The reason why I don't want anyone adding more than 250 fields is
because if they were to go over that amount, 251 and so on would not
get entered into the mysql db. I know some people will probablly be
thinking, why would I have such a large table? Well I don't really
want to go into that and that would be going off topic, lol.
Well here's how I have the code:
--- code ---
(function($) {
// Add repeat method to String object
String.prototype.repeat = function(n){
return new Array(n + 1).join(this);
};
// Add leading_zeros method to jQuery
$.leading_zeros = function(n, total_digits){
n = n.toString();
return '0'.repeat(total_digits - n.length) + n;
};
})(jQuery);
$(document).ready(function(){
// initialize the counter
var counter = 10;
$('#fields-button').click(function(){
// increment and pad the counter
var padded_counter = $.leading_zeros(++counter, 3);
// create the new field
var extrafield = '<tr><td>List Item #' +
padded_counter + '</td><td>';
extrafield += '<input type="text" name="x_c' +
padded_counter + '"' ;
extrafield += ' id="x_c' + padded_counter + '"' ;
extrafield += ' title="" size="30" maxlength="255"' ;
extrafield += ' value="" </td></tr>';
// add the new field to the table
$('#fields').append(extrafield);
});
});
--- code ---
Checking the value after each increment sounds like a good approach.
> Two possibilities come to mind. Create an object that checks
> itself as it changes or just check the value after each increment.
> I tend to lean toward objects, but they tend to take more time to
> write. Knowing the context of the limitation (or cap) would help a
> lot.
