根据下拉菜单的值确定action值

Question

思路有点乱
直接用JS判断要转到那个页上，
然后再设置action的值

Answer 1

能不能告诉我怎么打代码，我打进去好像不行吗~  <script language="javascript">     var   groups=document.search.zone.options.length;   
  var   group=new   Array(groups);  
  for   (i=0;   i<groups;   i++)   
  group[i]=new   Array();   
    
  group[0][0]=new   Option("请选择范围","   ");   
    
  group[1][0]=new   Option("类别","类别");   
  group[1][1]=new   Option("主题","主题");   
  group[1][2]=new   Option("标题","标题");   
  group[1][3]=new   Option("内容","内容");   
    
  group[2][0]=new   Option("类别","类别");   
  group[2][1]=new   Option("主题","主题");   
  group[2][2]=new   Option("名称","名称"); 
  group[2][3]=new   Option("说明","说明"); 
  
  group[3][0]=new   Option("歌手","歌手");   
  group[3][1]=new   Option("专辑","专辑");   
  group[3][2]=new   Option("歌名","歌名"); 
  group[3][3]=new   Option("备注","备注"); 
    
  var   temp=document.search.type;
 
  function   redirect(x){ 
  
  for   (m=temp.options.length-1;m>0;m--){
   temp.options[m]=null;
  }   
  for   (i=0;i<group[x].length;i++){   
   temp.options[i]=new   Option(group[x][i].text,group[x][i].value);   
  }   
  temp.options[0].selected=true;
    
  if(search.zone.value="文章"){
     search.action="blog_list.asp";
  }else search.action="index.asp";
  redirect1(0);   
  }  
  
  </script>

我这样写的代码但是好像不对吗,没有预期的效果  <script language="javascript">     var   groups=document.search.zone.options.length;   
  var   group=new   Array(groups);  
  for   (i=0;   i<groups;   i++)   
  group[i]=new   Array();   
    
  group[0][0]=new   Option("请选择范围","   ");   
    
  group[1][0]=new   Option("类别","类别");   
  group[1][1]=new   Option("主题","主题");   
  group[1][2]=new   Option("标题","标题");   
  group[1][3]=new   Option("内容","内容");   
    
  group[2][0]=new   Option("类别","类别");   
  group[2][1]=new   Option("主题","主题");   
  group[2][2]=new   Option("名称","名称"); 
  group[2][3]=new   Option("说明","说明"); 
  
  group[3][0]=new   Option("歌手","歌手");   
  group[3][1]=new   Option("专辑","专辑");   
  group[3][2]=new   Option("歌名","歌名"); 
  group[3][3]=new   Option("备注","备注"); 
    
  var   temp=document.search.type;
 
  function   redirect(x){ 
  
  for   (m=temp.options.length-1;m>0;m--){
   temp.options[m]=null;
  }   
  for   (i=0;i<group[x].length;i++){   
   temp.options[i]=new   Option(group[x][i].text,group[x][i].value);   
  }   
  temp.options[0].selected=true;
    
  if(search.zone.value="文章"){
     search.action="blog_list.asp";
  }else search.action="index.asp";
  redirect1(0);   
  }  
  
  </script>
