问题

我的问题是我尝试slideToggle()点击<div class='inputs'></div>下的<h2></h2>。另一件事是我没有收到任何错误。

＆＃13;
＆＃13; 
    // MAIN
    function main() {
        $(".toggle-inputs").on("click", function() {
           $(this).find('.inputs').slideToggle();
        });
    }
    
    // LOAD
    $(document).ready(main);

问题在于我必须使用next()而不是find()。

＆＃13;
＆＃13; 
    // MAIN
    function main() {
        $(".toggle-inputs").on("click", function() {
           $(this).next('.inputs').slideToggle();
        });
    }
    
    // LOAD
    $(document).ready(main);

问题是.find()正在查看h2的子元素，在这种情况下，它只是<i>元素，因此它无法找到它的内容寻找。而是首先获取父级，以便在<div class="inputs">中搜索。

＆＃13;
＆＃13; 
// MAIN
    function main() {
        $(".toggle-inputs").on("click", function() {
           $(this).parent().find('.inputs').slideToggle();
        });
    }
    
    // LOAD
    $(document).ready(main);

首先，每个部分需要不同的选择器。等; 

<h2 id="toggle-inputs-students">Add Student

和

<div id="inputs-students">

说到JS部分，你可以使用下面的代码

$( "#toggle-inputs-students" ).click(function() {
  $( "#inputs-students" ).slideToggle( "slow", function() {
// Animation complete.
  });
});
