avalon2对于非必填项的验证 #1708
Comments

不是必填的，它也不用检测是什么内容吧！ |
|
一个字段可以不填，但如果要填的话一定要是合法的数字 |
|
那自己自定义规则 |
<!DOCTYPE html>
<html>
<head>
<title>ms-validate</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<script src="../dist/avalon.js"></script>
<script>
avalon.validators.aaa = {
message: '必须数字并大于0',
get: function (value, field, next) {//数值
var ok = (value === '' || (Number(value) > 0))
next(ok)
return value
}
}
var vm = avalon.define({
$id: "test",
aaa: '',
validate: {
onError: function (reasons) {
reasons.forEach(function (reason) {
console.log(reason.getMessage())
})
},
onValidateAll: function (reasons) {
if (reasons.length) {
console.log('有表单没有通过')
} else {
console.log('全部通过')
}
}
}
})
</script>
</head>
<body ms-controller="test">
<form class="cmxform" ms-validate="@validate" >
<fieldset>
<legend>自定义规则</legend>
<p>
<input
ms-duplex="@aaa"
ms-rules="{aaa: true}"
>
</p>
</fieldset>
<p>
<input class="submit" type="submit" value="提交">
</p>
</fieldset>
</form>
</body>
</html> |

如果一个input是非必填的，且只能为数字，大于0等限制。avalon2的验证机制仍会对为空时进行规则判断。建议添加required:false 或其他可以解决该类问题的方案。
