jquery之Django post on click with jquery 没有得到响应

我正在尝试在我的网站上设置一个按钮，当单击该按钮时，一个新的模型项目将保存到数据库中。我的代码段粘贴在下面，我将在之后讨论这个问题。

textbook.html

<script src="../../static/textchange/wishlisting.js"></script> 

...

<input type="button" id="addwishlist" value="Add to Wishlist"></input> 

wishlisting.js

$('#addwishlist').click(function() { 
$.ajax({ 
    url: '/textbook/', 
    method: 'POST', // or another (GET), whatever you need 
    data: { 
        name: request.user, 
        book: text, // data you need to pass to your function 
        click: True 
    } 
    success: function (data) { 
        // success callback 
        // you can process data returned by function from views.py 
    } 
}); 

});

View .py

def textbook(request, uisbn): 
    form4 = AddWishlist(request.POST or None) 
    ltextbook = Textbook.objects.filter(isbn = uisbn) 
    text = ltextbook[0] 
    wishlists = Wishlist.objects.filter(textbook = text) 
    listings = Posting.objects.filter(textbook = text) 
    if request.POST.get('click', False): 
        new = Wishlist(textbook = text, user = name, wish_date = datetime.now()) 
        new.save() 

根据我的理解，当我单击“添加到 Wishlist”按钮时，它应该将该 ID 与 wishlisting.html 中引用的 jquery 的 ID 相关联，然后应该加载 View 并创建数据库项目。我在思考过程中遗漏了什么？

谢谢。

请您参考如下方法:

开始的一些改变:

1.) 使用staticfiles 加载模板中的文件:

{% load staticfiles %} 
 
# You might need to change the path 
<script type="text/javascript" src="{% static 'textchange/wishlisting.js' %}"></script> 

2.) 习惯 CamelCase:

<input type="button" id="addWishList" value="Add to Wishlist" uisbn="set_value_here"></input> 

回答你的问题:

views.py:

from django.http import JsonResponse 
from django.shortcuts import get_object_or_404 
from django.views.decorators.http import require_http_methods 
 
from datetime import datetime 
 
 
@require_http_methods(['POST']) 
def textbook(request): 
    uisbn = request.POST.get('uisbn') 
    # I'm assuming all of this is correct 
    ltextbook = get_object_or_404(Textbook, isbn=uisbn) 
    if ltextbook: 
        text = ltextbook[0] 
        wishlists = Wishlist.objects.filter(textbook=text) 
        listings = Posting.objects.filter(textbook=text) 
        new = Wishlist(textbook=text, user=request.user, wish_date=datetime.now()) 
        new.save() 
        new_created = True 
    else: 
        new_created = False 
 
    data = { 
        'new_created': new_created 
    } 
    return JsonResponse(data) 

html:

$('#addWishList').click(function(e){ 
    e.preventDefault(); 
    $.ajax({ 
        type: "POST", 
        // Use the name of the url not '/textbook/' 
        url: "{% url 'textbook' %}", 
        data: { 
            "uisbn": $(this).attr("uisbn"), 
            csrfmiddlewaretoken: "{{ csrf_token }}", 
        }, 
        dataType: "json", 
        success: function(data) { 
            if (data.new_created) { 
                // Do something here 
            } else { 
                // Do something else here 
            } 
        }, 
        error: function (rs, e) { 
            alert('Sorry, there was an error.'); 
        } 
    }); 
});
