添加自定义消息以淘汰所需的验证

Question

我已向我的 observable 添加了必需的验证。如何将消息更改为“此字段为必填项”以外的内容。

self.Leaving = ko.observable(leaving).extend({
    required:   {
        onlyIf: function() { return self.Status() == 10; }
    }              
});

Answer 1

self.Leaving = ko.observable(leaving).extend({
    required:   {
        onlyIf: function() { return self.Status() == 10; },
        message: 'Custom message'
    }
});
