Unbind a div and then bind it later
Question
$('.tab').click(function() {
$(this).unbind("click");
var classy = $(this).attr("class").split(" ").splice(-1);
var ihtml = $('.content.'+classy).html();
$('#holder').html(ihtml);
$('.tab').removeClass('highlight');
$(this).addClass('highlight');
$(this).unbind("click");
});
So in this code I have basically, a tabbed interface. When I click the tabs again the information in the #holder disappears. So what I would like to do is unbind clicks whenever the user clicks on the tab, and then bind it when they switch tabs. How can I integrate this into my code?
Thanks.
Solution
You could try adding a class 'active' when a tab is clicked (generally good practice), then use jQuery's live()
to do some fancy stuff...
$('.tab:not(.active)').live('click', function () {
$('.tab').removeClass('active');
$(this).addClass('active');
...
});
I guess that does the trick.
OTHER TIPS
also, you can try to use this kind of syntax (which should be faster and more memory&cpu friendly):
$('.tab').click(function(){
var t=$(this);
if(t.hasClass('active')){return false;}
$('.active').removeClass('active');
t.addClass('active');
/* do some stuff here */
return false;
});
Or even better, to avoid repeating yourself:
$('.tab').click(function(){
var t=$(this);
if(!t.hasClass('active')){
$('.active').removeClass('active');
t.addClass('active');
/* do some stuff here */
}
return false;
});
Why is this faster & cpu friendly? Because you bind this only once. When you use live
bind method, the browser will listen for any change in the DOM.
