Get all information for login from form using javascript

Question

Is it possible to get all the necessary information to log in using javascript?

I have a form object:

var form = getForm(); //some special function :-)
console.log(form.action); // "https://example.com/login"
console.log(form.method); // post
//next step get inputs for login name and psw, for example: name and ps

So, I can simulate post

https://example.com/login
post
name: admin
psw: harrypotter

BUT! Some web pages have another secret attribute stored in form html, like this:

action: login

I am looking for some automated method which can extract all informations need for login.

Do you have some idea how??

Thanks for any help.

You can use iteration to look at all of the properties of a element. You can then save these values to an array and then access the array to find values, such as action.

for (var i = 0; i < elem.attributes.length; i++) {
    var attrib = elem.attributes[i];
    if (attrib.specified) {
        console.log(attrib.name + " = " + attrib.value);
    }
}
