CHANGELOG

Check changelog for more informations check

How to?

Import first

// commonjs
var e = require('eyjs');

// ESM
import e from "eyjs";

Selecting an element

// div id="bar"
let bar = e("div#bar");
// all spans with class="list-item"
let listItem = e("span.list-item");
// all elements with class ".fools"
let fools = e(".fools");
// using ! only return the first occurence
let firstButton = e(".btns!");

Creating elements

let baron = e("<div>",{
        text: "leave",
        parent: bar,
        class: "btn button_dark", // also accepts array for multiple class setting at once or string concatenation of them with spaces between
        data: { // setting dataset values
            index: 12,
            manMap: "off"
        }
    },{ 
        backgroundColor: "red", 
        color: "white"
    })

Extra functionalities

// the most amazing functionalities is that u can chain calls
baron
    .hide() // display: none
    .show(customStyle); // display: inline-block or custom style

baron
    .data("name","yousef neji"), // more powerfull than dataset, using WeakMaps!
    .data("name"); // deleting a key

baron.attr("contentEditable","true"); // manipulating atributes
baron.attr("style",false); // `false` will remove the attribute `style`
baron.rAttr("style"); // or you could simply use rAttr
baron.attr("data-index"); // setting or getting dataset values

baron.on("click",cb); // events handling
baron.click(cb); // triggering or handling events

baron.child(0); // getting child number 0
baron.childlen // getting children length

baron.client("width") // get client specific informations "width" "height" "left" or "top"

Redefine set/get features of .text and .val

You can modify the way you use .text and .val using .redefine

let customInp = e('div',{ class: "custom-inp", parent: form });

customInp.redefine("text",(action, value, elm)=>{
    if(action == "set"){
        return value.join(" || ");
    } else if(action === "get") {
        return value.split(" || ");
    }
})

Serializing form elements fn `.serialize`( param : opts )

Serializing is transcoding form inputs data into an appropriate string format that you can send over the network to the server.

The function will select all sub inputs, select, textarea elements and return their values, in order to narrow the selection you can pre-define the inputs you want to select in opts.inputs, which also offers custom-input & custom-getter as follow:

custom-inputs: When your form contains custom inputs(div with special input features for example), you define them in the opts.inputs by a selector like .special-input, #specialinp... etc.
custom-getters: the naming convention is only for explainatory purpose, this feature basically nameless, It's the ability to provide a custom way to subtract the data of certain input/custom, by defining a function with the name of that input/custom, here's how u do it:
- opts.[fieldname]: (inp) => inp.child(0).val();

<form class="createUser">
    <input type="text" name="username">
    <input type="password" name="password">
    <div data-name="hooby" class="custom-input" contentEditable>
        user hobbies: 
            <div class="list">
                <span>singing</span>
                <span>dancing</span>
                <span>writing</span>
            </div>
    </div>
    <button>submit</button>
</form>

let form = e('form.createUser');

let opts = {
    // optionally identify the inputs to serialize adding custom inputs
    inputs: ['input','select','.custom-input'],
    hobby: (inp)=>{
        let v = [];
        // this will select the custom-input .list>span spans
        // get their values and push it into `v` array.
        inp.find(".list>span",true).each(span => v.push(span.textContext));
        // then return the value as string by joining it using ','
        return v.join(',');
    }
}

let data = form.serialize(opts);
// send data over network using jcall/fetch/axios ...

`~Models~`

description: models used to create elements similar to react components except easier to manager, you can create basic blueprint using e("model:youModelName", blueprint), later on, you use the returned constructor over and over when ever the need calls!
how it works:
- include the "model:_model_name_".
- define your blueprint:
  - a blueprint is an object containing nested objects that defines each component of your model,
  - a blueprint element is formed by
    
    [tagname.classname1.classname2: _index - default_value],
    
    where _index(must contain the _) represent a datacell to display data later, and default_value will be set if no data passed.
Usuage:

let failMessage = e("model:FailMessage", {
   "div.head": {
       "div.title: _title - Big Fancy Title": {},
       "div.close": {}
   },
   "div.body": {
       "p.message: _message - no message": {},
       "div.details: _details - no details": {},
       "div.actions": {
           "button.ok: _ok - OK": {},
           "button.cancel: _cancel - Cancel": {}
       }
   }
})

// do ajax stuff
fetch()
.then()
.catch((e)=>{
   // create a new instance
   let error = failMessage({
       parent: document.body // append using parent attribute
       _title: "Backend error - " + e.name,
       _message: e.message,

       // try to avoid using this attribute unless 
       // you want to mess up with your model
       // text: "some text",
       // html: "some html",
   });
   // or append later 
   error.appendTo(document.body);
   // you may pre-create the error in earlier stage! before the fetch()
   // and refresh it content using .refresh function
   error.refresh({
       _title: "Backend error - " + e.name,
       _message: e.message
   })
   // refresh also accepts an attribute `default`(set true by default)
   // which adjut whether to update all datacells of the model
   // or only update the one passed through the function
   // EXAMPLE:
   error.refresh({
       _title: "Other Error - " + e.name
   })
   // this will update _title to the new value and also update 
   // the other datacells like `_message` `_details` ...
   // but since they're not passed they will display the default values
   // from the constructor up at the top!
   // `_message` => no message
   // `_details` => no details
   // ...
   // unless you passed (default: false)
   error.refresh({
       _title: "Other error - " + e.name,
       default: true
   })
   // in this case only _title will be changed!
})
