option2", "option3"};
Create getters and setters

public String[] getMyArray() {
    return myArray;
}
public void setMyArray(String[] myArray) {
    this.myArray = myArray;
}
Then create select dropdown and iterate through your array, you can use Struts2 tags like this

<select>
    <s:iterator value="myArray">
        <option value="<s:property/>"><s:property/></option> <!-- This prints out current value of the iterator -->
    </s:iterator>
</select>
