Bootstrap,模态框自动勾选,值传递
场景:
有一个这样的需求, 在父页面有一个table, 在table中有每一行都有一个更新按钮, 用来更新此行数据关联的另一组完整数据, 在点击按钮时, 直接弹出新的table, 并且需要将默认已经关联的数据进行勾选处理. 如下所示.
1.父页面
效果
- 图一为父页面 domain_list : 展示某列表信息,其中
绑定主机是涉及调用 子页面的 btn
此页面代码如下, (后端主要使用了python, Django, 使用了模板语言. 这里不是重点)
{% extends '_base_list.html' %} {% load i18n static %} {% block custom_head_css_js %} <style> #domainSteps { padding-left: 7%; width: 35%; margin:10px auto; } .step-item { display: inline-block; line-height: 32px;

代码分析
body代码块中,
{% include 'assets/_asset_list_modal.html' %}是用来加载bootstrap的模态框,即子页面initTable()用来初始化父页面的table. 重点在targets: 5, createdCell: function (td, cellData, rowData)第六列展示了三个button样式. 分别是bindHost(绑定主机),update_btn(更新),del_btn(删除), 每一个button上面绑定一个`click事件, 事件再绑定api接口删除btn事件如下,不多赘述
<script> ... .on('click', '.btn-delete', function () { var $this = $(this); var $data_table = $('#domain_list_table').DataTable(); var name = $(this).closest("tr").find(":nth-child(2)").children('a').html(); var uid = $this.data('uid'); var the_url = '/ops-audit{% url "api-assets:domain-detail" pk=DEFAULT_PK %}'.replace('{{ DEFAULT_PK }}', uid); objectDelete($this, name, the_url); setTimeout(function () { $data_table.ajax.reload(); }, 1500); }) <script>绑定主机btn click事件如下
<script> .on('click', '.btn-bind', function () { var $this = $(this); var aid = $this.data('aid'); var $id_assets = $('#id_assets'); $id_assets.attr("aid",aid); $('#asset_list_modal').modal('show'); }); </script>说明
- 此点击事件其实实现了两个api的调用①获取当前绑定资产的原有列表;②更新domain资产
- aid为当前domain的pk值,用来传递给子页面, 然后调用相应的api
#id_assets为子页面中<input>标签 id值, 用来接收父页面传递子页面的值#asset_list_modal为子页面 modal(模态框) id值
2. 子页面(modal) 模态框
效果
- 子页面assets_list用来展示所有的资产; 初始化时, 必须勾选已经绑定的资产; 提交按钮时用来 更新domain的assets.
