我的ajax脚本有点问题，当你自己在下拉列表中选择值时脚本运行正常。但是当你点击提交时，它会获取值并将其置于GET中。
当你转到“http://script.domain?prov=1”（它在下拉列表中触发选定的值）时，ajax脚本无效（我认为是因为。（更改），当它的值被预先选中时它没有改变所以脚本没有反应。）
所以我需要脚本在加载页面时自动运行并检查#prov dropbox值。
这是链接https://jsfiddle.net/gfzd5aa1/1/
HTML
<form action="" method="get">
<label for="prov">Provincia: </label>
<select name="prov" id="prov" class="form-control">
<option value="0">Selecciona la provincia</option>
{% for provincia in provincias %}
<option value="{{ provincia.id }}" {% if get.prov == provincia.id %} selected {% endif %} > {{ provincia.name }} </option>
{% endfor %}
</select>
<label for="zona">Provincia: </label>
<select name="zona" id="zona" class="form-control">
</select>
</form>
“Provincia”选择字段触发ajax填充“Zona”选择。
$('#prov').on('change', function() {
var self = $(this);
$.ajax({
url: 'http://localhost:8888/casas/public/ajax-prov',
type: 'GET',
data: { id: self.val() },
dataType: 'json',
success: function(response){
var $zona = $("#zona");
$zona.empty(); // remove old options
$("#zona").append('<option value="0">Seleciona la Zona</option>');
$.each(response.prov, function(i, state) {
$("#zona").append('<option value="'+ state.id +'">' + state.name + '</option>');
});
}
});
});
我的javascript技能非常基础，如果你可以帮助我让它工作，我会很感激。

您没有向获取请求发送class AccountViewController: FormViewController {
let Client = Client()
var users: [User]?
var name: String?
var email: String?
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override func viewDidLoad() {
super.viewDidLoad()
Client.Service.getId() { users, error in
if users != nil {
self.users = users
if self.users?.count != 0
{
self.loadForm()
self.name = self.users![0].name// IS NOT NIL
self.email = self.users![0].email// IS NOT NIL
}
} else {
print("error: \(error)")
}
}
}
private func loadForm() {
let form = FormDescriptor()
form.title = "Example Form"
let section1 = FormSectionDescriptor()

form.sections = [section1, section2, section3, section4]
self.form = form
}
}
变量，而是发送prov。
试试这个：
id编辑： 小姐理解了这个问题所以最后的回答是
...
$.ajax({
url: 'http://localhost:8888/casas/public/ajax-prov',
type: 'GET',
data: { prov: self.val() },
...
