不从复选框拾取表单值 [英] not picking up form values from checkbox

问题描述

我在Cold Fusion中有一个表单，其中包含一组复选框。我正在将此表单提交到页面frag5.cfm。 frag5.cfm中只有一行代码。

I have a form in Cold Fusion which contains a set of checkboxes. I am submitting this form to the page frag5.cfm. There is only one line of code in frag5.cfm.

<cfoutput>values are  #form.f1# </cfoutput>

此行显示values are - 即复选框的表单值，名称f1未被拾取。

This line shows "values are " -- that is, the form values for the checkboxes, all with name f1 are not being picked up.

这是错误的方法来获取这些值吗？有人能告诉我正确的事吗？原始格式如下：

Is this the wrong way to pick up these values? Could someone tell me the right thing to do? The original form is below:

<form name      = "fields"
  action    = "frag5.cfm"
  method    = "post"       
  onkeypress = "return event.keyCode != 13;">  
<table style = "margin-left:165px" >
<caption style = "padding-top: 20px" >Restrict Report To: </caption>
<tr>
<td>Master Event:</td>
 <td><input type = "checkbox" 
            id   = "cb_e"
            name = "f1" 
            value = "" 
            onclick = ischecked("cb_e","hid_e")
            class = "check1">
 <label for = "cb_e">&nbsp; </label>
 <input type = "hidden" name = "finsel" id = "hid_e" value = "unchecked">
</td> 
<td style = "width: 25px"> &nbsp; </td>
<td>SubEvent:</td>
  <td><input type = "checkbox" 
             id = "cb_s" 
             value = "" 
             name = "f1"
            onclick = ischecked("cb_s","hid_s")                
            class = "check1" >
  <label for = "cb_s">&nbsp; </label></td>
   <input type = "hidden" name = "finsel" id = "hid_s" value = "unchecked">
  </td>     
  </tr>
</table>
<table style ="margin-left: 175px; margin-top: 20px;" >
<td style = "width: 150px;" id = "chuprep" class = ixes2">&nbsp;       
</td>
<td style = "width: 150px;"> 
 <input type = "Submit"
        name  ="Submitfin1" 
        class = "submitbut"            
        value = "Submit" > 
</td>
</tr>
</table> 
</form>

ischecked is：

The code for ischecked is :

function ischecked(id, passid) {
//alert("got to ischecked" + id + passid);

var ischeck = document.getElementById(id).checked; 

if(ischeck){
document.getElementById(passid).value = "checked";}
else {
document.getElementById(passid).value = "unchecked";}

}//end function ischeck

推荐答案

如果你试图检查未选中的复选框的值，我不认为他们会可以使用 structKeyExists（FORM，'f1'）来检查值是否存在。

If you are trying to check the values of unchecked checkboxes I don't think they will show up in the FORM scope. If the checkboxes are checked, then they should show up. You can use structKeyExists(FORM, 'f1') to check if a value exists.
