更改html元素后，我无法调用jquery事件

Question

我正在尝试通过链接点击事件在我已经更改其html之后更改我的模式，但不幸的是它不起作用，我只是一个新学生，所以我想知道为什么这不起作用...

OBS：我是巴西人，所以代码的某些部分将是葡萄牙文。

HTML CODE

<div id="modais" class="mt-5 row">
    <div class="modal fade text-dark mx-auto" id="loginModal" tabindex="-1" role="dialog">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <h5 class="modal-title">Faça login</h5>
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                        <span aria-hidden="true">&times;</span>
                    </button>
                </div>                              
                <div class="modal-body text-center">
                    <form class=" mx-auto col-10 border rounded py-3 px-4">

                    <p class="small"><span class="text-danger">*</span>Para cadastrar quaisquer atividades é necessário ter uma conta admnistrativa.</p>    
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-primary">Entrar</button>
                    <button type="button" class="btn btn-secondary" data-dismiss="modal">Sair</button>
                </div>                      
            </div>
        </div>
    </div>
</div>

Answer 1

如果你说你点击一次更改它，那么点击事件似乎没有注册到#linkModal，可能是因为你需要更改

$("#linkModal").click(function(){

到

$(document).on("click","#linkModal",function(){

很难说出这里发生了什么，因为你没有任何带有ID＆＃34;＃linkModal＆＃34;的元素。在您共享的代码中。
