Django：如何从模板中调用视图函数？

I have a question on how to call a view function from a template HTML button? Like an onclick function? Here is the template:

我有一个关于如何从模板HTML按钮调用视图函数的问题？像onclick函数一样？这是模板：

<input id="submit" type="button" onclick="xxx" method="post" value="Click" />

And the views.py is:

而views.py是：

def request_page(request):
    ...do something...
    return render_to_response("/directory.html", {})

Thank you very much.

非常感谢你。

One option is, you can wrap the submit button with a form

一个选项是，您可以使用表单包装提交按钮

Something like this:

像这样的东西：

<form action="{% url path.to.request_page %}" method="POST">
    <input id="submit" type="button" value="Click" />
</form>

(remove the onclick and method)

（删除onclick和方法）

If you want to load a specific part of the page, without page reload - you can do

如果您想加载页面的特定部分，而无需重新加载页面 - 您可以这样做

<input id="submit" type="button" value="Click" data_url/>

and on a submit listener

并在提交监听器上

$(function(){
     $('form').on('submit', function(e){
         e.preventDefault();
         $.ajax({
             url: $(this).attr('action'),
             method: $(this).attr('method'),
             success: function(data){ $('#target').html(data) }
         });
     });
});

Assuming that you want to get a value from the user input in html textbox whenever the user clicks 'Click' button, and then call a python function (mypythonfunction) that you wrote inside mypythoncode.py. Note that "btn" class is defined in a css file.

假设您想要在用户单击“Click”按钮时从html文本框中的用户输入获取值，然后调用您在mypythoncode.py中编写的python函数（mypythonfunction）。请注意，“btn”类是在css文件中定义的。

inside templateHTML.html:

在templateHTML.html中：

<form action="#" method="get">
 <input type="text" value="8" name="mytextbox" size="1"/>
 <input type="submit" class="btn" value="Click" name="mybtn">
</form>

inside view.py:

在view.py内：

import mypythoncode

def request_page(request):
  if(request.GET.get('mybtn')):
    mypythoncode.mypythonfunction( int(request.GET.get('mytextbox')) )
return render(request,'myApp/templateHTML.html')

#3

How about this:

这个怎么样：

<a class="btn btn-primary" href="{% url 'url-name'%}">Button-Text</a>

The class is including bootstrap styles for primary button.

该类包括主按钮的引导样式。

#4

you can put the input inside a form like this:-

你可以把输入放在这样的表格中： -

<script>
    $(document).ready(function(){
        $(document).on('click','#send', function(){
            $('#hid').val(data)
            document.forms["myForm"].submit();
        })
    })
</script>

<form id="myForm" action="/request_page url/" method="post">
    <input type="hidden" id="hid" name="hid"/>
</form>
<div id="send">Send Data</div>

#5

For eg, a logout button can be written like this:

例如，注销按钮可以这样写：

<button class="btn btn-primary" onclick="location.href={% url 'logout'%}">Logout</button>

Where logout endpoint:

注销终点：

#urls.py:
url(r'^logout/$', auth_views.logout, {'next_page': '/'}, name='logout'),
