RenderJS

Note

(Formerly known as PDRenderKit, renamed to RenderJS starting from version 2.0.0)

RenderJS is a lightweight tool focusing on extending JavaScript native object prototypes, providing powerful DOM manipulation and data processing methods.

Feature

Simplified DOM Manipulation

Achieve complex DOM operations with concise chainable syntax.

Enhanced Querying

Quickly retrieve elements with simplified selector syntax, supporting both single and multiple element selection.

Built-in Extensions

Predefined prototype extensions accelerate development across various scenarios.

Plug and Play

Seamlessly integrates with existing JavaScript projects and supports modern browsers.

Installation

Install via npm

npm i @pardnchiu/renderjs

Overview

Extension

• Before

  let section = document.createElement("section");
  section.id = "#test";
  document.body.appendChild(section);
  
  let button = document.createElement("button");
  button.style.width = "10rem";
  button.style.height = "2rem";
  button.style.backgroundColor = "steelblue";
  button.style.color = "fff";
  button.onclick = function(){
      alert("test")
  };
  button.innerHTML = "<span>test</span> button";
  section.appendChild(button);
  
  let svg = document.createElement("span");
  span.classList.add("svg");
  span.setAttribute("path", "https://xxxxxx");
  section.appendChild(span);
  
  let img = document.createElement("img");
  img.classList.add("lazyload");
  img.dataset.src = "https://xxxxxx";
  section.appendChild(img);
  
  let input = document.createElement("input");
  input.placeholder = "type";
  input.type = "email";
  section.appendChild(input);

• After

  document.body._child(
      "section#test"._([
          "button"._({
              style: {
                  width: "10rem",
                  hright: "2rem",
                  backgroundColor: "steelblue",
                  color: "#fff"
              }
          }, [
              // or "<span>test</span> button"
              "span"._("test"),
              " button"
          ])._click(function(){
              alert("test")
          }),
          "span.svg:._({ path: "https://xxxxxx" }),
          // No Lazy Loading => "img"._("https://xxxxxx"),
          "img"._({ lazyload: "https://xxxxxx" }),
          "input@email type"._()
      ])
  );
  
  _Listener({
      svg: true,     // Add SVGListener, convert span.svg to svg tag
      lazyload: true // Add Lazy Listener, Lazy Loading images
  });

• Get Element

  • Before

    document.getElementById("test");
    document.querySelector("div.test");
    document.querySelectorAll("div.test");
    document.querySelector("input[name='test']");

  • After

    "test".$;
    "div.test".$;
    "div.test".$all;
    "input[name='test']".$;

• Add Element

  • Before

    <div class="test" style="width: 5rem; height: 80px;" test="test">
        <button>
            <img src="https://xxxxxx">
        </button>
    </div>

  • After

    "div.test"._({
        style: {
            width: "5rem",
            height: 80,
        },
        test: "test"
    }, [
        "button"._([
            "img"._("https://xxxxxx")
        ])
    ]);

Simplified Frontend Framework

Note

RJS is a simplified frontend framework based on QuickUI, designed for specific projects

• Renders using non-vDOM technology, enhancing performance and reducing complexity.
• Removes automatic listening and updating, giving developers manual control over update processes.
• Introduces renew() function to support precise updates of data and events.

Attribute	Description
{{value}}	Inserts text into HTML tags and automatically updates with data changes.
:path	Used with the temp tag to load HTML fragments from external files into the current page.
:html	Replaces the element's innerHTML with text.
:for	Supports formats like item in items, (item, index) in items, (key, value) in object. Iterates over data collections to generate corresponding HTML elements.
:if :else-if :elif :else	Displays or hides elements based on specified conditions, enabling branching logic.
:model	Binds data to form elements (e.g., input), updating data automatically when input changes.
:[attr]	Sets element attributes, such as ID, class, image source, etc. Examples: :id/:class/:src/:alt/:href...
:[css]	Sets element CSS, such as margin, padding, etc. Examples: :background-color, :opacity, :margin, :top, :position...
@[event]	Adds event listeners that trigger specified actions upon activation. Examples: @click/@input/@mousedown...

• Initializing RJS

  const app = "(ComponentID)".RJS({
      data: {
          // Define data
      },
      event: {
          // Define events
      },
      when: {
          before_render: function () {
              // Executes before rendering (can stop rendering)
              // return false 
          },
          rendered: function () {
              // Executes after rendering
          }
      }
  });

• Updating RJS

  app.renew({
      // data: Only include data items to update; unmentioned items retain initial values.
      // event: Only include event items to update; unmentioned items retain initial values.
      // when: Only include lifecycle logic to update; unmentioned items retain initial logic.
  });
