tooltip displaying at random position - javascript

I have a requirement where i have multiple tables in a page and when i mouse over on one column it has to show tooltip at the top position with some data in it. Issue is tooltip is showing randomly. Thanks.

first off, make sure you're correctly terminating your spans (you're missing the ending bracket).
change this:
a.tooltip:hover span {
position: fixed;
to this
a.tooltip:hover span {
position: absolute;

Vertically aligning animated divs

I have three buttons that set different output text when clicked and I'm trying to use W3.CSS animations to "slide" the text in and out. I almost have it working using two separate divs but cannot get them to align correctly under the buttons; the div for every other button click displays lower than the previous one.
I've tried float, vertical-align: top, display: inline-block, and a few other things so far but either used them incorrectly or something else (a conflicting parent div style, maybe?) is causing problems.
Image with a button's output displaying right under the buttons (as it should)
Image with the next button's output displaying lower than the first
I trimmed code that wasn't relevant while also leaving what was necessary to show the div structure for this particular section.
HTML: The divs with IDs old_output and new_output are what I'm trying to align below the buttons
CSS: div.button_output_container and div.button_output are used for the output divs and their container
JS: Handles button clicks, decides which animation should be used, and sets the output text (aside from demonstrating the issue I think it's mostly irrelevant)
JSFiddle link
I am not sure I totally understand your alignment requirement,
but if you just want your divs to render on the same height, you could opt for position:absolute like so:
div.button_output_container {
position: relative;
}
div.button_output {
margin: 16px 24px;
width: 450px;
position: absolute;
}

CSS images placement in table with absolute position

I am trying to cycle through two sets of images using some Javascript. In order for each image to replace the old one as it cycles, I need to use css and set the position to absolute.
I'd like to align the image sets in a html table. If I don't specify positions within the css, the two image sets are on top of each other. If I do, they ignore the table, which I think is caused by the absolute positioning.
Rather than display a lot of code here, I will share a JSFiddle: http://jsfiddle.net/n342aadc/3/
Add:
td {
position: relative;
width: 50px;
}
.container img.
.container1 img {
position: absolute;
}
fiddle
I think you need to specify a width for td otherwise it seems to collapse.

How to generate a textbox on top of a mapbox map?

I am rather new to JavaScript, but I have this mapbox map that I hope to add a dynamic textbox on top of. Right now, I have a window.setintervalcommand running that adds new markers to the map every half second or so. What I want to do is add a changing textbox that displays a date, which changes with every window time interval.
Could anyone help me with adding this textbox in the corner or something so that it displays a changing date (starting from 1/1/16 on) on top of the mapbox box?
You could just do something like this:
<div class="container">
<div class="element-with-timer"></div>
<div class="element-with-map"></div>
</div>
<style>
.container {
position: relative;
}
.element-with-timer {
position: absolute;
z-index: 5;
}
</style>
Within the .element-with-timer css styles, would would then place the element where you want on the page by changing "left" or "top" values.
If you want to keep the timer in the same position, regardless of scroll position, change position: absolute to position: fixed

Filmstrip Style Image Gallery

I am trying to figure out how to create an image gallery like the one illustrated below so I can place it onto my website. I am wondering if anyone can point me in the right direction for a tutorial? I have found a lot of nice galleries that will display my images, but none of them displays the images like in the filmstrip style I am after.
Requirements of gallery:
When clicking on the arrows, the gallery strip will either shift
left/right by one picture
Hovering over the image will darken the image, and display some
caption about the image
I just answered a question where someone was using carouFredSel. This jQuery plugin looks like it would work pretty well, though I do not think it has the built-in hover effect. To be honest though, that is the easier part.
The trick is to make the width slightly larger than the images to show, which leads to the partial images on each side.
Here is a jsfiddle to illustrate.
UPDATE:
The OP asked if the page nav links could be repositioned. I modified the jsfiddle to work this way. The additions were as follows:
.list_carousel {
position: relative;
}
#prev2 {
position: absolute;
top: 35px;
left: 0;
}
#next2 {
position: absolute;
top: 35px;
right: 0;
}
If you have a relatively positioned container element, you can absolutely position child elements. I added relative positioning to the list_carousel container, then I could absolutely position the nav arrows within the container. Change the top value to position vertically, and left/right to position horizontally.
I also removed the pager all together, as it was not a requirement based on the original example. If you change the page arrows to images it is pretty much what you want.
MORE UPDATES
I decided to take it one step further and make the hover effect work more like the example. See the new jsfiddle. The changes are:
Added span wrappers around all text within list items
Added $(".list_carousel li span").hide(); to hide all the spans
Modified hover event to toggle spans
I also added some CSS to position the span text:
.list_carousel li {
position: relative;
}
.list_carousel li span {
position: absolute;
bottom: 0;
display: block;
text-align: center;
width: 100%;
}
FINAL UPDATE (I PROMISE!)
I decided to go all in and add the transparency layer too: jsfiddle
Hover modifications:
$(this).prepend($("<div class='hover-transparency'></div>")); and $(this).find("div:first").remove(); to add/remove transparency layer on hover in/out.
CSS modifications:
.hover-transparency {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background-color: rgba(0, 0, 0, 0.60);
}
These style the transparency layer. Change to suit your taste.
Something like jCarousel should do the trick. Once you have the carousel functionality in place, you can add in the hover affect via CSS and a span that contains the caption.
I was just looking at ContentFlow Plugin which is JavaScript based.
They include a separate library of additional plugin you can use that takes care of your Slideshow requirements, in particularity this one HERE. When you use the mousewheel over the 3 images, it scrolls by 1. That said, you can mod the plugin to do the same when the arrow buttons are clicked.
Sample plugin markup looks like:
{
shownItems: 3, //number of visible items
showCaption: true // show item caption
width: 100, // relative item width
height: 100, // relative item height
space: 0.4 // relative item spacing
}
To address that the captions should be visible only on mouse hover, I would set showCaption to always be true along with using a jQuery .hover(); Event Listener that will use .show(); and .hide(); on the caption Class Name .caption when required. Also, using jQuery to set the opacity can be done within the .hover(); event too.
The latest version of ContentFlow v1.0.2 supports multiple instances on the same webpage if that's ever required.

Implementing a hover info box

I have a calendar, and when the user hovers over a cell, a large-ish info box appears with details for that date. I am having some trouble though making the info box disappear when the user moves away.
I basically want it so that when the mouse cursor moves out of the calendar cell which is hidden by the info box it will disappear. But I'm having trouble with this because mouseenter and mouseleave get messed up by having the info box as the top element.
So I tried to get around this by using "placeholder" divs that are transparent, have the same shape and location as the calendar cell beneath it, and have a z-index of 1000 so they are above the info box. I then apply the mouseenter and mouseleave events to these divs instead.
There's two problems with this though. One, I have now messed up my HTML semantically. The divs have no purpose but to get around what seems to be a limitation. And secondly, they mess up my jQuery UI selection (I've applied it to the calendar cells - a click no longer selects a cell).
Is there a clean way to handle displaying an info box? There will be no user interaction with the info box -- it's just to display information.
EDIT: Here is some code:
<li>
<div class="day-content">
</div>
<div class="day-content-placeholder">
</div>
</li>
and CSS
li
{ position: absolute; width: 15%; height: 20%; top: ... left: ... }
.day-content
{ position: absolute; width: 100%; height: 100%; }
.day-content-placeholder
{ position: absolute; width: 100%; height: 100%; z-index: 1000; }
.popup
{ position: absolute; width: 300%; height: 300%; left: -150%; top: -150%; z-index: 500; }
and Javascript
var popup;
$('.week-content-placeholder')
.mouseenter(function()
{
popup = $('<div class="popup">'+a_lot_of_text+'</div>').insertAfter(this);
})
.mouseleave(function()
{
popup.remove();
});
That's not the exact code, but you get the idea. This works okay, but like I said, since .week-content-placeholder is above .week-content, the selection capability with jQuery UI doesn't work properly on .week-content.
You could modify your solution with the transparent "placeholder" divs in the following way:
Have the "placeholder" dive underneath the "calendar cell", using {zIndex: -1}.
When you enter a calendar cell, unhide the large "content" div and set {zIndex: 1000} on the "placeholder" div to bring it to the top.
Have a "mouseout" event on the placeholder div that will hide the "content" div and set {zIndex: -1} for the the "placeholder" cell.
Rather than create the "placeholder" cells in the HTML, you could create one in the javascript and move it to the postion of each "calendar" cell as you "mouseIn" it. You could also duplicate any "click" events on the "calendar cell" onto this one as well.
Let me know if this works.
The trick here is to make the info box a child of the cell:
<div id='box'>
Normal content
<div id='inner'>
This big box obscures everything in the cell!
</div>
</div>
The inner box is hidden until the hover occurs. Notice how with CSS we can make the box bigger than the cell itself with negative margins.
#box
{
width:100px;
height:100px;
margin:100px;
border:solid 2px darkblue;
position:relative;
}
#box #inner
{
display:none;
position:absolute;
background-color:#eeee00;
top:-10px;
left:-10px;
width:120px;
height:120px;
}
And you can use normal jquery hover because the hover covers box the box and it's child:
$('#box').hover(function(){
$('#inner').show();
},function(){
$('#inner').hide();
});
Here's it running:
http://jsfiddle.net/RbqCT/
You can create the info box dynamically as you do in your code.
Here's 15 different plugins that let you do this with jquery:
http://www.webdesignbooth.com/15-jquery-plugins-to-create-an-user-friendly-tooltip/
You could track mousemouse and use the offsetLeft + width and offsetTop + height of your hover trigger against the event.pageX and event.pageY to compare.
If you make this work as you described a tiny mouse movement that remains within the calendar cell (which is not even visible) leaves the popup in place, but a slightly larger movement that exits the cell makes the popup disappear.
The user sees only movement within the popup itself — small movement within the popup leaves it in place; large movement makes it go away.
I suggest triggering the disappearance of the popup on exiting the popup div itself. Any movement that remains within the "tip" panel leaves it up. I think that (1) this is better usability and (2) it avoids the whole problem with the obscured calendar cell event handling.
You could do that by adding a .mouseleave() handler to the div when you create it.
