0.3.2

4p_jstemplate

Important if you use NodeJs, jsdom 3.1.2 is required

npm install -S 'jquery@>=2.1'
npm install -S 'jsdom@3.1.2'

(Note that version 3.1.2 of jsdom is required, because as of jsdom version 4.0.0, jsdom no longer works with Node.js. If you use Io.js rather than Node.js, you can use the latest 4.x release of jsdom.) https://github.com/UncoolAJ86/node-jquery https://www.npmjs.com/package/jsdom

            t = tpl.element.html(tpl.render(template_data)); // render to dom

            // tpl.element is a jquery instance of our template element
            tpl.element.find('li').css('color', 'red'); // play with it !

            // handle more complex structure and play with dom
            tpl.renderAfter('table', ''); // render <table>
            for (i = 1; i <= 11; i++) {
                tpl.renderAfter('table-line', {cell: [i, i * i]});  // push rendered data in table                
            }

            var rendered = t.html(); // get html
            res.send(t.html()); // send output     
        });

i've made this template engine, with some idea similar to handlebar, but all presentational template logic is in javascript (we have don't need to learn a new template language again) and it's easy to mix html and javascript, like php with html.

you can reuse your template and define repetitive subpart of it.

in template all data is mapped to a $4p.templateData object and has three method is(), iterate(), v()

$4p.templateData object can contain value mixed value scalar, array, or object

is('with','data','path') is used to traverse data tree, this return a $4p.templateData. that's return the data object corresponding to the data path. if the data path not exist he return a $4p.templateData with null value, so if there no value your code is not breaking and you have not to worry about he data was or was not defined.

iterate() is used to make a loop throught $4p.templateData object if it's contain object or array value

v() return the data value passed in template contained in this object

give me a feedback ;)

The templating part is inspired, like many other, from our Guru: http://ejohn.org/blog/javascript-micro-templating/
