3、easyUI-创建 CRUD可创建展开行明细编辑dataGrid（表格）

同样在上一节中讲到可以编辑的表格，现在讲一般用到的最后一个datagrid（表格）相关的展开明细可编辑的表格；

第三中表格主要应用场景在：列出表格信息，然后点击可以查看详细信息（此处是全部可以编辑，可以改写），举个例子，人员信息有很多字段，但是一般在列表信息只显示人员相关的主要字段，但是如果想看人员所有信息的话，就可通过这个方法来实现，声明一点，这里的是可以编辑的，你可以做成不可编辑；

再说两句，比如在第一节的时候，如果只提供一张表格表单，进行添加信息，然后在列表页中列出人员信息，列出的人员信息不允许编辑，只可以查看，就可以使用这节的表格；

开始任务：

首先在网上下载datagrid-detailview.js文件（稍后附出代码文件的js）；

然后新建一个index.php,将js文件引入；

后台代码使用第二节的，无需更改，不做介绍；

第一步，先看效果图：

　　展开明细，可编辑（你可以改写成不可修改，只可以看）

　　添加明细视图：

第二步：编写index.php页面代码

    $(function(){
        $('#dg').datagrid({
            view: detailview,
            detailFormatter:function(index,row){
                return '<div class="ddv"></div>';
            },
            onExpandRow: function(index,row){
                var ddv = $(this).datagrid('getRowDetail',index).find('div.ddv');
                ddv.panel({
                    border:false,
                    cache:true,
                    href:'./page/show_form.php?index='+index,
                    onLoad:function(){
                        $('#dg').datagrid('fixDetailRowHeight',index);
                        $('#dg').datagrid('selectRow',index);
                        $('#dg').datagrid('getRowDetail',index).find('form').form('load',row);
                    }
                });
                $('#dg').datagrid('fixDetailRowHeight',index);
            }
        });

    });
    </script>
</head>
<body>

        描述：list
    -->
    <table id="dg" title="用户列表" class="easyui-datagrid" url="./data/crud/userAction.php?flag=list"  style="width:100%;height: 600px;"  toolbar="#toolbar" rownumbers="true" pagination="true"  fitColumns="true" singleSelect="true">
        <thead>
            <tr>
                <th field="fname" width="50" >名</th>
                <th field="lname" width="50" >姓</th>
                <th field="sex" width="50" >性别</th>
                <th field="phone" width="50" >联系电话</th>
                <th field="email" width="50" >邮件</th>
            </tr>
        </thead>
    </table>
    <div id="toolbar">
           <a href="#" class="easyui-linkbutton" iconCls="icon-add" plain="true" onclick="newItem()">添加</a>
        <a href="#" class="easyui-linkbutton" iconCls="icon-remove" plain="true" onclick="destroyItem()">删除</a>
    </div>
</body>
<html>

首先看table部分，url自动请求地址获取用户信息列表数据展示，pagination="true"表示带分页，然后就是toolbar下的两个方法newItem()和destroyItem()，其中destroyItem()方法和之前第一节的一样；

然后我们看javascript部分的一段代码：这种格式记住，理解，直接拿来用就可以，使用 'detailFormatter' 函数来生成行明细内容，当用户点击行展开按钮（'+'）时，'onExpandRow' 事件将被触发，我们将通过 ajax 加载编辑表单（form）。调用 'getRowDetail' 方法来得到行明细容器，在行明细中创建面板（panel），加载从 'show_form.php' 返回的编辑表单；

第三步：编写show_form.php即明细行表单

<form method="post">
    <table class="dv-table" style="width:100%;background:#fafafa;padding:5px;margin-top:5px;">
        <tr>
            <td>名</td>
            <td><input name="fname" class="easyui-validatebox" required="true"></input></td>
            <td>姓</td>
            <td><input name="lname" class="easyui-validatebox" required="true"></input></td>
        </tr>
        <tr>
            <td>性别</td>
            <td colspan="3"><input name="sex" class="easyui-validatebox" required="true"></input></td>
        </tr>
        <tr>
            <td>电话</td>
            <td><input name="phone"></input></td>
            <td>邮件</td>
            <td><input name="email" class="easyui-validatebox" validType="email"></input></td>
        </tr>
    </table>
    <div style="padding:5px 0;text-align:right;padding-right:30px">
        <a href="#" class="easyui-linkbutton" iconCls="icon-save" plain="true" onclick="saveItem(<?php echo $_REQUEST['index'];?>)">Save</a>
        <a href="#" class="easyui-linkbutton" iconCls="icon-cancel" plain="true" onclick="cancelItem(<?php echo $_REQUEST['index'];?>)">Cancel</a>
    </div>
</form>

第四步：实现saveItem(),cancelItem(),newItem(),destroyItem()四个方法

实现newItem()方法：

function newItem(){
   $('#dg').datagrid('appendRow',{isNewRecord:true});
   var index = $('#dg').datagrid('getRows').length - 1;
   $('#dg').datagrid('expandRow', index);
   $('#dg').datagrid('selectRow', index);
}

appendRow追加一个新行。新行将被添加到最后的位置，给他一个{isNewRecord:true}属性，可以在saveItem方法中判断，

getRows返回当前所有行；

实现saveItem()方法：

实现cancelItem()方法：

实现destroyItem()方法：

最后附上源码：

datagrid-detailview.js

$.extend($.fn.datagrid.defaults, {
    autoUpdateDetail: true  // Define if update the row detail content when update a row
});

var detailview = $.extend({}, $.fn.datagrid.defaults.view, {
    render: function(target, container, frozen){
        var state = $.data(target, 'datagrid');
        var opts = state.options;
        if (frozen){
            if (!(opts.rownumbers || (opts.frozenColumns && opts.frozenColumns.length))){
                return;
            }
        }
        
        var rows = state.data.rows;
        var fields = $(target).datagrid('getColumnFields', frozen);
        var table = [];
        table.push('<table class="datagrid-btable" cellspacing="0" cellpadding="0" border="0"><tbody>');

                classValue = css['class'] || '';
                styleValue = css['style'] || '';
            }
            
            var cls = 'class="datagrid-row ' + (i % 2 && opts.striped ? 'datagrid-row-alt ' : ' ') + classValue + '"';

            table.push('<tr id="' + rowId + '" datagrid-row-index="' + i + '" ' + cls + ' ' + style + '>');
            table.push(this.renderRow.call(this, target, fields, frozen, i, rows[i]));
            table.push('</tr>');
            
            table.push('<tr style="display:none;">');
            if (frozen){
                table.push('<td colspan=' + (fields.length+(opts.rownumbers?1:0)) + ' style="border-right:0">');
            } else {
                table.push('<td colspan=' + (fields.length) + '>');
            }

            table.push('<div class="datagrid-row-detail">');
            if (frozen){
                table.push('&nbsp;');

            table.push('</div>');

            table.push('</td>');

        }
