avalon2表单验证,非必填字段在不填写的时候不能通过验证

代码

<script>
    var vm = avalon.define({
        $id: "validate1",
        aaa : "",
        validate: {
            onError: function(reasons) {
                reasons.forEach(function(reason) {
                    console.log(reason.getMessage())
                })
            },
            onValidateAll: function(reasons) {
                if(reasons.length) {
                    alert(reasons[0].getMessage())
                } else {
                    alert('全部通过')
                }
            }
        }
    })
</script>
<div ms-controller="validate1">
    <form ms-validate="@validate">
        <input ms-duplex="@aaa" placeholder="url" ms-rules='{url:true}'>
        <p><input type="submit" value="submit"/></p>
    </form>
</div>

查看源码 avalon/src/directives/duplex/addValidateField.js 中 validate 方法中

            var next = function (a) {
                if (field.norequired && value === '') {
                    a = true
                }
                ......
            }

有判断 field.norequired 是否为非必填字段 ,但貌似 norequired 属性从未赋值过

我的解决办法

在源码 avalon/src/directives/duplex/addValidateField.js 改造

代码如下

module.exports = function addField(node, vnode) {
    var field = node.__ms_duplex__
    var rules = vnode['ms-rules']
    if (rules && !field.validator) {
        while (node && node.nodeType === 1) {
            var validator = node._ms_validator_
            if (validator) {
                if (rules['required'] === undefined || rules['required'] === false)
                    field.norequired = true;
                field.rules = rules
                field.validator = validator
                if (avalon.Array.ensure(validator.fields, field)) {
                    validator.addField(field)
                }
                break
            }
            node = node.parentNode
        }
    }
}

新增了 这么一段 给 norequired 属性赋值 解决了非必填验证的问题

if (rules['required'] === undefined || rules['required'] === false)
    field.norequired = true;

但不知道此方法是否是合理？

等下一个版本，我添加一个新的norequired规则
