Question

我最近在ColdFusion 11中开始开发，并且我遇到了cfselect的“bind”属性的一些问题。我一直在网上研究和阅读可用的文档，但我仍然有同样的错误。

我正在尝试使用两个选择框构建数据输入表单，其中选择框2中的值取决于选择框1中的选择。

提前感谢您的帮助。这是代码：

dsp_DataEntry.cfm：

    <html> 
<head> 
<title>Insert Data Form</title> 
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
</head> 

<body> 
<h2>Insert Data Form</h2> 

<cfset dataObj = CreateObject("component", "qry_DDContents")>

<table> 

<cfform id = "entry" name="entry" action="" method="post"> 

<tr>
    <td>Plant: </td>
    <td>
        <cfinput type="text" name="plantID" size="10" required="true" value=#session.FacilityID# >

    </td>

</tr>
<tr> 
    <td>Process:</td> 
    <td><cfselect name="ItemId" bind="cfc:qry_DDContents.getData()" bindonload="true" multiple="false" /></td> 
</tr>

<tr> 
    <td>Subprocess:</td> 
    <td><cfselect name="DepItemId" bind="cfc:qry_DDContents.getSub({ItemId})" multiple="false"/></td> 
</tr> 

<tr> 
    <td>Equipment Name:</td> 
    <td><input type="Text" name="equipmentname" size="4" maxlength="20" required="true"></td> 
</tr> 
<tr> 
    <td>Date out of Service:</td> 
    <td><input type="date" name="dateOutOfService" required="true"></td> 
</tr> 

<tr> 
    <td>Ecpected Return To Service:</td> 
    <td><input type="date" name="dateExpectedReturnToService" required="true"></td> 
</tr>

<tr> 
    <td>Date Returned To Service:</td> 
    <td><input type="date" name="dateReturnedToService" required="true"></td> 
</tr>

<tr> 
<td>Reason:</td> 
<td><input type="Text" name="reason" size="150" maxlength="255" 

required="true"></td> 
</tr> 

<tr> 
    <td>&nbsp;</td> 
    <td><input type="Submit" value="Submit">&nbsp;<input type="Reset" 
value="Clear Form"></td> 
</tr> 
</cfform> 
<!--- end html form ---> 
</table> 

</body> 
</html>

<cfreturn result>

</cffunction>

<cfloop index="i" from="1" to="#data.recordCount#">

Answer 1

我能够在本地复制此内容。我将CFFORM移到了表格标签之外，它可以工作。这是在FireFox和Chrome中。
