我认为这会解决你的问题：
// ajax components
function getCookie(name) {
var cookieValue = null;
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = jQuery.trim(cookies[i]);
// Does this cookie string begin with the name we want?
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
};
var csrftoken = getCookie('csrftoken');
function csrfSafeMethod(method) {
// these HTTP methods do not require CSRF protection
return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
$.ajaxSetup({
beforeSend: function(xhr, settings) {
if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
xhr.setRequestHeader("X-CSRFToken", csrftoken);
}
}
});
我的表格是什么样子的：
<ul class="sub-menu collapse" id="settings">
<form id="glucose_boundary_form" action="/glucose/goals" method="POST">
{% csrf_token %}
{{ glucose_boundary_form.as_p }}
</form>
<button type="submit" id="glucose_goals">Submit</button>
</ul>
按钮点击是什么样子的
$('button#glucose_submit').click(function() {
$.ajax({
url:'glucose/submit',
type: 'POST',
data: $('form#glucose_form').serialize(),
success: function(data) {
document.getElementById("glucose_form").reset();
}
});
});
编辑：
这是我的登录和注册视图。虽然我不使用ajax进行注册。登录页面会自动进行表单验证。希望他们能帮助您了解我在做什么以及如何应用我的答案。
