I have a page that gets content from other file through ajax, it works perfect, but when navigated through address bar, it s not working as the event is triggered only on click. I ve searched, but i couldnt find a solution that fits my need. I ve given my code. Somebody help.
Profile
<div id="home-content" class="container-fluid"></div>
<script>
function profile(){
$.ajax({
type: "POST",
url: "functions.php",
data: {action:profile},
success: function(response)
{
$('#home-content').html(response);
}
});
}
</script>
All i want is when i enter address like home/#profile , profile page has to be loaded and it also should be navigatable, with history entry for 'profile' page
Please Use this function
<body onload="profile()">
and remove in Onclick funtion

I am stuck in this like I have never before.
My situation : I am making a shopping cart. When user click "Add" button, it posts the form and in the server side i.e inside if(IsPost){....}, corresponding item gets added to the the the cart table in my database.
Everything is fine, except it reloads the page and scrolls back to top. With a little research, I got to know that may be Ajax could help. Then I created a new .cshtml page add-to-cart.cshtnl. Now my current page doesn't reload but it opens add-to-cart.cshtml which is not how I wanted. Now I even tried to learn AJAX and try doing things looking at examples. Nothing helps. Please help!
Here is what my code looks like : P.S I am using razor in webmatrix.
<form method="post" id="productForm" action="~/add-to-cart.cshtml">
<input ............"Input Something.............../>
<button type="submit" id="add-button" >ADD</button>
</form>
At my add-to-cart.cshtml, I don't have anything on the UI. It just processes data.I don't want that page to ever load. It looks something like this:
ifIsPost(){
............ADD item to the cart table of database..............
}
Now I am convinced, AJAX is my solution but how????
Please don't give me incomplete answers. I have already wasted 3 days in it :/
Try this
$('#productForm').submit(function(e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: $(this).attr('action'),
data : $(this).serialize(),
success : function(response) {
//write your code here
},
error : fucntion(response) {
//write your code here
}
});
});
Put this script into <script> tag.
Note: Don't forgot to include jquery in your page.
Here is the complete working solution :
$(function () {
$('#productForm').submit(function (ev) {
var frm = $(this);
$.ajax({
type: frm.attr('method'),
url: frm.attr('action'),
data: frm.serialize(),
success: function (data) {
//Do What Ever You Wanna Do
}
});
ev.preventDefault();
});
});
Is it possible to simply run the knp paginator with ajax? Is it possible at all and what is the best way to do it ?
Greetings Michael
Not sure if this is best solution, but I did it this way:
$(function(){ $('#dish-select-component-canvas').on('click', "ul.pagination a" , function(e){
$.ajax({
type: "GET",
url: $(this).attr('href'),
})
.done(function( msg ) {
$('#dish-select-component-items').html(msg);
});
e.preventDefault();
});
});
#dish-select-component-canvas is container for page. When somebody click on this canvas on link in ul.pagination (pagination is class used by knpPaginator by default as wrapper for pagination), I take href attribute of that link, and send it with ajax GET request.
Result of that request goes to appropriate div (here to #dish-select-component-items). Of course you must remember to add e.preventDefault() to prevent browser from reloading the page.
I am trying to display different forms based on user type using Ajax post request. The request response works fine but I don't know how to display the form. For example, if the user selects parent then I want the parent form to be displayed and so on. I'm using ZF 1.12.
public function init() {
$contextSwitch = $this->_helper->getHelper('AjaxContext');
$contextSwitch =$this->_helper->contextSwitch();
$contextSwitch->addActionContext('index', 'json')
->setAutoJsonSerialization(false)
->initContext();
}
public function indexAction() {
$this->view->user = $this->_userModel->loadUser($userId);
//if($this->_request->isXmlHttpRequest()) {
//$this->_helper->layout->disableLayout();
//$this->_helper->viewRenderer->setNoRender(true);
if ($this->getRequest()->isPost()){
$type = $_POST['type'];
$this->view->userForm = $this->getUserForm($type)->populate(
$this->view->user
);
}
}
And here's what I have on the client side. What do I need to write in the success section?
<script type="text/javascript">
$(document).ready(function(){
$('#userType').on('change', function(){
var type = $(this).val();
select(type);
});
});
function select(type) {
$.ajax({
type: "POST",
url: "admin/index/",
//Context: document.body,
data: {'type':type},
data: 'format=json',
//dataType: "html",
success: function(data){
// what to do here?
},
error: function(XMLHttpRequest, textStatus, errorThrown) {}
});
}
</script>
<form id="type" name="type" method="post" action="admin/index">
<select name='userType' id='userType' size='30'>
<option>admin</option>
<option>parent</option>
<option>teacher</option>
</select>
</form>
<div id="show">
<?php //echo $this->userForm;?>
</div>
If your ajax request form returns you the HTML from the Zend_Form, you could simply write the HTML in the #show div.
In you view you will need to do this :
echo $this->userForm;
This way, all the required HTML will be written on the server side, before sending the response to the HTML page. In the HTML page you then just have to write the response in the right location with the method $('#show').html(data). You also have to make sure that each of your forms has the right action when you render them.
The other option would be to have all three forms hidden in your page (through Javascript) upon loading and based on the select (Generated with JS), display the right form. This way you don't have to load data from an external source and if someone have JS disabled, he still can use the application. On the other hand, this method will have each page load about 1/2 a KB more of data.
Below is the code snippet which is hitting the url on server and getting the html response.I can see
the response inside firefox debugger but it does not display in div tag.
$.ajax({
url: url,
dataType: 'html',
data: '',
type: 'POST',
success: function(data) {
//in firefox debugger i can see complete html response inside data
$('#displayContent').html(data); // but here, it does not
// append the html inside div displayContent. Instead it makes
// the current page blank
}
});
I don't get what mistake I'm making here Can I not directly assign the ajax html response to an selector(div tag in my case) with $('#displayContent').html(data)?
Instead of using html() method use append i.e.
$('#displayContent').append(data);
Or if you want to assign whole content direct to your element use load method
$(function(){
$('#displayContent').load(url);
});
If you've got a form tag on your page, and you're trying to submit it asynchronously with jQuery, your function will need to return false, to prevent the browser from handling the form.
Example:
$("form").submit(function () {
$.ajax(...);
return false;
});
So here is my HTML:
<div class='delete-item' name='filetest' ></div>
<div class='delete-item' name='anothertest' ></div>
<div class='delete-item' name='coolfile' ></div>
And my JavaScript
$(".delete-item").click(function() {
$.ajax({
type: "GET",
url: "delete_item.php",
data: "name="+$(this).attr("name")+"&dir=<?php echo $encodedDirectory; ?>",
success: function(data) {
refreshItemList();
}
});
});
So the code works but only for one item. Whichever one I click first works and the ajax call is completed succesfully. However clicking on another does not even call the function (I tried by logging it to the console and it wasn't even logging anything except for the first item.)
Try using jQuery.live instead of bind:
$(".delete-item").live('click', function() {
When you do $(".delete-item").click(...) jquery attaches an event to all .delete-item elements on the page. But in refreshItemList(); you replace them with new ones, and no event handler is attached to the new ones.
jQuery.live() attaches events on all elements matching .delete-item at the time you call it, and also .delete-item created after you call it.
