推荐答案

jQuery只是一个在Web浏览器中增强DOM功能的库;底层语言是JavaScript，正如您可能希望从编程语言中获得的那样，它具有执行条件逻辑的能力，即

jQuery is just a library which enhances the capabilities of the DOM within a web browser; the underlying language is JavaScript, which has, as you might hope to expect from a programming language, the ability to perform conditional logic, i.e.

if( condition ) {
    // do something
}

测试两个条件也很简单：

Testing two conditions is straightforward, too:

if( A && B ) {
    // do something
}

亲爱的上帝，我希望这不是一个巨魔......
