In the following example, the alert shows, but the #message is blank.
If I comment out the .insertAfter line then the #message is displayed correctly.
Why doesn't the .insertAfter work in this example?
Firebug just steps right over it.
javascript:
google.load("jquery", "1.3.2");
//run when page is loaded
google.setOnLoadCallback(function() {
$('.languageChooser select').bind('click', function() {
var numberOfItems = $('.languageChooser select option:selected').length;
$('#message').hide().html("You have selected " + numberOfItems + " " + smartPlural('language',numberOfItems) + ".").fadeIn('slow');
if(numberOfItems == 1) {
$('#message').insertAfter('<div>Use the CTRL and SHIFT keys to select multiple items.</div>');
alert('here');
}
});
function smartPlural(itemName, numberOfItems) {
if(numberOfItems == 1) {
return itemName;
} else {
return itemName + 's';
}
}
});

insertAfter works only with elements already existing on the DOM, give a look to the documentation:
The elements must already be inserted into the document (you can't insert an element after another if it's not in the page).
Are you maybe looking for append or appendTo?

In jQuery we use $(element).after([html]) and not $(element).insertAfter([html]).
Just change your code to this and it should work.
google.load("jquery", "1.3.2");
google.setOnLoadCallback(function() {
$('.languageChooser select').bind('click', function() {
var numberOfItems = $('.languageChooser select option:selected').length;
$('#message').hide().html("You have selected " + numberOfItems + " " + smartPlural('language',numberOfItems) + ".").fadeIn('slow');
if(numberOfItems == 1) {
//$('#message').insertAfter('Use the CTRL and SHIFT keys to select multiple items.');
$('#message').after('Use the CTRL and SHIFT keys to select multiple items.');
alert('here');
}
});
function smartPlural(itemName, numberOfItems) {
if(numberOfItems == 1) {
return itemName;
} else {
return itemName + 's';
}
}
});
