我再次在此处发布此问题，因为我需要以前的问题Checkbox in a ColdFusion form 的进一步帮助

<form action="view_emp_qual.cfm?show=yes" id="Myform" method="post" name="myform">

    <table id="tab1" align="center">
        <tr>
            <td>
            <input type="checkbox" onclick="return callme();" 
            <cfif structKeyExists(form, 'chkbox3')>
                checked="checked"
            </cfif>
            name="chkbox3" id="chkbox3"> 
            <strong>All Employees</strong>

            <input type="checkbox" onclick="return callme1();" 
            <cfif NOT structKeyExists(form, 'fieldnames') OR structKeyExists(form, 'chkbox1') OR (structKeyExists(form, 'fieldnames') and structKeyExists(form, 'chkbox1'))>
                checked="checked"
            </cfif>
            name="chkbox1" id="chkbox1" /> 
            <strong>Agreement Only</strong>

            <input type="checkbox" onclick="return callme1();" 
            <cfif NOT structKeyExists(form, 'fieldnames') OR structKeyExists(form, 'chkbox2') OR (structKeyExists(form, 'fieldnames') and structKeyExists(form, 'chkbox2'))>
                checked="checked"
            </cfif>
            name="chkbox2" id="chkbox2"/> 
            <strong>Active Employees</strong>

            <td>
            <input type="Submit" name="submitnow" value="View Selected" class="button1">
            <td>
            <input type="button" name="Back" value="Back to Previous Menu" onclick="javascript:document.location.href('qualyrs_maint.cfm');" class="button1">
        </tr>
    </table>
</form>

我现在有 3 个复选框，其中最后两个需要在页面加载时检查并显示查询结果。当最后两个未选中时，必须检查第一个并相应地显示查询结果。

现在我在页面上有一个排序列功能。像这样

<cfif isdefined("form.order_by") and form.order_by eq "EMPLID">
    background-color:##
    <cfif sort_order eq "asc">
        666666
    <cfelse>
        000000
    </cfif>
</cfif>
;"
onClick="sortBy('EMPLID');Sorting.style.display='block';">
EMPLID
<cfif isdefined("form.sort_order") and isdefined("form.order_by") and ucase(form.sort_order) eq 'ASC' and ucase(form.order_by) eq 'EMPLID'>
    <img src="images/desc.jpg">
<cfelseif isdefined("form.sort_order") and isdefined("form.order_by") and ucase(form.sort_order) eq 'DESC' and ucase(form.order_by) eq 'EMPLID'>
    <img src="images/asc.jpg">
</cfif>

这就是 JS

<script language="Javascript">
    function sortBy(order) {
            foo = document.getElementById("order_by_id");
            bar = document.getElementById("sort_order_id"); 
            <!---if (foo.value == order) {
                //same thing again, so flip the sort
                if (bar.value == 'DESC'){
                    bar.value = 'ASC';
                    }
                else{
                    bar.value = 'DESC';}
                //bar.value = bar.value == "ASC" ? "DESC" : "ASC";  
            } else {
                //new sort order, so make it ASC
                bar.value = "ASC";
            }--->
            foo.value = order;
            sort.submit();
        }
</script>

<cfscript>
    if(IsDefined('form.sort_order'))
    {
        if(form.sort_order IS 'ASC')
            sort_order_value = 'DESC';
        else
            sort_order_value = 'ASC';
    }
    else
        sort_order_value = 'ASC';
</cfscript>

<form action="view_emp_qual.cfm?show=yes" method="post" name="sort">
    <cfoutput>
        <cfparam name="order_by" default="">
        <input type="hidden" name="order_by" id="order_by_id" value="#order_by#">
        <input type="hidden" name="sort_order" id="sort_order_id" value="#sort_order_value#">

        <cfif Isdefined("Form.fieldnames")>
            <cfloop index="fieldname" list=#form.fieldnames#>
                <cfset fieldvalue = Evaluate("form." & #fieldname#)>
                <cfif not ("order_by,sort_order") contains fieldname>
                    <input type="hidden" name=##fieldname## value="#fieldvalue#">
                </cfif>
            </cfloop>
        </cfif>
    </cfoutput>
</form>

现在，我可以根据需要进行所有工作，除了在页面加载时选中最后两个复选框，然后点击排序列图标，然后选中第一个复选框。请告知我的代码哪里出错了。谢谢

您的问题/方法非常混乱，我花了很多时间试图了解您在做什么。我注意到错误但无法修复您的代码，因为很难阅读您所做的一些事情，我在下面创建了类似的东西 - 匆忙。它使用相同的形式进行排序和展示，并允许您使用其他几个“订单”键（empid ...）。我也对它发表了评论，这样你就可以理解我在每一点都在做什么。单击订单链接重新提交表单，传递当前表单中的相同值，在处理表单提交时，您可以使用 sort_order_value 和 order_by_value 进行任何您想要的操作。

<!--- initialized needed variables --->
<cfscript>
    isPost = structKeyExists(form, 'fieldnames'); //if form was submitted
    chkbox1Selected = structKeyExists(form, 'chkbox1'); //if chkbox1 is selected
    chkbox2Selected = structKeyExists(form, 'chkbox2'); //if chkbox2 is selected
    chkbox3Selected = structKeyExists(form, 'chkbox3'); //if chkbox3 is selected
    param name="order_by_value" default="EMPLID"; //default order_by_value is EMPLID
    if(structKeyExists(form, 'sort_order') AND form.sort_order IS 'ASC') //if  sort order was specified and it was ASC, change to DESC
        sort_order_value = 'DESC';
    else //if order wasnt selected, default is ASC and if DESC was sent, change to ASC
        sort_order_value = 'ASC';
</cfscript>
<cfoutput>
    <!--- for debugging --->
    isPost: #isPost#<br>
    chkbox1Selected: #chkbox1Selected#<br>
    chkbox2Selected: #chkbox2Selected#<br>
    chkbox3Selected: #chkbox3Selected#<br>
    sort_order_value: #sort_order_value#<br>
    <cfif structKeyExists(form, 'sort_order')>
        form.sort_order: #form.sort_order#<br>
    </cfif>
    <!--- end of debugging --->
