I've been looking at the documentation and tutorials for Sencha Architect, and I can't figure it out. What I want to is have a button press post a value to a PHP script on a server, and then retrieve the result from a PHP session variable. From what I've seen, I'm not sure if I can get it to call PHP at all, much less read a session variable.
I realize there may be a few questions in here (connecting the button to a controller/store, calling the script, reading the result), but I don't know enough about Architect to know if they're the correct ones.
EDIT: I think I've got the button connected to a controller, but I'm still not sure how to get it to call the PHP script.
EDIT 2:
I added a BasicFunction to the button, but I can't get it to work. Here's the code:
// Look up the items stack and get a reference to the first form it finds
var form = this.up('formpanel');
var values = form.getValues().getValues()[0];
Ext.Msg.alert('Working', 'Loading...', Ext.emptyfn);
Ext.Ajax.request({
url: 'http://wereani.ml/shorten-app.php',
method: 'POST',
params: {
url: values
},
success: function(response) {
Ext.Msg.alert('Link Shortened', Ext.JSON.decode(response).toString(), function() {
form.reset();
});
},
failure: function(response) {
Ext.Msg.alert('Error', Ext.JSON.decode(response).toString(), function() {
form.reset();
});
}
});
Also, is that the correct way to get the value from the field (itemID:url)? I couldn't find anything in the documentation for Touch about that.
Use an Ext.Ajax request in the listener for the button. docs.sencha.com/touch/2.2.1/?mobile=/api/Ext.Ajax.
The documentation there is pretty straightforward. If you have trouble please post some specifics and I'll try to write you an example.
Good luck, Brad

I'm new in coding and currently creating a website that supports English and Russian languages. I want to change between them with no page reload, so I decided to use AJAX to achieve it and store information in JSON. I have a checkbox that changing my langString between EN and RU depending on checkbox state.
var langStr = "en";
$('#langsw').click(function(){
if($(this).prop("checked") == true){
console.log("Checkbox is checked.");
langStr = "ru";
}
else if($(this).prop("checked") == false){
console.log("Checkbox is unchecked.");
langStr = "en";
}
});
And this is jquery code to perform AJAX part
$.ajax({
type:'GET',
dataType:'json',
url: langStr+".json",
cache:true,
success: function(data){
$('#meet').append(data.title);
$('#meet').append(data.hr);
$('#meet').append(data.subtitle);
},
error: function(data){
console.log("there is an error")
}
});
My JSON is
{
"title":"<h1 style=\"color:white; font-size: 42pt\">Name</h1>",
"hr":"<hr style=\"width:60%\">",
"subtitle":"<h1 style=\"color:#dbdbdb; font-weight:100\">Interactive resume</h1>"
}
and the second one is the same in Russian.
Now the question: I want to cache both JSONs and then use one of them depending on the state of the checkbox, but I don't know how to do so. If you have any ideas relating to other ways of achieving this I will be very happy to read them.
P.s English is my 2 language so forgive the mistakes.
You can save the information in localstorage (altough there is a limit of how much you can save there).
You can use this formula to save raw json into localstorage
localStorage.setItem('language-ru', data);
To get what is in localstorage you would use
const ru = localstorage.getItem('language-ru')
So you can check, if user has the right language in his localstorage and if there is nothing, you can download it with that ajax call.
You can read more about localstorage here: https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage
I am building several apps and want to be able to reuse som code as separate HTML pages by passing parameters to them.
I would really like to pass parameters via ajax with one of these:
Alt1
$.mobile.pageContainer.pagecontainer("change", "../Photo/Photo.html", { reload: true, parameter: "dummyParameter"});
$.mobile.changePage("../Photo/Photo.html", { reloadPage: true, parameter: "dummyParameter"});
Problem is that the page wont reload.
If I use the below link the page is loaded/reloaded, but I cant seem to find the passed parameter.
Alt2
Or through a basic link
(I would prefeer to not generate the url in javascript as in alt2 but if what it takes...)
I use this code to try to retreive the parameters:
$(document).on("pagebeforechange", function (e, data) {
if (data.toPage[0].id == "Photo") {
//var parameters = $(this).data("url").split("?")[1];
//var parameter = parameters.replace("paremeter=", "");
var stuff = data.options.stuff;
//showStuff("#p2", stuff);
}
});
While I'm at it, if someone uses type script. Visual studio complains about that this call signature isnt correct:
$(document).on("pagebeforechange", function (e, data)
Expects one argument, the event, not the data. The plugin generates correct javascript but the IDE complains.
Thanks!
I know hat it is possible, but I am not quite sure how to do it the 'right' way, as to ensure there are no conflicts.
I came across this question: Cannot call functions to content scripts by clicking on image . But it is so convoluted with random comments that it's hard to understand what the corrected way was.
Use case:
Html pages have a div on the page where they expect anyone using the Chrome extension to inject a picture. When users click on he picture, I want to somehow notify an event script. So I know I need to register a listener so the code inserted messages the event script.
Can I get some indication on what code to inject through the content script? I saw that sometimes injecting jquery directly is advised.
I am trying to avoid having the html page to post a message to itself so it can be intercepted. Thanks
With the help of Jquery something like this would capture the image onclick event and allow you to pass a message to a background page in the Chrome Extension:
$("img").click(function(){
var imageSrc = $(this).attr("src");
//Post to a background page in the Chrome Extension
chrome.extension.sendMessage({ cmd: "postImage", data: { imgSrc: imageSrc } }, function (response) {
return response;
});
});
Then in your background.js create a listener for the message:
chrome.extension.onMessage.addListener(
function (request, sender, sendResponse) {
if (request.cmd == "postImage") {
var imageSrc = request.data.imgSrc;
}
});
I am having difficulty replacing the content of an HTML element with a JSON object property. Here's my code:
url = '/blah/blah-blah';
data = $.getJSON(url);
$(this).parent('.status').replaceWith(data.content);
Now, I know that the correct JSON object is being returned and that it includes a properly formatted property called 'content'. (I am displaying it in the console). Secondly, I know that I am selecting the correct element to replace. (If I replace data.content with 'bingo!' I see the text displayed on screen.)
When I run the code above, however, I see the content of my element replaced with nothing. What am I doing wrong?
Note that I tried replacing data.content with data.responseJSON.content, but that didn't help.
Thanks!
You need to use a callback,
url = '/blah/blah-blah';
$.getJSON(url, function(data) {
$("some selector").parent('.status').replaceWith(data.content);
})
In your example, $.getJSON doesn't return anything meaningful -- probably just 'undefined'. Meanwhile, it makes your request. When getJSON succeeds, the result is passed to a handling function which does things with it. If you don't provide a callback, nothing will happen when you get a response back from the server.
or if you don't want to use a new selector, you can save $(this).
url = '/blah/blah-blah';
item = $(this)
$.getJSON(url, function(data) {
item.parent('.status').replaceWith(data.content);
})
The AJAX call is asynchronous, so the content hasn't arrived yet when you try to use it. When you display it in the console, you can't do that fast enough to see that the response doesn't arrive immediately.
Use a callback in the getJSON call to handle the data when it arrives:
url = '/blah/blah-blah';
$.getJSON(url, function(data) {
$(this).parent('.status').replaceWith(data.content);
});
Your code is executing before the .getJSON(url) call is completing. Try specifying a success handler like so:
$.getJSON(url, function(data) {
$(this).parent('.status').replaceWith(data.content);
});
I have searched many times and find examples which match my code structure perfect. Yet I am not getting the results from my ajax to display on the input box.
I get results from the POST that have been evaulated with firebug and everything looks great.
Here is the javascript im using.
<script type="text/javascript" language="javascript">
$(function () {
$("input.FamousPerson-List").autocomplete({
source: function (request, response) {
$.ajax({
url: "/FamousPeople/FPPAutoComplete",
type: "POST",
dataType: "json",
data: {
searchText: request.term,
maxResults: 12
},
success: function (data) {
response($.map(data, function (item) {
return {
value: item.DisplayName
}
}))
}
});
}
});
});
Here is a link of the actual code I am using on the web.AutoCompleteTesting Type just about any letter in one of the boxes below to invoke it.
Thanks.
If you look closely at the request being sent up, you'll notice that a callback parameter is being added. Weird, right? Since you're doing a local AJAX post, not a cross-domain (JSONP) one.
I noticed that your project includes jQuery Validate. According to this answer to a question dealing with a similar problem (performing a JSONP request instead of a normal JSON request even though you asked for one), it's a known issue in jQuery validate.
Judging by the other answer, you can change your version of jQuery or perhaps use a patched version of jQuery validate (found here).
