Let’s first look at the parameters required for asynchronous request data described in the API:

How to create table in layui

The default parameters are page and limit. You can modify the parameter name as needed. The two parameters are our traditional page number and page size.

where is other additional parameters. You can choose whether to pass the value according to the needs of the front page.

Here I modified the default value (in the table.js file) and changed the original page and limit to Start and Length:

The following is the background Action logic:

public ActionResult GetTableData(string Start, string Length, string KeyWords, string StartTime,string EndTime)
        {
            if (string.IsNullOrWhiteSpace(Start) || string.IsNullOrWhiteSpace(Length))
            {
                return Json(new { Success = false, Message = "" }, JsonRequestBehavior.AllowGet);
            }
            var demoList = orderdal.getDemoData(Start, Length, KeyWords, StartTime, EndTime);
            return Json(demoList, JsonRequestBehavior.AllowGet);
        }

Here we add three parameters in addition to the default two parameters, which correspond to the front-end search box. The time period is quite special and is the time box that comes with layui, as shown below:

When printed out in the front desk, we can see the following format:

So it needs to be converted to facilitate background filtering:

Then paste the code for the return data format:

  public LayTableResult<V_MoveUnionDeployCloudBase> getDemoData(string Start, string Length, string KeyWords, string StartTime, string EndTime)
        {
            ....==.
            LayTableResult<V_MoveUnionDeployCloudBase> result = new LayTableResult<V_MoveUnionDeployCloudBase>()
            {
                code = seleResult.Any() ? 0 : 1,
                count = resultCount,//总条数
                data = seleResult,
                msg = ""
            };
 
            return result;
        }

The LayTableResult here is a class defined by yourself according to the needs of the page, as follows (T is the table you want to return ):

 public class LayTableResult<T>
    {
        public int code { get; set; }
        public string msg { get; set; }
        public int count { get; set; }
        public List<T> data { get; set; }
 
    }

At this point, all the logic has been written. One thing that needs to be emphasized is that when you perform conditional filtering, you should add an attribute to the search button, as follows:

Then the operation column is bound in the external html:

If you need to customize the column, use the LayUI framework The built-in template syntax, the following picture is a time format conversion of the application date column:
