js自动查找select下拉的菜单并选择(示例代码)

复制代码 代码如下:
function find_select(name)
{
 var select = document.getElementsByName(name);
 var find_str = document.getElementById('to_find_str').value;
 if(select)
 {
  select = select[0];
  var child = select.childNodes;
  var can=false,text='',len=child.length,is_end=true;
  for(var i=0;i  {
   if(can)
   {
    text = child[i].text;
    if( text &&
     text.indexOf(find_str)!=-1)
    {
     //console.log(text);
     child[i].selected = true;
     var v = child[i].value;
     select.value = v;
     select.onchange(v);
     is_end = false;
     break;
    }
   }
   if(child[i].selected)
    can = true;
  }
  if(is_end)
   alert('已没有匹配内容');
 }
}

复制代码 代码如下:
