Jsrender: Browser does not respect template markup

[ba1dr]

See https://jsfiddle.net/8vfesbgf/1/

<div id="alltemplates" class="hidden">
<code id="tpl_fieldtype">
    <div class="form-group">
        <label>{{:fieldname}}</label>
        <select class="fieldtype form-control" data-name="{{:fieldname}}">
            {{for allfieldtypes}}
            <option value="{{:ftype}}" {{ if ftype == fieldtype }}selected{{/if}}>{{:ftype}}</option>
            {{/for}}
        </select>
    </div>
</code>
</div>

See 3 commented blocks in the fiddle - nothing of these returns correct content.
It seems browser does not process this block as is.
I see it as:

 {{for allfieldtypes}}
    <option if}}="" }}selected{{="" fieldtype="" ftype="=" if="" {{="" value="{{:ftype}}">{{:ftype}} </option>
{{/for}} 

How do I render this template?

Ubuntu 15.10: Firefox 46.0.1 / Chromium 50.0.2661.102

You need to call .render with the data you need on the template.

fielddesc_tpl = $.templates('#tpl_fieldtype');

var tpl_data = {
  fieldname: 'test',
  allfieldtypes: [
    {ftype: 'ft1'},
    {ftype: 'ft2'},
    {ftype: 'ft3'},
    {ftype: 'ft4'}
  ]
}

console.log(fielddesc_tpl.render(tpl_data));

Kind regards.

Really? Have you ever tried to do this in jsfiddle?
I get these lines:

                <option value="ft1" {{="" if="" ftype="=" fieldtype="" }}selected{{="" if}}="">ft1</option>

I would start by removing the space between the {{ and "if" in your template so that the "if" is immediately adjacent to the curly brackets (i.e., {{if x == y}}{{:ftype}}{{/if}}). The browser is converting your "if" to property of a tag if=""

[grma1]

the main problem was, that the code block is parsed by the html engine.

try the following:

<div id="alltemplates" class="hidden">
    <script type="text/x-jsrender" id="tpl_fieldtype">
        <div class="form-group">
            <label>{{:fieldname}}</label>
            <select class="fieldtype form-control" data-name="{{:fieldname}}">
                {{for allfieldtypes}}
                <option value="{{:ftype}}" {{if ftype === fieldtype}}selected{{/if}}>{{:ftype}}</option>
                {{/for}}
            </select>
        </div>
    </script>
</div>

If you are doing this in a browser then your template should be in a script tag. And then you need to call render and insert the resulting string in to the dom.

JSRender does not somehow make the browser dom understand it's {{tag}} notation. You place the template in script tag so that the browser will ignore it.
Then you use javascript to render the template and insert it into the dom where you would like.

var model = {
hello: 'world'
};

var rendered = $.template('#helloworld').render(model);

$('body').html(rendered);

Thanks everybody! The issue is solved, in fact I used <code> instead of <script> tag.. Isn't html became too complex? :)
The note about <script> tag should be mentioned in RED BOLD FONT on each page.

Thanks all, for the explanations...

The information about script blocks is in a few places in the docs: http://www.jsviews.com/#search?s=script%20block. (@ba1dr - I'm not sure which topics you had seen).
