Using Html Templates In Javascript

Often while building javascript interfaces, there is a need to render DOM as an HTML template. Frappe Framework uses John Resig's Microtemplate script to render HTML templates in the Desk application.

Note 1: In Frappe we use the Jinja-like {% raw %}{%{% endraw %} tags to embed code rather than the standard <%

Note 2: Never use single quotes ' inside the HTML template.

To render a template,

Create a template html file in your app. e.g. address_list.html
Add it to build.json for your app (you can include it in frappe.min.js or your own javascript file).
To render it in your app, use frappe.render(frappe.templates.address_list, {[context]})

Example Template:

From erpnext/public/js/templates/address_list.js

<p>
    <button class="btn btn-sm btn-default btn-address">New Address</button>
</p>

{% for(var i=0, l=addrlist.length; i<l; i++) { %}
    <hr>
    {%= _("Edit") %}
    {%= addr_list[i].address_type %}

    {% if(addr_list[i].is_primary_address) { %}
        {%= __("Primary") %}
    {% } %}

    {% if(addr_list[i].is_shipping_address) { %}
        {%= __("Shipping") %}
    {% } %}

    {%= addr_list[i].display %}
{% } %}

{% if(!addrlist.length) { %}
    {%= _("No address added yet.") %}
{% } %}
