集成 Flex 4.6 和 Coldfusion
Integrating Flex 4.6 and Coldfusion
我在让我的 Flex 前端表单将其数据传递到 Coldfusion 以及随后的 SQL 服务器方面遇到了一些挑战。下面是我的代码：

我的表单有一个日期选择器。如何将选定的日期传回 CFC？当我尝试时，出现 Coldfusion 错误，提示 flex 值不是日期类型，因此我将 varchar 作为值类型，但仍然出现错误。我试图解决这个问题，以便我在 Flex 和 CF 之间的远程对象调用验证它是否有效。我已经包含了我的初步代码。如有任何想法，我们将不胜感激。
如果您将日期作为字符串从 flex 发送到 Coldfusion，则将 dob 定义为 Coldfusion 中的字符串：
<cfargument name="dob" type="string">
当你调用远程函数时，我看到你正在传递DOB.name。将 DOB.selectedDate 转换为字符串。您可以使用 getDOBString(DOB.selectedDate)
您可以定义函数如下：
private function getDOBString(date:Date):String{
var df:DateFormatter = new DateFormatter();
df.formatString = "MM/DD/YYYY";
var dateString:String = df.format(date);
return dateString;
}
我在让我的 Flex 前端表单将其数据传递到 Coldfusion 以及随后的 SQL 服务器方面遇到了一些挑战。下面是我的代码：

我的表单有一个日期选择器。如何将选定的日期传回 CFC？当我尝试时，出现 Coldfusion 错误，提示 flex 值不是日期类型，因此我将 varchar 作为值类型，但仍然出现错误。我试图解决这个问题，以便我在 Flex 和 CF 之间的远程对象调用验证它是否有效。我已经包含了我的初步代码。如有任何想法，我们将不胜感激。
如果您将日期作为字符串从 flex 发送到 Coldfusion，则将 dob 定义为 Coldfusion 中的字符串：
<cfargument name="dob" type="string">
当你调用远程函数时，我看到你正在传递DOB.name。将 DOB.selectedDate 转换为字符串。您可以使用 getDOBString(DOB.selectedDate)
您可以定义函数如下：
private function getDOBString(date:Date):String{
var df:DateFormatter = new DateFormatter();
df.formatString = "MM/DD/YYYY";
var dateString:String = df.format(date);
return dateString;
}
