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) {

You can use live (.on()) events in document with keydown (I think this is better). It'll allow you detect keydown in current and future elements that matches with a selector.

HTML:

Personal Name



Email

JS (jQuery 1.7+):

Note: .which, .code, .charCode and .keyCode is now deprecated. Use the following new solution:

jQuery(document).on('keydown', 'input.large', function(ev) {
    if(ev.key === 'Enter') {
        // Will change backgroundColor to blue as example
        this.style.backgroundColor = '#EFF';

        // Avoid form submit
        return false;
    }
});
