}
i have few elements in my ArrayList list, and i want to show these elements in a select tag in my jsp. I have done it but the select tag is repeating itself as it is in the loop.I am not able to print the elements in a single select tag. Thanks in advance
你去：
out.println("<html><select>") ;
for(int i=0;i<list.size();i++)
{
out.println("<option>"+list.get(i)+"</option>");
}
out.println("</select></html>") ;
生成：
<html>
<select>
//loop begins here
<option> option1 </option>
<option> option2 </option>
....
<option> option n </option>
//loop ends here
</select>
</html>
每次迭代时，您都在添加html 和select标记。HTML 和 select 标签只需要创建一次。尝试这个
out.println("<html><select>");
System.out.println("items are");
for(int i=0;i<list.size();i++)
{
System.out.println(list.get(i));
out.println("<option>"+list.get(i)+"</option>");
}
out.println("</select></html>");
