I am using jQuery Address plugin, and all my ajax navigation is based on it, and more precisely on internalChange or externalChange events like that
$(document).ready(function() {
initDeepLinking();
});
function linkClicked(e){
var request = $.ajax({
url: e.path,
data: e.queryString,
type: "GET",
dataType: "json",
});
request.done(handleResponse);
return false;
}
function handleResponse(response, textStatus, jqXHR){
$('#main').html(response.responseText);
};
function initDeepLinking(){
$.address.internalChange(function(event){
linkClicked(event);
});
$.address.externalChange(function(event){
linkClicked(event);
});
}
so when i click on a link leading to the current page, nothing happens.
I would like the page to reload when I do that. Any simple options ?
Thanks !
I am having troubles understanding what your question really is:
you don't know how to attach a handler to the link
you don't know what statement can be used to refresh the current page
In order to set a handler you can use some selector. For example, getting the element by class. More about jquery selectors here.
After you have the element, you can attach an event handler for the 'on click' event and do something like this:
window.location.reload(true);

I try to call $.ajax to get my bootstrap modal's html text. Something like this
$.ajax({
url: ...,
success: function(data){
$("#modal_div").html(data.html);
$("#myModal").modal("show");
}
});
And I have already included bootstrap.min.js in my base html. Btw, I also tried to use a button included in "data.html" to toggle modal, however, I could only see button appended after #modal_div, but couldn't make modal to show up after clicking on the button.
Thank you for your help in advance :)
I found out a way to work around.
If any code are working on newly appended element, put codes inside $(document).ready.
For example (according to my question)
$.ajax({
url: ...,
success: function(data){
$("#modal_div").html(data.html);
$(document).ready(function(){
$("#myModal").modal("show");
}
}
});
When I use
$('body').html(data1)
or
$('html').html(data1)
in AJAX, then any HTML tag or jQuery function does not work on the loaded page.
$.ajax({
type:"GET",
dataType: 'html',
url: 'hell.php',
success : function(data1) {
alert(data1);// will alert "ok"
$('body').html(data1);
},
});
The events you attached before $('body').html(data1) will not fire simply because the elements previously in the body will not exist anymore.
You have to re-attach the events or use .on() method and attach events directly to document.
better use jQuery live function, when attaching event handlers.
See: http://api.jquery.com/live/
First, define the functionality you want to attach to the loaded elements in a function, e.g.:
function attachEventsAfterAjax(){
$('.aLoadedElement').on('click', function(){
console.log('Yay!');
return false;
});
}
Then, after you've loaded your new content, call that function, e.g.:
$.ajax({
[...],
success: function(data){
// Don't replace the <body> HTML, that's not a good idea
// $('body').html(data);
$('#container').html(data);
// Now attach the functionality!
attachEventsAfterAjax();
}
});
Well this has me well and truly stumped. After searching for the last few hours I still cannot seem to work out where I am going wrong.
I am trying to append an AJAX response to a container when it gets clicked. That works fine but I don't want it to append another object when the elements from the AJAX response also gets clicked.... so:
<div id="container">
<!-- AJAX response to get inserted here, for example -->
<span id="ajaxResponse"></span>
</div>
Here is my script:
$('#container').click(function(e) {
var current_el = $(this).get(0);
$.ajax({
url: 'text.html',
success: function(data) {
$(current_el).append(data);
}
});
return false;
});
So it works fine but for some reason the click event on #container also fires when I click on the AJAX response span!?
According to jQuery documentation:
To stop further handlers from
executing after one bound using
.live(), the handler must return
false. Calling .stopPropagation() will
not accomplish this.
But unless I am mistaken, I am calling false? :(
Anyone help me out on this?
UPDATED:
So the only way I can get it to work is by updating my code to this:
$('#container').live('click', function() {
var current_el = $(this).get(0);
$.ajax({
url: 'text.html',
success: function(data) {
$(current_el).append(data);
}
});
});
$('#ajaxResponse').live('click', function(e) {
return false;
});
This seems a little messy though... anyone have a better solution?
Where is live part you mention in the title of the question ?
It is how the event model works.. If you click on element which does not handle the event, the event will travel up the DOM hierarchy until it finds an element that handles the click (and stops its propagation..). Otherwise you would not be able to put an image inside a <a> tag and click on it..
You can bind a canceling handler on the inner element assuming you have someway to target it..
$.ajax({
url: 'text.html',
success: function(data) {
$(current_el).append(data);
// assuming the returned data from ajax are wrapped in tags
$(current_el).children().click(function(){ return false;});
}
});
I think the return false is referring to something else in this case...
you should try calling stopPropagation() - this should stop the "click" function from propagating down to the ajaxResponse span....
One option that you may want to try is switching over to using live(). Essentially, the click event you setup is calling bind(), and the solution you referenced is using live() which is a variation on bind().
For example:
$('#container').live("click", function(e) {
var current_el = $(this).get(0);
$.ajax({
url: 'text.html',
success: function(data) {
$(current_el).append(data);
}
});
return false;
});

This is a mock of what I'm doing:
function loadPage(pn) {
$('#'+pn).live('pagecreate',function(event, ui){
$('#'+pn+'-submit').click( function() {
$.mobile.changePage({
url: 'page.php?parm=value',
type: 'post',
data: $('form#'+pn+'_form')
},'slide',false,false);
loadAjaxPages(pn);
});
});
function loadAjaxPages(page) {
// this returns the page I want, all is working
$.ajax({
url: 'page.php?parm=value',
type: 'POST',
error : function (){ document.title='error'; },
success: function (data) {
$('#display_'+page+'_page').html(data); // removed .page(), causing page to transition, but if I use .page() I can see the desired listview
}
});
}
in the ajax call return if I add the .page() (which worked in the past but I had it out side of the page function, changing the logic on how I load pages to save on loading times), make the page transition to the next page but I can see the listview is styled the way I want:
$('#display_'+page+'_page').html(data).page();
Removing .page() fixes the transition error but now the page does not style. I have tried listview('refresh') and even listview('refresh',true) but no luck.
Any thoughts on how I can get the listview to refresh?
Solution:
$.ajax({
url: 'page.php?parm=value',
type: 'POST',
error : function (){ document.title='error'; },
success: function (data) {
$('#display_'+page+'_page').html(data);
$("div#name ul").listview(); // add div wrapper w/ name attr to use the refresh
}
});
Be sure to call .listview on the ul element
If it didn't style earlier, you just call .listview(), bot the refresh function. If your firebug setup is correct, you should have seen an error message telling you that.
I didn't have time to get down to creating some code before you posted your fix, but here's a little recommendation from me:
if(data !== null){ $('#display_'+page+'_page').html(data).find("ul").listview() }
This is a bit nicer than a new global selector. Also - you don't need the div and you can provide a detailed selector if you have multiple ULs.
caution: the above code requires data !== null. If it's null - it will throw an error.
If you add items to a listview, you'll need to call the refresh() method on it to update the styles and create any nested lists that are added. For example:
$('#mylist').listview('refresh');
Note that the refresh() method only affects new nodes appended to a list. This is done for performance reasons. Any list items already enhanced will be ignored by the refresh process. This means that if you change the contents or attributes on an already enhanced list item, these won't be reflected. If you want a list item to be updated, replace it with fresh markup before calling refresh.

I'm trying to do an ajax post after a button is clicked, and it works in firefox but not in IE the first time the page is loaded. It does work if I refresh the page and try again second time - but not first time and this is crucial.
I've scanned over various web pages - could it be anything to do with the listener? (I've just seen this mentioned mentiond somewhere) Is there something not set correctly to do with ajax and posting when page first loads?
$(document).ready(function() {
$('#btnCont').bind('click',function () {
var itm = $("#txtItm").val();
var qty = $("#txtQty").val();
var msg = $("#txtMessage").val();
var op_id = $("#txtOp_id").val();
//if i alert these values out they alert out no prob
alert(itm+'-'+qty+'-'+msg+'-'+op_id);
$.ajax({
type: "POST",
url: "do_request.php?msg="+msg+"&itm="+itm+"&qty="+qty+"&op_id="+op_id,
success: function (msg) {
document.getElementById('div_main').style.display='none';
document.getElementById('div_success').style.display='block';
var row_id = document.getElementById('txtRow').value;
document.getElementById('row'+row_id).style.backgroundColor='#b4e8aa';
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert('Error submitting request.');
}
});
});
I would start debugging the click event. I.e. if you try to put .bind into a a href tag, the tag itself has a click event that may act on an unwanted way. There exist a command that are named something like event.preventDefaults() that avoids the standard feature of click. After All, you try to manipulate the DOM last of all actions (document.load).
$('#btnCont').bind('click',function () { .. }
I would also try to debug the same functionality with adding onClientClick to the tag instead of adding bind to the document load.
I hope that bring some light.
