I have used framework built-in formToJSON() to get the form values. I have used click event to console the value.
$$("#query-submit").on("click", function () {
var queryForm = app.formToJSON("#query-form");
console.log(JSON.stringify(queryForm));
});
It works fine when page loads first time. But if I changed navigation to other page and return back to first page.
On debug, I found click event is not working when I went back to form page.
Also found this warning in console.
What is wrong here.
Note All pages were loaded via AJAX
Try this:
$$(document).on('click', '#query-submit', function(){
// your code
});

Below is a model of jquery.ajax() success behaviour.
Shortly: I managed to fetch data via AJAX. In this model example the data is represented by "Just something" placeholder. Now I want to add the data to the document.
<script>
var add_date = $("#add_date");
function add_date_ajax(){
$('.frame_date').append("Just something");
debugger; // 1
}
debugger; // 2
add_date.click(add_date_ajax);
</script>
A problem: the data appear and then disappear in half a second.
I placed breakpoints.
When the page is loading, it stops at breakpoint 2. That is correct.
When I click #add_date element, the script stops at breakpoint 1. That is also correct.
But when I click "resume script execution", the script again goes to breakpoint 2. This seem strange to me. As if the page is reloaded. Maybe that is why the added text disappears.
Could you help me cope with the problem?

It disappears because you are reloading the page. The html
Add date
should be
Add date
To bind all your events, you should use the ready on document.
To avoid the reloading of your page (because of the href of the a tag), you have to call preventDefault or use a button.
You should write your code like this:
$(document).ready(function() {
$("#add_date").on("click", add_date_ajax);
});
function add_date_ajax(event) {
event.preventDefault();
$('.frame_date').append("Just something");
}
I have a multi-page form where the url remains the same when moving between pages.
I am trying to change some HTML after the submit button has been clicked.
I can run this in the console and the result is as I want it.
How can I get this run after submit?
I've tried window.onload and document.onload functions but they are not working. I've also tried an onclick function but it seems moving to the next page stops this working?
var confirm = document.getElementById('gform_confirmation_message_14');
if(confirm) {
document.getElementsByClassName("entry-title")[0].innerHTML = "PAYE Worker";
}
Thanks
Perhaps the gform_page_loaded event? From the documentation it:
Fires on multi-page forms when changing pages (i.e. going to the next or previous page).
$(document).on('gform_page_loaded', function(event, form_id, current_page) {
// do stuff
});
There are a bunch of javascript events available, and if not this one, maybe another serves your purpose, e.g. gform_post_render.
I removed the Javascript completely and created a confirmation in Gravity Forms that redirects to a new page upon submission.
Created a title for this new page "PAYE worker"
Problem solved
Ok this thing is driving me crazy. I have a simple project in which I use this mobile bootstrap theme and this text-to-speech library
Whenever there's an error in my function, the page just refreshes itself. In this way I can never read any output from the console.
Here's my code:
<script>
$(document).ready(function() {
$('#input-submit').click(function() {
var text = $('#input-box').val();
console.log(text);
for (var i = 0;i < text.length; i++){
alert('test');
meSpeak.speak(text.charAt(i));
}
});
});
</script>
I want my app to spell out loud whatever the user fills in. The function works correctly until the meSpeak.speak(text.charAt(i)); line. When I type in a 3 character word I get 3 alerts, and then the page just refreshes itself.
Why does it refresh when there's something not working? I want to read the output from the console without using alerts. Also, does anyone know why I can't use meSpeak.speak(text.charAt(i)); like this?
You're not preventing the submit button from "submitting" the page, and as you've most likely set no destination, it's submitting to the same location, causing a page refresh.
Preventing the click event can be done in jQuery by returning false at the end of the function
$('#input-submit').click(function () {
/* etc */
return false;
});
Demo to play with
I am trying to avoid my page being refreshed after submitting my form. In order to do this I've added into my javascript section
$("body").on('click',"#register",new_user_pop);
$("body").on('click',"#screen",pop_out);
$("body").on('click',"#new-user",pop_registration);
$('form[name=new-user-form]').on('submit',function(event) {
event.preventDefault();
alert("Not refreshing");
The function works properly as in order to debug it I pasted it on the Terminal from the Chrome's developer tools and it started working.
But for some reason I do not know it does not work it does not get loads at the beginning.
The previous function $("body").on('click')... work all fine.
Make sure your code runs after you've defined the HTML elements you want to attach your events to.
You can either do this by placing your script below the HTML bit you need.
Or you can wrap your code in an onready/load callback:
$(document).ready(function () {
/* code goes here */
});
I am using jQuery Mobile to create a site, in the index page I placed here a form for a search. I hooked submit event for ajax post. When ajax success get the resource
(html,<ul>...</ul>), placed in the target container, then trigger the create event for enhance the view. This work fine in the first time. When I click back to index page and search again I got a raw listview without enhance, who can tell me why? ps: I have tried many methods but there is more and more problem, the official document was so poor.
$(document).bind('pageinit',function(){
$("#search").submit(function(){
var searchdata = $("#search").serialize();
$.ajax({
'type':"POST",
'url':"/server/jnulib.php?action=search",
'data':searchdata,
'success':function(data){
$("#searchresultfield > ul").remove();
$("#searchresultfield").html(data).find('ul').trigger('create');
try{
$("#searchresultfield > ul").listview('refresh');
}catch(e){
}
$.mobile.changePage("#searchresult");
//$("div[data-role='header'] > a").
}
});
return false;
});
});
EDIT： Test Url： http://ijnu.sinaapp.com
Another problem: the second ajax request failed and the browser navigate to the ajax target straightly.
You could try changing:
$("#searchresultfield").html(data).find('ul').trigger('create');
to:
$("#searchresultfield").html(data).find('ul').listview().listview('refresh');
Anytime you append or remove elements you need to refresh, and if you remove the whole list, you need to reinitialize it.
Also I have had issues with listview('refresh') rendering improperly if it was not visible.
$(document).on('pageshow','div',function(event, ui){
if($("#searchresultfield > ul").is(":visible")) $("#searchresultfield > ul").listview('refresh');
});
For me, .trigger('create'); always works if applied to the element with data-role="page"
For example
HTML Code
<div data-role="page" id="somePage">
...
</div>
Javascript Code
$('#somePage').trigger('create');
Hope it helps
Try:
$("#searchresultfield > ul").empty();
instead of
$("#searchresultfield > ul").remove();
I think the problem is that jquery mobile loads all pages despite all being from different files into one big page and navigation is based off going to different points in this page, so that when you go onto it the first time the page you access is considered created however when clicking the back button and navigating away from the page that page is still considered created so the event well not fire again,
What I used was:
$('#oppList').live('pageshow',function(event){
getList();
});
Where #opplist is the id of the data-role="page" for the page I just load, this does not matter whether this happens the first time the page is loaded or after because the event is fired whenever the page is displayed.

Hope this helps !
Maybe you should try to unhook the submit event once it's been handled. And initiate it again once you go back to the page where you were before. Adding eventhandlers multiple times can cause a lot of problems.
