这里有两个日期fromDate
和toDate
,我想检查fromDate
<toDate
,但它只检查日期是否较小。例如,如果您放置fromDate: 01/01/2016
和toDate: 15/01/2016
可以正常工作,但如果我放置fromDate: 01/01/2016
和toDate: 15/10/2016
,则不会出现任何错误。
这是我在jsFiddle中的代码。
$(function() {
$(".date-picker").datepicker({
dateFormat: 'dd/mm/yy'
});
$(".date-picker").each(function() {
$(this).add($(this).next()).wrapAll('<div class="imageInputWrapper"></div>');
});
$('input:button').click(function(e) {
$("#fDate").removeClass("red");
$("#tDate").removeClass("red");
var fromDate = $("#fDate").val();
var toDate = $("#tDate").val();
if (toDate <= fromDate) { //here only checks the day not month and year
$("#fDate").addClass("red");
$("#tDate").addClass("red");
errors++;
}
if (errors) e.preventDefault();
});
});
.imageInputWrapper {
width: 172px;
border: solid 1px white;
background-color: white;
display: flex;
align-items: center;
box-shadow: 0 2px 2px 0 #C2C2C2;
}
.red {
box-shadow: 0px 0px 2px 2px red;
}

您可以在Javascript中查看Date对象JavaScript日期库有了它,你可以做一些类似的事情
var fromDate = '04/14/2016',
toDate = '04/16/2016',
fdate = new Date(fromDate),
tdate = new Date(toDate);
if (fdate.valueOf() > tdate.valueOf()) {
console.log('Departure can not be before arrival silly. What are you a time traveler?');
}
您需要获取日期对象,然后比较值,在您的情况下,您正在进行字符串比较,而不是日期比较。
可以使用datepicker.getDate()
方法从输入字段中获取当前选定的日期对象。
$(function() {
$(".date-picker").datepicker({
dateFormat: 'dd/mm/yy'
});
$(".date-picker").each(function() {
$(this).add($(this).next()).wrapAll('<div class="imageInputWrapper"></div>');
});
$('input:button').click(function(e) {
$("#fDate").removeClass("red");
$("#tDate").removeClass("red");
var fromDate = $("#fDate").datepicker('getDate');
var toDate = $("#tDate").datepicker('getDate');
if (toDate <= fromDate) { //here only checks the day not month and year
$("#fDate").addClass("red");
$("#tDate").addClass("red");
errors++;
}
if (errors) e.preventDefault();
});
});
.imageInputWrapper {
width: 172px;
border: solid 1px white;
background-color: white;
display: flex;
align-items: center;
box-shadow: 0 2px 2px 0 #C2C2C2;
}
.red {
box-shadow: 0px 0px 2px 2px red;
}
