Synopsis
Some times all you want is a simplier way to transform your html forms in json or js objects. This is what this projet is about.
Code Example
Consider a simple markup like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<form action="#" id="myForm">
<input type="checkbox" name="checkbox" value="checkbox" checked disabled>
<input type="color" name="color" value="#FF0000" disabled>
<input type="date" name="date" value="2017-11-24" disabled>
<input type="datetime" name="datetime" value="2017-11-24T04:30" disabled>
<input type="datetime-local" name="datetime-local" value="2017-11-24T04:30" disabled>
<input type="email" name="email" value="[email protected]">
<input type="file" name="file">
<input type="hidden" name="hidden" value="hidden">
<input type="image" src="image" alt="image input">
<input type="month" name="month" value="2017-11">
<input type="number" name="number" value="12345">
<input type="password" name="password" value="password">
<input type="radio" name="radio" value="radio" checked>
<input type="radio" name="radio" value="radio2">
<input type="range" name="range" value="35">
<input type="search" name="search" value="search">
<input type="tel" name="tel" value="(61)99304-1307">
<input type="text" name="text" value="text">
<input type="time" name="time" value="04:30">
<input type="url" name="url" value="http://www.google.com">
<input type="week" name="week" value="2017-W47">
<input type="reset" value="reset">
<input type="button" value="button">
<input type="submit" value="">
<textarea name="textarea" cols="30" rows="10">textarea</textarea>
<select name="select">
<option value="select" selected>select</option>
</select>
</form>
</body>
</html>
Then all you have to do is create a new instance of FormJsonizer and call the serializer method. Don't forget passing the form object as the first parameter! Take a look:
const jsonizer = new FormJsonizer();
const form = document.getElementById('myForm');
const json = jsonizer.serialize(form);
And voilà, you get this json:
{
"email": "[email protected]",
"hidden": "hidden",
"month": "2017-11",
"number": "12345",
"password": "password",
"radio": "radio",
"range": "35",
"search": "search",
"tel": "(61)99304-1307",
"text": "text",
"time": "04:30",
"url": "http://www.google.com",
"week": "2017-W47",
"textarea": "textarea"
}There is some other tricks you can do:
If you whant disabled fields to be included in the output just say it when you instanciate the class, pretty nice hã?
const jsonizer = new FormJsonizer({ includeDisabled: true })And if you preffer output a JS object instead of a json there is no problem...
const jsonizer = new FormJsonizer({ json: false });Motivation
This is a pretty simple project, and learning and having fun was the main motivation bahind this code, and of course, trying to solve some problems of the real world.
