I'm having a few problems with a hide/show function in jQuery that I can't seem to figure out. I have a if/else statement which is checking against a data attribute in my HTML, it's then hiding/showing the element based on the results of it. I've been able to log the entire function and it's triggering the correct statements when they are supposed to, but the problem I'm having is getting the content to reappear again after it was hidden. It hides properly, but never comes back. Here is the code:
var bar = $("#alert");
if (!supressed) {
bar.animate({height:0});
bar.parent().animate({height:0}, function() {
$(this).hide()
});
}
if (supressed) {
console.log("Supressing");
bar.replaceWith(newBar);
bar.parent().animate({height: "45px"}, function() {
$(this).show()
});
bar.animate({height: "45px"});
}
The problem is occuring where the console.log("Supressing"); statement is. It logs it to the console so I know it's working, but for some reason the bar is not appearing at all.
If I do an inspect element I can still see that the parent of #alert still has style="height: 0px; display: none;" on it.
Where am I going wrong?
The problem is you're using the replaceWith function (first line after the else statement). Then you call bar.parent() after the element has been removed from the DOM.
Maybe you meant to say
newBar.parent().animate({height: "45px"}, function() {
$(this).show()
});

Issue:
$(document).on('click', function (e) {
if($(e.target).closest('.treatments, .info').length == 0){
if($(".treatments, .info").is(":visible")) {
$(".treatments, .info").fadeOut("fast")
}
}
});
So, everything here is functioning how I want it to except when you click on the dropdown items (.treatments & .info), the submenu immediately disappears. This is due to the code above which is meant to tell the submenu to disappear when you've clicked anywhere in the document EXCEPT on the elements themselves, and ONLY if the elements are visible.
I'm going to try changing the order of the conditions of the function to see if I can get anywhere with that, but I'm running out of ideas with this one.
There is no $.slideOut() method. You're getting an error on the console. Change it to a $.slideUp and it works fine. http://codepen.io/anon/pen/yeEVjq
// $(".info").slidePut("fast");
$(".info").slideUp("fast");
Always check your console!
I'm new to JQuery and can't for the life of me figure out why this isn't behaving properly. As the content in my "content" div changes, I want it to fade in and out. I created a generic "load" function to do this:
function loadPage(page, callback) {
if(current_doc != page) {
current_doc = page;
$("#content").fadeOut(400, function() {
$("#content").load(current_doc, function() {
$("#content").hide().fadeIn(400, function() {
if(typeof(callback) == 'function'){ callback(); }
});
});
});
}
}
Is there some sort of glaring mistake that I'm missing?
Thanks.
P.S. - This code works fine in Firefox.
One thing to check in IE, in Internet Options > Advanced, under Multimedia should be a checkbox that says "play animations in webpages". Ensure that is checked.
While I'm not entirely sure why, placing the content div inside another div and fading that instead seems to have done the trick. I would think that that would have been giving me issues only if "content" itself were being deleted, but that isn't the case from my code. Oh well.
I've seen answers on here on how to do this, but I just can't get it to work. Maybe another set of eyes will help. I'm trying to get the scrollbar to appear in a div that popups when an image is clicked. Here's the code for that:
('modalcs' is the name of the div that pops up)
And the function:
function update_scroll(theID)
{
document.getElementById(theID).style.display = 'block';
$(".scrollable").mCustomScrollbar("update");
}
In my $(document).ready(function() I have:
$(".scrollable").mCustomScrollbar({
theme:"dark-thick",
scrollButtons:{
enable:true,
advanced:{
updateOnBrowserResize:true,
updateOnContentResize:true
}
}
});
and I understand that on page load since the hidden div isn't seen, the scrollbar is unable to see its content.
TIA for any help!
The problem is that the "update" command does not operate on a collection, so if $(".scrollable") returns more than one element, it will update only the first one. Use $.each
$(".scrollable").each(function(){
$(this).mCustomScrollbar("update");
});
On the other hand, since you are operating on 1 element, you can just change your function:
function update_scroll(theID)
{
$('#' + theID).show().mCustomScrollbar("update");
}
I have this code that makes a box with information follow the mouse. It's really simple, just checks the custom attribute "description" in the div that you hover over and puts that in the box. However, I want to make it so if that div also has a certain CSS class, then it would put other information in the box, in addition to the other code still working.
$(document).ready(function(){
$(".hover").mousemove(function(e){
if ("div").hasclass("item"){
alert("div hasclass item");
} else {
var description = $(this).attr("description");
$("#hoverdiv").text(description).show();
$("#hoverdiv").css("top", e.clientY+10).css("left", e.clientX+5);
}
}).mouseout(function(){
$("#hoverdiv").hide();
});
});
that's the code I have now. None of the hovers in my page work at all. This is the code that works. It's identical in every way, except no if statement.
$(document).ready(function(){
$(".hover").mousemove(function(e){
var description = $(this).attr("description");
$("#hoverdiv").text(description).show();
$("#hoverdiv").css("top", e.clientY+10).css("left", e.clientX+5);
}).mouseout(function(){
$("#hoverdiv").hide();
});
});
I've tried time and time again to get this to work, and through my testing, it would seem that simply adding an if statement breaks the entire thing. I have absolutely no idea how to proceed or how to fix it.
The culrpit..
if ("div")
Maybe you were trying
if($("div").something()){
}
if ("div").hasclass("item") {
Should be:
if ( $("div").hasClass("item") ) {
For some more you can also test:
if ( $("div").is(".item") ) {

Multiple Dialog
I was able to solve the issue but now problem is that it removes the div so when I access that Div it give error. It gives error because when I open dialog it works fine after removing on close it gives e.rror
I don't want to removed jQuery('#divPopup') If there is only one div present. If multiple jQuery('#divPopup') are there remove() should be working fine.
jQuery('.register_button_class').live('click',function () {
var iFrameobj = createIframe('',iframeUrl);
jQuery('#divPopup').html(iFrameobj);
createDialogWithClose(url,'#bodyId');
return false;
});
Dummy Div for Dialog Popup, This get removed, when Click on Close Jquery Ui Popup.
So when I say
jQuery('#divPopup').html(iFrameobj);
It gives error.
<div id="divPopup"></div>
I'm assuming that your function:
createDialogWithClose(url, '#bodyId');
removes the div id="divPopup" each from the DOM when you close it.
I would suggest not initially including that div in your markup and change your function to create the div and append it to the DOM when it runs. Then remove like you're already doing.
jQuery('.register_button_class').live('click',function () {
var iFrameobj = createIframe('',iframeUrl);
jQuery("body").append("<div id='divPopup' />").html(iFrameobj);
createDialogWithClose(url,'#bodyId');
return false;
});
It's hard to tell what other issues you may be running into with this bit of code that you posted, however, jQuery("body").append("<div id='divPopup' />").html(iFrameobj); will create the divPopup each time the function runs. So, when you close it and it gets removed it will just get created again the next time that button is clicked.
EDIT: How to check if a Div exists -
if ($("#divPopup").length > 0){
// do something here
}
I solved like this
var length = jQuery('#divPopup').length;
if(length>1)
{
jQuery('#divPopup').dialog('destroy').remove();
}else
{
jQuery('#divPopup').dialog('destroy');
}
