为什么单击图标时模式无法启动？

Question

我一直在尝试各种方法来激活模式，从javascript到直接调用模式都没有成功。页面只需允许单击，然后什么也不做。

我尝试过从javascript文件调用modal，我尝试过从div直接调用modal，我尝试过javascript href，我尝试过检查语法或拼写错误，我尝试过在div、ancor、image和button标记之间交换。

<div class="child flex-child">
    <div class="profile-btn">
        <div class="profile-bubble-parent" data-target="#profileModal" data-toggle="modal" onclick="openProfileModal();" >

            <div class="modal-footer">

            </div>
        </div>
    </div>
</div>

js文件有：

function openProfileModal(){
    setTimeout(function(){
        $('#profileModal').modal('show');    
    }, 230);

}

CSS:

/*===================================================================================

.profile-bubble {
  height: 55px;
  width: 55px;
  border-radius: 50%;
}

}
.title-pen span {

}

.user-profile {
  margin: auto;
    width: 25em; 
  height: 11em;
  background: #fff;
  border-radius: .3em;
}

.user-profile  .username {
  margin: auto;
  margin-top: -4.40em;
  margin-left: 5.80em;
  color: #658585;
  font-size: 1.53em;

.user-profile li {
    margin: 0 auto;
  padding: 1.30em; 
  width: 33.33334%;
  display: table-cell;
  text-align: center;
}

.user-profile span {
    font-family: "varela round", sans-serif;
    color: #e3eeee;
  white-space: nowrap;
  font-size: 1.27em;
  font-weight: bold;
}
.user-profile span:hover {
  color: #daebea;
}

/*===================================================================================
======================================MODAL========================================*/

.modal {
  display: none; /* Hidden by default */
  position: fixed; /* Stay in place */
  z-index: 1; /* Sit on top */
  padding-top: 100px; /* Location of the box */
  left: 0;
  top: 0;
  width: 100%; /* Full width */
  height: 100%; /* Full height */
  overflow: auto; /* Enable scroll if needed */
  background-color: rgb(0,0,0); /* Fallback color */
  background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}

.modal-content {
  background-color: #fefefe;
  margin: auto;
  padding: 20px;
  border: 1px solid #888;
  width: 80%;
}


.close {
  color: #aaaaaa;
  float: right;
  font-size: 28px;
  font-weight: bold;
}

.close:hover,
.close:focus {
  color: #000;
  text-decoration: none;
  cursor: pointer;
}

结果应该是内容的弹出模式。

Answer 1

如果不打算使用jquery，请使用文档API访问HtmleElement节点，然后在其上操作样式属性。

var modal = document.getElementById('profileModal');
modal.style.display = 'block';

因为我不知道CSS的确切性质，所以很难给出更精确的答案。

Answer 2

首先，我将modal正文移到标签外面，并给它一个id，profile ileModal。接下来，我知道它起作用了。
