我只是将元素附加到面板包装器并调用.button()？
解决方法
如果要在滚动月份期间保持“清除”按钮，请使用onChangeMonthYear：。
一个例子：
$( "#datepicker" ).datepicker({
showButtonPanel: true,beforeShow: function( input ) {
setTimeout(function() {
var buttonPane = $( input )
.datepicker( "widget" )
.find( ".ui-datepicker-buttonpane" );
$( "<button>",{
text: "Clear",click: function() {
//Code to clear your date field (text Box,read only field etc.) I had to remove the line below and add custom code here
$.datepicker._clearDate( input );
}
}).appendTo( buttonPane ).addClass("ui-datepicker-clear ui-state-default ui-priority-primary ui-corner-all");
},1 );
},onChangeMonthYear: function( year,month,instance ) {
setTimeout(function() {
var buttonPane = $( instance )
.datepicker( "widget" )
.find( ".ui-datepicker-buttonpane" );
$( "<button>",read only field etc.) I had to remove the line below and add custom code here
$.datepicker._clearDate( instance.input );
}
}).appendTo( buttonPane ).addClass("ui-datepicker-clear ui-state-default ui-priority-primary ui-corner-all");
},1 );
}
});
