Html Editor Plugin – bootstrap-wysiwyg-editor

Reference http://www.c-sharpcorner.com/uploadfile/3d39b4/bootstrap-wysiwyg-editor-in-asp-net-mvc/

 

 

Introduction

This article introduces how to implement a Bootstrap WYSIWYG editor in an ASP.NET MVC application. There are many editors available over the internet but here we will implement the Summer note editor that is a simple WYSIWYG editor using Bootstrap. Summer note is a JavaScript library that helps us to create a WYSIWYG editor. You can download it from either GitHub or the official site.

Using the Code

Summer note uses the open-source libraries jQuery, Bootstrap and Font Awesome. To implement this in an ASP.NET MVC application we will create an MVC project in Visual Studio. First of all we will create bundles required for both JavaScript and CSS files. The following code snippet shows the BundleConfig class.

1. using System.Web.Optimization;
3. namespace BootstrapEditor.App_Start
4. {
5.     public class BundleConfig
6.     {
7.         public static void RegisterBundles(BundleCollection bundles)
8.         {
9.             bundles.Add(new StyleBundle(“~/Content/css”).Include(
10.                      “~/Content/css/bootstrap.css”,
11.                      “~/Content/css/font-awesome.css”,
12.                      “~/Content/css/site.css”
13.                    ));
15.             bundles.Add(new StyleBundle(“~/Content/summernote”).Include(
16.                 “~/Content/summernote/summernote.css”
17.                 ));
19.             bundles.Add(new ScriptBundle(“~/bundle/base”).Include(
20.                “~/Scripts/jquery-1.10.2.js”,
21.                 “~/Scripts/bootstrap.js”
22.                ));
24.             bundles.Add(new ScriptBundle(“~/bundle/summernote”).Include(
25.                “~/Content/summernote/summernote.js”
26.                ));
27.         }
28.     }
29. }

Thereafter we will create a view model (HomeViewModel) that will be bind to the view. The following code snippet shows the HomeViewModel class.

1. namespace BootstrapEditor.Models
2. {
3.     public class HomeViewModel
4.     {
5.         public string Title { get; set; }
6.         public string Content { get; set; }
7.     }
8. }

Thereafter we will create a controller that handles GET and POST requests for a view. The following code snippet shows HomeController.

1. using BootstrapEditor.Models;
2. using System.Web.Mvc;
4. namespace BootstrapEditor.Controllers
5. {
6.     public class HomeController : Controller
7.     {
8.         [HttpGet]
9.         public ActionResult Index()
10.         {
11.             HomeViewModel model = new HomeViewModel();
12.             return View();
13.         }
15.         [HttpPost]
16.         public ActionResult Index(HomeViewModel model)
17.         {
18.             return View(model);
19.         }
20.     }
21. }

Now we will create a view that renders the editor on UI. The following code snippet shows the index view.

1. @model BootstrapEditor.Models.HomeViewModel
2. @section head{
3.     @Styles.Render(“~/Content/summernote”)
4. }
5. class=“panel panel-primary”>
6.     
   class=“panel-heading panel-head”>Add Content
7.     
   class=“panel-body”>
8.         @using (Html.BeginForm())
9.         {
10.             
    class=“form-horizontal”>
11.                 
    class=“form-group”>
12.                     @Html.LabelFor(model => model.Title, new { @class = “col-lg-2 control-label” })
13.                     
    class=“col-lg-9”>
14.                         @Html.TextBoxFor(model => model.Title, new { @class = “form-control” })
15.                     

                </div>

                

class=“form-group”>

                    @Html.LabelFor(model => model.Content, new { @class = “col-lg-2 control-label” })

                    

class=“col-lg-9”>

                        @Html.TextAreaFor(model => model.Content, new { @class = “form-control”, @row = 5 })

                    

Get And Set Description Attribute For A Property

StringBuilder sb = new StringBuilder();

//Get the properties for type T for the headers. T is a class
 PropertyInfo[] propInfos = typeof(T).GetProperties();
 for (int i = 0; i <= propInfos.Length - 1; i++)
 {

 string descriptionAttribute = null;
 object[] attrs = propInfos[i].GetCustomAttributes(true);
 foreach (object attr in attrs)
 {
 DescriptionAttribute descAttr = attr as DescriptionAttribute;
 if (descAttr != null)
 {
 descriptionAttribute = descAttr.Description;
 }
 }

 if (descriptionAttribute != null)
 sb.Append(descriptionAttribute);
 else
 sb.Append(propInfos[i].Name);


 if (i < propInfos.Length - 1)
 {
 sb.Append(",");
 }
 }

sb.AppendLine();

Create CSV from List

public class CsvExport<T> where T: class
    {
        public List<T> Objects;

        public CsvExport(List<T> objects)
        {
            Objects = objects;
        }

        public string Export()
        {
            return Export(true);
        }

        public string Export(bool includeHeaderLine)
        {

            StringBuilder sb = new StringBuilder();
            //Get properties using reflection.
            IList<PropertyInfo> propertyInfos = typeof(T).GetProperties();

            if (includeHeaderLine)
            {
                //add header line.
                foreach (PropertyInfo propertyInfo in propertyInfos)
                {
                    sb.Append(propertyInfo.Name).Append(",");
                }
                sb.Remove(sb.Length - 1, 1).AppendLine();
            }

            //add value for each property.
            foreach (T obj in Objects)
            {               
                foreach (PropertyInfo propertyInfo in propertyInfos)
                {
                    sb.Append(MakeValueCsvFriendly(propertyInfo.GetValue(obj, null))).Append(",");
                }
                sb.Remove(sb.Length - 1, 1).AppendLine();
            }

            return sb.ToString();
        }

        //export to a file.
        public void ExportToFile(string path)
        {
            File.WriteAllText(path, Export());
        }

        //export as binary data.
        public byte[] ExportToBytes()
        {
            return Encoding.UTF8.GetBytes(Export());
        }

        //get the csv value for field.
        private string MakeValueCsvFriendly(object value)
        {
            if (value == null) return "";
            if (value is Nullable && ((INullable)value).IsNull) return "";

            if (value is DateTime)
            {
                if (((DateTime)value).TimeOfDay.TotalSeconds == 0)
                    return ((DateTime)value).ToString("yyyy-MM-dd");
                return ((DateTime)value).ToString("yyyy-MM-dd HH:mm:ss");
            }
            string output = value.ToString();

            if (output.Contains(",") || output.Contains("\""))
                output = '"' + output.Replace("\"", "\"\"") + '"';

            return output;

        }
    }

test--> class name

List<test> list = data;

CsvExport<test> csvExport = new CsvExport<test>(list);
string path = "E://test//test.csv";

Get the index of the object inside an array, matching a condition

 

As of 2016, you’re supposed to use Array.findIndex for this:

a = [{prop1:"abc",prop2:"qwe"},{prop1:"bnmb",prop2:"yutu"},{prop1:"zxvz",prop2:"qwrq"}]
index = a.findIndex(x => x.prop2=="yutu")

It’s supported in GC, FF and Edge, for MSIEs there’s a polyfill on the linked page.

Original answer:

With jQuery:

indexes = $.map(list, function(obj, index) {
    if(obj.prop2 == "yutu") {
        return index;
    }
})

firstIndex = indexes[0]

Without jQuery, slightly more complicated:

indexes = list.map(function(obj, index) {
    if(obj.prop2 == "yutu") {
        return index;
    }
}).filter(isFinite)
