how do we pass an object on $.mobile.changePage and access it on "pagebeforeshow" ???
I am using JQM 1.3.1 and jquery 1.9.1
$.mobile.changePage("Next.html", {data: RespObj});
$(document).on("pagebeforeshow","#next", function(data)
{
alert(JSON.stringify(data));
});
can anyone please help me figure this out. I am not able to access this data inside pagebefore show.
As per I saw, I think you did some syntax mistake with the pagebeforeshow part.
Change your code to the following one and check, hope it will work:
Try this one
$.mobile.changePage("Next.html#next", {data: RespObj});
$(document).on("pagebeforeshow",function(data)
{
alert(JSON.stringify(data));
});
If it works don't forget to VOTE
Thank you and all the best

From the index page, a user clicks a navigation link, the data attribute is passed via ajax, the data is retrieved from the server but the content is not being updated on the new page.
Been stuck for hours, really appreciate any help!
js
$('a.navLink').on('click', function() {
var cat = $(this).data("cat");
console.log(cat);
$.ajax({
url: 'scripts/categoryGet.php',
type: 'POST',
dataType: "json",
data: {'cat': cat},
success: function(data) {
var title = data[0][0],
description = data[0][1];
console.log(title);
$('#categoryTitle').html(title);
$('#categoryTitle').trigger("refresh");
$('#categoryDescription').html(description);
$('#categoryDescription').trigger("refresh");
}
});
});
Im getting the correct responses back on both console logs, so I know the works, but neither divs categoryTitle or categoryDescription are being updated. I've tried .trigger('refresh'), .trigger('updatelayout') but no luck!
This was not intended to be an answer (but I can't comment yet.. (weird SO rules)
You should specify in the question description that the above code IS working, that your problem occurs WHEN your playing back and forth on that page/code aka, using the JQM ajax navigation.
From what I understood in the above comment, you're probably "stacking" the ajax function every time you return to the page, thus getting weird results, if nothing at all.
Is your example code wrapped into something ? If not, (assuming you use JQM v1.4) you should consider wrapping it into $( 'body' ).on( 'pagecontainercreate', function( event, ui ) {... which I'm trying to figure out myself how to best play with..
Simple solution to prevent stacking the ajax definition would be to create/use a control var, here is a way to do so:
var navLinkCatchClick = {
loaded: false,
launchAjax: function(){
if ( !this.loaded ){
this.ajaxCall();
}
},
ajaxCall: function(){
// paste you example code here..
this.loaded = true;
}
}
navLinkCatchClick.launchAjax();
function ajaxRequest(){
$.ajax({
type: 'GET',
url: 'client/orders/send_mail_to_notaries',
data: { subject: "hi" }
});
return false;
}
It doesn't pass any params in controller.Can any one trigger this out?
Following the question that you have asked today morning page.replace_html method in rails 2 i guess you are using prototype.
Can you check if jQuery is included? Unless jQuery is included this ajax request will not work.
I just tried the method you're using and it worked for me. Perhaps there's a problem with the router/controller?
When debugging ajax it's very handy to use the Chrome developer toolbar. Bring it up, run the javascript and see what happens.
To see the response from the server you can then flip to the Network tab to see what the response is.
I am facing a problem with getting a response in fetch function of backbone.js. I am using Backbone.js with rails.
$(document).ready(function(){
window.projectPerformanceReport.fetch({
success: function(e) {
$("#loading").hide();
window.questionListView = new QuestionListView;
window.questionListView.render();
window.headerView = new HeaderView;
window.headerView.render();
},
error: function() {
alert("Error");
}
});
});
There is already a URL set for the fetch method and it does make a request to online server which returns a JSON object. I checked by hitting that request independently in new tab and it worked fine. Also the JSON object returned is valid. But when i run this page i always get popup of 'Error'?
Any help would be great.
Thanks
Okay
I got what was the issue..... The thing that was happening was, The Java_Servlet which i was calling to get the JSON object was returning the data in text format instead of JSON... (But it was a valid JSON string)... and while calling the ajax method i had set the type as 'json' so it was failing.
Thanks to everyone who read my question and thought for a solution.
But one strange thing which i observed was, same code was working in production and not in my local machine??? Does anyone have some idea on why it could be behaving like that..???
Thanks :) Now i can sleep properly!!
I use Rails3, JQuery and will_paginate gem to make remote pagination links. Known solution for this is:
$('.pagination a').live('click',function (){
$.getScript(this.href);
return false;
});
With this code I get links like: http://localhost:3000/products?_=1300468875819&page=1 or http://localhost:3000/products?_=1300468887024&page=2. So the little question is: what is this strange param _=1300468887024 (looks like Unix-time). What is its purpose? As I know this can cause some problems with search crawlers.
UPD: The solution is described here.
it's a cache buster. It's also used in development mode, so to avoid getting an old request from the browser cache.
(unfortunately, all the explanations I found are realated to advertisement :S)
This is a simple solution if you don't mind removing it for all requests:
jQuery.ajaxSetup({ cache: true });
Another solution would be to extend jQuery's getScript function as per the documentation:
jQuery.cachedScript = function(url, options) {
options = $.extend(options || {}, {
dataType: "script",
cache: true,
url: url
});
return jQuery.ajax(options);
};
This way, only the ajax calls using this new method will use the cache. On the other hand, if you used the ajaxSetup method, all your ajax calls would cache by default since ajaxSetup sets the cache property globally.
Now you can use $.cachedScript(location.href); instead of $.getScript(this.href);.
I have a form I wish to submit via ajax usind the jQuery $.post command.
The form looks like this:
<form action="/wine/merlot/reviews" class="new_review" id="new_review" method="post">
And the jquery call is:
$(document).ready(function() {
$('#new_review').submit(function() {
$.post($(this).attr('action'), $(this).serialize(), null, 'script');
return false;
});
});
I get the following error on the server:
ActionController::MethodNotAllowed (Only get, put, and delete requests are allowed.):
From what I can tell by digging in with firebugs console the problem is the post is posting to this url:
/wine/merlot instead of /wine/merlot/reviews
I can't for the life of me figure out why this is the case.
OK. It turns out I'm an idiot. I had another div on the page with the id "new_review" so I guess it was looking at the wrong element. Renamed and everything working now.
I could not get a form to submit via ajax using the jQuery $.post command with Rails 2.
I modified Ryan Bates' Railcast 136 to submit via a put instead. The kludge I used was to check the (params[:id] == 'update') in the update action to check for this ajax request.
episode-136/store/public/javascripts/application.js
jQuery.fn.blurWithAjax = function() {
this.blur(function() {
// GOOD .ajax javascript update action works even though create on Rails2 does not
jQuery.ajax({
type: "PUT",
url: "/reviews/update",
data: jQuery(this).serialize(),
dataType: "script",
callback: null
});
return false;
})
return this;
};
jQuery(document).ready(function() {
jQuery("#review_content").blurWithAjax();
});
You need to make the parallel changes also;
def create => def update
app/views/reviews/create.js.erb => app/views/reviews/update.js.erb
Not sure, but try /wine/merlot/reviews/ instead of /wine/merlot/reviews?
