When there are many fields in the validation form, you may want to put the HTML generation and validation logic in the controller, on the page, perhaps:

<some-form fiedls= "Vm.somefields" ...></some-form>

Then, define the individual fields in the controller and verify. Angular-formly is the existence of this demand.


In the controller, define each field in the array:

Vm.rentalfields = [    {        key:' first_name ',        type:' input ',        templateoptions:{            Type:' text ',            label:' last name'            ,' Enter last Name ',            true        }    },    ...]


Use the Hideexpression field to define hidden conditions:

{    key:' Under18 ',    type:' checkbox ',    templateoptions:{        Label:' is under 18 years old '     },     // Email verification fails before it is displayed }

Use the validators field to customize validation rules:

{key:' License ', type:' Input ', templateoptions:{Label:' ID number ', placeholder:' Enter your ID number '}, Hideexpression:'!model.province ', validators:{driverslicense:function($viewValue, $modelValue, scope) {varValue = $modelValue | |$viewValue; if(value) {returnvalidatedriverslicence (value); }}, expressionproperties:{' Templateoptions.disabled ':function($viewValue, $modelValue, scope) {if(scope.model.province = = ' Shandong province '){                    return false; }                return true; }        }    }

First install: NPM install angular-formly angular-formly-templates-bootstrap Bootstrap Api-check

App.js 

(function() {    ' use strict ';    Angular.module (' Formlyapp ', [' formly ', ' Formlybootstrap '])});

Province.js

Returns an object in factory that contains the method that gets the Select option.

(function(){    ' Use strict '; Angular. Module (' Formlyapp '). Factory (' Province ', province); functionProvince () {functiongetprovinces () {return [                {                    "Name": "Shandong Province",                    "Value": "Shandong Province"                },                {                    "Name": "Jiangsu Province",                    "Value": "Jiangsu Province"                }            ]; }        return{getprovinces:getprovinces}}}) ();

Maincontroller.js 

(function(){    ' Use strict '; Angular. Module (' Formlyapp '). Controller (' Maincontroller ', Maincontroller); functionMaincontroller (province) {varVM = This; Vm.rental= {}; Vm.rentalfields=[{key:' First_Name ', type:' Input ', templateoptions:{type:' Text ', Label:Last Name, placeholder:' Enter last Name ', Required:true}}, {key:' Last_Name ', type:' Input ', templateoptions:{type:' Text ', Label:Extension, placeholder:' Input name ', Required:true}}, {key:' Email ', type:' Input ', templateoptions:{type:' Email ', Label:Mailbox, placeholder:' Enter mailbox ', Required:true}}, {key:' Under18 ', type:' checkbox ', templateoptions:{Label:' Are you under 18?
