Question

我搜索了一个术语“bi”，它应该返回一个带有初始“bi ...”的用户名。但没有显示任何内容，没有下拉列表这是我的代码。

search.html

<html>
<div class="ui-widget">
  <label for="search4">search4: </label>
  <input id="search4">
</div>

<script type="text/javascript">
$(function(){
  $("#search4").autocomplete({
    source: '/rating/searchresult/',
    minLength: 2,
  });
});
</script>
</html>

url.py

url(r'^searchresult/', 'rating.views.search_images'),

views.py

def search_images(request):
    if request.is_ajax():
        s = request.GET.get("term", '')
        search_result = UploadImage.objects.filter(user__username__icontains = s )[:20]
        search = []
        for result in search_result:
            json_d = {}
            json_d['id'] = result.id
            json_d['name'] = result
            json_d['value'] = result
            search.append(json_d)
        data = m_json.dumps(search)
    else:
        data = 'error'
    mimetype = 'application/json'
    return HttpResponse(data, mimetype)

如果我搜索一个值，Ajax不响应并且在下拉列表中没有返回任何内容，而该术语在URl中传递

[04/Aug/2016 08:48:46] "GET /rating/searchresult/?term=bi HTTP/1.1" 200 2661

我无法理解Ajax或Django的问题在哪里 Also my content type is text html see here

好的，从技术上来说，你做错了。

source的{{1}}属性需要一个字符串或数据数组，您希望在输入字段中为用户提供自动完成选项。

现在您要做的就是在autocomplete url views.py中的source中简单地提供与特定视图类或方法相对应的autocomplete实际上您需要做的是通过点击ajax来获得url响应，然后您将从该网址对应的类/方法获得所需的响应。

现在，您将此response提供给autocomplete的来源

请在此处查看source的{{1}}如何运作 - ＆gt; http://api.jqueryui.com/autocomplete/#option-source

autocomplete的官方文档 - ＆gt; http://api.jquery.com/jquery.ajax/

ajax的文档 - ＆gt; https://api.jquery.com/jquery.get/

所以你的javascript文件看起来像这样：

$.get()

现在，如果它成功运行，那么您将在$(document).on('ready', function(){ populateSearchFieldList(); // all other code according to your needs }); function populateSearchFieldList() { var url = "/rating/searchresult/"; $.get(url, function(response) { // console.log("Success..!!"); console.log(response); // now in views.py, you've returned a list in which every // object has an id, name and value but you // want only the names in your autocomplete. So for that, first // you'll have to create a list of just the names and then feed // that list to the source of autocomplete. Like this var searchFieldOptions = []; var i = 0; $.each(response,function(){ searchFieldOptions.push(response[i].name); i++; }); // and now make the source of autocomplete as // searchFieldOptions like this $(function(){ $("#search4").autocomplete({ source: searchFieldOptions, minLength: 2, }); }); }); }函数中收到的response中包含所需数据。现在，您可以将此success用作response的{{1}}，如果它只是一个列表，或者可以进一步修改此source并形成所需内容的autocomplete根据您的要求。

Django没有响应ajax自动完成
