Question

目前我的导航栏文字是菜单，当点击它时我希望菜单更改为关闭，当菜单关闭时，它应该返回说菜单

以下是我的当前代码 - 点击后它会更改为“关闭”＆＃39;但不会改变：

jQuery(document).ready(function() {

    jQuery(".menu-Trigger").click(function() {

        jQuery(".nav-menu").slideToggle(400, function() { 
             jQuery(this).toggleClass("nav-Expanded").css("display", "");

          });
        $(".menu-Trigger").html("Close");
    });
});

HTML和CSS代码：

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>Arshdeep Soni</title>
        <meta charset="utf-8"/>
        <meta name="viewport" content="width=device-width, inital-scale=1">

我认为你只是错过if表达式来检查你的菜单是否被扩展。不确定你的HTML，但这可能有效：

jQuery(document).ready(function() {

    jQuery(".menu-Trigger").click(function() {

        jQuery(".nav-menu").slideToggle(400, function() { 
             jQuery(this).toggleClass("nav-Expanded").css("display", "");

          });
        if (jQuery(this).hasClass("nav-Expanded"))
            $(".menu-Trigger").html("Close");
        else
            $(".menu-Trigger").html("Menu");
    });
});
