Menu
Suppose I have 2 links in my page and I want a hidden div to appear at the position the mouse is located (mouse x,y) at on the page when either of links is clicked. Also, I'd like to pass in a value to set the title for the div (see divTitle id).
How can I accomplish this using jQuery?
Hidden Div:
<div class="boxFAQ" id="questionMarkId">
<span id="divTitle"></span>
SHOW ME!
</div>

To show and hide div on mouse click using jQuery, use the toggle() method. On mouse click, the div is visible and on again clicking the div, it hides.
The document. getElementById will select the div with given id. The style. display = "none" will make it disappear when clicked on div.
To display or hide a <div> by a <button> click, you can add the onclick event listener to the <button> element. The onclick listener for the button will have a function that will change the display attribute of the <div> from the default value (which is block ) to none .
jQuery toggle() MethodThe toggle() method toggles between hide() and show() for the selected elements. This method checks the selected elements for visibility. show() is run if an element is hidden. hide() is run if an element is visible - This creates a toggle effect.
The below code will give you idea about showing the div. Proceed with your requirements and then hide it accordingly or display message as you need
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
$('.alink').click(function(e){
$('#questionMarkId').hide();
$('#questionMarkId').css({'top':e.pageY-50,'left':e.pageX, 'position':'absolute', 'border':'1px solid black', 'padding':'5px'});
$('#questionMarkId').show();
});
});
</script>
</head>
<body>
<div class="boxFAQ" id="questionMarkId" style="display: none;">
<span id="divTitle"></span>
SHOW ME!
</div>
<br /><br /><br /><br />
<a href="#" class="alink">Link 1</a>
<a href="#" class="alink">Link 2</a>
</body>
</html>
UPDATED
create a function which will be invoked on clicking of the link. To this function pass your message (any number of parameter)
So your link will look like this
<a href="#" class="alink" onclick="showTitle('This is the title')">Link 1</a>
<a href="#" class="alink" onclick="showTitle('This is another title')">Link 2</a>
Function will look like this
function showTitle(message)
{
$('#questionMarkId').hide();
$('#questionMarkId').css({'top':e.pageY-50,'left':e.pageX, 'position':'absolute', 'border':'1px solid black', 'padding':'5px'});
$('#questionMarkId').show();
$('#divTitle').html(message);
}
UPDATED
Functions with event parameter
function showTitle(message, evt)
{
var e = e || evt || window.event;
// ... rest of the code
}
With the context you provided, here's a help:
$('#questionMarkId').hide();
$('a').on('click', function(e) {
e.preventDefault();
$('#questionMarkId').css( 'position', 'absolute' );
$('#questionMarkId').css( 'top', e.pageY );
$('#questionMarkId').css( 'left', e.pageX );
$('#questionMarkId').show();
});

To get ie to find the mouse coordinates, I had to add the following to the function. I'm surprised there isn't a more "Jquery" way to solve this. Thanks again for all your help!
var posx;
var posy;
if (typeof e.pageY === "undefined")
{ //will e work here?
posx = window.event.clientX + document.body.scrollLeft
+ document.documentElement.scrollLeft;
posy = window.event.clientY + document.body.scrollTop
+ document.documentElement.scrollTop;
alert("was undefined!");
}
else{
posx = e.pageX;
posy = e.pageY;
alert("was NOT undefined!");
}
alert("posy:" + posy);
alert("posX:" + posx);
