.Highlighted a{
background-color : Green !important;
background-image :none !important;
color: White !important;
font-weight:bold !important;
font-size: 9pt;
}
$(document).ready(function () {
var date1 = new Date(2014, 5, 6);
var date2 = new Date(2014, 5, 17);
$('#datepicker').datepicker({
dateFormat: "mm/dd/yy",
beforeShowDay: function (date) {
if (date == date1 ) {
return [true, 'Highlighted', 'Available Date'];
}
return [false, '', ''];
}
});
});
This one doesn't work, because of date==date1
. If I change it to date<=date1
, it works fine. I thought javascript is a weakly typed language and it compares the content, rather than reference. I don't wanna do something like (date.getDay==date1.getDay &&....)
. Is there an easier way to compare the values?
Use the +
unary operator ( reference ) to convert the values to numerics for comparison.
The unary + operator converts its operand to Number type.
if (+date === +date1 ) {
return [true, 'Highlighted', 'Available Date'];
}
OR
if (!(date - date1)) {
return [true, 'Highlighted', 'Available Date'];
}
正如本文所述,您希望使用以下内容来比较日期:
date.getTime() == date1.getTime()
其他方式:
if (date.valueOf() == date1.valueOf())
