最近一直在學習coldfusion，今天遇到了一個動態增行，並進行批量保存的問題，搞了半天終於搞定啦，發出來和大家分享一下。
以下是具體代碼，感興趣的朋友可以看看：
<cfprocessingdirective pageencoding="utf-8">
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script src="webroot/js/jquery.js"></script>
<script>
function addCustomField(id){
val = parseInt(Math.random()*100);
tr_id = $("#test>tbody>tr:last").attr("id");
tr_id++;
str = "<tr><td><input type='text' name='username_"+val+"'/><input type='password' name='userpass_"+val+"' /></td></tr>";
$('#'+id).append(str);
}
</script>
<cfif isDefined("form.submit")>
<cfif isdefined("form.fieldnames")>
<cfif form.fieldNames CONTAINS "username_">
<cfloop list="#form.fieldnames#" index="i">
<cfif i CONTAINS "username_">
<cfset fieldid = listRest(i,"_")>
<cfquery name="batch" datasource="#request.dsn#">
insert into cf_user(name,pass)
values(
'#evaluate("form.username_" & fieldid)#',
'#evaluate("form.userpass_" & fieldid)#'
)
</cfquery>
</cfif>
</cfloop>
</cfif>
</cfif>
</cfif>
<title>無標題文檔</title>
</head>
<body>
<cfform>
<table id="cust_table">
<tr>
<td>用戶註冊</td>
</tr>
<tr>
<td>
<input type="text" name="username_1" />
<input type="password" name="userpass_1" />
</td>
<td><img src="images/admin_add.jpg" onclick="addCustomField('cust_table');"/></td>
</tr>
<input type="submit" name="submit" value="註冊" />
</table>
</cfform>
</body>
</html>
數據庫當然還是最簡單的用戶表，只有三個字段：
create table cf_user(
id int primary key auto_increment,
name varchar(20),
pass varchar(20)
)以上就是全部的信息啦，感興趣的朋友可以一起交流coldfusion的信息，本人ＱＱ：395079181
