我有一个班级:
Model.Feedback.Data = function () {
var self = this;
self.Name = ko.observable('').extend({
pattern: {
params: /^[A-Za-z]+[A-Za-z\s]*$/,
message: 'Invalid name'
}
});
self.Email = ko.observable('').extend({
pattern: {
params: /^[a-zA-Z0-9!#$%&'*+/=?^`{|}~]+(?:[\._-][a-zA-Z0-9!#$%&'*+/=?^`{|}~]+)*@(?:[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?$/,
message: 'Invalid e-mail'
},
maxLength: {
params: 256,
message: 'Long email'
}
});
return this;
};
我有一个HTML代码:
<form class="form-additem-checkin" data-bind="submit: send">
<!--ko with: Data-->
<div class="form-additem-group-row">
<div class="form-additem-group-row__col form-additem-group-row__col_label"><div class="form-additem-group__label">E-mail</div></div>
<div class="form-additem-group-row__col form-additem-group-row__col_field">
<input type="text" class="field field_type2 input--full" placeholder="You e-mail" data-bind="textInput: Email" />
<div class="form-additem-group-row__error" data-bind="validationMessage: Email"></div>
</div>
</div>
<div class="form-additem-group-row">
<div class="form-additem-group-row__col form-additem-group-row__col_label"><div class="form-additem-group__label">Name</div></div>
<div class="form-additem-group-row__col form-additem-group-row__col_field">
<input type="text" class="field field_type2 input--full" placeholder="You name" data-bind="textInput: Name" />
<div class="form-additem-group-row__error" data-bind="validationMessage: Name"></div>
</div>
</div>
<!--/ko-->
<div class="form-additem-auth__button">
<button type="submit" class="btn btn--green form-additem-button">Send</button>
</div>
</form>
现在,如果您在电子邮件字段中输入test @ a,您将立即收到错误消息。
在失去场地焦点后,我该怎么做才能检查场地?
