Add http:// to text input if there is none

[KarimCossutti]

Hello i have a text input that need an url as value (complete of http://)
and i want that if the user don’t writes it himself if gets added automatically…

I came up with this code (jQuery)

$('.textin').keypress(function(e) {

if(e.keyCode == 13) {

var ini = $(this).val().substring(0,3);

if (ini === 'http'){

$.noop()

}

else {

cur_val = $(this).val(); // grab what's in the field

// do stuff with cur_val so that it's what you want

$(this).val('http://' + cur_val);

}



}

});

Somehow the function gets executed even if ini is = to http any help would be appreciated, thanks

The problem is that the substring is only getting the first three letters “htt” and it’s being compared to “http” – here is a demo.

Also there is no need for the “$.noop()” function:

$('.textin').keypress(function(e) {

if (e.keyCode == 13) {

var ini = $(this).val().substring(0, 4);

if (ini !== 'http') {

cur_val = $(this).val(); // grab what's in the field

// do stuff with cur_val so that it's what you want

$(this).val('http://' + cur_val);

}

}

});
