html - 模态弹出窗口在表格的下拉菜单中不起作用

Question

我想在我的表格下拉菜单中放置一个 Bootstrap (v3) 模态视图，但它不起作用。当我按下下拉菜单的删除按钮时，屏幕变暗了几秒钟，但没有弹出模态视图。

如果我将模态代码复制到另一个页面进行测试，它会成功运行。

表数据来自后端node.js。如果您需要更多信息，可以告诉我。

.dropdown {
  position: relative;
  display: inline-block;
}

.dropbtn {
  color: white;
  width: 150px;
  height: 60px;
  border: none;
  cursor: pointer
}

.dropdown-content {
  display: none;
  position: absolute;
  right: 0;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  -webkit-box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  -moz-box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  -ms-box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  -o-box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}

.dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

.dropdown-content a:hover,
.dropdown-content a:focus {
  background-color: #f1f1f1;
}

.dropdown:hover .dropdown-content,
.dropdown:focus .dropdown-content {
  display: block;
}

.dropdown:hover .dropbtn,
.dropdown:focus .dropbtn {
  background-color: #3e8e41;
}

我可以在您的代码中看到一个错误，将按钮 href 更改为 data-target。这可能会解决您的问题。

替换这一行:

 <button href="#myModal" data-toggle="modal" class="dropbtn" style="background-color:transparent; border:0;margin-bottom: -10px"><a>Delete</a></button>

与

 <button data-target="#myModal" data-toggle="modal" class="dropbtn" style="background-color:transparent; border:0;margin-bottom: -10px">Delete</button>

data-target="#myModal" 指向模态框的id。
