Question

我正在尝试通过Jquery动画功能更改引导巨人。但这是行不通的。我希望在单击动画按钮后，超大屏幕尺寸会增加我的屏幕一半。

<div class="content">
    <div class="jumbotron jumbotron-fluid">
        <div class="container">
            <div class="display-4">
                <div class="display-4 heading">JQuery Practice</div>
                <p class="lead">
                This is Jquery Practice Session. Jquery is a javascript 
                library to make developers life better.
                Let's make our jQuery learning fun.
                </p>
            </div>
        </div>
    </div>
</div>

<div class="d-flex justify-content-center">
    <div class="p-2">
        <button type="button" class="btn btn-success" id="animate">Animate</button>
    </div>
</div>

jQuery是：

$(document).ready(function() {
  $("animate").click(function() {
    $("jumbotron").animate({
      height:50vh
    });
  });
});

Answer 1

$(document).ready(function(){
  $("#animate").click(function(){
    $(".jumbotron").animate({
      height: "50vh"
    });
  });
});

据我了解，您想animate的jombotron格的高度。试试这个代码，

$("#animate").click(function(){
   $(".jumbotron").animate({
      height: "50vh"
   });
});

Answer 2

这是您使用的是jQuery slim，而不是实际的jQuery。另外，由于animate是id并且jumbotron是类，因此您没有正确选择元素。请检查此工作代码的codepen链接：

希望它对您有帮助。

为什么我的Jquery animate（）函数不起作用？
