如何防止空格粘贴到输入字段中?

How to prevent spaces from being pasted into an input field?

例如:我有两个不同的input字段，分别用于名字和姓氏.不过，我已经通过使用简单的jQuery禁止将空格 typeing 输入到输入字段中，但是，似乎如果我将"Tom Riddle"复制并粘贴到任一输入字段中，则""Tom"和"Riddle"也将粘贴到输入字段中.
由于一个人的名字或一个人的名字将不包含任何空格，因此需要禁用.

这是jQuery，用于禁止输入 的空格:-

For example: I have two different input fields for first name and last name. I have disabled spaces from being typed into the input fields by using a simple jQuery, nevertheless, it seems that if I copied and pasted 'Tom Riddle' into either one of the input fields, the space between 'Tom' and 'Riddle' gets pasted into the input field as well.
edit: As a first name of a person or a last name of a person will not contain any spaces, I need to disable.

This is the jQuery which I use for disabling spaces from being typed :-

$(document).ready(function() {
    $('.no_space').keypress(function(e) {
        if(e.which === 32) {
            return false;
        }
    });
});

推荐答案

绑定

Bind the input event and replace the presence of spaces. For modern browsers, this covers both typing and pasting on an input field.

$('.no_space').on("input", function () {
    $(this).val($(this).val().replace(/ /g, ""));
});

请参见演示.
