| 有一页填表的页面，其中有几个下拉表单是通过一个表的某个字段动态生成，比如省下面的城市名，希望选择某一个 省即可自动在另一下拉表单内生成城市名，.....然后提交给asp处理加入到另外一个表内。 终于完成了，代码如下，可能比较乱，不过还是很有效的，不用刷新页面。 大家不妨一试~~~~~~~~ <form name=f1 METHOD="POST"> <% OpenDB objConn, "xxxx" Set RSClass = objConn.Execute("SELECT * FROM class Order by fldClass") If RSClass.EOF Then Response.Write "没有记录。<BR>" Else Response.Write "<SELECT NAME=""class"" style=""FONT-SIZE: 9pt"" SIZE=10" & _ " ONCHANGE=""classselected(this);"" >" sjavaScript = "function classselected(elem){" &_ vbCrlf & _ "for (var i = document.f1.sort.options.length; i >= 0; i--){" & vbCrlf & _ "document.f1.sort.options[i] = null;" & _ vbCrlf Do Until RSClass.EOF If sLastClass <> RSClass("fldClass") Then sLastClass = RSClass("fldClass") Response.Write "<OPTION VALUE=" & RSClass("fldID") & ">" & sLastClass & "</OPTION>" sJavascript = sJavaScript & "}" & vbCrlf & _ "if (elem.options[elem.selectedIndex].value==" & _ RSClass("fldID") & "){" & vbCrlf End If sJavaScript = sJavaScript & _ "document.f1.sort.options[document." & _ "f1.sort.options.length] = new Option('" & _ RSClass("fldSort") & "','" & RSClass("fldID") & "');" & _ vbCrlf RSClass.MoveNext Loop Response.Write "</SELECT>" Response.Write "<SELECT NAME=""sort"" style=""FONT-SIZE: 9pt"" SIZE=10>" Response.Write "<OPTION>[请选择]</OPTION>" Response.Write "</SELECT>" sJavaScript = sJavaScript & vbCrlf & "}" & vbCrlf & "}" & vbCrlf Response.Write "<SCR" & "IPT LANGUAGE=""JavaScript"">" & vbCrlf Response.Write sJavaScript & vbCrlf & "</SCR" & "IPT>" & vbCrlf End If RSClass.Close Set RSClass = Nothing%> </form> 注意：联系我时，请一定说明是从【S】看到的信息，谢谢。 |
