Title: MVC3 + Json + uasyui combobox
Post by: hahadelphi on July 15, 2014, 01:38:24 AM

I am using MVC3 and combobox

my cshtml is

Code:

<script type="text/javascript">

    $('#c_MENU_ID').combobox({
        url: '@Url.Action("GetMenu","Menu")'
    });
</script>

and action is

Code:

public JsonResult GetFatherMenu()
{
    var q = from e in db.MENUS_V
	    where e.MENU_ID > 0
	    select new
	    {
		menu_id = e.MENU_ID,
		menu_name = e.MENU_NAME
	    };
    var result = q.ToList();
    Dictionary<string, object> json = new Dictionary<string, object>();
    json.Add("total", q.ToList().Count);
    json.Add("rows", result);
    return Json(json, JsonRequestBehavior.AllowGet);
}

Now i know that the combo box only accept
[{
"MENU_ID":1,
"MENU_NAME":"text1"
},{
"MENU_ID":2,
"MENU_NAME":"text2"
}]

not
{"rows":
[{
"MENU_ID":1,
"MENU_NAME":"text1"
},{
"MENU_ID":2,
"MENU_NAME":"text2"
}]
}

what can i do in the action to return the correct json? Thanks

Please use the 'loadFilter' function to convert your original data to the standard data format.

Code:

$('#c_MENU_ID').combobox({
    url: ...,
    loadFilter:function(data){
    	return data.rows;
    }
});

i also use this action, it works

Code:

        public JsonResult GetFatherMenu()
        {
	  var q = from e in db.MENUS_V
	    where e.MENU_ID > 0
	    select new
	    {
		menu_id = e.MENU_ID,
		menu_name = e.MENU_NAME
	    };
            var result = q.ToList();
            JsonResult json = new JsonResult();
            json.Data = q.ToList();
            return Json(json.Data, JsonRequestBehavior.AllowGet);
        }
