Having troubles with removing and reapearing html elements with jquery

Basically I want to slide down a element, then when the button is hit again I want it to slide up, empty the div, then slide down with the new results. I'v been trying to figure out how to do this for so long and I cant seem to get it working with jquery.
$(".search").on("click",function(){
$('.results').slideUp(500).empty().append("<p>Results</p>").hide().slideDown(500)
});
I understand this is kind of specific to my project kind of but I do feel others might find this useful

I'm not sure what exactly your problem is, but I think the slideUp animation is not shown in your example.
The slideUp method takes a second argument, which is the function callback. It is called when the slideUp action is finished. If you do the rest of your actions in this callback function, is guaranteed to be performed after the slideUp.
jQuery('#testbutton').on('click',function() {
$('#testlist').slideUp(500, function() {
$('#testlist').empty().append("<li>this is a test</li>").slideDown(500);
});
});

want it to slide up, empty the div, then slide down with the new
results.
It seems simple enough to me
let me know if you need anything more
$('#myButton').click(function () {
if ( $( ".myDiv" ).is( ":hidden" ) ) {
//show the div
$( ".myDiv" ).slideDown( "slow" );
//add content
$( ".myDiv" ).html("New Content")
} else {
//hide the div
$( ".myDiv" ).slideUp( "slow" );
//clear content
$( ".myDiv" ).html("");
}
});

Updated the pen with append ability and more readability
$('#myButton').click(function () {
if ( $( ".myDiv" ).is( ":hidden" ) ) {
show();
} else {
hide();
clearContent();
appendContent("New Content");
}
});
function clearContent(){
//clear content
$( ".myDiv" ).html("");
}
function appendContent(content){
$( ".myDiv" ).html($( ".myDiv" ).html()+content);
}
function hide(){
//hide the div
$( ".myDiv" ).slideUp( "slow" );
}
function show(){
//show the div
$( ".myDiv" ).slideDown( "slow" );
}

Drop Down text won't come back up and won't recognize other instances

I used OnClick drop down text with JavaScript and HTML code to make the dropdown hidden div project.
But the problems are:
1 - It won't open divs separatelly, all of the "projects" are open at once;
2 - I won't come back up once I click it again.
I made another line of code to make it go up:
$(function() {
$(".project").on('click', function() {
$(this).parent().find('.details').slideDown();
});
$(".project").on('click', function() {
$(this).parent().find('.details').slideUp();
});
});
$(function() {
$(".project2").on('click', function() {
$(this).parent().find('.details').slideDown();
});
$(".project2").on('click', function() {
$(this).parent().find('.details').slideUp();
});
});
And so on... and it goes up as soon as I click it only once, like an animation. It won't stay down and THEN on the next click it goes back up. AND it still gets both down instead of each one separately.

You shouldn't use document.ready to often if isn't needed.
// Shorthand for $( document ).ready()
$(function() {
});
If you bind two events to an element, .. it will be executed if you don't stopPropergation or making "cases".
So you can check the visibility and decide what to do:
$( function () {
$("[class^='project']").on( 'click', function () {
var $details = $( this ).parent().find( '.details' );
if ($details.is(':visible'))
$( this ).parent().find( '.details' ).slideUp();
else
$( this ).parent().find( '.details' ).slideDown();
});
} );

edit:
slideToggle is more elegant :) #Diego López
$( function () {
$("[class^='project']").on( 'click', function () {
$(this).parent().find('.details').slideToggle();
});
} );
https://jsfiddle.net/3738Lnmf/1/

Use .slideToggle() if you want to toggle between show and hide the div elements
$(function() {
$(".project").on('click', function() {
$(this).parent().find('.details').slideToggle();
});
$(".project2").on('click', function() {
$(this).parent().find('.details').slideToggle();
});
});

Popup window not showing div

I have this JQuery code:
function JQueryPopup(value) {
$(value).toggle();
$('#JQueryClose').click(function(){
$(value).hide();
});
$( document ).on( 'click', function ( e ) {
$(value).hide();
});
$( document ).on( 'keydown', function ( e ) {
if ( e.keyCode === 27 ) { // ESC
$(value).hide();
}
});
}
and a HTML button that calls this function, it doesn't seem to be showing the popup window/div.
here is a fiddle with my full code: http://jsfiddle.net/XHLY8/3/
P.S. i do have this code on another page, i call the function like this:
<script type="text/javascript">JQueryPopup('#customer_popup_notes');</script>
which works fine.

You need to add the following:
$('#inbox_button').on('click', function(event){
event.preventDefault(); // This isn't critical, but you would need
event.stopPropagation();
JQueryPopup('#inbox_div');
});
You want to stop the click event from bubbling up and triggering the following:
$( document ).on( 'click', function { ... });
Otherwise your #inbox_div will be hidden before you can see it.
Here is a working fiddle.
I suggest reading up on stopPropagation and preventDefault.

You dont need
$( document ).on( 'click', function ( e ) {
$(value).hide();
});
Which always hides the Bottom div no matter where u click .

Calling a jQuery function multiple times

So, I have this function in jQuery:
$(function(){
$( ".unfocused" ).click(function ClickHeader () {
$( this ).addClass( "focused" );
$( this ).removeClass( "unfocused" );
$(".header").not(this).addClass( "unfocused" );
$(".header").not(this).removeClass( "focused" );
});
});
It works perfectly when a header is clicked the first time, but when I try to click another unfocused header, the function doesn't work anymore. Is it because it runs on document .ready?
Thanks for your help!

Change it like this:
$( document ).on("click", ".unfocused", function() {
$( this ).addClass( "focused" );
$( this ).removeClass( "unfocused" );
$(".header").not(this).addClass( "unfocused" );
$(".header").not(this).removeClass( "focused" );
});
This basically registers the event on the document. When you click a header, the event bubbles up to the document. There, the given selector is validated and the function is executed if needed.

Here is a jsfiddle using the delegate operation for handling the event like you need.
http://jsfiddle.net/MN9Zt/2/
$("body").delegate(".unfocused", "click", function() {
$(this).addClass("focused");
$(this).removeClass("unfocused");
$(".header").not(this).addClass("unfocused");
$(".header").not(this).removeClass("focused");
});

closing jquery dialog from an iFrame

I have created a jquery dialog with an Iframe in it that's a form and I would like the dialog to close when the user hits cancel's or submits the form in the dialog...
$( "#dialog" ).dialog( "option", "title",["Create"] );
$( "#dialog" ).dialog( "open" );
$("#dialog-content").html("<iframe id='iframe_manage' width='825px' height='800px' class='popup_iframe' src='manage.php?PME_sys_operation=Add&pv=popup'></iframe>");
thoughts?
i tried something like this..
$("#iframe_manage").load(function () {
$('input[name=PME_sys_canceladd]').click(function() {
alert('Handler for .submit() called.');
//$('input[name=PME_sys_canceladd]').submit();
});
});
but doesn't seem to pick up the click event on the button..

I think you should be doing this
$("iframe").contents().find()
instead of just using $().
So maybe this would work:
$("#iframe_manage").load(function () {
$("#iframe_manage").contents().find('input[name=PME_sys_canceladd]').click(function() {
alert('Handler for .submit() called.');
//$('input[name=PME_sys_canceladd]').submit();
});
});
