在coldfusion中使用javascript进行表单验证

我正在尝试验证两个字段。一个是开放时间,另一个是关闭时间。我的验证应该检查关闭时间是否具有除“00”以外的值,我的开放时间也应该具有大于“00”的值。

我的问题是,我做错了什么?我知道我的功能必须有错误。

这是我到目前为止所写的验证:

<script type="text/javascript">

function hoursFunction(formObject, formField, fieldValue)
{  
  var closeHours = document.getElementById('closeHours#CountVar#');
  var openHours = document.getElementById('openHours#CountVar#');

  if(closeHours != "00" && openHours == "00")
  {
    sfm_show_error_msg('Enter a valid opening time');
  }
}

这是我的表格样本

<form id="hoursForm" action="physician_businessHours.cfm?docID=<cfoutput>#docid#</cfoutput>" method="post" onsubmit="hoursFunction();">
            <input type="hidden" name="postitnow" value="yes">


                    <table border="1">

                    <tr>
                        <th>Day</th><th>Open Time</th><th>Close Time</th>
                    </tr>


                    <cfloop from="1" to="7" index="CountVar">

                    <cfset dayFound= 0>
                    <tr>
                        <td><cfif CountVar eq 1>Mon<cfelseif CountVar eq 2>Tues<cfelseif CountVar eq 3>Wednes<cfelseif CountVar eq 4>Thurs<cfelseif CountVar eq 5>Fri<cfelseif CountVar eq 6>Satur<cfelseif CountVar eq 7>Sun</cfif>day</td>

                        <cfoutput>

                        <td>   
                        <select id="openHours#CountVar#" name="openHours#CountVar#">
                         <cfloop query="doctorHours">
                        <cfloop from="00" to="23" index="OpenHours">  
                        <option  value="#openHours#"<cfif TimeFormat(doctorHours.openTime,'HH') EQ OpenHours AND CountVar EQ doctorHours.day > selected="selected"</cfif>>#OpenHours#</option>
                        </cfloop>
                        </cfloop>
                        </select>
                         </td>

     <td>     
                        <select id="closeHours#CountVar#" name="closeHours#CountVar#">
                        <cfloop query="doctorHours">
                        <cfloop from="00" to="23" index="closeHours">  
                        <option value="#closeHours#"
                        <cfif TimeFormat(doctorHours.closeTime,'HH') EQ closeHours AND CountVar EQ doctorHours.day  > selected="selected"</cfif>>#closeHours#</option>
                        </cfloop>
                        </cfloop>
                        </select>
                        </td>
                         </tr>

      <input type="hidden" name="Validate" onValidate="hoursFunction" message="You must select an opening hour">

     <input type="submit" value="Update" id="Submit">
                    '

您需要从元素中获取值:

  var closeHours = document.getElementById('closeHours#CountVar#').value;
  var openHours = document.getElementById('openHours#CountVar#').value;

答案 1 :(得分:1)

我明白了。您需要获取正确的元素ID:

for (var i = 0; i < 7; i++) {
    var closeHours = document.getElementById('closeHours' + i).value;
    var openHours = document.getElementById('openHours' + i).value;

    if (closeHours != "00" && openHours == "00") {
      sfm_show_error_msg('Enter a valid opening time');
    }
}

你的CountVar从1开始,而不是0,所以你的for循环应该是相同的。 另外,为防止表单提交,如果表单未验证,则hoursFunction()应返回false。 另外,你的hoursFunction()需要3个参数,但你没有传递任何参数 - 在这种情况下这些参数不是必需的,所以只需从函数定义中删除它们。 尝试以下功能:

function hoursFunction() {
  for (var i = 1; i <= 7; i++) {
    var closeHours = document.getElementById('closeHours' + i).value;
    var openHours = document.getElementById('openHours' + i).value;
    if (closeHours != "00" && openHours == "00") {
      sfm_show_error_msg('Enter a valid opening time');
      return false;
    }
    return true;
  }
}

答案 3 :(得分:0)

这是我编写的代码,到目前为止工作正常:

function hoursFunction()
{  

    var i = 0;
    var openHour;
    var closeHour;

    for(i=1;i<8;i++)
    {
     openHour = document.getElementById("openHours" + i).value;
     closeHour= document.getElementById("closeHours" + i).value;

    if(openHour > closeHour)
    {   
        document.getElementById('error').innerHTML= "Error at " + i;  
        return false; 
    }
    document.getElementById('error').innerHTML= "No Error occured";  
    return true;
    }
}

我现在的问题是,当我提交表单时,表单似乎正在刷新并删除我的所有数据...... 有什么想法?
