HTML is a JavaScript "class" which simplify HTMLElement construction with a JSON Structure

Below, an example of HTML code generation from a simple JSON structure :

new HTML().compose({
    name: "div",
    classList: ["cl1", "cl2"],
    attributes:{
        style: "background-color: red;",
        "data-attr": "attr-value"
    },
    properties: {
        innerHTML: "Text with HTML balise"
    }
});

Will result :

<div class="cl1 cl2" style="background-color: red;" data-attr="attr-value">
Text with HTML balise
</div>

The compose method will generate the corresponding HTMLElements and return.

var structure = {};
new HTML().compose(structure);

Below, the algorithmic declaration :

STRUCTURE strListJSON
    name:  typeof String
    value: typeof Mixed
END STRUCTURE


STRUCTURE strListFunction
    function:   typeof function (callable)
    args:       typeof Array
END STRUCTURE


STRUCTURE strBuildHTML -- All attributes are optionnal
    name:       typeof String                   -- Stand for resulting tag name
    element:    typeof HTMLElement              -- to pass an existing HTMLElement
        (priority on name)
    
    classList:  typeof Array of String          -- List of CSS classes to append
    attributes: typeof Object using strListJSON -- List of HTML attribute to append
    properties: typeof Object using strListJSON -- List of HTML properties to append
    children:   typeof Array of strBuildHTML    -- Childs element to build and to append
    functions:  typeof Array of strListFunction -- List of function to execute before 
        returning generated HTMLElement
END STRUCTURE

The attribute name of the structure strBuildHTML define the HTML tag to build. If the attribute name is missing, the default tag is div.

new HTML().compose({name: 'section'});

Will result :

<section></section>

The attribute element of the structure strBuildHTML allows to bind an existing HTMLElement to manipulate with the class HTML.

<div id="article" class="bg-red">
    <h1>Title</h1>
    <p>Paragraph</p>
</div>

var element = document.querySelector('#article');

new HTML().compose({
    element: element,
    classList: ['font-size', 'text-decoration']
});

Will result :

<div id="article" class="bg-red font-size text-decoration">
    <h1>Title</h1>
    <p>Paragraph</p>
</div>

The attribute classList of the structure strBuildHTML serves to add values provided in the HTML attribute class.

new HTML().compose({classList: ['class-1','class-2', 'class-3']});

Will result :

<div class="class-1 class-2 class-3"></div>

The attribute attributes of the structure strBuildHTML allows you to add any HTML attribute with specified value (of type String or Number )

new HTML().compose({name: 'th', attributes: {colspan: 2}});

Will result :

<th colspan="2"></th>

The attribute properties of the structure strBuildHTML is similare to attributes. It allows you to add/edit HTMLElement properties as-in a JavaScript script

new HTML().compose({properties: {textContent: 'Text Here'}});

Will result :

<div>Text Here</div>

The attributes children of the structure strBuildHTML is a list of declaration of type strBuildHTML which will be appended to the current element.

new HTML().compose({
    name: 'table',
    children: [
        {
            name: 'tr',
            children: [
                {name: 'th', properties: {textContent: '#'}},
                {name: 'th', properties: {textContent: 'First Name'}},
                {name: 'th', properties: {textContent: 'Last Name'}},
                {name: 'th', properties: {textContent: 'Age'}}
            ]
        }
    ]
});

Will result :

<table>
    <tr>
        <th>#</th>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Age</th>
    </tr>
</table>
