我想在网站上添加其他功能，包括只能提交一次表单的功能，这样当用户刷新时，所有内容都不会再次处理等。
我已经使用Jquery和javascript查看了几段代码但是想知道在Coldfusion中是否有任何方法可以做到这一点，以及其他使用Coldfusion的人如何做到这一点？如果可能的话，我正在寻找最简单而有效的解决方案。
以下是我要禁用的表单示例＆＃34;重新提交＆＃34; funtionality：
<cfinclude template="header.cfm">
<cfparam name="form.step" default="1">
<cfparam name="form.submit" default="">
<cfparam name="form.finish" default="">
<script type='text/javascript'>
//<![CDATA[
$(document).ready(function() {
var currentItem = 1;
$('#addnew').click(function(){
currentItem++;
$('#items').val(currentItem);
var strToAdd = '<tr><td class="Copy" valign="top">Item Name:</td><td><input type="text" name="Itemname'+currentItem+'" id="Itemname'+currentItem+'" required="yes" message="Please enter a Name" class="TextBlock"></td></tr><tr><td class="Copy" valign="top">Item Description:</td><td><input type="text" name="ItemDesc'+currentItem+'" id="ItemDesc'+currentItem+'" required="yes" message="Please enter a Description" class="TextBlock"></td></tr><tr><td class="Copy" valign="top">Quantity</td><td><input type="text" name="Quantity'+currentItem+'" id="Quantity'+currentItem+'" required="yes" message="Please enter a Quantity" class="TextBlock"></td></tr><tr><td class="Copy" valign="top">Product Code:</td><td><input type="text" name="Code'+currentItem+'" id="Code'+currentItem+'" required="yes" message="Please enter a Code" class="TextBlock"></td></tr><tr><td class="Copy" valign="top">Price:</td><td><input type="text" name="Price'+currentItem+'" id="Price'+currentItem+'" required="yes" message="Please enter a Price" class="TextBlock"></td></tr>';
$('#data').append(strToAdd);
});
});

我没有使用像cfqueryparam这样的东西，因为它仍在开发中并且在安全的环境中
提前谢谢

我曾经做过这样的事情（很长一段时间使用它，代码可能会关闭，但更多的是一个想法）：
<cfparam name="form.submitted" default=0>
<cfif structKeyExists(FORM,"submit") AND NOT FORM.submitted>
<!---action code goes here--->
<cfset form.submitted=1>
</cfif>
<form>
<!--- your other form elements--->
<input type="hidden" name="submitted" value="#FORM.submitted#">
</form>
我不确定，它可以通过多步骤形式帮助您，但通过在提交表单时设置标志，它有助于单步避免多次提交。

您可以重定向到同一页面，这样可以避免重新发布表单。
答案 2 :(得分：0)
几天前我遇到过类似的情况。据我所知，最好的解决方案是，
重定向到其他某个页面，以防止重新提交表单。
如果重定向不合适，唯一的另一个选择是使用AJAX。
