README

🔧 Component for Nette framwork which helps with creation of lazy ajax loaded components.

Introduction

Component which renders empty in the beggining and is populated by signal request.

Installation

Install package using composer

composer require infinityloop-dev/lazy-component

Dependencies

How to use

Create new component and extend \Infinityloop\LazyComponent\LazyComponent instead of \Nette\Application\UI\Control.
Trigger handleLoadComponent to load and redraw component.
Use macro {control componentName} to render your component as you would normally.
Additionaly use {control componentName:loadComponentLink} to get URL for loadComponent signal.
- Useful for rendering URL (eg. into data attributes) so you can easily trigger signal from javascript.
Make sure LazyCompoennt::render() method is called if you choose to override it.
- Preferably use beforeRender() to pass variables into template.
- beforeRender() method is not called when empty template is used (when component is not loaded).
Template for your component is automaticaly deduced to be have same name (and path) as your .php file.
- File extension is simply swapped to .latte.
By default the FontAwesome 5 spinner is used as placeholder. Override EMPTY_TEMPLATE constant to use different empty template file.

Example lazy tab content

Tab header:

<li class"tab" data-load-component="{control myComponent:loadComponentLink}">Tab name</li>

Tab content:

<div class="tab-content">
    {control myComponent}
</div>

JQuery ajax request on click:

$(".tab[data-load-component]").one('click',function (event) {
    const link = $(this).data("load-component");
    $.nette.ajax({
        method: 'GET',
        url: link,
    });
});

Load event is executed only once (jqery.one).
