javascript - 将 div 切换到计算位置

Question

我有下面的代码。我希望它能将一个 div 动画化到一个计算好的位置，但有些事情是不可能的，或者我犯了一个错误。有人可以帮忙吗？

    $(document).ready(function() {
      var is_Clicked = false;
      $("#togglebutton").click(function() {
        if (is_Clicked) {
          $('#myToggleDiv').css('float','left');
          $("#myToggleDiv").animate({
            left: '0%'
          });
          is_Clicked = false;
        } else {
           $('#myToggleDiv').css('float','right');
            $("#myToggleDiv").animate({
                $('#myToggleDiv').css('right','calc(100vw - 40px));
          });
          is_Clicked = true;
        }
      });
    });

    $(document).ready(function() {
      document.getElementById("myText").innerHTML = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.<br><br>Lorem Ipsum is simply dummy text of the printing and typesetting industry.

html,
body {
  width: 100%;
  height: 100%;
}

#header {
  width: 100%;
  height: 20%;
  float: left;
  border: 1px solid;
}

#myToggleDiv {
 position: relative;
  border: 1px solid;
}

#togglebutton {
  width: 10%;
  height: 40%;
  margin-right: 5px;
  margin-top: 5px;
  float: right;
}

@media screen and (min-width: 1366px) {
  #myToggleDiv {
    width: 60vw;
  }
}

@media screen and (max-width: 1365px) {
  #myToggleDiv {
    width: 70vw;
  }
}

@media screen and (max-width: 1024px) {
  #myToggleDiv {
    width: 90vw;
  }
}

@media screen and (max-width: 800px) {
  #myToggleDiv {
    width: 100vw;
  }
}

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

  <input type="button" value="Toggle" id="togglebutton">
  <p id="myText"></p>
</div>

Answer 1

那是因为 .animate 需要一个对象。所以像这样改变你的代码:

$("#myToggleDiv").animate({
       'right':'calc(100vw - 40px)'
});

注意将 'calc(100vw - 40px)' 放在引号内
