我正在尝试对我的 (Django) 表单中的电子邮件字段实现远程验证，但收到错误“无法读取未定义的属性“addAsyncValidator””。
模板(我使用 last dist of Parsley ，因此不需要 remote.parsley.js)
<head>
<script src="{% static 'js/parsley.js' %}"></script>
</head>
<form id="user_form" method="post" action="/register/" enctype="multipart/form-data">
{% csrf_token %}
<input data-parsley-remote="/check_email/"
data-parsley-remote-message="The introduced email has already been registered!"
data-parsley-remote-options="{ 'type': 'POST' }"
data-parsley-remote-validator="emailAvailable"
data-parsley-remote-reverse="false"
data-parsley-required="true"
data-parsley-required-message="This field is required."
data-parsley-trigger="change"
data-parsley-type="email"
id="id_email"
name="email"
required="required"
type="email"
value="a@a.com"/>
{{ user_form.as_p }}
<input type="submit" class="btn btn-info submit" name="submit" value="Register" />
</form>
脚本
var csrftoken = $.cookie('csrftoken');
function csrfSafeMethod(method) {
// these HTTP methods do not require CSRF protection
return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
$.ajaxSetup({
beforeSend: function(xhr, settings) {
if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
xhr.setRequestHeader("X-CSRFToken", csrftoken);
}
}
});
$(function() {
$("#user_form").parsley();
});
$('[name="email"]').Parsley.addAsyncValidator('emailAvailable', function (xhr) {
var emailExists = this.$element.val().startsWith(xhr.responseJSON.email + "@");
return !emailExists;
}, '/check_email/');
我错过了什么？
最佳答案
Parsley是一个全局变量。您需要调用Parsley.addAsyncValidator(...)设置自定义函数来分析 ajax 调用的结果，但不 $somejQueryobject.Parsley.whatever .
关于javascript - 使用 Parsley.js 进行远程验证，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35775158/
