I ran into this same problem today and wrote up this quick plugin that
accepts a boolean or function:
$.fn.extend({
showIf: function(fn)
{
var result;
switch (typeof fn) {
case 'function':
result = fn.call(this);
break;
default:
result = fn;
}
if (result) {
$(this.show());
} else {
$(this.hide());
}
return $(this);
}
});
Usage example:
// Show all LI's based on value of condition
var condition = true;
$('ul.tabs li').showIf(condition);
// Show all LI's that contain exactly 3 anchors
$('ul.tabs li').showIf(function()
{
return ($(this).find('a').length == 3);
});
I hope this helps :)
