我使用datetimepicker在表单中设置值。我一直试图限制用户选择开始时间之前的结束时间。我已经尝试设置mindate,hourmin,一个等于开始日期的新日期,但没有成功。根据我的看法,以下代码应该可以工作,但事实并非如此。
<script src="../js/jquery-1.9.1.js"></script>
<script src="../js/jquery-ui-1.10.3.custom.js"></script>
<script src="../js/jquery-ui-timepicker-addon.js"></script>
<script src="../js/jquery-ui-sliderAccess.js"></script>
<script>
$(function()
{
var startDateTextBox = $('#startDate');
var endDateTextBox = $('#endDate');
var startTimeTextBox = $('#startTime');
var endTimeTextBox = $('#endTime');
startDateTextBox.datepicker(
{
minDate: ("setDate", '',new Date()),
hourGrid: 12,
minuteGrid: 15,
stepMinute: 15,
onClose: function(dateText, inst) {
if (endDateTextBox.val() != '')
{
var testStartDate = startDateTextBox.datetimepicker('getDate');
var testEndDate = endDateTextBox.datetimepicker('getDate');
if (testStartDate > testEndDate)
endDateTextBox.datetimepicker('setDate', testStartDate);
}
else
{
endDateTextBox.val(dateText);
}
},
onSelect: function (selectedDateTime){
endDateTextBox.datetimepicker('option', 'minDate', startDateTextBox.datetimepicker('getDate') );
}
}
);
startTimeTextBox.datetimepicker(
{
timeOnly:true,
minuteGrid: 15,
stepMinute: 15,
minDate: ("setTime", '',new Date()),
timeFormat: 'hh:mm tt',
onClose: function(dateText, inst)
{
if (endTimeTextBox.val() != '')
{
var testStartTime = startTimeTextBox.datetimepicker('getDate');
var testEndTime = endTimeTextBox.datetimepicker('getDate');
if(testStartTime > testEndTime)
endTimeTextBox.timepicker('setTime', testStartTime);
}
else
{
endTimeTextBox.val(dateText)
}
},
onSelect: function (selectedDateTime){
endTimeTextBox.datetimepicker('setDate', startTimeTextBox.datetimepicker('getDate') );
}
}
);
endDateTextBox.datepicker(
{
hourGrid: 12,
minuteGrid: 15,
stepMinute: 15,
onClose: function(dateText, inst)
{
if (startDateTextBox.val() != '')
{
var testStartDate = startDateTextBox.datetimepicker('getDate');
var testEndDate = endDateTextBox.datetimepicker('getDate');
if (testStartDate > testEndDate)
startDateTextBox.datetimepicker('setDate', testEndDate);
}
else
{
startDateTextBox.val(dateText);
}
},
onSelect: function (selectedDateTime){
startDateTextBox.datetimepicker('option', 'maxDate', endDateTextBox.datetimepicker('getDate') );
}
}
);
endTimeTextBox.datetimepicker(
{
timeOnly:true,
minuteGrid: 15,
stepMinute: 15,
timeFormat: 'hh:mm tt',
onClose: function(dateText, inst)
{
if (startTimeTextBox.val() != '')
{
var testStartTime = startTimeTextBox.datetimepicker('getDate');
var testEndTime = endTimeTextBox.datetimepicker('getDate');
if (testStartTime > testEndTime)
endTimeTextBox.datetimepicker('setDate', testStartTime);
}
else
{
startTimeTextBox.val(dateText);
}
},
onSelect: function (selectedDateTime){
startTimeTextBox.datetimepicker('option', 'maxDate', endTimeTextBox.datetimepicker('getDate') );
}
}
);
}
);
</script>
代码的逻辑似乎是正确的,为什么它不起作用? 到目前为止我想出的是:
$(function()
{
var startDateTextBox = $('#startDate');
var endDateTextBox = $('#endDate');
startDateTextBox.datetimepicker(
{
altField:"#startTimeALT",
altFieldTimeOnly: true,
timeFormat: "h:mm tt",
minDate: ("setDate", '',new Date()),
hourGrid: 12,
minuteGrid: 15,
stepMinute: 15,
onClose: function(dateText, inst)
{
if (endDateTextBox.val() != '')
{
var testStartDate = startDateTextBox.datetimepicker('getDate');
var testEndDate = endDateTextBox.datetimepicker('getDate');
if (testStartDate > testEndDate)
endDateTextBox.datetimepicker('setDate', testStartDate);
}
else
{
endDateTextBox.val(dateText);
}
},
onSelect: function (selectedDateTime){
endDateTextBox.datetimepicker('option', 'minDate', startDateTextBox.datetimepicker('getDate') );
}
}
);
endDateTextBox.datetimepicker(
{
minDate: ("setDate", '',new Date()),
altField:"#endTimeALT",
altFieldTimeOnly: true,
timeFormat: "h:mm tt",
hourGrid: 12,
minuteGrid: 15,
stepMinute: 15,
onClose: function(dateText, inst)
{
if (startDateTextBox.val() != '')
{
var testStartDate = startDateTextBox.datetimepicker('getDate');
var testEndDate = endDateTextBox.datetimepicker('getDate');
if (testStartDate > testEndDate)
startDateTextBox.datetimepicker('setDate', testEndDate);
}
else
{
startDateTextBox.val(dateText);
}
},
onSelect: function (selectedDateTime){
startDateTextBox.datetimepicker('option', 'maxDate', endDateTextBox.datetimepicker('getDate') );
}
}
);
}
);
在上面的代码中,我使用datetimepicker jquery插件分隔了日期和时间字段。我这样做是为了更好地控制输入以及如何将其存储在数据库中。我希望这将有助于我的查询,并允许更容易的搜索和更新功能。这是用PHP编写的调度项目的一部分,jquery支持用户交互。非常感谢您在此努力中提供的任何帮助和建议!
答案 0 :(得分:2)
这个想法是正确的,问题是如何比较你的日期。我试过调用datepicker("getDate")
,它返回一个String,我假设你的datetimepicker插件是相同的。
您比较的字符串看起来像Wed Jun 12 2013 00:00:00 GMT+0200 (CEST)
,这里的等式只是基于Weekdate的字典顺序。
但是如果你使用JavaScript方法Date.parse(),你可以轻松地比较它们:
var testStartDate = startDateTextBox.datetimepicker('getDate');
var testEndDate = endDateTextBox.datetimepicker('getDate');
if (Date.parse(testStartDate) > Date.parse(testEndDate))
endDateTextBox.datetimepicker('setDate', testStartDate);
有了这个要点,我有一个玩具网站,你可以尝试验证,第一个日期已经有效:https://gist.github.com/contradictioned/5871967
