If i have a form with 3 differents textfields on controller.html, it's possible to send the data of the 3 elements with a "send button" to my screen?
Sending a form would basically work the same as you would do it the usual way in javascript:
Catch the form submission via the onsubmit event
Get the input values and send them via airconsole.message
Something like this:
var form_ele = document.getElementById("form");
form_ele.addEventListener('submit', function(e) {
e.preventDefault();
var input_1_val = your_input_element.value;
airconsole.message(AirConsole.SCREEN, {
input_1: input_1_val,
// other key values
};
});
An AirConsole controller is nothing else than a (mobile) website.

I'm using ajax within the play (scala) framework to run some code after a click event occurs on a page. I want to return the results of that code execution on the same page.
EDIT: the goal of this is to display some rows from the database, along with form elements to fill out to update cells of the databse, all without reloading/or going to a new page
Is there a way to pass html + (scala) values into
Ok(...).as(HTML)
to display without directing to new a page?
I know Ok can take things like:
Ok(<h1>it works</h1>).as(HTML)
but I can't figure out how to combine that with scala values as well. Is there a smarter way to do this?
EDIT: the ajax looks like this:
var ajaxCall = function() {
var ajaxCallBack = {
success : onSuccess,
error : onError
}
jsRoutes.controllers.Application.scrape().ajax(ajaxCallBack);
};
var onSuccess = function(data) {
$("#results").append(data);
}
var onError = function(error) {
alert(error);
}
For sure you can. You can use TWIRL templates:
Create a template "views/Application/contacts.scala.html
#(users: List[User])
<h1>Users</h1>
<ul>
#for(user <- users) {
<li>#user.name</li>
}
</ul>
in the controller:
Ok(views.html.Application.contacts(users))
I have a function which uses following code to fetch form values-
var formValues = this.myForm.getForm().getValues();
MyForm contains a combobox which loads with form. (There are two separate requests for combo load and form load)
As these two requests are loading at the same time, above code do not return combo values as they are still loading.
Is there any way to check whether combo values are loaded and then only send ajax request for form load so that above code will have all form values?
Edited:
LoadComboBox function just fills the data with some store.
Following is the code for form load-
loadFormGrid: function (){
var allValues = this.myForm.getForm().getValues(); // this do not consider combobox values
Ext.Ajax.request({
params: {action: 'getList', data : allValues },
// ... some code
});
}
I would do something like:
On the success event of the combo box load, call the load method of the form/make your ajax request to populate the fields of the form.
EDIT:
Here is what I mean:
The place where you instantiate your ComboBox probably looks like:
var combo = new Ext.form.ComboBox({
store : new someStoreType({
//add to catch the loaded event
listeners : {
'load' : function(store, recs, options){
loadFormGrid();
}
}
})
});
The store listener above ('load') will catch when the combo box is loaded and will call the function to populate/load the form.
I'm using the bassistance validation plugin and have a small script that catches the second submit-button (called preview) and sends the data via ajax to fancybox. I'ld like to validate the forms before they are send to fancybox. At the moment they're only validatet, if I send the forms via the submit-button. I tried in various ways (e.g. I put the call for validation directly after the if and so on) but couldn't get it work. Maybe there's a way to let validate know that it should also react, when the preview-button is hit?
My Code:
$(function() {
$('#myform *').tooltip();
$('#myform ').validate();
});
$(document).ready(function(){
$(':submit').click(function(){
for (var i in CKEDITOR.instances){
CKEDITOR.instances[i].updateElement();
}
var value = $(this).attr("id");
if (value == 'preview') {
$.fancybox.showLoading();
$.ajax({
type : "POST",
cache : false,
url : "../mypath/",
data : $('#myform').serializeArray(),
success : function(data) {
$.fancybox(data, {
'minWidth': '100%',
'minHeight': '100%',
});
}
});
return false;
}
});
});
If i'm not wrong, the Bassistance Validator plugin relies on the fact that if you SUBMIT a form, and the requirements are not met, the function returns a "false" on that submit, enabling you to visually see the errors made.
In your source code, you correctly initialized the Bassistance validator plugin at the very beginning of your code ( I assume you created the rules for it directly on the input fields for example minlength="2" required ) but there is a problem: there is no hook for the SUBMIT event of the submit button, but only for the CLICK event on that button.
There is a simple example on the Bassistance website that shows how you can use custom submit events for the plugin:
http://jquery.bassistance.de/validate/demo/ajaxSubmit-intergration-demo.html
Basically, what you need to do is to insert the intelligent part of your code into
jQuery("#yourform").validate({
submitHandler: function(form) {
jQuery(form).ajaxSubmit({
/*
Here you can do the following:
1) Update the instances of CKEDITOR
2) Check if the submit is in the preview mode
3) If yes
- do your fancy stuff
- return false so that the real submit is not triggered
If not
- return true so that the real submit handler is evaluated by the browser and the POST is triggered
*/
});
}
});
I have a Generic list in my Model class. I want to have a textbox with autocomplete in my view which fills data from the generic list. How can I do this?.
For this you will need
Function on server side which will return list of matching data and will accept string entered by the user.
Something like this
public JsonResult AutoComplete(string input)
{
//Your code goes here
}
In the View, for the text box you need to bind KeyDown event. You can take help of jQuery for this. On key down handler you will make an Ajax call to the function you have defined in the Controller. Some thing like this:
$.ajax({
url: '#Url.Action("AutoComplete", "ControllerName")',
data: 'input=' + sampleInput,
success: function (data) {
//Show the UL drop down
},
error: function (data) {
// Show Error
}
});
In response you will get list of strings, which you will need to bind to some html element like "UI". Once done, display this UI with proper CSS below the text box. Using jQuery, you can retrieve the pixel location of text box too.
You can not use Asp.Net Auto Complete box in your project as you are developing app in MVC (no viewstate). I hope you get the idea.
You can use JQuery Autocomplate.
To fill the list, you can populate the data from you object.
I can't remember the exact Razor syntax, but you can refer to this:
//data is your Model object of type List<String>
var listString = [#foreach(x in data) { '#x',}];
$( "#dataList" ).autocomplete({
source: listString
});
<input id="dataList">
JQuery Autocomplte

This is client side auto complete, I can provide server side if you need.
Here is the problem:
By default jQuery Mobile is using GET requests for all links in the application, so I got this small script to remove it from each link.
$('a').each(function () {
$(this).attr("data-ajax", "false");
});
But I have a pager in which I actually want to use AJAX. The pager link uses HttpPost request for a controller action. So I commented the above jQuery code so that I can actually use AJAX.
The problem is that when I click on the link there are two requests sent out, one is HttpGet - which is the jQuery Mobile AJAX default (which I don't want), and the second one is the HttpPost that I actually want to work. When I have the above jQuery code working, AJAX is turned off completely and it just goes to the URL and reloads the window.
I am using asp.net MVC 3. Thank you
Instead of disabling AJAX-linking, you can hijack clicks on the links and decide whether or not to use $.post():
$(document).delegate('a', 'click', function (event) {
//prevent the default click behavior from occuring
event.preventDefault();
//cache this link and it's href attribute
var $this = $(this),
href = $this.attr('href');
//check to see if this link has the `ajax-post` class
if ($this.hasClass('ajax-post')) {
//split the href attribute by the question mark to get just the query string, then iterate over all the key => value pairs and add them to an object to be added to the `$.post` request
var data = {};
if (href.indexOf('?') > -1) {
var tmp = href.split('?')[1].split('&'),
itmp = [];
for (var i = 0, len = tmp.length; i < len; i++) {
itmp = tmp[i].split('=');
data.[itmp[0]] = itmp[1];
}
}
//send POST request and show loading message
$.mobile.showPageLoadingMsg();
$.post(href, data, function (serverResponse) {
//append the server response to the `body` element (assuming your server-side script is outputting the proper HTML to append to the `body` element)
$('body').append(serverResponse);
//now change to the newly added page and remove the loading message
$.mobile.changePage($('#page-id'));
$.mobile.hidePageLoadingMsg();
});
} else {
$.mobile.changePage(href);
}
});
The above code expects you to add the ajax-post class to any link you want to use the $.post() method.
On a general note, event.preventDefault() is useful to stop any other handling of an event so you can do what you want with the event. If you use event.preventDefault() you must declare event as an argument for the function it's in.
Also .each() isn't necessary in your code:
$('a').attr("data-ajax", "false");
will work just fine.
You can also turn off AJAX-linking globally by binding to the mobileinit event like this:
$(document).bind("mobileinit", function(){
$.mobile.ajaxEnabled = false;
});
