禁用输入提交

I have a form with a textfield inside and I am trying to disable the default behavior when the browser submits the whole form if the user presses Enter while the textfield is selected.

$('#recaptcha_response_field').keydown(function(event) { if (event.keyCode == 13) {
     event.preventDefault();
     event.stopPropagation();
     event.stopImmediatePropagation();
     alert("You Press ENTER key");
     return false;
   } 
});

目前收到“您按 ENTER 键”并且默认行为未被覆盖。

尝试这个：

$(document).on("keypress", 'form', function (e) {
    var code = e.keyCode || e.which;
    if (code == 13) {
        e.preventDefault();
        return false;
    }
});

这将阻止表单提交keypress
