當驗證表單中有不少字段時,這時候可能但願把html的生成以及驗證邏輯放到controller中,在頁面,也許是這樣的:css
<some-form fiedls="vm.someFields" ...></some-form>html
而後,在controller中定義各個字段以及驗證。angular-formly就是爲這個需求而存在。node
在controller中,把各個字段定義在數組中:express
vm.rentalFields = [ { key:'first_name', type:'input', templateOptions:{ type:'text', label:'姓', placeholder: '輸入姓', required: true } }, ... ]
使用hideExpression字段定義隱藏的條件:npm
{ key:'under18', type:'checkbox', templateOptions:{ label:'是否不滿18歲' }, hideExpression: '!model.email' //email驗證失敗以前不顯示 }
使用validators字段自定義驗證規則:bootstrap
{ key:'license', type:'input', templateOptions:{ label:'身份證號', placeholder:'輸入身份證號' }, hideExpression: '!model.province', validators:{ driversLicense: function($viewValue, $modelValue, scope){ var value = $modelValue || $viewValue; if(value){ return validateDriversLicence(value); } }, expressionProperties:{ 'templateOptions.disabled':function($viewValue, $modelValue, scope){ if(scope.model.province == '山東省'){ return false; } return true; } } }
首先安裝:npm install angular-formly angular-formly-templates-bootstrap bootstrap api-checkapi

(function(){ 'use strict'; angular.module('formlyApp',['formly','formlyBootstrap']) })();
以factory的方式返回一個對象,包含獲取select選項的方法。ide
(function(){ 'use strict'; angular .module('formlyApp') .factory('province', province); function province(){ function getProvinces(){ return [ { "name":"山東省", "value":"山東省" }, { "name":"江蘇省", "value":"江蘇省" } ]; } return { getProvinces:getProvinces } } })();
(function(){ 'use strict'; angular .module('formlyApp') .controller('MainController', MainController); function MainController(province){ var vm = this; vm.rental = {}; vm.rentalFields = [ { key:'first_name', type:'input', templateOptions:{ type:'text', label:'姓', placeholder: '輸入姓', required: true } }, { key:'last_name', type:'input', templateOptions:{ type:'text', label:'名', placeholder:'輸入名', required:true } }, { key:'email', type:'input', templateOptions:{ type:'email', label:'郵箱', placeholder:'輸入郵箱', required:true } }, { key:'under18', type:'checkbox', templateOptions:{ label:'是否不滿18歲' }, hideExpression: '!model.email' //email驗證失敗以前不顯示 }, { key: 'province', type:'select', templateOptions:{ label:'選擇省', options: province.getProvinces() }, hideExpression: '!model.email' }, { key:'license', type:'input', templateOptions:{ label:'身份證號', placeholder:'輸入身份證號' }, hideExpression: '!model.province', validators:{ driversLicense: function($viewValue, $modelValue, scope){ var value = $modelValue || $viewValue; if(value){ return validateDriversLicence(value); } }, expressionProperties:{ 'templateOptions.disabled':function($viewValue, $modelValue, scope){ if(scope.model.province == '山東省'){ return false; } return true; } } } }, { key: 'insurance', type: 'input', templateOptions:{ label:'保險', placeholder:'輸入保險' }, hideExpression: '!model.under18 || !model.province' } ]; function validateDriversLicence(value) { return /[A-Za-z]\d{4}[\s|\-]*\d{5}[\s|\-]*\d{5}$/.test(value); } } })();
