我正在使用Materialisecss。现在我正在创建一个酒店预订系统。我想要的是,当我在DateIn Datepicker上选择日期时,DateOut Datepicker最小日期应该比所选日期提前1天。首先选择它是有效的。但是当我尝试选择高于所选日期的支票日期时,日期选择器的最小日期不会改变。
$('#dp_ci').pickadate(
{
selectMonths: true, // Creates a dropdown to control month
min : new Date(),
clear: 'Clear',
close: 'Ok',
closeOnSelect: false // Close upon selecting a date,
});
$('#dp_ci').change(function(){
selected_ci_date ="";
selected_ci_date = $('#dp_ci').val();
if (selected_ci_date != null)
{
var cidate = new Date(selected_ci_date);
alert(cidate);
$("#dp_co").val("");
$("#dp_co").removeAttr("disabled");
min_codate = "";
min_codate = new Date();
min_codate.setDate(cidate.getDate()+1);
$('#dp_co').pickadate(
{
min : min_codate,
selectMonths: true, // Creates a dropdown to control month
clear: 'Clear',
close: 'Ok',
closeOnSelect: false // Close upon selecting a date,
});
$('#dp_co').change(function(){
if ($('#dp_co').val() != null)
{
var ci = new Date($('#dp_ci').val());
var co = new Date($('#dp_co').val());
var noOfdays = co.getDate() - ci.getDate() ;
alert(noOfdays);
}
});
}
})
编辑: 例: 第一选择: dp_ci:2017年9月27日(已选中) dp_co(分钟):2017年9月28日(后面的日期被禁用) dp_co:2017年9月28日(已选中)
第二选:(我将再次选择dp_ci) dp_ci:2017年9月29日(已选中) dp_co(分钟):2017年9月28日(原定应该是9月29日)
更新:我找到了能够解决问题的答案。唯一的事情是dp_co的最小日期不应该与dp_ci允许相同的日期:任何解决方案?
$('#dp_ci').pickadate(
{
selectMonths: true, // Creates a dropdown to control month
today: 'Today',
clear: 'Clear',
close: 'Ok',
min: new Date()
});
var from_$input = $('#dp_ci').pickadate(),
from_picker = from_$input.pickadate('picker')
var to_$input = $('#dp_co').pickadate(),
to_picker = to_$input.pickadate('picker')
// Check if there’s a “from” or “to” date to start with.
if ( from_picker.get('value') )
{
to_picker.set('min', from_picker.get('select'))
}
if ( to_picker.get('value') )
{
from_picker.set('max', to_picker.get('select'))
}
// When something is selected, update the “from” and “to” limits.
from_picker.on('set', function(event)
{
if ( event.select )
{
to_picker.set('min', from_picker.get('select'))
}
else if ( 'clear' in event )
{
to_picker.set('min', false)
}
})
to_picker.on('set', function(event)
{
if ( event.select )
{
from_picker.set('max', to_picker.get('select'))
}
else if ( 'clear' in event )
{
from_picker.set('max', false)
}
})

您需要在启动选择器和结束选择器上保存picker
对象,并在startpicker
更改时 - 您只需要set
min
end
选择器的值:
var startdate = $('#dp_ci').pickadate('picker');
var enddate = $('#dp_co').pickadate('picker');
$('#dp_ci').change(function() {
if (selected_ci_date != null) {
enddate.set('min', min_codate);
}
})
以下是完整的示例:
$('#dp_ci').pickadate({
selectMonths: true, // Creates a dropdown to control month
min : new Date(),
clear: 'Clear',
close: 'Ok',
closeOnSelect: false // Close upon selecting a date,
})
var startdate = $('#dp_ci').pickadate('picker');
$('#dp_co').pickadate({
min : new Date(),
selectMonths: true, // Creates a dropdown to control month
clear: 'Clear',
close: 'Ok',
closeOnSelect: false // Close upon selecting a date,
})
var enddate = $('#dp_co').pickadate('picker');
$('#dp_ci').change(function() {
selected_ci_date ="";
selected_ci_date = $('#dp_ci').val();
if (selected_ci_date != null) {
var cidate = new Date(selected_ci_date);
alert(cidate);
$("#dp_co").val("");
$("#dp_co").removeAttr("disabled");
min_codate = "";
min_codate = new Date();
min_codate.setDate(cidate.getDate()+1);
enddate.set('min', min_codate);
}
})
