jQuery验证-如果选中复选框,Textbox需要数据
我有一个复选框-jQuery验证-如果选中复选框,Textbox需要数据,jquery,validation,asp.net-mvc-4,jquery-validate,Jquery,Validation,Asp.net Mvc 4,Jquery Validate,我有一个复选框-HasRaffle,如果选中了HasRaffle,则需要一个文本框-RaffleItem来包含数据。我该怎么做?我以前从未做过自己的jQuery验证。这是我尝试的,但根本不起作用。我离你很近吗 $("#donationEventForm").validate({ rules: { RaffleItem: { required: function () { if ($("#HasRaffle").is(
HasRaffle
,如果选中了HasRaffle
,则需要一个文本框-RaffleItem
来包含数据。我该怎么做?我以前从未做过自己的jQuery验证。这是我尝试的,但根本不起作用。我离你很近吗
$("#donationEventForm").validate({
rules: {
RaffleItem: {
required: function () {
if ($("#HasRaffle").is(":checked")) {
if ($("#RaffleItem").val === '') {
return true;
} else {
return false;
}
} else {
return false;
}
},
messages: {
required: "This is a test!!"
}
}
}
});
编辑:这是我的观点
@using (Html.BeginForm("Create", "DonationEvent", FormMethod.Post, new {id = "donationEventForm"})) {
@Html.AntiForgeryToken()
@Html.ValidationSummary(false)
<div class="form-field">
@Html.LabelFor(model => model.Charity)
@Html.TextBoxFor(model => model.Charity)
@Html.ValidationMessageFor(model => model.Charity)
</div>
<div class="form-field">
@Html.LabelFor(model => model.StartDate)
@Html.TextBoxFor(model => model.StartDate, new {@class = "datepicker"})
@Html.ValidationMessageFor(model => model.StartDate)
</div>
<div class="form-field">
@Html.LabelFor(model => model.EndDate)
@Html.TextBoxFor(m => m.EndDate, new {@class = "datepicker"})
@Html.ValidationMessageFor(model => model.EndDate)
</div>
<div class="form-field">
@Html.Label("Raffle?")
@Html.CheckBox("HasRaffle", true)
</div>
<div class="form-field">
@Html.LabelFor(model => model.RaffleItem)
@Html.TextBoxFor(model => model.RaffleItem)
@Html.ValidationMessageFor(model => model.RaffleItem)
</div>
@Html.TextBoxFor(model => model.GLCode, new {@type = "hidden"})
@Html.TextBoxFor(model => model.TransactionDescription, new {@type = "hidden"})
@Html.TextBoxFor(model => model.CreatedBy, new {@type = "hidden"})
<div class="form-field-buttons">
<input type="submit" value="Create" />
<input type="button" value="Cancel" onclick="location.href='../Home/Index'"/>
</div>
}
@使用(Html.BeginForm(“Create”、“DonationEvent”、FormMethod.Post、new{id=“donationEventForm”})){
@Html.AntiForgeryToken()
@Html.ValidationSummary(false)
@LabelFor(model=>model.Charity)
@Html.TextBoxFor(model=>model.Charity)
@Html.ValidationMessageFor(model=>model.Charity)
@LabelFor(model=>model.StartDate)
@Html.TextBoxFor(model=>model.StartDate,new{@class=“datepicker”})
@Html.ValidationMessageFor(model=>model.StartDate)
@LabelFor(model=>model.EndDate)
@TextBoxFor(m=>m.EndDate,新的{@class=“datepicker”})
@Html.ValidationMessageFor(model=>model.EndDate)
@Html.Label(“抽奖?”)
@复选框(“HasRaffle”,true)
@LabelFor(model=>model.RaffleItem)
@Html.TextBoxFor(model=>model.RaffleItem)
@Html.ValidationMessageFor(model=>model.RaffleItem)
@Html.TextBoxFor(model=>model.GLCode,新的{@type=“hidden”})
@Html.TextBoxFor(model=>model.TransactionDescription,新的{@type=“hidden”})
@Html.TextBoxFor(model=>model.CreatedBy,new{@type=“hidden”})
}
您需要使用addMethod添加自定义规则
jQuery.validator.addMethod('checkRaffle', function(value, element){
if ($("#HasRaffle").is(":checked")) {
if (value === '') {
return false;
} else {
return true;
}
} else {
return true;
}
}, 'Please write something')
那么规则看起来是这样的:
rules: {
'RaffleItem': {
'checkRaffle' : true
}
}
这段代码没有经过测试(因为我看不到您的DOM,所以可能无法工作),但是如果您能看到我的代码背后的逻辑,您可能可以调试您的代码 这只是图片的一半。还显示表单的HTML。
