How to append a C# formatted html

Question

I have a button that append's the same layout of html but I have a problem taking the select values with it. My html is:

<div id="degreePlusSign">Button</div>
<div class="padding">
    <div class="col-md-5 col-xs-12">
        <label for="prefix" class="sr-only">Degrees</label>
        <select class="form-control marginBottom15">
        @{
            foreach (var degree in ViewBag.NewDegrees)
            {               
            <option value="@degree.DegreeID" selected>@degree.DegreeName</option>
            }
          }
         </select>
         <span class="glyphicon form-control-feedback"></span>
     </div>
</div>

JS:

$('#degreePlusSign').on('click', function () {
    $(this).closest('.padding').append('<div class="padding mBottom"><i class="fa fa-times-circle fa-2x" aria-hidden="true"></i><div class="col-md-5 col-xs-12"><select class="form-control marginBottom15">@{foreach (var degree in ViewBag.NewDegrees){<option value="@degree.DegreeID" selected>@degree.DegreeName</option>}}</select><span class="glyphicon form-control-feedback"></span></div><div class="col-md-7 col-xs-12"><input class="form-control" placeholder="Major/Area of Study" type="text" /></div></div>');
});

Basically it recreates the html, but my problem is I'm using a foreach loop to bring in the values from the backend and it will only work with the inital container, not the duplicated containers afterwards. How do I keep the values on every duplication with the append jquery?

Answer 1

You have got two options:

1. Spit options values (formatted) from C# and keep in a JS variable:

{
       var opts=new StringBuilder();
       var sel="selected";
       foreach(var d in ViewBag.NewDegrees)
       {
           opts.Append($"{d.DegreeName}");
           sel="";
       }
    }

Then somewhere down store it into a js variable:

var optsList="@(opts)";

Now you can use append new HTML as:

$('#degreePlusSign').on('click', function () {
    $(this).closest('.padding').append('<div class="padding mBottom"><i class="fa fa-times-circle fa-2x" aria-hidden="true"></i><div class="col-md-5 col-xs-12"><select class="form-control marginBottom15">'+

optsList/*THIS IS THE VALUE WE STORED FROM C# CODE*/

+'</select><span class="glyphicon form-control-feedback"></span></div><div class="col-md-7 col-xs-12"><input class="form-control" placeholder="Major/Area of Study" type="text" /></div></div>');
});

2. Clone the generated select element and use that:

$('#degreePlusSign').on('click', function () {
    /*CLONE EXISTING SELECT ELEMENT. YOU MAY WANT TO PUT AN ID FOR SELECTION*/
    var cl=$("select.form-control.marginBottom15").clone();

    var d = $("").addClass("padding mBottom")
              append("").addClass("fa fa-times-circle fa-2x").attr("aria-hidden",'true');

    /*APPEND CLONED SELECT TO INNER DIV*/
    d.append("").addClass("col-md-5 col-xs-12").append(cl);
    d.append(cl);

    d.append("").addClass(glyphicon form-control-feedback");
    d.append("").addClass("col-md-7 col-xs-12").append("").addClass("form-control")
    .attr("placeholder","Major/Area of Study").attr("type","text");

    $(this).closest(".padding").append(d);    
});`

Hope you will be able fix any jQuery mess. I haven't used it since long.

.clone was what I was looking for. $('.padding').clone().append('.padding');
