用jquery easyui datagrid

$(function(){


            product = $('#product').datagrid({


            nowrap:false,


            striped:true,


            url:'listProduct.action', 

            sortName: 'pn',


            sortOrder: 'desc',


            idField:'pn',  

        frozenColumns:[[
            {field:'ck',checkbox:true},
        ]],

            {field:'pn',title:'P/N',width:100,align:'center'},  
            {field:'description',title:'Description',width:120,align:'center'},  
            {field:'type',title:'Type',width:100,align:'center'},  
            {field:'brand',title:'Brand',width:60,align:'center'},

            {field:'quantity',title:'Quantity',width:60,align:'center'},  
            {field:'dateCode',title:'Date Code',width:60,align:'center'},  
        ]], 
        pagination:true,
        toolbar:[{
            text:'Add',  
            iconCls:'icon-add',  
            handler:function(){  
                alert('add')  
            }
        },'-',{  
            text:'Edit',  
            iconCls:'icon-edit',  
            handler:function(){  
                alert('edit')  
            }
        },'-',{  
            text:'Delete',  
            iconCls:'icon-remove',  
            handler:function(){
                delRows(product);
            }
        }]  
    });  
});  

function delRows(table) {

    var arr = getSelectedRows(table);

    if (arr.length > 0) {

        $.messager.confirm('Prompt', 'Are you sure to delete the selected record(s)', function (data) {

            if (data) {

                $.ajax({

                    url: 'delProduct',

                    type: 'get',

                    dataType: 'json',

                    data: {"id":"[{'id':3},{'id':5}]"},

                   // timeout: 1000,

                    error: function () {

                        $.messager.alert('Error', 'Delete Failure!', 'error');

                    },

                    success: function (data) {

                        if (data.success) {

                            grid.datagrid('reload');

                            grid.datagrid('clearSelections');

                        } else {

                            $.messager.alert('Error', data.msg, 'error');

                        }

                    }

                });

            }

        });

    } else {

        $.messager.show({

            title: 'Wraning',

            msg: 'Please select the record you want to delete!'

        });

    }

function getSelectedRows(table) {

    var ids = [];

    var rows = table.datagrid('getSelections');

    for (var i = 0; i < rows.length; i++) {

        ids.push(rows[i].id);

    }

    alert(ids.join('\n'));

    return ids;

}

现在主要是data的数据，应该怎么样得到，多选的
现在写的红色部分是测试用的，主要是想传数组

对jquery不大熟悉，请大家指教


问题补充
嗯，这个是我加多了，删除了，谢谢
我就是想在前台用户选择了 多行数据（通过checkbox），然后我要在后台把这些删除，现在问题是不知道怎么样把这些选择的id传到后台

Answer 1

[code="java"][/code][code="java"]
function getSelectedRows(table) {
var ids = [];
var rows = table.datagrid('getSelections');
for (var i = 0; i < rows.length; i++) {
ids.push(rows[i].id); s.join('\n'));
return ids;
}

[/code]

我对easyui还是比较熟悉的，首先问个问题，你的删除不就是要最终从数据库中删除吗？

1. 你用过sql语句中的in关键字吗？
   delete from TableA where id in (1,3,4,5,6);

2. 你知道js的数组中有个join方法,那么你现在能联想到什么？

对了，将你的id数组转换成 "1,2,3,4,5"的形式传到后台
[code="java"]
function getSelectedRows(table) {
var ids = [];
var rows = table.datagrid('getSelections');
for (var i = 0; i < rows.length; i++) {
ids.push(rows[i].id);
return ids.join(",");
}

[/code]

然后通过：
[code="java"]
$.ajax({
url:'XXX.action?ids='+getSelectedRows(table),
method:'POST',
dataType:'json',
success:function(msg){
},
error:function(msg){
}
...
});

[/code]
