根据先前的输入隐藏表单中的动态字段值

标签： jquery forms validation hide

在我写的代码中，我有两个主要目标。第一个是确定用户工作的小时数，另一个是建立加班工作。 现在您可以在下面的代码中看到，用户可以选择何时工作。

现在的问题是： 如何让我的加班字段动态隐藏不相关的小时数？

如果用户从07:00到17:00工作。我希望他能够在加时赛中的那些时间之间做出选择。我知道我需要使用jquery，但更多的具体指南将不胜感激 代码如下：

<tr >

另一个例子包括：

如果X先生从凌晨03:00到下午16:00完成工作，他想填写加班费。加班费字段只能显示从03:00到16:00的值。

原因是：如果它不属于他在工作的from和to字段中列出的值之间，他就无法指定他已经工作的加班。

代码

var items=  $('#ovt_f_hour')[0].options;
var overtimeHour = 15;
$.each(items,function(i,v){
        if(i<=overtimeHour){
        $(v).prop("disabled","disabled").css("background-color","#ccc")

$('#to_hour').on("change",function(){
var items=  $('#ovt_f_hour')[0].options;


var start_overtimeHour = $('#from_hour option:selected').text();
var end_overtime= $('#to_hour option:selected').text();
$.each(items,function(i,v){
        if(i>=start_overtimeHour&&i<=end_overtime){     
        }else{
        $(v).prop("disabled","disabled").css("background-color","#ccc");
        }
