if or switch? and how to?

in Getting Started • 11 years ago

I have a function where I count all div fieldcontain with class="count" and append a number according to the result of the count. I would also like to check if there is only one div fieldcontain with class="count" and if so - not append the number of the count. I haven't succeded in finding the correct if statement for this. Or maybe a switch?

$('#edit').live("pageinit", function(){
$(this).find('.fieldcontain').each(function(index){
$(this).append('<div class="count">' + (index + 1) + '</div>');
});
});

You can use length to determine how many elements were returned in the set. So, something like this might help you:

$('#edit').live("pageinit", function(){
if ($(this).find('.fieldcontain').length > 1) {
$(this).find('.fieldcontain').each(function(index){
$(this).append('<div class="count">' + (index + 1) + '</div>');
});
}
});
