当形式与角提交更改类和显示信息 [英] Change classes and display message when form is submitted with Angular
问题描述
我使用ngMessages与我的表单验证显示错误消息,这是工作。
现在我的问题是,当我提交表单我想从有效(绿框)改变类为正常状态,这是对刚刚投入CSS。此外,如果所有的字段都有效的文本消息应显示上述表单,表单已经发出,但它似乎并没有与$有效的合作。
几秒钟后,信息消失。
我的code

。无效场{
边框:1px的固体红色;
}
.valid场{
边框:1px的固体绿色;
}
.error {

}
.sent {
颜色:绿色;
}

更新
我怕你不能做,你直接需要的东西,因为如果你改变的条件有2个国家将互相冲突:
的用户正确填写表单并提交的VS的用户preSS提交,然后正确填写一个字段的
在第二个案例字段不会显示有效场
绿色边框。
你应该做的是做哪些检查的有效字段功能,并执行它提交,然后设置一个标志上真正
一类的形式对全球这将覆盖您当前的有效
/无效状态
这里是工作液
//验证美国
$ scope.validateSuccessSubmit =功能(){
如果($ scope.contactForm.nameField $有效和放大器;&安培;
。$ scope.contactForm.emailField $有效和放大器;&安培;
$ scope.contactForm。$提交){
$ scope.formCompleted =真;
} };
<! - 表 - >
<形成NOVALIDATE NAME =联系形式NG-CLASS ={'的形式完成的':formCompleted}>
/ * *的CSS /
.FORM完成的输入{
边框:1px的固体深灰;
}
的 previous不正确的答案:的
只需添加!$提交
在有效场
类条件
纳克级={'无效场:。contactForm.nameField $感动||联系形式提交$,
'有效场:contactForm.nameField $有效和放大器;&安培; !联系形式。$}提交//和NG-CLASS ={'无效场:。contactForm.emailField $感动||联系形式提交$,

I'm using ngMessages to display error messages with my form validation and this is working.
Now my problem is when I submit the form I want to change the classes from being valid (green border) to their normal state, which is just css on the inputs. Also if all the fields are valid a text message should display above the form that the form has been sent but it doesn't seem to be working with the $valid.
After a few seconds the message disappears.
my code
css
input {
background-color: #fff;
border: 1px solid darkgray;
margin-top: 20px;
width: 400px;
height: 45px;
padding: 0 10px;
}
.invalid-field {
border: 1px solid red;
}
.valid-field {
border: 1px solid green;
}
.error {
color: red;
}
.sent {
color: green;
}
html/angular
<form novalidate name="contactForm">
<div ng-messages="contactForm.$valid" ng-if="contactForm.$submitted">
<div ng-message="valid">
<span class="sent">Your message has been sent!</span>
</div>
</div>
<input ng-class="{'invalid-field': contactForm.nameField.$touched || contactForm.$submitted, 'valid-field': contactForm.nameField.$valid}"
type="text" name="nameField" placeholder="Full name*"
ng-model="contactName"
minlength="2"
required >
<div ng-messages="contactForm.nameField.$error" ng-if="contactForm.$submitted || contactForm.nameField.$touched">
<div ng-message="required">
<span class="error">Name is required</span>
</div>
<div ng-message="minlength">
<span class="error">Name must be 2 characters long</span>
</div>
</div>
<input ng-class="{'invalid-field': contactForm.emailField.$touched || contactForm.$submitted, 'valid-field': contactForm.emailField.$valid}"
type="email" name="emailField" placeholder="Email*"
ng-model="contactEmail"
required>
<div ng-messages="contactForm.emailField.$error" ng-if="contactForm.$submitted || contactForm.emailField.$touched">
<div ng-message="required"><span class="error">Email is required</span></div>
<div ng-message="email"><span class="error">Email is not valid</span></div>
</div>
<button class="send-btn" type="submit">Send form</button>
</form>
Update
I'm afraid that you can't do what you need directly, because if you change the conditional there are 2 states which will conflict with each other:
The user fills the form correctly and submits VS The user press Submit, then fills a field correctly
In the second case the field won't be show the valid-field
green border.
What you should do is make a function which checks the valid fields, and execute it on the submit, then set a flag on true
for a class global on your form which will override your current valid
/invalid states
Here is the working solution
//Validate States
$scope.validateSuccessSubmit = function(){
if($scope.contactForm.nameField.$valid &&
$scope.contactForm.emailField.$valid &&
$scope.contactForm.$submitted) {
$scope.formCompleted = true;
}
};
<!-- Form -->
<form novalidate name="contactForm" ng-class="{'form-completed' : formCompleted}">
/*CSS*/
.form-completed input{
border: 1px solid darkgray;
}
Previous incorrect answer:
Just add the !$submitted
condition on the valid-field
class
ng-class="{'invalid-field': contactForm.nameField.$touched || contactForm.$submitted,
'valid-field': contactForm.nameField.$valid && !contactForm.$submitted}"
//And
ng-class="{'invalid-field': contactForm.emailField.$touched || contactForm.$submitted,
'valid-field': contactForm.emailField.$valid && !contactForm.$submitted}"
