element.js

An alternative (to document.createElement) way to dynamically create HTML.

There are several ways to dynamically create HTML. One of them is using multiline strings:

var mylist = `<ul id="mylist">
    <li>Item 1</li>
    <li>Item 2</li>
    <li>Item 3</li>
</ul>`;

Another way is to use + seperated strings:

var mylist = '<ul id="mylist">'+
'    <li>Item 1</li>'+
'    <li>Item 2</li>'+
'    <li>Item 3</li>'+
'</ul>';

One can also use the DOM API to create HTML:

var mylist = document.createElement("ul");
ul.id = "mylist";
var li_1 = document.createElement("li");
li_1.textContent = "Item 1";
var li_2 = document.createElement("li");
//...
mylist.appendChild(li_1);
//...

None of these methods works for me. I needed a more easier, compact, manageable method to dynamically create HTML. Enter element.js.

Syntax

elem(tagName, attributes, children, isHTML)

• tagName : tag name of the element
• attributes : object with property : value pairs (optional, and can be skipped)
• children : an item (that can be a string, number, HTMLElement) or an array of items (optional)
• isHTML : if the children is a string, but contains (or is) HTML, this should be set to true (optional)

Usage

var mylist = elem("ul", {"id" : "mylist"}, [
    elem("li", null, "Item 1"),
    elem("li", "Item 2"),
    elem("li", "Item 3"),
]);

The above code produces the following HTML:

<ul id="mylist">
    <li>Item 1</li>
    <li>Item 2</li>
    <li>Item 3</li>
</ul>

With this method, one can easily manipulate all parts of HTML, and nest as many as one desires.

html2js.js

I've written element.js back in February 24, 2018. Since then, I've been constantly using it. Lately, I've realized that I need another method to convert HTML to JS, and by JS, I mean HTML's element.js equivalent.

Sometimes I create a layout (HTML) and fill the values manually, but these values needs to be entered dynamically. To see the end result, I have to do this process manually, first. Once the HTML is complete, then I have to convert it to JS (elment.js). To help with this process, I've written another function (April 10, 2019) to convert HTML to it's JS (elment.js) equivalent.

For example, let's say I have the following HTML (from StackOverflow):

<div class="-main">
    <a href="#" class="left-sidebar-toggle p0 ai-center jc-center js-left-sidebar-toggle">
        <span class="ps-relative"></span>
    </a>
    <a href="https://stackoverflow.com" class="-logo js-gps-track">
        <span class="-img _glyph">Stack Overflow</span>
    </a>
</div>

If I do html2js(document.querySelector(".-main")), I'll get the following:

"elem("div", {"class":"-main"}, [
    elem("a", {"href":"#","class":"left-sidebar-toggle p0 ai-center jc-center js-left-sidebar-toggle"}, [
        elem("span", {"class":"ps-relative"}),
    ]),
    elem("a", {"href":"https://stackoverflow.com","class":"-logo js-gps-track"}, [
        elem("span", {"class":"-img _glyph"}, "Stack Overflow"),
    ]),
])"

Now, I can get rid of the quotes and use this to create HTML (again :).

HTMLElement.php

I also needed a PHP equivalent of element.js and the HTMLElement (object/class). I'm not sure when I wrote this, but it was probably in mid 2019. I suggest you check it out, too.
