上下文
我有一个GET
路由加载.ejs文件,该文件根据传递的变量accounts
的长度向表中添加数据行。这里accounts
是一个字典数组,键_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">×</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,打开一个Bootstrap模式,确认用户确实要删除该行的数据。在模态中提交后,这将以DELETE
元素的形式发起form
请求。
我想传递所选行的关联account._id
变量,以便我可以将form
的action
属性修改为/<%= account._id %>/?_METHOD=DELETE
。
我无法访问模态的父窗口DOM元素。
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", "/" + $account_id + "?
_method=DELETE"); // change action attribute to account id value
})
});
</script>
方法尝试:
console.log(window.parent.$(this).closest("tr"));
// returns w.fn.init [prevObject: w.fn.init(1)]
你已经将模态放在forEach
循环中。所以你没有一个模态,而是每行有一个模态。这里的问题是你为所有人分配了相同的id removeAccountModal
。尝试为每个模态分配唯一的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替换数据目标
data-target="#<%= account._id %>"
所以你有独特的模态,现在你可以直接将<%= account._id %>
放在action属性中
谢谢@dimitris tseggenes指出我正确的方向。
每个模态div的独特id
s在这里势在必行。事实证明,id
属性值不能仅仅由数字组成。
我重构了id
和target-data
属性,分别如下所示:
id="account<%= account._id %>id"
data-target=#account"<%= account._id %>id"
