我正在使用jQuery" datetimepicker"我想将"设置为日期"价值取决于"从日期"值和包含以下值的“选择”框值。
1-周(7天以上)
2-每月(30天以上)
半年半(6个月以上)
3年(1年以上)
示例:
1-选择日期:2015-05-29
2-持续时间每月
3-迄今为止应该是2015-06-29
我使用以下代码选择日期开始日期。
jQuery('#start_date').datetimepicker({
format:'m/d/Y',
closeOnDateSelect:true,
timepicker:false
});
请建议。

如果我理解正确,你会有这样的事情:
a)像这样的选择框
Options :
<select id="time">
<option value="1">Weekly (7+ days)</option>
<option value="2">Monthly (30+ days)</option>
<option value="3">Half Yearly (6+ months)</option>
<option value="4">Yearly (1+ Year)</option>
</select>
b)和两个日期选择器,如下:
Select From Date :
<input id="start_date" type="text" />
Select END Date :
<input id="end_date" type="text" />
c)日期选择器和onSelect函数的代码将更改第二个日期选择器:
/** addExtraTime() function
* this function changes the second datepicker ( $('#end_date').datepicker )
* according to the selected value of select box.
*/
var addExtraTime = function (aDateObj) {
var actualDate = aDateObj;
var newDate = aDateObj;
var extraTime = $('#time').val(); //string
if (extraTime === '1') { //Weekly = +7d
newDate = new Date(actualDate.getFullYear(), actualDate.getMonth(), actualDate.getDate() + 7);
$('#end_date').datepicker('setDate', newDate);
} else if (extraTime === '2') { //Monthly = +1m
newDate = new Date(actualDate.getFullYear(), actualDate.getMonth() + 1, actualDate.getDate());
$('#end_date').datepicker('setDate', newDate);
} else if (extraTime === '3') { //Half Yearly = +6m
newDate = new Date(actualDate.getFullYear(), actualDate.getMonth() + 6, actualDate.getDate());
$('#end_date').datepicker('setDate', newDate);
} else if (extraTime === '4') { //Yearly = +1y
newDate = new Date(actualDate.getFullYear() + 1, actualDate.getMonth(), actualDate.getDate());
$('#end_date').datepicker('setDate', newDate);
} //End of if..else
};
/* We watch for changes in the select box and call the addExtraTime() */
$('#time').change(function () {
var currentDate = $('#start_date').datepicker("getDate");
addExtraTime(currentDate);
});
/* From Date picker */
$('#start_date').datepicker({
format: 'm/d/Y',
closeOnDateSelect: true,
timepicker: false,
onSelect: function (selectedDate) {
/*
* selectedDate is a string so we convert is to a Date obj
*/
var selectedDateObj = new Date(selectedDate);
addExtraTime(selectedDateObj);
} //End of onSelect
});
/* To Date picker */
$('#end_date').datepicker({
format: 'm/d/Y',
closeOnDateSelect: true,
timepicker: false
});
您可以看到此操作:here
