一个文本框:
一个下拉菜单
print "请输入文件名:".textfield(-name=>file);
print "请选择要删除的共享文件:".popup_menu(-name=>file1,-values=>[]);
在这个菜单中要怎样设values才能让在文本框中所埴写的文件名能立即反映在菜单里?
apparently, you need to write some client-side script to insert the content into the select or do a form submission in onchange event of 文本框. Here is an example:
<script language="javascript">
function addEntry()
{
var ele = event.srcElement;
var opt = new Option(ele.value,ele.value);
ele.form.select1.options.add(opt);
opt.selected = true;
}
</script>
<form name="form1">
<input type="text" name="txt1" onchange="addEntry()"><BR>
<select name="select1">
<option value="1">1</option>
</select>
</form>
