I'm attempting to use Jquery and Javascript so when a client mouseovers a generic icon used on a PageGridView it will display the thumbnail image slightly offset from the icon.
I'm borrowing the code I found on Techrepublic.
CSS Being used:
<style type="text/css">
#Fullimg{position:absolute;display:none;z-index:-1}
#preview{
position:absolute;
border:3px solid #ccc;
background:#333;
padding:5px;
display:none;
color:#fff;
box-shadow: 4px 4px 3px rgba(103, 115, 130, 1);
}
pre{
display:block;
font-family:Tahoma, Geneva, sans-serif;
font-weight:normal;
padding:7px;
border:3px solid #bae2f0;
background:#e3f4f9;
margin:.5em 0;
overflow:auto;
width:800px;
}
</style>
Javascript:
<script type="text/javascript" language="javascript">
// Kick off the jQuery with the document ready function on page load
$(document).ready(function(){
imagePreview();
});
// Configuration of the x and y offsets
this.imagePreview = function(){
xOffset = -20;
yOffset = 40;
$("a.preview").hover(function(e){
this.t = this.title;
this.title = "";
var c = (this.t != "") ? "<br/>" + this.t : "";
$("body").append("<p id='preview'><img src='"+ this.link +"' alt='Image preview' />"+ c +"</p>");
$("#preview")
.css("top",(e.pageY - xOffset) + "px")
.css("left",(e.pageX + yOffset) + "px");
},
function(){
this.title = this.t;
$("#preview").remove();
});
$("a.preview").mousemove(function(e){
$("#preview")
.css("top",(e.pageY - xOffset) + "px")
.css("left",(e.pageX + yOffset) + "px");
});
};
</script>
Icon:
<asp:Image ID="imgThumbnail" runat="server" ImageURL="~/Images/imgHover.png" ImageAlign="AbsMiddle" ClientIDMode="Static" CssClass="preview" link='<%# String.Format("~/ConvertImage.ashx?FleetID=" + m_oUserInfo.CurrentFleetID + "&VehicleID={0}&picID={1}&picType=PictureThumb&extention={2}", Eval("VehicleID"), Eval("StoredPictureID"), Eval("PictureExtension"))%>'/>
The code does absolutely nothing oddly, despite even trying to make it work in a fiddle. I've been beating my head against the wall on this for almost a week and the boss is starting to get annoyed that I can't get it working.
Any help or a more code efficient means of doing this would be greatly appreciated.
I corrected some basic part in the code. Here is the link:http://fiddle.jshell.net/bpVUk/2/
You can modify now as per your needs.
Code:
// Kick off the jQuery with the document ready function on page load
$(document).ready(function () {
var xOffset = -20;
var yOffset = 40;
$('.preview').on('mouseover', function (e) {
var img = $(this);
img.t = img.title;
img.title = "";
var c = (img.t != "") ? "<br/>" + img.t : "";
$("body").append("<p id='preview'><img src='" + img.attr('link') + "' alt='Image preview' />" + c + "</p>");
$("#preview").css({
"top": (e.pageY - xOffset) + "px",
"left": (e.pageX + yOffset) + "px",
'display': 'block',
});
});
$('.preview').on('mouseleave', function (e) {
$('#preview').remove();
})
});

I need some help :)
Working on a portfolio website with an image preview when you hover over a portfolio title. Whenever I hover over de last few titles at the bottom of the page, there are some ugly glitches/bounces: the image escapes the bounds of the webpage. Is there a way to make it direction aware, so that when you hover over the last few titles the image preview shows up above the title instead of below?
The HTML:
<ul class="project-list">
<li>
Title Here
</li>
</ul>
The CSS:
#preview {
position: absolute;
display: none;
max-width: 50rem;
height: auto;
}
The JS:
$(document).ready(function(){
imagePreview();
});
// Configuration of the x and y offsets
this.imagePreview = function(){
xOffset = -30;
yOffset = 40;
var imgHeight = 0;
var distFromTop = 0;
var mainImgTop = $(".preview").position();
$(".preview").hover(function(e){
this.t = this.title;
this.title = "";
var c = (this.t != "") ? "<br/>" + this.t : "";
$("body").append("<p id='preview'><img style='display:block;' src='"+ this.rel +"' alt='Image prev' />");
$("#preview")
.css("top",(e.pageY - xOffset) + "px")
.css("left",(e.pageX + yOffset) + "px")
.fadeIn("slow");
},
function(){
this.title = this.t;
$("#preview").remove();
});
$(".preview").mousemove(function(e){
$("#preview")
.css("top",(e.pageY - xOffset) + "px")
.css("left",(e.pageX + yOffset) + "px");
});
};
Here is a JSFiddle: https://jsfiddle.net/spacebot/b7h46cfh/
If you just want to show the image above the last X amount of titles, you can use :nth-last-child(-n+X) (where X is the amount of titles).
Check if the title is one of the last titles and run another animation to show the image above.
//If link is one of the last 3 childs, open above
if($(this).is(':nth-last-child(-n+3)')){
openAbove();
}

I am trying to make the smile.png image to appear in a random position within the specific <div>.
What I have done is to set the variable.style.top= top_position+'px' & variable.style.left = left_position+"px".
However, what I am getting so far are the images the are horizontally aligned and not randomly positioned. How am I able to do that?
var theLeftSide = document.getElementById("leftSide");
var randomY = Math.round(Math.random()) + 'px';
var randomX = Math.round(Math.random()) + 'px';
function generateFaces() {
for (numberOfFaces = 0; numberOfFaces < 5; numberOfFaces++) {
createElement(numberOfFaces);
}
}
number = 0;
function createElement() {
number++;
//creating the image on the leftside
var smiley = document.createElement('img');
smiley.src = "smile.png";
smiley.style.position = "absolute";
smiley.style.left = randomX;
smiley.style.top = randomY;
theLeftSide.appendChild(smiley);
}
#leftSide {
position: absolute;
width: 500px;
height: 500px;
}
#rightSide {
position: absolute;
width: 500px;
height: 500px;
left: 500px;
border-left: 1px solid black;
}
<body id="smileyGuessingGame" onload="generateFaces()">
<h1>Matching Game</h1>
<p>Click on the extra smiling face on the left</p>
<div id="leftSide">
</div>
<div id="rightSide">
</div>
</body>
There are few syntax errors in your code. You can compare your code with the code provided below.
Also note toFixed returns a A string representation of numObj that does not use exponential notation and has exactly digits digits after the decimal place.
Try this:
var theLeftSide = document.getElementById("leftSide"),
top_position = parseInt(Math.random() * ($(document).width() - 500)),
left_position = parseInt(Math.random() * ($(document).width() - 500));
function generateFaces() {
for (var numberOfFaces = 0; numberOfFaces < 5; numberOfFaces++) {
createElement(numberOfFaces);
}
}
var number = 0;
function createElement() {
number++;
//creating the image on the leftside
var smiley = document.createElement('img');
smiley.src = "https://upload.wikimedia.org/wikipedia/commons/thumb/8/8d/Smiley_head_happy.svg/2000px-Smiley_head_happy.svg.png";
smiley.style.position = 'absolute';
smiley.style.top = top_position + "px";
smiley.style.left = left_position + "px";
theLeftSide.appendChild(smiley);
top_position += 20;
left_position += 20;
}
#leftSide {
position: absolute;
width: 500px;
height: 500px;
}
#rightSide {
position: absolute;
width: 500px;
height: 500px;
left: 500px;
border-left: 1px solid black;
}
img {
width: 100px;
height: 100px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<body id="smileyGuessingGame" onload="generateFaces()">
<h1>Matching Game</h1>
<p>Click on the extra smiling face on the left</p>
<div id="leftSide">
</div>
<div id="rightSide">
</div>
</body>
Fiddle here
I'd code this using jQuery and lodash. Here's a jsfiddle:
https://jsfiddle.net/mckinleymedia/3z6wsnyf/2/
The html:
<h1>Matching Game</h1>
<p>Find the unique image</p>
<div class="game"></div>
And the code:
var game = function(options) {
var panes = 2,
game = $('.game'),
height = 500,
width = game.width() / panes - 20,
itemSize = 50,
faces = 5,
guesses = 5,
setupBoard = function() {
game
.empty();
_.times(panes, function(p) {
game
.append(
$('<div>')
.addClass('pane pane' + p)
.css('height', height + 'px')
.css('width', width + 'px')
);
})
},
startGame = function() {
_.times(faces, function(i) {
_.times(panes, function(p) {
$('.pane' + p)
.append(
$('<img>')
.attr('src', 'http://lorempixel.com/200/20' + i)
.addClass('img-' + i)
.css('top', _.random(height - itemSize) + 'px')
.css('left', _.random(width - itemSize) + 'px')
);
})
});
$('.game img').click(function() {
guesses--;
alert('Nope! You\'ve got ' + guesses + ' guesses remaining.');
});
$('.pane' + _.random(panes - 1))
.append(
$('<img>')
.attr('src', 'http://lorempixel.com/200/20'+ (faces + 1))
.addClass('img-t')
.css('top', _.random(height - itemSize) + 'px')
.css('left', _.random(width - itemSize) + 'px')
.click(function() {
alert('You got it! Good job! You just cleared ' + faces + ' images! You\'ve got ' + guesses + ' guesses remaining.');
faces++;
setupBoard();
startGame();
})
);
$('.game img')
.css('height', itemSize + 'px')
.css('width', itemSize + 'px')
.css('-moz-border-radius', itemSize / 2 + 'px')
.css('-webkit-border-radius', itemSize / 2 + 'px')
.css('border-radius', itemSize / 2 + 'px')
.css('-khtml-border-radius', itemSize / 2 + 'px')
};
setupBoard();
startGame();
};
game();
Maybe something like this could work:
function generateRandom(min, max) {
var num = Math.random() * (max - min) + min;
return Math.floor(num);
}
var width,
height,
img;
width = $( '#leftSide' ).width();
height = $( '#leftSide' ).height();
img = $('<img id="smiley">');
img.attr('src', 'http://vignette2.wikia.nocookie.net/robocraft/images/2/26/Smile.png');
img.css('top',generateRandom(0,height));
img.css('left',generateRandom(0,width));
img.appendTo('#leftSide');

I cant get this code to work. It's supposed to be a custom dialog box. When a certain event transpires, the div pops up with an animation like it's moving towards you from a distance. The div has a clickable link that is supposed to trigger the removal of the box when clicked.
It works fine for one iteration, but when I attempt to trigger it again the whole thing falls apart in a horrendous way. The console doesn't issue any warnings or errors, but the browser freezes then crashes.
Any help would be appreciated.

var x = $('<div></div>').prependTo(element);
x.attr("id", "pop_up_div");

Want the code to validate if the popup is actually in the viewport or not.
somethinglike if (screenshotWidth + screenshotX > window.innerWidth) { // do stuff } and then same for height, but that's as far as i know.
thanks.
this.screenshotPreview = function(){
/* CONFIG */
xOffset = 10;
yOffset = 30;
// these 2 variable determine popup's distance from the cursor
// you might want to adjust to get the right result
/* END CONFIG */
$("a.screenshot").hover(function(e){
this.t = this.title;
this.title = "";
var c = (this.t != "") ? "<br/>" + this.t : "";
$("body").append("<p id='screenshot'><img src='"+ this.rel +"' alt='url preview' />"+ c +"</p>");
$("#screenshot")
.css("top",(e.pageY - xOffset) + "px")
.css("left",(e.pageX + yOffset) + "px")
.fadeIn("fast");
},
function(){
this.title = this.t;
$("#screenshot").remove();
});
$("a.screenshot").mousemove(function(e){
$("#screenshot")
.css("top",(e.pageY - xOffset) + "px")
.css("left",(e.pageX + yOffset) + "px");
});
};
// starting the script on page load
$(document).ready(function(){
screenshotPreview();
});
I have a popup system that shows a image when you hover over a link. Instead I need the popup to be activated when you hover over <label>
popup.js
/*
* Url preview script
* powered by jQuery (http://www.jquery.com)

*/
this.screenshotPreview = function(){
/* CONFIG */
xOffset = 130;
yOffset = 60;
// these 2 variable determine popup's distance from the cursor
// you might want to adjust to get the right result
/* END CONFIG */
$("a.screenshot").hover(function(e){
this.t = this.title;
this.title = "";
var c = (this.t != "") ? "<br/>" + this.t : "";
$("body").append("<p id='screenshot'><img src='"+ this.rel +"' alt='image loading...' />"+ c +"</p>");
$("#screenshot")
.css("top",(e.pageY - xOffset) + "px")
.css("left",(e.pageX + yOffset) + "px")
.fadeIn("fast");
},
function(){
this.title = this.t;
$("#screenshot").remove();
});
$("a.screenshot").mousemove(function(e){
$("#screenshot")
.css("top",(e.pageY - xOffset) + "px")
.css("left",(e.pageX + yOffset) + "px");
});
};
// starting the script on page load
$(document).ready(function(){
screenshotPreview();
});
Here is the html that activate the popup
HTML:
<a style="" class="screenshot" rel="images/0.jpg" title="blablabla">blablabla</a>
I tried:
<label for="0" class="screenshot" rel="images/0.jpg" title="blablabla">blablabla</label>and changed to this in the js $("label.screenshot").hover, but I only get image loading and no image..
The issue you are having, is that since this.rel is accessing the dom property rel which is a properly of a a tag but not a property of a label.
Change your code to $(this).attr('rel'), so it will pickup the attribute.
$("body").append("<p id='screenshot'><img src='"+ $(this).attr('rel') ...
