Is there a JQuery plugin that allows me to 'unhide' a form by after clicking a link? Like I have an invite link that can take me to a one text field form for an email address but I want this form to just drop down (pushing the rest of the content down also) and shows the form to submit the email. If you guys can think of a JQuery plugin that lets me do this, please let me know
Edit:
So I did this
<div class='add-link'>
<div id='invite_link'><a href=''>Invite User</a></div>
<div id='invitation_form'>
<form>
<input type='text'/>
</form>
</div>
</div>
and my jquery looks like
<script type="text/javascript">
$(function()
{
$("table").tablesorter({sortList:[[0,0],[2,1]], widgets: ['zebra']});
$('#invitation_form').hide();
}
);
$('#invite_link').click(function() {
$('#invitation_form').slideDown();
});
Do you guys see any error that causes the form not to slide down. It hides the form when the page loads but when I click the link it is not sliding down.
$('a.mylink').click(function() {
$('#MyForm').slideDown();
});
I don't think you need a jQuery plugin for this. The base jQuery library should be sufficient.
$('#showFormLink').click(function () {
$('#form').slideDown();
});
If you're looking for animation, that's possible as well by passing in a duration argument to slideDown.
Take a look at the jQuery show documentation.

I have a Razor/ASP/MVC3 web application with a form and a Submit button, which results in some action on the server and then posts back to the form. There is often some delay, and it's important that users know they should wait for it to complete and confirm before closing the page or doing other things on the site, because it seems users are doing that and sometimes their work has not been processed when they assume it has.
So, I added a "Saving, Please Wait..." spinner in a hidden Div that becomes visible when they press the Submit button, which works very nicely, but I haven't been able to find a way to get the Div re-hidden when the action is complete.
My spinner Div is:
<div id="hahuloading" runat="server">
<div id="hahuloadingcontent">
<p id="hahuloadingspinner">
Saving, Please Wait...<br />
<img src="../../Content/Images/progSpin.gif" />
</p>
</div>
</div>
Its CSS is:
#hahuloading
{
display:none;
background:rgba(255,255,255,0.8);
z-index:1000;
}
I get the "please wait" spinner to appear in a JS method for the visible button, which calls the actual submit button like this:
$(document).ready(function () {
$("#submitVisibleButton").click(function () {
$(this).prop('disabled', true);
$("#myUserMessage").html("Saving...");
$("#myUserMessage").show();
$("#hahuloading").show();
document.getElementById("submitHiddenButton").click();
});
});
And my view model code gets called, does things, and returns a string which sets the usermessage content which shows up fine, but when I tried doing some code in examples I saw such as:
// Re-hide the spinner:
Response.write (hahuloading.Attributes.Add("style", "visibility:hiddden"));
It tells me "hahuloading does not exist in the current context".
Is there some way I am supposed to define a variable in the view model which will correspond to the Div in a way that I can set its visibility back from the server's action handler?
Or, can I make the div display conditional on some value, in a way that will work when the page returns from the action?
Or, in any way, could anyone help me figure out how to get my div re-hidden after the server action completes?
Thanks!
Is this done with ajax? I would assume so because the page is not being redirected. Try this:
$(document).ready(function () {
$("#submitVisibleButton").click(function () {
$(this).prop('disabled', true);
$("#myUserMessage").html("Saving...");
$("#myUserMessage").show();
$("#hahuloading").show();
document.getElementById("submitHiddenButton").click();
});
$("#hahuloading").ajaxStop(function () {
$(this).hide();
});
});
As an aside, you no longer need runat=server.
i'm trying to upload a file trough iframe.
i create the iframe in this way:
<iframe frameBorder="0" height="50px" width="100%" id="iframe-upload"/>
after this i append the iframe to the DOM:
$('#iframe-upload').contents().find('body').append('<form method="post" action="admin/images/upload" enctype="multipart/form-data" id="form-upload-image"><input name="data[image]" type="file" id="image-upload" /><input type="button" id="btn"></form>').appendTo("#formupload");
to submit i act like this:
$("#iframe-upload").contents().find('#btn').bind('click', function(){
$("#iframe-upload").contents().find('#form-upload-image').submit()
})
now, i cannot figure out WHEN i have to call:
console.log($("#iframe-upload").contents());
to get the content.
The problem is sync between my contents() request and iframe refresh, actually jquery goes first, and AFTER the iframe refreshes. In this way i cannot reach the real response.
p.s.
i've tried live(), on(), change() con the frame content, but all these events fires up only one time ( when i select the file before submitting the form ) and so are useless
thank you in advice
You should be able to grab the contents from the iframe before submitting the form. To achieve this, you can bind a function to the form's onSubmit event.
$('#form-upload-image').bind('submit', function (event) {
event.preventDefault();
console.log($("#iframe-upload").contents());
this.submit();
});
or possibly
$('#form-upload-image').submit( function () {
console.log($("#iframe-upload").contents());
});
This is just off the top of my head.
Check the contents after the iframe is loaded.
$('#iframe').load(function () {
$(this).contents();
});
EDIT italics = more detailed explanation added to the question. Thanks.
I'm building a jQuery Mobile site which has a Gallery section.
The gallery has a series of thumbnails on the top of the screen.
Users click on the thumbnail to load in new content, that being a larger image, text, and potentially audio on some of them.
It's at this point that I'm not sure what to do: the way jQuery Mobile works, it's geared towards loading new pages, or views. But I just want to inject new content in a container on the current page.
To be clear, when the user clicks on another thumbnail, a new image replaces the content of the container with new content.
I have two questions:
I'm not sure how to structure the dynamic content. I was thinking i'd create an html file for each item, which as a rule always contains a title, information and sometimes, audio.
I'm not sure how to script this functionality in jQuery Mobile. It's obviously Ajax, but I'm not familiar with it yet, especially since jQuery Mobile has it's own methods in place already which seems to redefine behaviors in a way that's contradictory to this approach described here.
Here is a code explanation of what i'm trying to do:
<!-- Galleries -->
<div data-role="page" id="galleries">
<div data-role="content" role="main">
This is the Selection UI, if i click on thumb2.jpg, it'd
fill #content-holder with the whatever html is in content2.php
<div id="thumb-carousel">
<img src="thumb1.jpg">
<img src="thumb2.jpg">
<img src="thumb3.jpg">
<img src="thumb4.jpg">
<img src="thumb5.jpg">
<img src="thumb6.jpg">
<img src="thumb7.jpg">
<img src="thumb8.jpg">
<img src="thumb9.jpg">
</div>
<!-- This is the container, currently it's filled
with the kinda stuff i need to put in it. -->
<div id="content-holder">
<img src="myimage1.jpg"/>
<p>Artwork Title</p>
<p>Caption</p>
<audio>//mp3</audio>
</div>
</div>
</div>
//remember to use event delegation because you never know when the page will be in the DOM
$(document).delegate('#galleries', 'pageinit', function () {
//bind a `click` event handler to each thumbnail link
$('#thumb-carousel').children().bind('click', function () {
$.ajax({
url : $(this).attr('href'),
success : function (serverResponse) {
//select the container,
//then fade it out,
//change it's HTML to the response from the AJAX request,
//and fade it back in
$('#content-holder').fadeOut(500, function () {
$(this).html(serverResponse).fadeIn(500);
});
},
error : function (jqXHR, textStatus, errorThrown) {
//remember to handle errors so your page doesn't seem broken to the user
}
});
//prevent the default behavior of the link, which is to navigate to the `href` attribute
return false;
});
});
This expects your server-response to be valid HTML markup that is ready to inject into the DOM, meaning no <html> or <body> tags, just what you want to add to the DOM:
<img src="..." />
<span>TITLE</span>
<audio src="..."></audio>
Here are some docs for ya:
$.ajax(): http://api.jquery.com/jquery.ajax
.closest(): http://api.jquery.com/closest
.fadeIn(): http://api.jquery.com/fadein
I'm experiencing some strange behaviour with checkboxes on a Dojo page. In the code below I have created a search form which makes an Ajax/xhrGet request when the search text is changed - this all works as expected.
However I also have a checkbox on the same page which, when clicked, is also submitting an Ajax request. Since I have not connected the checkbox to the search I have no idea why this is happening.
Is this a bug or is there something more subtle going on here?
Any ideas/suggestions?
TIA,

I found the cause of my problem. Hopefully this will help someone else in the future.
Basically I did not issue the dojo.connect correctly - this needs to be done inside the 'addOnLoad' handler. In my initial code I was issuing the connect request on the page, but not in the required addOnLoad handler. The following code works correctly.
Hopefully this will help someone else in the future.
<script>
// Add the dojo.connect below
dojo.addOnLoad(function() {
// Connection s/b in 'addOnLoad' to work correctly
var srch = dojo.byId ("djsearch");
dojo.connect(srch, "onchange", "getbyname");
});
</script>
I'm trying to set up a basic web page, and it has a small music player on it (niftyPlayer). The people I'm doing this for want the player in the footer, and to continue playing through a song when the user navigates to a different part of the site.
Is there anyway I can do this without using frames? There are some tutorials around on changing part of a page using ajax and innerHTML, but I'm having trouble wrapping my head aroung getting everything BUT the music player to reload.
Thank you in advance,
--Adam
Wrap the content in a div, and wrap the player in a separate div. Load the content into the content div.
You'd have something like this:
<div id='content'>
</div>
<div id='player'>
</div>
If you're using a framework, this is easy: $('#content').html(newContent).
EDIT:
This syntax works with jQuery and ender.js. I prefer ender, but to each his own. I think MooTools is similar, but it's been a while since I used it.
Code for the ajax:
$.ajax({
'method': 'get',
'url': '/newContentUrl',
'success': function (data) {
// do something with the data here
}
});
You might need to declare what type of data you're expecting. I usually send json and then create the DOM elements in the browser.
EDIT:
You didn't mention your webserver/server-side scripting language, so I can't give any code examples for the server-side stuff. It's pretty simple most of time. You just need to decide on a format (again, I highly recommend JSON, as it's native to JS).
I suppose what you could do is have to div's.. one for your footer with the player in it and one with everything else; lets call it the 'container', both of course within your body. Then upon navigating in the site, just have the click reload the page's content within the container with a ajax call:
$('a').click(function(){
var page = $(this).attr('page');
// Using the href attribute will make the page reload, so just make a custom one named 'page'
$('#container').load(page);
});
HTML
<a page="page.php">Test</a>
The problem you then face though, is that you wouldnt really be reloading a page, so the URL also doesnt get update; but you can also fix this with some javascript, and use hashtags to load specific content in the container.
Use jQuery like this:
<script>
$("#generate").click(function(){
$("#content").load("script.php");
});
</script>
<div id="content">Content</div>
<input type="submit" id="generate" value="Generate!">
<div id="player">...player code...</div>
What you're looking for is called the 'single page interface' pattern. It's pretty common among sites like Facebook, where things like chat are required to be persistent across various pages. To be honest, it's kind of hard to program something like this yourself - so I would recommend standing on top of an existing framework that does some of the leg work for you. I've had success using backbone.js with this pattern:

You can reload desired DIVs via jQuery.ajax() and JSON:
For example:
index.php
<script type="text/javascript" src="jquery-1.4.2.js"></script>
<script type="text/javascript" src="ajax.js"></script>
<a href='one.php' class='ajax'>Page 1</a>
<a href='two.php' class='ajax'>Page 2</a>
<div id='player'>Player Code</div>
<div id='workspace'>workspace</div>
one.php
<?php
$arr = array ( "workspace" => "This is Page 1" );
echo json_encode($arr);
?>
two.php
<?php
$arr = array( 'workspace' => "This is Page 2" );
echo json_encode($arr);
?>
ajax.js
jQuery(document).ready(function(){
jQuery('.ajax').click(function(event) {
event.preventDefault();
// load the href attribute of the link that was clicked
jQuery.getJSON(this.href, function(snippets) {
for(var id in snippets) {
// updated to deal with any type of HTML
jQuery('#' + id).html(snippets[id]);
}
});
});
});
