JsRender does not make the transformation for a for loop

问题

The code works according to JsFiddle; http://jsfiddle.net/arame3333/PTWnq/6/

However in my MVC project it renders on the page as;

{{ for BusinessUnitName }} •{"BusinessUnitName":["Design and Build (Technical)","Architectual Design","ICT","Mechanical & Electrical ","Safety Management","Pre-Construction & Bid Preparation"]} {{/for }}

Why would this happen?

The relevant code is;

<ul id="departmentList"><%: Html.DisplayFor(model => model.AdditionalDepartmentList) %></ul>



<script id="DepartmentTemplate" type="text/x-jquery-tmpl">
            {{ for BusinessUnitName }}
                <li>{{:#data}}</li>
            {{/for }}
    </script>



function RefreshDepartments(o) {
        alert("Here are the results");
        var url = '<%: Url.Action("GetAdditionalDepartments", "DataService")%>';
        dataService.getAdditionalDepartments(
            o.EmployeeId,
            RenderDepartments,
            url
        );
    }

    RenderDepartments = function (data) {
        $('#departmentList').empty();
        $('#departmentList').html($('#DepartmentTemplate').render(data));
    };

The data comes from the controller here;

public ActionResult GetAdditionalDepartments(int employeeId)
        {
            var list = AdditionalDepartment.GetBusinessNamesByEmployeeId(employeeId);
            var jss = new JavaScriptSerializer();
            var json = jss.Serialize(new JsonArrayFormat(list.ToList()));
            return new JsonResult
                       {
                           Data = json,
                           JsonRequestBehavior = JsonRequestBehavior.AllowGet
                       };
        }

Edited markup - I cannot dispaly all of it;

    <form method="post" action="/Employee/Edit"><input name="__RequestVerificationToken" value="IM9yFknHf1HKgZbd+UYsyMs9wQKL9dPK8zcRfi5uXTRQl7JvCq/Gr6cVq1wnUnao5Y2IToCDtEb5Vz/KnnxXSEDartM7fE9mQ7Cm7ynsFVE6ST2hhcygJX1ALAP67AXVlBBSf5ozczCctqb8ok+Blw==" type="hidden">

回答1:

<script id="DepartmentTemplate" type="text/x-jquery-tmpl">
    {{ for BusinessUnitName }}
         <li>{{:#data}}</li>
    {{/for }}
</script>

The problem was in 3 whitespaces, it was hard to find problem, because jsfiddle.net example works fine. After all attempts to detect problem I asked arame3333 for htmp-markup, then I just try it and found, that problem in template, correct one:

<script id="DepartmentTemplate" type="text/x-jquery-tmpl">
    {{for BusinessUnitName}}
         <li>{{:#data}}</li>
    {{/for}}
</script>
