avalon内置了强大的表单验证功能，它需要结合ms-duplex, ms-validate, ms-rules这个三个指令一起使用。
验证规则定义在avalon.validators对象中, 为一个个带有message与get属性的对象.
1 avalon.shadowCopy(avalon.validators, { 2 pattern: { 3 message: ‘必须匹配{{pattern}}这样的格式‘, 4 get: function (value, field, next) { 5 var elem = field.dom 6 var data = field.data 7 if (!isRegExp(data.pattern)) { 8 var h5pattern = elem.getAttribute("pattern") 9 data.pattern = new RegExp(‘^(?:‘ + h5pattern + ‘)$‘) 10 } 11 next(data.pattern.test(value)) 12 return value 13 } 14 }, 15 digits: { 16 message: ‘必须整数‘, 17 get: function (value, field, next) {//整数 18 next(/^\-?\d+$/.test(value)) 19 return value 20 } 21 } 22 })
手动调用验证并根据点击不同按钮提交不同网址的例子
<!DOCTYPE html>

avalon.validators.gtOne = {
message: ‘必须数字并大于1‘,
get: function (value, field, next) {
//想知道它们三个参数是什么,可以console.log(value, field,next)
var ok = Number(value) > 1
next(ok)
return value
}
}
var greasons = []
var vm = avalon.define({
$id: "test",
aaa: ‘‘,
url: ‘javascript:void(0)‘,
message: ‘‘,
submit: function (url) {//submit是真正的验证方法,通过点击时手动验证
vm.validate.onManual()
setTimeout(function () {
if (greasons.length) {
var a = greasons.map(function (el) {
return ‘<p>‘ + el.getMessage() + ‘</p>‘
})
vm.message = a.join(‘‘)//打印所有错误
vm.url = ‘javascript:void(0)‘
} else {
greasons = []
vm.message = ‘‘
vm.url = url
}
})
},
validate: {
//禁止提交时自动验证
validateAllInSubmit: false,
//这个是用来占位的
onManual: avalon.noop,
//这个转移到sumbit方法
onValidateAll: function (reasons) {
greasons = reasons.concat()
}
}
})
