I am using jQuery-ui autocomplete to create a search field with a remote data source. Everything works and I get results, however the results does not display in a list below the textfield like it is supposed to. The results are put in a list and gets displayed at the bottom of the page.
Here is my code:
<script>
$(function() {
$( "#autocomplete" ).autocomplete({
source: function(request,response)
{
$.ajax({
url: "<?php echo $this->webroot; ? >portfolios/ajax_clients_dropdown/"+request.term+".json?callback=ajax_clients_dropdown?",
// dataType: "text",
async: false,
//jsonp: "callback",
jsonpCallback: "ajax_clients_dropdown",
success: function(data)
{
var fin = [];
for(a=0;a<10;a++)
{
fin[a]= data[a].value;
}
console.log(fin);
response(fin);
console.log("success");
},
appendTo: "#autocomplete",
position: {'my': 'left top', 'at': 'left top', 'of': '#autocomplete'},
error: function(response){console.log("Fail");}
});
}
});
});
</script>
<div class = "ui-widget" id="container">
<label for ="autocomplete">Clients</label>
<input id = "autocomplete" style ="" autocomplete = "on">
</div>
It doesn't matter weather I do the appendTo with #container or #autocomplete, it does nothing.
Here is the result that's supposed to be displayed:
["3434a62c bf592581", "a3ee7766 7894a7e0", "ea41d8ec 4e7df334", "919f6fac 96d4cdf0", "24ecac17 bfbed443", "f0270fc4 a2659300", "ea803fac 94b43df4", "5337467f 1a41e158", "fc54b844 0a19b69e", "a7393c7b aaea998b"]
Does anyone have an idea why this is happening?
I think that there might be a few issues here. If you just want the default behaviour for displaying, then you shouldn't need to mess with appendTo or position. Try the following:
<script>
$(function() {
$( "#autocomplete" ).autocomplete({
source: function(request,response) {
$.ajax({
url: "<?php echo $this->webroot; ?>portfolios/ajax_clients_dropdown/"+request.term+".json?callback=ajax_clients_dropdown?",
// dataType: "text",
async: false,
//jsonp: "callback",
jsonpCallback: "ajax_clients_dropdown",
success: function(data) {
var fin = [];
for(a=0;a<10;a++)
{
fin[a]= data[a].value;
}
console.log(fin);
response(fin);
console.log("success");
},
error: function(response){console.log("Fail");}
});
}
});
});
</script>
<div class="ui-widget" id="container">
<label for="autocomplete">Clients</label>
<input id="autocomplete" style="" autocomplete="on">
</div>
Except for the data source, which you say is working, this should be the same as what I have here.
Edit: This answer doesn't fix the problem, see comments for details.
Your appendTo and position properties have been assigned to the AJAX request, not to the autocomplete call. It's easier to see with the indentation fixed.
$(function() {
$( "#autocomplete" ).autocomplete({
source: function(request,response) {
$.ajax({
url: "<?php echo $this->webroot; ?>portfolios/ajax_clients_dropdown/"+request.term+".json?callback=ajax_clients_dropdown?",
// dataType: "text",
async: false,
//jsonp: "callback",
jsonpCallback: "ajax_clients_dropdown",
success: function(data) {
var fin = [];
for(a=0;a<10;a++)
{
fin[a]= data[a].value;
}
console.log(fin);
response(fin);
console.log("success");
},
error: function(response){console.log("Fail");}
});
},
appendTo: "#autocomplete",
position: {'my': 'left top', 'at': 'left top', 'of': '#autocomplete'}
});
});
For those of you who have this issue, first make sure you go here:
https://jqueryui.com/autocomplete/
And you are referencing the correct css and jquery files. Next, this was my issue in ASP.NET MVC 4. I created a bundle, using
bundles.Add(new StyleBundle("~/Content/themes/base/css").Include(
"~/Content/themes/base/core.css", .....
but when I referenced it in my layout page, instead of calling #Styles.Render("~/Content/themes/base/css") I was calling #Scripts.Render("~/Content/themes/base/css").
This caused
<script src="/Content/themes/base/jquery-ui.css"></script>
to be inserted rather than
<link href="/Content/themes/base/jquery-ui.css" rel="stylesheet"/>
so for those of you running into this situation using MVC, that could be it, or you may just not be referencing the correct css and js files properly.

I'm using the following code to receive some content from a page called filter.PHP. But the issue is the buttons become not clickable once fetched.
<script type="text/javascript">
$(document).ready(function() {
$("#display").click(function() {
$.ajax({
type: "POST",
url: "filter.php",
dataType: "html",
success: function(response) {
$("#responsecontainer").html(response);
}
});
});
});
</script>
I have buttons like these on the filter.php file.
<button onclick="location.href='details.php?id=<?php echo htmlspecialchars($result->nid); ?>'" class="buttonnew">Details </button>
Any help would be much appreciated.
You have to add the event listener from JavaScript, when you fetch the html from an ajax response.
document.querySelector('.buttonnew').addEventListener('click', () => { location.href=''});
Or
document.querySelectorAll('.buttonnew').forEach(btn => { btn.addEventListener('click', () => { location.href='';})});
Form submit is not happened in this scenario..
$.ajax({
type: "POST",
async: false,
url: base_url+"register/registration_val",
data: "register_first_name="+first_name,
success: function(data){
$('#inferiz').html(data);
},
error: function(){
alert('error');
}
In your view you can add this:
<script type="text/javascript">
var base_url = "<?php print base_url(); ?>";
</script>
Plus try to alert and see the value of final url in ajax i.e alert(url);
Try adding a id to the firstname input
<script type="text/javascript">
$(document).on('submit','#form-reg',function(){ // #form-reg is id on form open tag
$.ajax({
url: "<?php echo base_url('register/registration_val');?>",
type: 'POST',
data: {
firstname: $('#firstname').val(),
},
dataType: 'html', // I perfer to use json
success: function(data){
$('#inferiz').html(data);
},
error: function(){
alert('error');
}
}
});
});
</script>
I would use dataType: json much easier that way to get data from controller
You used data: "register_first_name="+first_name, it's not correct. Correction is data: {register_first_name:first_name},
base_url like this var base_url = <?php echo base_url(); ?>
So, Bellow final code :
<script type="text/javascript">
jQuery(document).ready(function ($) {
var base_url = <?php echo base_url(); ?>
$.ajax({
url: base_url+"register/registration_val", // Url to which the request is send
type: "POST", // Type of request to be send, called as method
data: {register_first_name:first_name}, // Data sent to server, a set of key/value pairs representing form fields and values
contentType: false, // The content type used when sending data to the server. Default is: "application/x-www-form-urlencoded"
}).done(function (data) {
$('#inferiz').html(data);
}).fail(function (data) {
console.log('failed');
});
}(jQuery));
</script>
Please verify your view part that whether you provided id same as in ajax function.
view part:
<form id="form-reg">
<input name="firstname" id="firstname" type="text" required placeholder="Enter firstname " >
<span id="name_validation" class="text-danger"></span>
<button name="submit" id="submit_button" onClick="myFunction();" >submit</button>
</form>
Then correct the base url path which has to be given inside php tag.
function myFunction() {
$.ajax({
url: "<?php echo base_url();?>register/registration_val",
type: "POST",
data:'firstname='+$("#firstname").val(),
success: function(msg)
{
alert('done..!');
}
});
}
<div data-role="main" class="ui-content">
<ul data-role="listview" id="responsecontainer" >
</ul>
This is my html file.
var output = $('#responsecontainer');
$.ajax({
url: 'http://192.168.1.28/mobile/db_select.php',
dataType: 'jsonp',
jsonp: 'jsoncallback',
timeout: 5000,
success: function(data, status){
$.each(data, function(i,item){
var landmark = '<li><a href="#"><h2>'+item.tr_issue+'</h2>'
+ '<p>'+item.tr_assign+'</p></a></li>';
output.html(landmark);
console.log(output);
});
},
error: function(){
output.text('There was an error loading the data.');
}
});
This is my JavaScript.
I want to populate my listview from my database(mysql) but the problem is when it generates the theme of jquery mobile di not work.
its like a simple unordered list. thanks in advance
Add $('ul').listview('refresh'); after appending the HTML
Show change your success callback as below
success: function(data, status){
$.each(data, function(i,item){
var landmark = '<li><a href="#"><h2>'+item.tr_issue+'</h2>'
+ '<p>'+item.tr_assign+'</p></a></li>';
output.html(landmark);
console.log(output);
});
$('ul').listview('refresh');
},
i have a script handlebar..
<script id="ownerItem" data-template-name='ownerItem' type="text/x-handlebars">
{{value.UserName}} <button {{action "remove" on="click"}}>Remove</button>
</script>
And its view..
ResAdmin.ownerView = Ember.View.extend({
templateName: 'ownerItem',
remove: function() {
var selectedRest;
selectedRest = ResAdmin.adminController.get('selectedRestaurant');
alert(value.RestaurantOwnerID);
return $.ajax({
url: '/api/RestaurantOwner/' + value.RestaurantOwnerID,
cache: false,
type: 'delete',
data: {
RestaurantID: selectedRest.RestaurantID,
MethodOverride: 'delete'
},
dataType: 'jsonp',
success: function(data) {
return ResAdmin.adminController.getRestaurantList();
}
});
}
});
and in some other view i am using this view like
{{#each ResAdmin.adminController.selectedRestaurant.Owners}}
{{view ResAdmin.ownerView valueBinding="this" content="this"}}
{{/each}}
but i am getting error(value is not defined) when user click on remove button of my nested view...can anybody help me ??
value is a property of the ownerView so you need to qualify it with this.get('value')
e.g.
this.get('value').RestaurantOwnerId

controller.php -simple php file that return json array:
<?php
$arr=array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
echo json_encode($arr);
?>
Thanks
The form has a default action with a type="submit" button, which is submitting, so you'll need to stop that from happening by adding return false or event.preventDefault() , like this:
$(document).ready(function() {
$('#submit-html').click(function(e) {
$.ajax({
url: 'controller.php',
type: 'POST',
dataType:'json',
success: function(data) {
alert("response begin");
alert(data);
$.each(data, function (i, elem) {
$('#array-values').append('<div>'+elem+'</div>');
});
}
});
return false;
//or e.preventDefault();
});
});
Without this, the form is submitting as it normally would with no JavaScript, leaving the page. So effectively it's doing a refresh, instead of AJAX submitting your form (which doesn't have time to complete...because you left :)
An element of type=submit inside a <form> will perform the form request when clicked on.
You need to abort the default behavior by running event.preventDefault() inside the click callback.
My guess is that the form is submitting and refreshing the page before the ajax has a chance to respond.
Try putting return false; at the end of the click handler.
$('#submit-html').click(function() {
$.ajax({
url: 'controller.php',
type: 'POST',
dataType: 'json',
success: function(data) {
alert("response begin");
alert(data);
$.each(data, function(i, elem) {
$('#array-values').append('<div>' + elem + '</div>');
});
}
});
return false;
});
Of course you'll have the same issue if the user hits Enter in one of the fields. Unless you're preventing the Enter key from submitting the form, you may want to the handle the event using the submit() handler.
$('#parse-form').submit(function() {
$.ajax({
url: 'controller.php',
type: 'POST',
dataType: 'json',
success: function(data) {
alert("response begin");
alert(data);
$.each(data, function(i, elem) {
$('#array-values').append('<div>' + elem + '</div>');
});
}
});
return false;
});
Try using submit() http://api.jquery.com/submit/ , this should work with keyboard events as well as clicks. You can use serialize() to get any form data into the ajax objects data variable.
