Easyui Expand the rows in the DataGrid display details

@author YHC

The DataGrid can change its view to show different effects. Using the detailed view, the DataGrid can display the expand button ("+" or "-") to the left of the data row, and the user can expand a row to display an additional detail.

View Demo

Step 1: Create a DataGrid

<table id= "DG" style= "width:500px;height:250px" url= "Data/datagrid_data.json" title= "Datagrid-expand Row" Singleselect= "true" fitcolumns= "true" >  
    <thead>  
        <tr>  
            <th field= "itemid" width= "60" >item id</th>  
            <th field= "ProductID" Width= "no" >product id</th> <th field=  
            "ListPrice" "Align=" right "width=" >list price</th> <th field= "UnitCost" align= "right" width= "," >unit cost  
            </th>  
            <th field= "status" width= "M" align= "center" >Status</th>  
        </tr>  
    </ Thead>  
</table>  

Step 2: Set up a detailed view for the DataGridUsing the Detailed view, remember: the introduction of the view script file on the head of your page.

<script type= "Text/javascript" src= "Http://www.jeasyui.com/easyui/datagrid-detailview.js" ></script>  

$ (' #dg '). DataGrid ({  
    View:detailview,  
    detailformatter:function (index,row) {return  
        ' <div id= ' ddv-' + Index + ' "style=" padding:5px 0 "></div>";  
    },  
    onexpandrow:function (index,row) {  
        $ (' #ddv-' +index ). Panel ({  
            border:false,  
            cache:false,  
            href: ' datagrid21_getdetail.php?itemid= ' +row.itemid,  
            Onload:function () {  
                $ (' #dg '). DataGrid (' Fixdetailrowheight ', index);  
            }  
        });  
        $ (' #dg '). DataGrid (' Fixdetailrowheight ', index);  
    }  
});  

We define the Detailformatter function to tell the DataGrid how to render the detailed view, in which case we return a simple ' <div> ' element that will act as a container for the most detailed content.

Note: The details are empty, when the user clicks on the expand button (' + '), the Onexpandrow event will be triggered, so we can write some code to load the AJAX details, and finally we call the Fixdetailrowheight method to fix the row height when the details are loaded.

Step 3: Server-side code

datagrid21_getdetail.php

<?php $itemid = $_request[' itemid '];  
$content = file_get_contents (' Data/datagrid_data.json ');  
$data = Json_decode ($content, true);  
    foreach ($data [' Rows '] as $item) {if ($item [' itemid '] = = $itemid) {break; }?> <table class= "dv-table" border= "0" style= "width:100%;" > <tr> <td rowspan= "3" style= "width:60px" > <?php echo "&  
            Lt;img src=\ "images/$itemid. gif\" style=\ "height:50px\"/> "; ?> </td> <td class= "Dv-label" >item ID: </td> <td><?php echo $i tem[' itemid '];? ></td> <td class= "Dv-label" >product id:</td> <td><?php echo $item [' Produ Ctid '];?  
        ></td> </tr> <tr> <td class= "Dv-label" >list Price: </td> <td><?php echo $item [' ListPrice '];? ></td> <td class= "Dv-label" &Gt Unit cost:</td> <td><?php echo $item [' unitcost '];? ></td> </tr> <tr> <td class= "Dv-label" >attribute: </td> & LT;TD colspan= "3" ><?php echo $item [' attr1 '];?   ></td> </tr> </table>
