上下文
我有一个GET加载 .ejs 文件的路由,该文件根据传递的变量 accounts 的长度将数据行添加到表中。这里accounts是一个字典数组,键为 _id, type, nickname, rewards, balance, customer_id

    <% if (accounts.length > 0) { %>
<% accounts.forEach(account => { %>
<tr class="blue-grey lighten-3 account-row">
<th scope="row" class="account-id"><%= account._id %></th>
<td><%= account.type %></td>
<td><%= account.nickname %></td>
<td><%= account.rewards %></td>
<td>$<%= account.balance %></td>
<td><%= account.customer_id %></td>
<td>
<span class="table-remove">
<button type="button" class="btn btn-danger btn-rounded btn-sm my-0 remove" data-toggle="modal" data-target="#removeAccountModal">
Remove
</button>
</span>
</td>
<div class="modal fade" id="removeAccountModal" tabindex="-1" role="dialog" aria-labelledby="removeAccountModalLabel"
aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="removeAccountModalLabel">You are about to remove this account</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
<div class="modal-body">
CAUTION!!!
<br>
<br>
Removing this account will delete all the data associated with it. You must visit a local branch to retrieve any monies left residing in the account.
</div>
<div class="modal-footer">
<button type="button" class="btn grey darken-1" data-dismiss="modal">Cancel</button>
<form id="remove-form" action="/" method="POST">
<button id="removeAccount" class="btn btn-primary" type="submit">Remove Account</button>
</form>
</div>
</div>
</div>
</div>
</tr>
<% }) %>

问题
每行数据上都有一个删除按钮,用于打开 Bootstrap 模式,确认用户确实想要删除该行的数据。在模式中提交后,这将启动 DELETE请求的形式为form元素。

我想传递所选行的关联 account._id变量,以便我可以修改 formaction属性为/<%= account._id %>/?_METHOD=DELETE .

我在访问模式的父窗口 DOM 元素时遇到问题。

我的jQuery代码如下:

<script>
$(document).ready(function () {
console.log("loaded and ready to go!"); // works as expected
var $remove = $(".remove"); // works as expected
console.log($remove.length); // works as expected
$(".remove").click(() => {
console.log("I'm in the modal!") // works as expected
var $parent = $(this).parent().closest("tr"); // find row
console.log($parent); // w.fn.init [prevObject: w.fn.init(0)]
var $account_id = $parent.find("th"); // find account id
console.log($account_id); // w.fn.init [prevObject: w.fn.init(0)]
console.log($account_id.text()); // returns blank type string
$("#remove-form").prop("action", "/" + $account_id + "?
_method=DELETE"); // change action attribute to account id value
})
});
</script>

尝试的方法:

console.log(window.parent.$(this).closest("tr"));       
// returns w.fn.init [prevObject: w.fn.init(1)]

最佳答案

您已将模态框放置在 forEach 内环形。所以你不只有一个模态,而是每一行都有一个。这里的问题是您分配了相同的 id removeAccountModal对于他们所有人。尝试为每个模态分配一个唯一的 id,例如:

<div class="modal fade" id="<%= account._id %>" tabindex="-1" role="dialog" aria-labelledby="removeAccountModalLabel" aria-hidden="true">

并在每个删除按钮上将 data-target 替换为

data-target="#<%= account._id %>"

所以你有独特的模态,现在你可以放置 <%= account._id %>直接在操作属性中
