AngularJS uses angular-formly for form validation_AngularJS

WBOYOriginal: 2016-05-16 15:23:161450browse

When there are many fields in the verification form, you may want to put the HTML generation and verification logic in the controller. On the page, it may look like this:

<some-form fiedls="vm.someFields" ...></some-form>

Then, define each field and validation in the controller. angular-formly exists for this requirement.

In the controller, define each field in the array:

vm.rentalFields = [
{
key:'first_name',
type:'input',
templateOptions:{
type:'text',
label:'姓',
placeholder: '输入姓',
required: true
}
},
...
]

Use the hideExpression field to define hiding conditions:

{
key:'under18',
type:'checkbox',
templateOptions:{
label:'是否不满18岁'
},
hideExpression: '!model.email' //email验证失败之前不显示
}

Use the validators field to customize validation rules:

{
key:'license',
type:'input',
templateOptions:{
label:'身份证号',
placeholder:'输入身份证号'
},
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 == '山东省'){
return false;
}
return true;
}
}
}

First install: npm install angular-formly angular-formly-templates-bootstrap bootstrap api-check

Demo’s file structure:

css/
.....style.css
node_modules/
scripts/
.....MainController.js
.....provinces.js [Provides selection options, relevant provinces]
