Question

我正在尝试显示数据库中的数据，并在每行的末尾添加一个复选框。我已经尝试过html标签和CF标签但是在过去的几个小时里我遇到了错误..任何帮助都会很棒，因为我对ColdFusion完全不熟悉。下面是代码：

<cfset a = "BGCOLOR =###IIF(myQuery.currentrow MOD 2, DE('E6E6E6'),DE('C0C0C0'))#" />

<cfscript>
    For (i=1;i LTE myQuery.recordCount; i=i+1)


     writeoutput ("<TR " & a & "><TD>" & i & "</TD>" &
      "<TD>" & myQuery.UserID[i] & "</TD>" &
      "<TD>" & myQuery.FName[i] & "</TD>" &
      "<TD>" & myQuery.SName[i] & "</TD>"&
      "<TD>" & myQuery.Phone[i] & "</TD>"&
      "<TD>" & myQuery.DateJoined[i] & " </TD>"&
      "<TD>" & myQuery.Address[i] & "</TD>"&
      "<TD>" & <cfinput type="Checkbox" name="post_home">  & " </TD></TR>");


    </cfscript>

最后一行（第55行）导致错误提前致谢

第37行第55行找到无效的CFML构造。

Answer 1

您的<cfinput>标记周围缺少引号。你需要在这里使用单引号来正确连接。

<cfscript>
for ( i=1; i <= myQuery.recordCount; i++ ) {

  writeoutput ("<tr " & a & "><td>" & i & "</td>" &
  "<td>" & myQuery.UserID[i] & "</td>" &
  "<td>" & myQuery.FName[i] & "</td>" &
  "<td>" & myQuery.SName[i] & "</td>" &
  "<td>" & myQuery.Phone[i] & "</td>" &
  "<td>" & myQuery.DateJoined[i] & "</td>" &
  "<td>" & myQuery.Address[i] & "</td>" &
  "<td>" & '<input type="checkbox" name="post_home">' & "</td></tr>");

}
</cfscript>

或者，您可以将最后一行全部放在单引号中。

'<td><input type="checkbox" name="post_home"></td></tr>');

Answer 2

你可以轻松地完成它，而不使用cfscript。

<cfoutput query = "myQuery">
<tr>
    <td>#myQuery.userid#</td>
    ... other display fields
    <td><input type="checkbox" name="post_home" value="#something#"></td>
</tr>
</cfoutput>

Answer 3

请注意，您的示例中没有定义a，并且复选框没有要传递的值，因为它未定义。另外，不要在i var。

周围放置哈希值

<cfscript>
        for ( i=1; i <= myQuery.recordCount; i++ ) {

             writeoutput ("<tr " & myQuery.currentRow MOD 2 ? '##E6E6E6' : '##C0C0C0' & "><td>" & i & "</td>" &
                "<td>" & myQuery.UserID[i] & "</td>" &
                "<td>" & myQuery.FName[i] & "</td>" &
                "<td>" & myQuery.SName[i] & "</td>" &
                "<td>" & myQuery.Phone[i] & "</td>" &
                "<td>" & myQuery.DateJoined[i] & "</td>" &
                "<td>" & myQuery.Address[i] & "</td>" &
                "<td><input type='checkbox' name='post_home'></td></tr>");

            }
</cfscript>
