How can I with js or jQuery change input text value with js or jQuery before submit if the input value is null ?
Thanks for help.
With jQuery, you can bind a callback to the submit event with the .submit() method.
$(form).submit(function(){
// Let's find the input to check
var $input = $(this).find(input[name=whatever]);
if (!$input.val()) {
// Value is falsey (i.e. null), lets set a new one
$input.val(whatever you want);
}
});
Notice: To ensure that all the elements can be found it should be placed in a domready function.
