以上是我从网址获取数据的代码。

关注manageUsers.tpl文件。

<div class="content">
<p> </p>
<h3></h3>
<div class="admin-login-area ui-corner-all">
    <p class="validateTips">All form fields are required.</p>
    <form id="addUserForm">
        <fieldset>
        <label for="name" class="login-label">User Name</label>
        <input type="text" name="u-name" id="u-name" class="text ui-widget-content ui-corner-all">
        <label for="name" class="login-label">Password</label>

                </tr>
            </tfoot>
            <tbody>

            </tbody>

并且在成功获取数据时我已经用collectios的数据填充了表格，并且点击表格中的项目我想要检索整个模型。我在同一个tpl文件中有表格和表格

如何使用backbonejs和下划线js？

Answer 1

首先，将此事件添加到您的视图中：

events : {
    'click .edit-iocn' : 'edit', // in your code you typed `iocn` instead of `icon`
    'click .delete-icon' : 'delete'
}

在没有id='"+d.username+"'和edit_

的情况下，将ID更改为delete_

最后编辑和删除方法：

edit: function(event) {
    var username = event.currentTarget.id;

    var user = usersCollection.where({name: username})[0];
    ...
}

delete: function(event) {
    var username = event.currentTarget.id;

    var user = usersCollection.where({name: username})[0];
    ...
}

Backbonejs：从集合中获取点击模型
