我是AJAX編程新手，並且正在使用AJAX應用程序。AJAX無法在CodeIgniter表單提交中執行
我使用PHP與CodeIgniter框架，我想創建表單時提交，它會返回一個成功的消息，無需重新加載頁面，這就是爲什麼我選擇了Ajax。但從我所做的代碼，它沒有閱讀的AJAX工作，它移動到另一個頁面，當然，沒有成功的消息顯示
所以我的主要問題是我的AJAX表單提交無法執行和我不明白爲什麼。
任何幫助，將不勝感激。
這裏是我的Controller.php這樣
public function index()
{
$this->form_validation->set_rules('advice', 'Advice', 'required');
$data["CatId"]=$this->viewbook_model->getCategory();
$this->ckeditor->basePath = base_url().'assets/ckeditor/';
$this->ckeditor->config['toolbar'] = array(
array('Source', '-', 'Bold', 'Italic', 'Underline', '-','Cut','Copy','Paste','PasteText','PasteFromWord','-','Undo','Redo','-','NumberedList','BulletedList')
);
$this->ckeditor->config['language'] = 'it';
$this->ckeditor->config['width'] = '730px';
$this->ckeditor->config['height'] = '300px';
//Add Ckfinder to Ckeditor
$this->ckfinder->SetupCKEditor($this->ckeditor,'../../assets/ckfinder/');
if($this->session->userdata('is_logged_in')){
$this->load->model('feedback_model');
$data['feedback'] = $this->feedback_model->get_subject();
$advice_list = $this->feedback_model->get_subject();
$x = 0;
foreach($advice_list AS $al)
{
$data['feedback'][$x] = array(
'CategoryAdviceId' => $al['CategoryAdviceId'],
'CategoryAdviceName' => $al['CategoryAdviceName']
);
$x++;
}
$data['booklist'] = $this->feedback_model->find($this->session->userdata('username'));
$book_list = $this->feedback_model->find('username');
$y = 0;
foreach($book_list AS $bl)
{
$data['booklist'][$y] = array(
'AssetTitle' => $bl['AssetTitle'],
'bi' => $bl['bi']
);
$y++;
}
$data['adviceid'] = $this->feedback_model->get_adviceId();
$adviceid_list = $this->feedback_model->get_adviceId();
$x = 0;
foreach($adviceid_list AS $adv)
{
$data['adviceid'][$x] = array(
'AdviceId' => $adv['AdviceId']
);
$x++;
}
$page_content["page_title"] = "Send Feedback";
$page_content["title"] = "Suggestion and Feedback";
$page_content["icon_title"] = "home";
$menu_params["current_navigable"] = "Feedback";
$menu_params["sub_current_navigable"] = "";
$page_content["menu"] = $this->load->view("main_menu", $menu_params, true);
$page_content["content"] = $this->load->view("feedback", $data, true);
$page_content["navmenu"] = $this->load->view("nav_menu", $data, true);
$this->load->view("template/main_template", $page_content);
}else{
redirect('login/restricted');
}
}
//this is the function that sent data to model and return json to view for display success message
function insert_to_db()
{
$this->feedback_model->insert_into_db();
echo json_encode('true');
}
這是view.php

我的表單代碼，這是我的腳本和AJAX代碼：
$(document).ready(function() {
//this is for CKEDITOR validation
for(var name in CKEDITOR.instances) {
CKEDITOR.instances["Advice"].on("instanceReady", function() {
// Set keyup event
this.document.on("keyup", updateValue);
// Set paste event
this.document.on("paste", updateValue);
});
function updateValue() {
CKEDITOR.instances["Advice"].updateElement();
$('textarea').trigger('keyup');
}
}
//this is my form validation
$("#feedback_form").validate({
ignore: 'input:hidden:not(input:hidden.required)',
rules: {
CategoryAdviceSelect:"required",
Subject:"required",
Advice:"required",
BookSelect:{
required: function(element){
return $("#CategoryAdviceSelect").val()==1;
}
}
},
messages: {
CategoryAdviceSelect:"Please select one of category advice",
Subject:"This field is required",
Advice:"This field is required",
BookSelect:"This field is required",
},
errorElement: "span",
errorPlacement: function (error, element) {
if ($(element).attr('name') == 'Advice') {
$('#cke_Advice').after(error);
} else {
element.after(error);
}
},
highlight: function(element) {
$(element).parent().addClass("help-block");
},
unhighlight: function(element) {
$(element).parent().removeClass("help-block");
}
});
//this is my ajax submission
$("#btnSubmit").click(function() {
var formURL = $(this).attr("action");
var methodtype = $(this).attr("method");
$.ajax({
url : formURL,
type: methodtype,
data : {
CategoryAdviceSelect:CategoryAdviceSelect,
Subject:Subject,
Advice:Advice,
BookSelect:BookSelect,
TypeAdviceId:TypeAdviceId,
NoBook:NoBook
},
ajaxOptions: {
dataType: 'json'
},
success : function(data){
setTimeout(function() {location.reload(true)}, 1700);
$('#success .success-content span').html('Thankyou for your <b>feedback</b>');
$('#success').fadeIn();
setTimeout(fade_out, 1200);
}
});
return false;
});
});
'反饋/反饋/ insert_to_db'是這個正確的URL –
我想是這樣，因爲它的工作正常，沒有AJAX與該網址@ Nouphal.M – RainBi
你檢查了任何js錯誤。使用螢火蟲 –
