• 循序渐进Python3(十三) --0-- django之form表单


    django为我们提供了form表单验证功能,下面来学习一下:

    创建了django项目之后,创建app。

     配置urls:
    1. from django.conf.urls import url
    2. from django.contrib import admin
    3. from myapp01 import views
    4. urlpatterns = [
    5. url(r'^admin/', admin.site.urls),
    6. url(r'^login/', views.login),
    7. ]
    配置views(app01.views):
    1. from django.shortcuts import render
    2. from django import forms
    3. # Create your views here.
    4. class InputForm(forms.Form):
    5. # 下面使用的变量名必须和html中input标签的name值相同
    6. username = forms.CharField(required=True)
    7. password = forms.CharField(required=True)
    8. def login(request):
    9. if request.method == 'POST':
    10. obj = InputForm(request.POST)
    11. ret = obj.is_valid()
    12. print(ret,obj.data)
    13. if ret:
    14. print(obj.clean())
    15. else:
    16. print(obj.errors)
    17. return render(request, 'login.html')

    配置tamplates(index.html):
    1. <!DOCTYPE html>
    2. <html lang="en">
    3. <head>
    4. <meta charset="UTF-8">
    5. <title>Title</title>
    6. </head>
    7. <body>
    8. <div>
    9. <div>
    10. <input type="text" name="username" />
    11. </div>
    12. <div>
    13. <input type="password" name="password" />
    14. </div>
    15. <input type="button" value="提交" onclick="DoSubmit();"/>
    16. </div>
    17. <script src="/static/jquery-2.1.4.min.js"></script>
    18. <script>
    19. function DoSubmit() {
    20. var input_dic = {};
    21. $('input').each(function () {
    22. var v = $(this).val();
    23. var n = $(this).attr('name');
    24. input_dic[n] = v;
    25. });
    26. console.log(input_dic);
    27. $.ajax({
    28. url:'/login/',
    29. type:'POST',
    30. data:input_dic,
    31. success: function (rdata) {
    32. console.log(rdata);
    33. },
    34. error: function () {
    35. }
    36. })
    37. }
    38. </script>
    39. </body>
    40. </html>

     提交之后就可以获取输入的内容。
