我正在尝试创建一个用户输入电子邮件的表单。通常,浏览器会显示电子邮件的验证错误(空字段或不正确的格式)。
使用基本表单示例,一切都正确显示:
<form action="/notify-email/add/" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="Submit" />
</form>
在我的情况下,如果没有验证错误,我使用ajax请求来保存电子邮件并显示带有感谢信息的模态。但是如果存在验证错误,我只能在悬停时看到它们。
此外,即使验证中存在错误,也会显示模态。
这是我的models.py:
from django.db import models
class NotifyEmail(models.Model):
email = models.EmailField(max_length=255)
date_added = models.DateField(auto_now_add=True)
time_added = models.TimeField(auto_now_add=True)
def __str__(self):
return self.email
这是基于模型的表格:
from django import forms
from landing.models import NotifyEmail
class NotifyEmailForm(forms.ModelForm):
class Meta:
model = NotifyEmail
fields = ["email"]
def __init__(self, *args, **kwargs):
super(NotifyEmailForm, self).__init__(*args, **kwargs)
self.fields['email'].widget = forms.EmailInput(attrs={'placeholder': 'Email',
'required': True})
我的views.py:
from django.shortcuts import render
from django.http import JsonResponse
from .forms import NotifyEmailForm
def add_notify_email(request):
if request.method == "POST":
form = NotifyEmailForm(request.POST)
if form.is_valid():
form.save(commit=True)
print("Email Added.")
return JsonResponse({'msg': 'Data saved'})
else:
print("Error in Notify Form")
return JsonResponse({"msg": "Error"})
else:
form = NotifyEmailForm()
return render(request, "landing/home.html", {"form": form})
我的urls.py:
from django.conf.urls import url
from . import views
urlpatterns = [url(r'^notify-email/add/$', views.add_notify_email)]
html代码:
<div class="container-fluid" id="comingSoon">
<div class="container">
<h2>Coming Soon</h2>
<h5>If you want to get notified when we go live, please enter your email below.</h5>
</div>
<div class="container" id="notify-email-container">
<form action="/notify-email/add/" method="post" id="notify-email-form">
{% csrf_token %}
<div class="form-group row">
<div class="col-sm-10" id="email-input-container">
<input class="form-control" type="email" name="email" placeholder="Your email...." maxlength="255" required id="id_email" />
</div>
{% for error in form.email.errors %}
<div class="alert alert-error">
<p class="field-error"><i class="fa fa-exclamation-circle" aria-hidden="true"></i>{{ error|escape }}</p>
</div>
{% endfor %}
<div class="col-sm-2">
<button type="button" class="btn btn-block btn-primary" onclick="addNotifyEmail()" id="submit-notify-email">Notify Me</button>
</div>
</div>
</form>
</div>
</div>
<div class="modal" tabindex="-1" role="dialog" id="thanks">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Thank you</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>We would like to thank you for your interest.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<script>
function addNotifyEmail(e){
var notifyEmailForm = $("#notify-email-form");
var thanksModal = $("#thanks");
$.ajax({
type: 'POST',
url: '/notify-email/add/',
data: notifyEmailForm.serialize(),
success: function(res){
thanksModal.modal('show')}
})}
</script>

我不确定我是否理解你的问题。
所以,问题是如果你有一些验证错误,它们会出现在你的错误中。 div,只有你徘徊它们?如果是,那么它与您的css
或javascript
相关。检查脚本和css文件。也许在某处您触发了.field-error
元素。
关于模态外观。好吧,这是关于你的AJAX
请求。
在您的代码中,无论如何,当HTTP Request
将获得200代码的答案时,您将显示您的模态。这意味着,即使您没有有效的表单,也会向JsonResponse
发回一些msg并将其带回您的页面,这意味着您的脚本每次都会触发success
,这就是您的原因所在莫代尔正在出现。
不要只发送一些JsonResponse({"msg": "Error"})
,而是尝试使用它来处理错误。
function addNotifyEmail(e){
var notifyEmailForm = $("#notify-email-form");
var thanksModal = $("#thanks");
$.ajax({
type: 'POST',
url: '/notify-email/add/',
data: notifyEmailForm.serialize(),
success: function(res){
if(res.msg !== "Error") {
thanksModal.modal('show');
}
}
})}
