如题
这个类负责把datatable转换为layui表格可以显示的内容。
适合配合表格url字段的webapi服务端，为其返回响应字符串。
代码如下：
using System;
using System.Web;
using System.Text;
using System.Data;
using System.Net.Http;
namespace MyClass
{
public class Layui_helper
{
static string datatable2json(DataTable table)
{
StringBuilder jsonBuilder = new StringBuilder();
jsonBuilder.Append("\"data\":[");
for (int i = 0; i < table.Rows.Count; i++)
{
jsonBuilder.Append("{");
for (int j = 0; j < table.Columns.Count; j++)
{
jsonBuilder.Append("\"");
jsonBuilder.Append(table.Columns[j].ColumnName);
jsonBuilder.Append("\":\"");
jsonBuilder.Append(table.Rows[i][j].ToString());
jsonBuilder.Append("\",");
}
jsonBuilder.Remove(jsonBuilder.Length - 1, 1);
jsonBuilder.Append("},");
}
jsonBuilder.Remove(jsonBuilder.Length - 1, 1);
jsonBuilder.Append("]");
return jsonBuilder.ToString();
}
//送入一个datatable，返回一个layui支持的表格字符串(HttpResponseMessage格式)
public static HttpResponseMessage get_Layui_table(DataTable dt,int count=0,int status=0)
{
StringBuilder s = new StringBuilder();
HttpResponseMessage responseMessage;
if(count==0)
{
count = dt.Rows.Count;
}
s.Append("{\"code\":");
s.Append(status.ToString() + ",");
s.Append("\"count\":");
s.Append(count.ToString() + ",");
s.Append(datatable2json(dt));
s.Append("}");
responseMessage = new HttpResponseMessage { Content = new StringContent(s.ToString(), Encoding.GetEncoding("UTF-8"), "text/plain") };
return responseMessage;
}
}
}
//对应前台页面格式开始
/*
<table id="demo" lay-filter="test"></table>
<script src="~/layui/layui.js"></script>
<script>
layui.use('table', function () {
var table = layui.table;
table.render({
elem: '#demo'
, height: 512
, width: 600
//, data:[{ "id": "1", "姓名": "山本0", "年龄": "15" }, { "id": "2", "姓名": "山本1", "年龄": "16" }]
, url: '/api/data/' //数据接口，默认会自动传递两个参数：?page=1&limit=30(初始值对应下面的limit和curr)
, cols: [[ //表头
{ field: 'id', title: 'ID', width: 80, fixed: 'left' }
, { field: '姓名', title: '名字', width: 80 }
, { field: '年龄', title: '年纪', width: 80}
]]
//, limit: 5//设定初始每页记录条数
, page: {
layout: ['limit', 'count', 'prev', 'page', 'next', 'skip'] //自定义分页布局
, limits: [15, 23, 36]//选择每页显示几条，返回或直接设置用
, groups: 4 //连续出现的页码个数，设置用
, first: false //导航中不显示首页
, last: false //导航中不显示尾页
//, curr: 5 //设定初始在第 5 页
}
});
});
</script>
*/
//对应前台页面格式结束
