Question

发布表单时出现此错误。但最奇怪的是，此错误仅发生在Chrome和Safari中。 FF，IE和Opera都没有问题发布表格。

堆栈跟踪不指向发生此错误的文件。 cfcatch的cfdump给了我一些关于问题是什么的见解，但我找不到问题实际存在的任何实例。这是部分转储：

Column     1
Detail     The variable attributes. ends with a "." character. You must supply an additional structure key or delete the "." character.
KnownColumn  -1
KnownLine   -1
KnownText   "unknown"
Line         1
Message   A CFML variable name cannot end with a "." character.

这是处理发布数据的代码。一切都包含在cftransaction中，并且有一个循环，不知道为什么它没有被显示。（感谢Peter Boughton清理它）

这是表单和Javascript。我没有机会重写前一个开发人员的代码（直到这一点，它正在工作，所以首先没有必要访问代码），但CFFORM没有使用，也没有其他CF表格项目。各种JS函数用于AJAX调用，也包括在内。

Answer 1

问题已解决：选择列表没有定义name属性，因此，属性变量确实有一个空字段名称，从而导致错误。在我的例子中，选择列表不在CF中使用，而只在JS中使用。即使字段缺少名称，Chrome和Safari也会传递字段的值，而IE，FF和Opera则不会。感谢您指导我朝着正确的方向前进。

Answer 2

从您的描述中可以看出，错误是由客户端中的表单本身引发的，而不是您在上面发布的处理代码。如果您在调用页面上有cfform / cfgrid，您可能需要查看由CF生成的Javascript并针对Chrome / Safari进行测试。

CFML变量名称不能以“。”结尾。字符错误
