我已经返回了一个验证组来验证我的输入,这些输入触发了提交按钮,我希望通过验证模糊事件来触发相应的验证,而不是全部。
例如:
HTML:
<form role="form" submit.delegate="welcome()" validate.bind="validation">
<div class="form-group">
<label for="fn">First Name</label>
<input type="text" value.bind="firstName & updateTrigger:'blur'" class="form-control" id="fn" placeholder="first name" />
<span>${firstName}</span>
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
ViewModel中的验证规则:
this.validation = validation.on(this)
.ensure('firstName')
.isNotEmpty()
.hasMinLength(3)
.hasMaxLength(10);
由于我写了updateTrigger:'blur'
,所以没有任何验证被触发。
删除updateTrigger:'blur'
后,所有验证都可以正常运行。
要求:
我希望一旦输入框失去焦点(模糊被触发),然后验证(&#39; firstname&#39;不会触发(其他属性)的其他验证。
提前致谢。

aurelia-validation alpha现在支持此功能。看看这篇博文:https://www.danyow.net/aurelia-validation-alpha/

Aurelia的验证在2016年末更新,包括 changeOrBlur validateTrigger
选项,我认为这应该是新的默认选项。以下是如何使用它:
constructor(controller) {
this.controller = controller;
controller.validateTrigger = validateTrigger.changeOrBlur;
// controller.validateTrigger = validateTrigger.blur; (default)
// controller.validateTrigger = validateTrigger.change;
// controller.validateTrigger = validateTrigger.changeOrBlur;
// controller.validateTrigger = validateTrigger.manual;
}
