Question

我试过了：

$(document).ready(function(e) {
    $(body').mousemove(function (evt) {

        // i want code 1.
        $(evt.target).mouseover('background-color', 'blue');
        $(evt.target).leave('background-color', 'before color');

        // i want code 2.
        $(evt.target.parent).mouseover('background-color', 'yellow');
        $(evt.target.parent).leave('background-color', 'before color');
    }
}

我不知道这个像素化代码。请帮帮我们!!

谢谢。

Answer 1

$(document).ready(function(e) {

  $('.box').on('mouseover', function() {
    $(this).css({
      'background-color': 'blue'
    });
  });

  $('.box').on('mouseout', function() {
    $(this).css({
      'background-color': 'yellow'
    });
  });
  
});

.box {
  width: 100px;
  height: 100px;
  border: 1px solid #000;
  margin: 30px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="box"></div>

Answer 2

您可以改为使用hover事件：

$(".element").hover(
  function() {
    $(this).css('background-color', 'yellow'); //When mouse enter
  },
  function() {
    $(this).css('background-color', 'green'); //When mouse leave
  }
);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="element">My div</div>

使用mouseenter和mouseleave添加和删除课程。

＆＃13;

$('.target').mouseenter(function() {
  $(this).addClass("target1");
  $(this).parent().addClass("parent1");
}).mouseleave(function() {
  $(this).removeClass("target1");
  $(this).parent().removeClass("parent1");
});

＆＃13;

.target1 {
  background-color: blue
}

.parent1 {
  background-color: yellow
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="parent">
  "Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo. Nemo enim ipsam voluptatem quia voluptas

  <div class="target">
    <h1>Hover me I show you a result.</h1>
  </div>
</div>
