I am trying to pass two arguments thought ajax. The variables I am pulling from are in a div and are done on the fly. I can easily pass the date_time but I need to be able to pass a variable "id" also. The date is in an array that is being loaded and changes. The ID does not change for this page.
This is the javascript. Below that will be my div. All attempts to append this have failed. Any ideas?
<div class='letter' width=600 date_time=\"$date_time\" id=\"$id\">
....doing stuff here.....
</div>
function OnScrollLetters () { var div = document.getElementById ("userLetter");
var info = document.getElementById ("info");
if(div.scrollTop == (div.scrollHeight - div.clientHeight))
{
$('div#loadMoreComments').show();
$.ajax({
url: "get_letters_for_profile_scroll.php?lastComment="+ $(".letter:last").attr('date_time'),
success: function(html) {
if(html){
$("#userLetter").append(html);
$('div#loadMoreComments').hide();
}else{
$('div#loadMoreComments').replaceWith("<center><h1 style='color:red'>End of Letters</h1></center>");
}
}
});
}
}
This is my div.
<div class='letter' width=600 date_time=\"$date_time\" id=\"$id\">
....doing stuff here.....
</div>
Try place a "=" between parameter name and value
..."&id="+$(".letter:last").attr('id')

I have an issue with observables being fired after content is updated via ajax and javascript is re-initialized via .trigger('contentUpdated'). This all works when the scripts are rendered initially on page load but when they are added via ajax I cannot get the observables to update. For demo purposes I've simplified by logic but basically I have a block that gets loaded via ajax for a product collection like so:
myblock.phtml
<div class="wrapper-id-1">
<!-- this is what gets appended via ajax
<div id="product-item-<?php echo $productId;?>">
<span data-bind="text: someObservable()"></span>
...
</div>
<script type="text/x-magento-init">
{
"#product-item-<?php echo $productId;?>": {
"path/to/component":{
"some":"vars"
}
}
</script>
<!--and ajax append ends here -->
</div>
In the component that gets bound to the element I have:
component.js
...
this.someObservable: ko.observable('default value'),
initialize: function () {
var self = this;
this.anotherComponentModel().value.subscribe(function(data){
self.someObservable(data['value']);
},this);
},
...
the ajax that calls and loads the collection:
ajaxComponent.js
$.ajax({
url: 'route/to/controller?cat=' + categoryId,
success: function (data) {
$('.wrapper-id-' + categoryId).empty().append('<h2>' + categoryTitle + '</h2>' + data).show().trigger('contentUpdated');
}
})
...
I see that the component(component.js) gets initialized when contentUpdated is triggered and it has all of the correct data that is needed. However the observables to not fire and the data is not updated to the DOM. This an issue with scope? Or to I need to re-initialize the observables? I tried doing this via not binding directly to the component ie:
<script type="text/x-magento-init">
{
// components initialized without binding to an element
"*": {
"<js_component3>": ...
}
}
</script>
but it achieves the same result.
What am I missing here.
I have some code, some to change the class of a div, the rest to load content into the ajax div.
The ajax div however, does not load content. Why might this be?
<script>
window.onload = function () {
var everyone = document.getElementById('everyone'),
favorites = document.getElementById('favorites');
everyone.onclick = function() {
loadXMLDoc('indexEveryone');
var otherClasses = favorites.className;
if (otherClasses.contains("Active")) {
everyone.className = 'statusOptionActive';
favorites.className = 'statusOption';
}
}
favorites.onclick = function() {
loadXMLDoc('indexFav');
var otherClasses = everyone.className;
if (otherClasses.contains("Active")) {
favorites.className = 'statusOptionActive';
everyone.className = 'statusOption';
}
}
function loadXMLDoc(event) {
$.ajax({
url: "../home/" + event.data + ".php",
type: "GET",
success: function (result) {
$("#centreCont").html(result);
}
});
}
}
</script>
These divs start the ajax code (or should do at least)
<div id="everyone" class="statusOptionActive" onclick="loadXMLDoc('indexEveryone')">Everyone, everywhere</div>
<div id="favorites" class="statusOption" onclick="loadXMLDoc('indexFav')">Favourites Only</div>
Why won't it work :(
DEMO
Delete your div onclick event,since already you are manipulating your click event in the script.
Edited div
<div id="everyone" class="statusOptionActive">Everyone, everywhere</div>
<div id="favorites" class="statusOption">Favourites Only</div>
And I don know what argument you are passing in to loadXMLDoc('indexFav'); and loadXMLDoc('indexEveryone'); apart from that your javascript code is correct.
Hope this helps
Thank you
One obvious problem I can see is that you pass a string to loadXMLDoc, then you try to access .data on that string.
I am getting next page on my wordpress blog using jquery, finding the desired div and appending it to the existing one. This part works without a problem. But, what I need to do is, to add slideDown animation to it.
This is how my working code so far looks like:
$.get(next_page, function(data) {
var response = $(data);
var more_div = $(response).find('.FeaturedRow1').html();
$('.FeaturedRow1').append(more_div).slideDown('slow');
$('.navigation').not(':last').hide();
I tried adding hide() to response, more_div as well as append lines. In the first case, I get error stating that it cannot set property display of undefined.
In the second case, in the console it display HTML and says "has no method hide". I also tried adding a line $(more_div).hide() but again, I get the error "Uncaught TypeError: Cannot set property 'display' of undefined".
If I use hide in the 3rd line
$('.FeaturedRow1').hide().append(more_div).slideDown('slow');
it hides the whole FeaturedRow1 div and animates it, that takes me to the top of the div, which is what I don't want.
EDIT: Here's the important HTML structure and jQuery code for the desired section
<div class="FeaturedRow1">
<div class="postspage">
//list of posts here
</div>
<div class="navigation">
<span class="loadless">
//hyperlink to previous page
</span>
<span class="loadmore">
//hyperlink to next page
</span>
</div>
</div>
When you click on the hyperlink inside the loadmore, the following jQuery code gets called
$('.loadmore a').live('click', function(e) {
e.preventDefault();
var next_page = $(this).attr('href');
$.get(next_page, function(data) {
var $response = $(data);
var $more_div = $response.find('.FeaturedRow1').hide();
$more_div.appendTo('.FeaturedRow1').delay(100).slideDown('slow')
$('.navigation').not(':last').hide();
});
});
$('.loadless').live('click', function(e) {
e.preventDefault();
if ($('.postpage').length != 1) {
$('.postpage').last().remove();
}
$('.navigation').last().remove();
$('.navigation').last().show();
});
You get error as you are using html method which returns a string not a jQuery object, try the following.
var $response = $(data);
var $more_div = $response.find('.FeaturedRow1').hide();
$more_div.appendTo('.FeaturedRow1').delay(100).slideDown('slow');
//$('.navigation').not(':last').hide();
Update:
$.get(next_page, function(data) {
var $response = $(data);
var more_div = $response.find('.FeaturedRow1').html();
$('<div/>').hide()
.append(more_div)
.appendTo('.FeaturedRow1')
.delay(100)
.slideDown('slow')
$('.navigation').not(':last').hide();
});
I'm trying to load content from another page div into another page div.
What i've got:
JQUERY:
$('#news_date-1').load('test.php .news_date-1');
TEST.PHP
<div class="news_date-1">20-11-2009</div>
Destination.html
<div id="news_date-1"></div>
The result i get =
<div id="news_date-1"><div class="news_date-1">20-11-2009</div></div>
The result i want =
<div id="news_date-1">20-11-2009</div>
Can anybody help out?
You can try calling unwrap() on it in the callback.
$('#news_date-1').load('test.php .news_date-1', function () {
$(this) //will refer to #news_date-1
.find('.news_date-1') //find the inserted div inside
.contents() //find all its contents
.unwrap(); //unwrap the contents, thus removing the unneeded div
});
This is not the most beautiful solution, because .load() already inserts it into the DOM, and then you tamper with the DOM again, which should be minimized.
Another way I see is using $.get() instead:
$.get('test.php', function(receivedHtml) {
//getting only the parts we need
var neededHtml = $(receivedHtml).find('.news_date-1').html();
//adding it to DOM
$('#news_date-1').append(neededHtml);
});
Try this:
$.get('test.php', function(data) {
$('#news_date-1').append($(data).find('.news_date-1'));
});
I am using Ajax and Prototype. In my code, I need to update the contents of a div.
My div:
<div id="update">
1. Content_1
</div>
My code:
Element.update($("update"),"2.Content_2");
Expected output:
<div id="update">
1.Content_1
2.Content_2
</div>
How can I do this in Ajax and Prototype?
AJAX usually means you are executing a script on the server to get this result.
However, in your example it looks like you simply want to append some text.
To append text you could simply add the text to the end of the innerHTML:
$("update").innerHTML = $("update").innerHTML + "2.Content_2";
If you are wanting to execute a server script, I'd do this: (I haven't used Prototype for a while, things might have changed)
function getResult()
{
var url = 'theServerScriptURL.php';
var pars = '';
var myAjax = new Ajax.Request(
url,
{
method: 'post',
parameters: {},
onComplete: showResult
});
}
function showResult(originalRequest)
{
$("update").innerHTML = originalRequest.responseText;
}
This code will call 'theServerScriptURL.php' and display the result in the div with id of 'update'.
