如何使用MooTools将表单数据转换为对象

Question

I would like to convert an entire form of data to a javascript object.

<form id='myform'>
   <input type='text' name='field1' value='foo'>
   <input type='text' name='field2' value='bar'>
</form>

would convert to a javascript object...

{
   field1: 'foo',
   field2: 'bar'
}

Answer 1

In MooTools you can do easy trick how to convert all forms values into the Object:

var formObjects=$('myform').toQueryString().parseQueryString();

Convert to JSON:

var formJson=JSON.encode(formObjects);

Answer 2

just write your own method, basing it upon the source of the Element.toQueryString - something like this (and i know the method name is rubbish but thats the least of your worries)

Element.implement({
    toJSON: function(){
        var json = {};
        this.getElements('input, select, textarea', true).each(function(el){
            if (!el.name || el.disabled || el.type == 'submit' || el.type == 'reset' || el.type == 'file') return;
            var value = (el.tagName.toLowerCase() == 'select') ? Element.getSelected(el).map(function(opt){
                return opt.value;
            }) : ((el.type == 'radio' || el.type == 'checkbox') && !el.checked) ? null : el.value;
            $splat(value).each(function(val){
                if (typeof val != 'undefined') {
                    json[el.name] = val;
                }
            });
        });
        return json;
    }
});

console.log($("myform").toJSON());

tested and working fine with the example form - http://mootools.net/shell/ZSsVr/ - produces the exact result you have asked for.

Answer 3

I actually like a combination of Dimitar Christoff answer and Trebla:

Element.implement({
    toJSON: function(){
        var j = {};
        Array.each(this.toQueryString().split('&'),function(a){
            var kv = a.split('=')
            j[kv[0]] = kv[1]||'';
        });
        return JSON.encode(j);
    }
});
console.log($('formular_support').toJSON());

http://code.google.com/p/form2js/

check this out, exactly what you're need, but framework independent

Answer 5

MooTools doesn't come with a form serialization tool; i know, that sucks.

However, I've successfully used this stand-alone implementation: form2obj .

One way of doing it. -- Converting it to JSON object

var hm = $('myform').toQueryString();
    hm = '{"'+hm+'"}'; 
    hm = hm.replace(/&/g, '","');
    hm = hm.replace(/=/g, '":"');
    var jsn = JSON.decode(hm); // jsn is ur JSON object.

Convert it to Hash.

Mootools has an object type called Hash. You can convert to that as well by doing the following.

Hash link : http://mootools.net/docs/core/Native/Hash It has set and get methods and you can loop and do stuff, check the link.

var hm = $('myform').toQueryString();

var ar = hm.split('&');
var finalo = new Hash();
ar.each(function(a, aCounter)
{
    var tmp = a.split('=');
    finalo.set(tmp[0], tmp[1]);
});

// finalo is your Hash object. Use the get() method to extract values. Check the link given above.
