EasyUI DataGrid结合ThinkPHP实现增删改查操作——

EasyUI DataGrid结合ThinkPHP实现增删改查操作———初学者

EasyUI是基于jQuery的用户界面插件集合；DataGrid是数据表格；

ThinkPHP是快速、简单的基于MVC和面向对象的轻量级PHP开发框架。

使用的集成开发环境是 WAMPSever，（wampserver是一个集成了Apache、PHP和MySQL的开发套件，而且支持不同PHP版本、MySQL版本和Apache版本的切换）

效果如下：

主要代码如下

1、定义一个表格

<span style="color: #0000ff;"><span style="color: #800000;">table </span><span style="color: #ff0000;">id</span><span style="color: #0000ff;">="dg"</span><span style="color: #ff0000;"> class</span><span style="color: #0000ff;">="easyui-datagrid"</span><span style="color: #ff0000;"> title</span><span style="color: #0000ff;">="DataGrid Complex Toolbar"</span><span style="color: #ff0000;"> style</span><span style="color: #0000ff;">="width:700px;height:250px"</span><span style="color: #ff0000;">            data-options</span><span style="color: #0000ff;">="rownumbers:true,singleSelect:true,url:'{:U(read)}',method:'get',toolbar:'#tb'"</span><span style="color: #0000ff;">></span>        <span style="color: #0000ff;"><span style="color: #800000;">thead</span><span style="color: #0000ff;">></span>            <span style="color: #0000ff;"><span style="color: #800000;">tr</span><span style="color: #0000ff;">></span>                <span style="color: #0000ff;"><span style="color: #800000;">th </span><span style="color: #ff0000;">data-options</span><span style="color: #0000ff;">="field:'ID',width:80,align:'center'"</span><span style="color: #0000ff;">></span>ID<span style="color: #0000ff;"></span><span style="color: #800000;">th</span><span style="color: #0000ff;">></span>                <span style="color: #0000ff;"><span style="color: #800000;">th </span><span style="color: #ff0000;">data-options</span><span style="color: #0000ff;">="field:'Product',width:100"</span><span style="color: #0000ff;">></span>Product<span style="color: #0000ff;"></span><span style="color: #800000;">th</span><span style="color: #0000ff;">></span>                <span style="color: #0000ff;"><span style="color: #800000;">th </span><span style="color: #ff0000;">data-options</span><span style="color: #0000ff;">="field:'Content',width:500,align:'center'"</span><span style="color: #0000ff;">></span>Content<span style="color: #0000ff;"></span><span style="color: #800000;">th</span><span style="color: #0000ff;">></span>            <span style="color: #0000ff;"></span><span style="color: #800000;">tr</span><span style="color: #0000ff;">></span>        <span style="color: #0000ff;"></span><span style="color: #800000;">thead</span><span style="color: #0000ff;">></span><span style="color: #0000ff;"></span><span style="color: #800000;">table</span><span style="color: #0000ff;">></span></span></span></span></span></span></span>

　　class="easyui-datagrid"是easyui里面自定义的格式，data-options用来初始化属性，这里面的属性包括rownumbers显示行数，singleSelect表示行的选中状态；

url:'{U(read)}'首先，ThinkPHP的U方法（参考：http://www.thinkphp.cn/info/132.html）用来完成对URL地址的组装，在模板中的调用采用 {:U('地址', '参数'…)} 的方式，其次，EasyUI采用的数据格式是json,控制器里面的read方法输出一个json格式的数据。toolbar:'#tb'这个是表格的工具栏，就是增加、删除和修改。

定义表格的工具栏如下：

<span style="color: #0000ff;"><span style="color: #800000;">div </span><span style="color: #ff0000;">id</span><span style="color: #0000ff;">="tb"</span><span style="color: #ff0000;"> style</span><span style="color: #0000ff;">="padding:2px 5px;"</span><span style="color: #0000ff;">></span>        <span style="color: #0000ff;"><span style="color: #800000;">a </span><span style="color: #ff0000;">href</span><span style="color: #0000ff;">="javascript:void(0)"</span><span style="color: #ff0000;"> class</span><span style="color: #0000ff;">="easyui-linkbutton"</span><span style="color: #ff0000;"> iconCls</span><span style="color: #0000ff;">="icon-add"</span><span style="color: #ff0000;"> plain</span><span style="color: #0000ff;">="true"</span><span style="color: #ff0000;"> onClick</span><span style="color: #0000ff;">="addPro()"</span><span style="color: #0000ff;">></span><span style="color: #800000;">a</span><span style="color: #0000ff;">></span>        <span style="color: #0000ff;"><span style="color: #800000;">a </span><span style="color: #ff0000;">href</span><span style="color: #0000ff;">="javascript:void(0)"</span><span style="color: #ff0000;"> class</span><span style="color: #0000ff;">="easyui-linkbutton"</span><span style="color: #ff0000;"> iconCls</span><span style="color: #0000ff;">="icon-edit"</span><span style="color: #ff0000;"> plain</span><span style="color: #0000ff;">="true"</span><span style="color: #ff0000;"> onclick</span><span style="color: #0000ff;">="editPro()"</span><span style="color: #0000ff;">></span><span style="color: #800000;">a</span><span style="color: #0000ff;">></span>        <span style="color: #0000ff;"><span style="color: #800000;">a </span><span style="color: #ff0000;">href</span><span style="color: #0000ff;">="javascrtpt:void(0)"</span><span style="color: #ff0000;"> class</span><span style="color: #0000ff;">="easyui-linkbutton"</span><span style="color: #ff0000;"> iconCls</span><span style="color: #0000ff;">="icon-remove"</span><span style="color: #ff0000;"> plain</span><span style="color: #0000ff;">="true"</span><span style="color: #ff0000;"> onclick</span><span style="color: #0000ff;">="removePro()"</span><span style="color: #0000ff;">></span><span style="color: #800000;">a</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"></span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span></span></span></span></span>

注意：这里面的id要和 toolbar：'#tb' 相对应；

2、点击增加和修改的时候要弹出一个对话框，代码如下：

class='easyui-dialog'定义了一个对话框，因为要和后台交互，在这个对话框里面装了一个form，里面的input元素有些需要进行验证，required="true"表示必须填写元素

class="easyui-validatebox"定义了验证失败后的提示，buttons="#dlg-buttons"表示这个对话框下面的两个确认，取消按钮。novalidate表示不验证。

对话框中的按钮：

JS还不是很会，所以参考了网上的代码。 $.messager.show是EasyUI提供的消息提示框（参考：http://www.jeasyui.net/demo/371.html），可以在屏幕右下角显示一个消息窗口。$.messager.confirm是交互式消息，弹出一个消息确认框。var row = $("#dg").datagrid("getSelected");是取得选中行，而row.ID可以取得选中行的数据，其中ID是由field:'ID'决定。

4、控制器里面的代码（IndexAction.class.php）
