我有三个文本框BirthDate
,JoiningDate
& LeavingDate
。
现在我想要的是: -
Joining date
和Leaving date
不得大于Birthdate
Leaving Date
不得大于Joining Date
和BirthDate
我使用了DatePicker。
这是JS代码: -
$(function () {
$("[id$=mainContent_txtdateofbirth], [id$=mainContent_txtdoj], [id$=mainContent_txtdol]").datepicker({
textboxImageOnly: true,
textboxImage: 'images/calendar.png',
changeMonth: true,
changeYear: true,
dateFormat: "yy / mm / dd",
yearRange: "-40:+0",
maxDate: new Date(),
});
});
三个文本框是: -
<asp:TextBox ID="txtdateofbirth" CssClass="form-control" runat="server" ValidationGroup="AddNew"></asp:TextBox>
<asp:TextBox ID="txtdoj" CssClass="form-control" runat="server" ValidationGroup="AddNew"></asp:TextBox>
<asp:TextBox ID="txtdol" CssClass="form-control" runat="server" ValidationGroup="AddNew"></asp:TextBox>
更新的ASPX代码: -
<tr>
<td style="vertical-align: top;">
<label class="control-label" for="dob">Date of Birth</label></td>
<td>
<div class="control-group">
<div class="controls">
<asp:TextBox ID="txtdateofbirth" CssClass="form-control" autocomplete="off" runat="server" ValidationGroup="AddNew"></asp:TextBox>
<asp:RequiredFieldValidator ID="reqdob" runat="server" CssClass="error-class" ControlToValidate="txtdateofbirth" ErrorMessage="Please select the date of birth" ValidationGroup="AddNew"></asp:RequiredFieldValidator>
</div>
</div>
</td>
</tr>
<tr>
<td style="vertical-align: top;">
<label class="control-label" for="subject">Date of Join</label></td>
<td>
<div class="control-group">
<div class="controls">
<asp:TextBox ID="txtdoj" Wrap="true" CssClass="form-control" autocomplete="off" runat="server" ValidationGroup="AddNew"></asp:TextBox>
<asp:RequiredFieldValidator ID="reqdoj" CssClass="error-class" runat="server" ControlToValidate="txtdoj" ErrorMessage="Please add the date of joining" ValidationGroup="AddNew"></asp:RequiredFieldValidator>
</div>
</div>
</td>
</tr>
<tr>
<td style="vertical-align: top;">
<label class="control-label" for="subject">Date of Leaving</label></td>
<td>
<div class="control-group">
<div class="controls">
<asp:TextBox ID="txtdol" CssClass="form-control" autocomplete="off" runat="server" ValidationGroup="AddNew"></asp:TextBox>
</div>
</div>
</td>
</tr>

验证功能
var validateData = function () {
var bday = $('#birthdate').val();
var jday = $('#joiningdate').val();
var lday = $('#leavingdate').val();
if (bday && jday && bday > jday) {return}
if (bday && lday && bday > lday) {return}
if (jday && lday && jday > lday) {return}
return true;
};
在可以显示什么错误消息之后,被调用datepicker的onClose事件。随意更改错误显示方法。
onClose: function () {
validateData() ? $('#errormsg').hide() : $('#errormsg').show();
}

要向错误消息添加一些css,请将类添加到
<div id="errormsg" class="error-msg">Invalid date</div>
然后您可以将display: none;
移至您的css

已完成的JS Fiddle是here
首先让我假设您实际上意味着以下
而不是相反,如果我错了,请纠正我。
现在寻求解决方案,您可以使用jQuery Validation Plugin实现此目的。只需在插件中添加自定义验证功能,然后根据它验证表单。请参阅示例代码
<form id="myForm">
<p>Date Of Birth:
<input type="text" name="datepicker_dob" id="datepicker_dob" />
</p>
<p>Date Of Joining:
<input type="text" name="datepicker_doj" id="datepicker_doj" />
</p>
<p>Date Of Leaving:
<input type="text" name="datepicker_dol" id="datepicker_dol" />
</p>
<button type="button" id="saveButton">Save</button>
</form>
像这样初始化你的日期时间选择器
$(document).ready(function() {
$("[id$=datepicker_dob],[id$=datepicker_doj],[id$=datepicker_dol]" ).datepicker({
// add this option when you initialise the datetime picker, this will
// validate date based on our custom validation rule when we select a date
onSelect:function(){
$(this).valid();
}
});
});
接下来是添加自定义验证器功能
$.validator.addMethod("dateValidatorLE", function(value, element, params) {
var isDateValid = true;
$(params).each(function(i) {
// alert($(params[i]).val());
isDateValid &= (Date.parse(value) > Date.parse($(params[i]).val()))
});
return this.optional(element) || isDateValid;
}, $.validator.format('general error message'));
验证您的表单
$('#myForm').validate({
rules: {
datepicker_doj: {
dateValidatorLE: ['#datepicker_dob']
},
datepicker_dol: {
dateValidatorLE: ['#datepicker_dob', '#datepicker_doj']
}
},
messages: {
datepicker_doj: {
dateValidatorLE: 'DOJ must be greater than DOB'
},
datepicker_dol: {
dateValidatorLE: 'DOL must be greater that DOJ and DOB'
}
},
onkeyup: function(e) {
this.element(e);
}
});
请告诉我这是否对您有所帮助。

我真的不明白你希望代码看起来如何。无论如何,这是一个简单的验证,如果你想要你可以放入一个函数:
function validateMyForm() {
return ($('#txtdoj').val() <= $('#txtdateofbirth').val()
&& $('#txtdol').val() <= $('#txtdateofbirth').val()
&& $('#txtdol').val() <= $('#txtdoj').val()
&& $('#txtdol').val() <= $('#txtdateofbirth').val());
}
如果表单有效,则返回true;如果表单不是
,则返回false
