标签: javascript checkbox colors

我想在复选框中更改CSS中的身体颜色。怎么做?

HTML -

<label class="switch">
  <input type="checkbox">
  <span class="slider round"></span>
</label> 

JavaScript - 这里要粘贴什么?

CSS - 这里要过去什么?

非常感谢!

好的,既然你是js的新手我已经评论了代码

HTML:

<body>
<p>
  test
</p>
<label class="switch">
  <input type="checkbox" id="test">
  <span class="slider round"></span>
</label> 

JS:

var checkedColor="red"; //the colors of the background
var uncheckedColor="blue" //the colors of the background
document.body.style.backgroundColor =uncheckedColor;//change the color at the begining to keep it consistent
function changeColor(){

  if (document.getElementById("test").checked) { //if it is checked change to  checkedColor
      document.body.style.backgroundColor = checkedColor;
  } 
  else {//if it is not checked change to  uncheckedColor
     document.body.style.backgroundColor =uncheckedColor;
  }
}


document.getElementById("test").addEventListener('click', changeColor); //make the checkbox exeute the function test when being clicked
