Detect enter in input elements of a certain class

Question

I need to detect when someone hits \"enter\" in text inputs with a specific class.

My jQuery is as follows:

$(\'input.large\').keypress(function (e) {

Thanks David Rodrigues for your explanation. It helped a lot. I had to upgrade my JQuery library and the .live() function stopped to work properly.

You can use it to the following

Select all check box inputs of a form when click on select_all_checkboxes input type checkbox:

jQuery(document).on("click", "#select_all_checkboxes", function(){
    var chk = this.checked;
    $('input[id=selectAll]').each(function(){
        this.checked = chk;
    });
});

Call a function "checkMail" when the user left the field using tab ou clicking of the any field that has a class name "email":

jQuery(document).on("blur", 'input.email', function(event){
    var email = $(this).val();
    if (!checkMail(email)) {
        alert("Invalid email.");
        $(this).focus();
    }
});
