dom: $("#ajax_submit")
我必须通过作为第二个参数传递给 validate 方法的对象中的 dom 键 () 的值来指定我想将事件耦合到的元素。
所以我需要的是以下内容:
$('#ajax_validated_form').validate('{% url validate_entity %}', {type: 'ul', dom: $("#ajax_submit"), event: "click"});
编辑:
还要知道,#ajax_validated_form
不一定必须引用一个form
元素才能让验证工作,如果表单输入包含在div
!
例如:
<div id="ajax_validated_form">
{{ ajax_val_form }}
</div>
效果一样好
<form id="ajax_validated_form" action="" method="post">
{{ ajax_val_form }}
</form>

不要忘记在页面脚本中包含以下内容(来自django 文档):
/// To enable Ajax calls with csrf_token protection ///////////////////
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));
}
function sameOrigin(url) {
// test that a given url is a same-origin URL
// url could be relative or scheme relative or absolute
var host = document.location.host; // host + port
var protocol = document.location.protocol;
var sr_origin = '//' + host;
var origin = protocol + sr_origin;
// Allow absolute or scheme relative URLs to same origin
return (url == origin || url.slice(0, origin.length + 1) == origin + '/') ||
(url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + '/') ||
// or any other URL that isn't scheme relative or absolute i.e relative.
!(/^(\/\/|http:|https:).*/.test(url));
}
$.ajaxSetup({
beforeSend: function(xhr, settings) {
if (!csrfSafeMethod(settings.type) && sameOrigin(settings.url)) {
// Send the token to same-origin, relative URLs only.
// Send the token only if the method warrants CSRF protection
// Using the CSRFToken value acquired earlier
xhr.setRequestHeader("X-CSRFToken", csrftoken);
}
}
});
