我正在使用 jstree 在我的项目中创建类别和子类别的菜单。但我没有得到或没有以 jstree 格式显示我的数据。那么,有什么问题。?请帮助我。谢谢....
我的控制器代码
[HttpGet]
public JsonResult GetCatList()
{
IEnumerable<Category> cats = _CategoryBusiness.Select();
return new JsonResult
{
JsonRequestBehavior = JsonRequestBehavior.AllowGet,
Data = cats
};
}
我的模特班
[Serializable]
public class Category
{
[Key]
[DisplayName("Id")]
public int CategoryID { get; set; }
public string CategoryName { get; set; }
public int? SubCategoryID { get; set; }
[ForeignKey("SubCategoryID")]
public virtual Category SubCategory { get; set; }
}
_CategoryBusiness.Select() 是
public List<Category> Select(int id = 0)
{
var selectFrom = _Ctx.Categories.Select(a => a);
var query = selectFrom.Select(a => a);
if(id > 0)
query = query.Where(a => a.CategoryID == id);
return query.ToList();
}
我的查看页面代码是
<script type="text/javascript">
$(function () {
FillJSTree();
});
function FillJSTree() {
$("#onflycheckboxes").jstree({
json_data: {
"ajax": {
"url": "/Categories/GetCatList/",
"type": "GET",
"dataType": "json",
"contentType": "application/json charset=utf-8",
}
},
//checkbox: {
// real_checkboxes: true,
// checked_parent_open: true
//},
plugins: ["themes", "json_data", "ui"]
});
}
</script>
. . . . ..
<div id="onflycheckboxes">
</div>
