当点击 .btn 时，overflow hidden 出现在 body 上是必要的，当再次点击 .btn 时也会消失。请告诉我该怎么做？

$(document).ready(function(){
    $('.btn').click(function(){
        $('.body').css({"overflow: hidden;"});      
        return false;
    });
});
.btn  {
  background: red;
}

为什么不触发 onclick 事件？

let btn = document.querySelectorAll('.btn');

let text = document.querySelector('.text');


btn.onclick = function () {
    text.style.opacity = '20';
  console.log('test');
}
<div class="test-btn">
  <button class="btn">test 1</button>
  <button class="btn">test 2</button>
  <button class="btn">test 3</button>
  <button class="btn">test 4</button>
</div>

您能否解释一下为什么在 querySelectorAll 应用程序期间没有为块设置样式？但是如果您设置了一个 querySelector，那么所需的样式将应用于所需的块。

逻辑是这样的：通过单击按钮，应该会出现一个块。默认情况下，块具有显示：无，通过单击按钮应更改为显示：块

let showMsg = document.querySelectorAll('.msg-1 .msg-2 .msg-3');


function viewMsg() {
    showMsg.style.display = 'block';
}
.msg-1 {
    display: none;
}

.msg-2 {
    display: none;
}

.msg-3 {
    display: none;
}
<div class="chat-ui">
    <div class="chat-items">
        <div class="msg">
            <p>первый этап</p>
            <button value="Click" onmousedown="viewMsg()">далее</button>
        </div>
        <div class="msg msg-1">
            <p>второй этап</p>
            <button value="Click" onmousedown="viewMsg()">далее</button>
        </div>
        <div class="msg msg-2">
            <p>конец</p>
            <button value="Click" onmousedown="viewMsg()">отправить</button>
        </div>
        <div class="msg msg-3">
            <p>полный конец</p>
        </div>

请告诉我如何以 250 像素和 991 像素的分辨率在 2 列中正确布置 flex 元素。以下是它在移动设备上的外观： 在此处输入图像描述

我失败的代码：

.item {
 
    background: red;
    width: 300px;
    height: 300px;
    margin-bottom: 20px;
   margin-right: 10px;
  
}


.items {
  display: flex;
  flex-wrap: wrap;
 
}



@media (min-width: 250px) and (max-width: 991px) {
  .items {
    flex-direction: column;
  }
}
<div class="items">

请告诉我如何制作，以便当您单击一个块时，颜色会更改其值并在您单击另一个块时返回其原始值。我使用活动伪类制作了当前任务，但是当我单击另一个块时，按钮的颜色不会变得相同

代码示例：

.void_history {
  display: flex;
  flex-direction: column;
}

.void_history-item  {
  width: 200px;
  height: 50px;
  background: #248a52;
  border: 1px solid #006633;
  border-radius: 10px;
  display: flex;
  align-items: center;
  justify-content: center;
  margin-top: 20px;
  color: white;
  transition: background 9999999s;
}


.void_history-item:active {
  background: red;
  transition: background 0s;
}
<div class="void_history">
  <div class="void_history-item">Первый выбор</div>
  <div class="void_history-item">Второй выбор</div>
  <div class="void_history-item">Третий выбор</div>
  <div class="void_history-item">Четвёрты выбор</div>

通过单击按钮，应该会出现一个动画，然后应该会出现一个带有消息的块。目前有一个问题是按钮事件不起作用，整个动画和所有带有消息的块都被加载。请告诉我如何解决这个问题

请告诉我如何四舍五入计算的总和，点后只留下一个数字

示例：100 / 0.0030301 = 33002.211148146926
应该是这样的：100 / 0.0030301 = 33002.2

代码示例：

let oneItem = $(".range-price-item-1 p");

let sumItem = $(".range-price-item-3 p");

$('#range-yellow').range({
  min: 100,
  max: 1000,
  start: 100,
  step: 100,
  onChange: function(value) {
    
     $('#display-3').html(value);

请告诉我如何制作这样的眼睛：

在此处输入图像描述

我尝试使用边界半径，但有些东西不起作用。

const pup = document.querySelector('#pup');
const container = document.querySelector('.lien');

let cursor = {x: 0, y: 0}; 
let position = {x: 0, y: 0};

let width=500, height=500; 
let radius = 20; 
let speedMultiplier = 1e-3; 
let lastTime; 
let frames = 5e5;

function onMouseMove(event){
  const bounds = container.getBoundingClientRect();
  cursor.x = event.clientX - bounds.left - bounds.width / 2;
  cursor.y = event.clientY - bounds.top - bounds.height / 2;
  cursor.length = Math.sqrt(cursor.x * cursor.x + cursor.y * cursor.y);
  cursor.x *= radius / cursor.length;
  cursor.y *= radius / cursor.length;
}

document.addEventListener("mousemove", onMouseMove);

function loop(timestamp) { 
  const deltaTime = lastTime ? timestamp - lastTime : 0;
  lastTime = timestamp;
  if (0 === deltaTime) {
    if (--frames > 0) return requestAnimationFrame(loop);
    else return;
  }

  const multiplier = speedMultiplier * deltaTime;

  const vector = {
    x: cursor.x - position.x,
    y: cursor.y - position.y,
  }; 
 
  position.x += vector.x * multiplier;
  position.y += vector.y * multiplier;
  
  // if(position.x<0) position.x = 0;
  // if(position.x>width-radius*2) position.x = width-radius*2;

  // if(position.y<0) position.y = 0;
  // if(position.y>height-radius*2) position.y = height-radius*2;
  
  pup.setAttribute('transform', `translate(${position.x}, ${position.y})`);
  
  if (--frames > 0) requestAnimationFrame(loop);
  else console.log("Out of frames");
}

requestAnimationFrame(loop);

能否请您告诉我如何将以下公式应用于与滑块的交互：第一个值 * 第二个值 = 总量，并将结果值显示在 DOM 中。

在计算中不应考虑滑块值

我失败的代码：

$(document).ready(function(){
  $('#range-yellow').range({
    min: 100,
    max: 1000,
    start: 200,
    onChange: function(value) {
      $('#display-3').html(value);
      let calc =  oneItem * twoItem
      sumItem.text(calc);
    }
  });
});





let oneItem = $(".range-price-item-1");

let twoItem = $(".range-price-item-2");

let sumItem = (".range-price-item-3");

如何正确与 slick 中的断点交互。滑块不应在笔记本电脑和其他大屏幕上处于活动状态，而只能在移动设备和平板电脑上处于活动状态。你能告诉我如何使用响应属性来做到这一点吗？

$('.slider').slick({
    dots: true,
    responsive: [{
            breakpoint: 1024,
            settings: "unslick"
    }]
  });
.slider {
  display: flex;

你能告诉我如何进行以下计算：

#savingsCoins / #range-price-item = savingsGains

难点在于获取输入范围的值并进一步与之交互

请告诉我如何在网站上实现动画。我希望它看起来像这样作为背景： 在此处输入图像描述

动画逻辑很简单：你需要半圆从小到大出现，以此类推。请告诉我如何使用关键帧来实现这一点。

.container {
  margin: 0 auto;
  background: #FF6666;
  width: 600px;
  height: 600px;
}

header:before {
  content: "";
  position: absolute;
  width: 5em;
  height: 10em;
  border: 2px solid red;
  border-radius: 100% 0 0 100% / 50% 0 0 50%;
  background: mistyrose;
}
<header>
  <div class="container">
    <p>test</p>
  </div>
</header>

请告诉我为什么动画不适合我。我使用@keyframes。我在哪里做错了？

.wrapper {
  margin: 0 auto; 
  width: 500px;
  height: 500px;
  background: #FFCC99;
}

.circle { 
  width: 100px;
  height: 100px;
  background: #FF6666;
  border-radius: 100%;
  animation-name: circle;
  animation-duration: 2s;
}


@keyframes circle{
  0% {
    left: 0%;
  }
  
  50% {
    
  }
  
  
  100% {
    left: 100%;
  }
}
<div class="container">
  <div class="wrapper">
    <div class="circle">
      
    </div>
  </div>
</div>
