Trying to e to grips with Mustache... the problem here is that the conditional 'if/else' is not working as expected. I am checking in the data if a user is french... if they are then show true, else show false.
Problem
Mustache is pletely ignoring the conditional and displaying both true and false for each table row.
My code
My markup
<!-- -->
<h3>Looping through people</h3>
<table class="table table-striped">
<thead>
<tr>
<th>Name</th>
<th>Age</th>
<th>Language</th>
</tr>
</thead>
<template id="template2">
{{#users}}
<tr>
<td>{{name}}</td>
<td>{{age}}</td>
<td>{{language}}</td>
{{#is_french}}
<td>True</td>
{{/is_french}}
{{^is_french}}
<td>False</td>
{{/is_french}}
</tr>
{{/users}}
</template>
<tbody id="table2"></tbody>
</table>
<!-- -->
My jQuery
$(function(){
/**
* conditional data
*/
template = $('#template2').html();
data = {
'users': [{
name: 'John',
age: 22,
language: 'French',
is_french: true,
},
{
name: 'Billy',
age: 33,
language: 'Anglaise',
is_french: false,
},
{
name: 'Michael',
age: 77,
language: 'Cambodian',
is_french: false,
}]
};
$('#table2').html(Mustache.render(template, data));
});
Question
Why is the if/else not working here?

You provided
template3, while usingtemplate2in view. There is nois_frenchusage intemplate2. – Andrey Commented Feb 14, 2017 at 12:06 - My bad! So sorry about that, copied the wrong block! – Jethro Hazelhurst Commented Feb 14, 2017 at 12:08
- 2 Interesting, but the code you've posted is totally OK, mustache template is fine, and it rendered as supposed. There should be the mistake in another part of code. Could you create fiddle where this problem reproduces? – Andrey Commented Feb 14, 2017 at 12:15
- Trying to get a fiddle going... I updated my OP with the entire document. Strange indeed. – Jethro Hazelhurst Commented Feb 14, 2017 at 12:17

Reset to default 6This is a problem of using template tag, which is actually HTML5 template tag. Using hashes in it makes browser think that this is document fragment. Seems like nested document fragments corrupt Mustache template.
Just change it to script tag, as in mustache manual.
<script id="template2" type="x-tmpl-mustache">
{{#users}}
<tr>
<td>{{name}}</td>
<td>{{age}}</td>
<td>{{language}}</td>
{{#is_french}}
<td>True</td>
{{/is_french}}
{{^is_french}}
<td>False</td>
{{/is_french}}
</tr>
{{/users}}
</script>
