How to place one element exactly to the same visible position, as another?
I have two elements "src" and "dest"
"src" and "dest" are in different DOM-nodes, that can not have the same parent.
I need to place "src" element in the same visible position, as "dest".
"src" element must also have the same sizes, as "dest".
I have following code for case, when "src" and "dest" having the same parent:
src.css("position", "absolute");
src.css("top", dest.offset().top);
src.css("left", dest.offset().left);
src.width(dest.width());
// Show "src" element, instead of "dest". "src" must be in the same visible position, as "dest"
dest.css("opacity", 0);
src.show();
Unfortunately, it does not works. "src" element has displacement to bottom and left, for that i cannot find the reason.
Maybe, i do something wrong ...
How to do it right for two cases ?
- "src" and "dest" having the same grand-parent
- "src" and "dest" does't having the same parent. Maybe grand-grand-grand-parent is the common for both.
Update:
I have arranged a simple HMTL document, that does a simple visual swapping of one element with another:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>MacBlog</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js" charset="utf-8"></script>
<style type="text/css" media="screen">
.dest {
background-color: #0cf;
width: 480px;
height: 320px;
}
.src {
background-color: #09c;
width: 1024px;
height: 768px;
}
</style>
<script type="text/javascript" charset="utf-8">
jQuery(function($){
// Common items, to deal with
var src = $(".src");
var dest = $(".dest");
// Setup
src.hi开发者_如何学运维de();
// Interaction
dest.click(function(){
src.width(dest.width());
src.height(dest.height());
src.offset(dest.offset());
dest.hide();
src.show();
});
});
</script>
</head>
<body>
<div>
<!--On clicking, this element should visually be swapped by ".src" element -->
<div class="dest"><p>dest</p></div>
<div class="src"><p>src</p></div>
</div>
</body>
</html>
It does not work correctly. After "swapping", "src" element has a strange displacement to top-left direction on ~30 pixels.
I use latest version of Safari 5, if i makes sense.
Update 2:
Unfortunately, this also does not works. I updated my example:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>MacBlog</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js" charset="utf-8"></script>
<style type="text/css" media="screen">
div {
margin: 0;
padding: 0;
}
.holder {
position: relative;
top: 40pt;
left: 40pt;
border: black solid thin;
}
.dest {
background-color: #0cf;
width: 480px;
height: 320px;
}
.src {
background-color: #09c;
width: 1024px;
height: 768px;
}
</style>
<script type="text/javascript" charset="utf-8">
jQuery(function($){
// Common items, to deal with
var src = $(".src");
var dest = $(".dest");
// Setup
src.hide();
// Interaction
dest.click(function(){
src.css("position", "absolute");
src.width(dest.width());
src.height(dest.height());
src.offset(dest.offset());
dest.hide();
src.show();
});
});
</script>
</head>
<body>
<div class="holder">
<!--On clicking, this element should visually be swapped by ".src" element -->
<div class="dest"><p>dest</p></div>
<div class="src"><p>src</p></div>
</div>
</body>
</html>
I tested it here:http://jsfiddle.net/YEzWj/1/
Using your second example make your CSS like this:
div {
position:relative;
margin: 0;
padding: 0;
}
.holder {
position: relative;
top: 40pt;
left: 40pt;
border: black solid thin;
}
.dest {
position:absolute;
background-color: #0cf;
width: 480px;
height: 320px;
}
.src {
background-color: #09c;
width: 1024px;
height: 768px;
}
EDIT: After playing around with it some, it did not work in all circumstances. I decided to change the javascript. Note: My example toggles the display of src and dest within the holder, making holder the same size as dest so the border shows outside the dest and src.
jQuery(function($){
// Common items, to deal with
var src = $(".src");
var dest = $(".dest");
var holder=$(".holder");
holder.width(dest.width());
holder.height(dest.height());
// Setup
src.hide();
// Interaction
dest.click(function(){
src.show();
src.css("position", "absolute");
src.width(dest.width());
src.height(dest.height());
src.offset(dest.offset());
dest.hide();
});
src.click(function(){
dest.show();
src.hide();
});
});
EDIT2: Remove the src.click() event if you wish it to NOT go back to the dest on src click.
You need to make the dest
element absolute, otherwise the top
and left
offsets will not apply.
src.css('position', 'absolute'); // ensure position is set to absolute
src.offset(dest.offset());
Also, elements like p
and body will have default stylesheets depending on browser. So try to supply a reset style to make things consistent:
p {
margin: 0;
}
body {
margin: 0;
padding: 0;
}
You can call the offset
function to set the offset and handle different parents correctly, like this:
dest.offset(src.offset());
