Why is jQuery append duplicating my content?
Question
When i use appendBox function below, first time it works fine and the same with removeBox, but second time it doesn't work properly: it duplicates my content.
What is wrong?
function appendBox( id )
{
$("#listContainer").append("<div id=\"appendbox-"+ id +"\"><a href=\"javascript:removeBox("+ id +");\">remove</a></div>");
$("#addBox-"+ id ).slideUp();
}
function removeBox( id )
{
$("#listMyBoxs").append("<div id=\"addBox-"+ id +"\"><a href=\"javascript:appendBox("+ id +");\">tilføj</a></div>");
$("#appendbox-"+ id ).slideUp();
}
this its my html when i try this test
<div style="height: 200px; border: 1px solid black;">
<div id="listContainer"></div>
<div id="listMyBoxs">
<div id="addBox-1">
<a href="javascript:appendBox( 1 );">tilføj</a>
</div>
</div>
</div>
Solution
I would change the way you're doing it. A more typical solution would like this:
<div id="outer">
<div id="listContainer"></div>
<div id="listMyBoxes">
<a href="#">tilføj</a>
</div>
</div>
with:
#outer { height: 200px; border: 1px solid black; }
#outer a { display: block; }
and
$(function() {
$("#listContainer a").live("click", function() {
$(this).slideUp(function() {
$(this).appendTo("#listMyBoxes").text("remove").slideDown();
});
return false;
});
$("#listMyBoxes a").live("click", function() {
$(this).slideUp(function() {
$(this).appendTo("#listContainer").text("tilføj").slideDown();
});
return false;
});
});
Adjust as required. If you need more complex content than a simple link then you can enclose that in a div and adjust as necessary. The principles are all the same.
OTHER TIPS
If you want to move an existing element, try:
$("#appendbox-"+ id ).appendTo('#listMyBoxs');
Using $("<div></div>")
or .append("<div></div>")
creates a new element.
The same issue here, I used to append content to page using javascript and jQuery, it works fine at Chrome, but when trying it with Firefox it duplicates the appended content.
I use this code to append content to a div:
function PlayGames() {
$(".gameActions, #flash-game").show();
$(".TheGame").show().append("<object id='flash-game' type='application/x-shockwave-flash' height='100%' width='100%' frameborder='0' scrolling='no' data='URL'>");
}
Don't know why this happens only in Firefox and IE sometimes.
